The Hong Kong Arbitration Matrix: A Comprehensive Guide to Cross-Border Dispute Resolution and Court-Assisted Interim Measures in 2026

Introduction: The Premier Bridge Between Common Law and Civil Law Commercial Order

In the global architecture of international commercial arbitration (ICA), very few arbitral seats command the institutional resilience, doctrinal sophistication, and cross-border enforcement reach of the Hong Kong Special Administrative Region (HKSAR). Operating under the constitutional framework of "One Country, Two Systems" enshrined in the Basic Law of the Hong Kong Special Administrative Region, Hong Kong remains the only common law jurisdiction within the People's Republic of China (PRC). Its bilingual legal system, independent judiciary vested with the power of final adjudication through the Hong Kong Court of Final Appeal (HKCFA), and deep bench of international commercial barristers, solicitors, and arbitrators have positioned it at the forefront of global dispute resolution alongside London, Singapore, Paris, and Geneva.

For corporate counsel, international arbitration practitioners, legal researchers, and law students across Hong Kong, Singapore, the United Kingdom, the United States, and Mainland China, the year 2026 marks a period of extraordinary dynamism in Hong Kong's arbitral ecosystem:

• Record-Breaking Institutional Caseloads and Dispute Values: According to the statistical report released by the Hong Kong International Arbitration Centre (HKIAC) in February 2026, total amounts in dispute across all HKIAC arbitration filings surged by nearly 20 percent to an all-time record of HK$126.2 billion (approximately US$16.2 billion) across 388 new arbitrations (within 582 total dispute resolution filings), with administered arbitrations accounting for HK$117.7 billion (US$15.1 billion) and an average dispute value of HK$418.8 million (US$53.7 million).

• The September–October 2026 Arbitration Ordinance Reform Consultation: Following the establishment of the Working Group on Arbitration Law Reform in October 2025, the Hong Kong Department of Justice (HKDoJ) launched a landmark stakeholder consultation on 28 September 2026 (running through 27 October 2026), examining 25 key legislative issues across speed, convenience, confidentiality, scope of application, and fairness under the Arbitration Ordinance (Cap. 609), with an amendment bill targeted for introduction to the Legislative Council in early 2027.

• Mature Operation of the 2024 HKIAC Administered Arbitration Rules: Having entered into force on 1 June 2024, the 2024 HKIAC Rules are now the standard procedural engine for Hong Kong arbitrations, equipping tribunals and HKIAC with sweeping powers to protect the integrity of the arbitral process, curb "guerrilla tactics" such as late counsel changes, mandate considerations of diversity and environmental impact, and enhance preliminary powers for emergency arbitrators.
• Unmatched Utility of the Mainland-Hong Kong Interim Measures Arrangement: Since entering into force on 1 October 2019 through the latest 2026 reporting cycle, HKIAC has processed 178 applications to Mainland Chinese courts seeking preservation of assets, evidence, and conduct totaling RMB 45.3 billion, resulting in 126 granted asset preservation orders securing RMB 30.8 billion (approximately US$4.6 billion), with over half of recent applications targeting assets held in Mainland China by non-Mainland foreign entities.

This treatise provides an exhaustive, doctrinally rigorous, and practically oriented analysis of the Hong Kong arbitration framework in 2026. It examines the statutory mechanics of the Arbitration Ordinance (Cap. 609), the procedural innovations of the 2024 HKIAC Rules, the cross-border preservation architecture connecting Hong Kong and Mainland China, the financing options under Part 10A and Part 10B of the Ordinance, and the definitive 2023–2026 jurisprudence of the Hong Kong Courts.

I. The Statutory Architecture: The Arbitration Ordinance (Cap. 609) and the 2026 Reform Horizon

1. The Unified UNCITRAL Model Law Regime

Enacted in November 2010 and effective since 1 June 2011, the Arbitration Ordinance (Cap. 609 of the Laws of Hong Kong) abolished the historical bifurcation between domestic and international arbitration regimes under the repealed Cap. 341. In its place, Cap. 609 established a unitary statutory regime governed almost entirely by the 1985 UNCITRAL Model Law on International Commercial Arbitration as amended in 2006.

Rather than paraphrasing the UNCITRAL Model Law and risking divergence from international interpretive consensus, the Hong Kong legislature adopted a direct incorporation methodology: each operative article of the 2006 UNCITRAL Model Law is reproduced verbatim inside particular sections of the Arbitration Ordinance and explicitly given the force of law in Hong Kong, subject only to specific Hong Kong modifications and additions.

Under Section 3 of the Arbitration Ordinance, the object of the statute is to facilitate the fair and speedy resolution of disputes by arbitration without unnecessary expense. This overarching policy rests on two mandatory statutory pillars:

1. Party Autonomy (Section 3(2)(a)): Subject to the observance of the safeguards that are necessary in the public interest, the parties to a dispute should be free to agree on how the dispute should be resolved.

2. Minimal Judicial Intervention (Section 3(2)(b)): The court should interfere in the arbitration of a dispute only as expressly provided for in the Ordinance.

2. Key Structural Departures and Enhancements Beyond the Model Law

While faithful to the 2006 UNCITRAL Model Law, the Hong Kong Arbitration Ordinance incorporates several advanced statutory mechanisms tailored for sophisticated international commerce:

• Statutory Confidentiality (Section 18): Unlike the UNCITRAL Model Law and the English Arbitration Act 1996 (until recent reforms), which historically left confidentiality to implied common law obligations or institutional rules, Section 18(1) of Cap. 609 imposes an express statutory prohibition: unless otherwise agreed by the parties, no party may publish, disclose, or communicate any information relating to the arbitral proceedings under the arbitration agreement or an award made in those proceedings, subject only to carefully defined exceptions (such as protecting or pursuing a legal right before a court, enforcing or challenging an award, or making disclosures required by law or to professional or financial advisers). Complementary to Section 18, Section 16 prescribes that court proceedings under the Ordinance are to be heard otherwise than in open court (in chambers) unless the court orders an open hearing on the application of a party or where satisfied that the case ought to be heard in open court.

• Express Arbitrability of Intellectual Property Disputes (Part 11A, Sections 103A–103J): Introduced in 2018, Part 11A removes any doctrinal doubt regarding whether intellectual property (IP) disputes involving validity, subsistence, ownership, infringement, or compensation of patents, trademarks, copyrights, or registered designs are capable of settlement by arbitration. Under Section 103D, an IP dispute may be resolved by arbitration whether it is the main issue or an incidental issue, and an arbitral award determining the validity of a registered IP right binds the contracting parties inter partes without undermining the sovereign registration authority of the Registrar of Patents or Trademarks as against third-party strangers. 

• Emergency Arbitrator Relief Enforceable as a Court Order (Part 3A, Sections 22A–22B): Added in 2013, Part 3A gives full statutory recognition to Emergency Arbitrators appointed under institutional rules prior to the constitution of the arbitral tribunal. Under Section 22B(1), any emergency relief granted, whether in or outside Hong Kong, by an emergency arbitrator is enforceable in the same manner as an order or direction of the Hong Kong Court of First Instance (with the leave of the Court), provided that if the emergency relief is granted outside Hong Kong, it falls within a curated statutory list of preservation and interim measures under Section 22B(2). 

• Retained Opt-In Provisions for Domestic Construction and Subcontracts (Schedule 2): To accommodate local construction industry practices that historically relied on domestic court oversight, Schedule 2 of Cap. 609 preserves optional provisions including consolidation of arbitrations by the court, determination of preliminary points of law by the court, challenges to awards for serious irregularity (Section 4 of Schedule 2), and appeals on a question of law (Section 5 of Schedule 2) which apply only if the parties expressly opt into Schedule 2 in their arbitration agreement (or via deemed automatic opt-in for domestic subcontracts where the main contract opts in).

3. The September–October 2026 Department of Justice Consultation on Reforming Cap. 609

Maintaining Hong Kong's competitive edge against rival seats particularly following the enactment of the United Kingdom Arbitration Act 2025 (which reformed English rules on the governing law of the arbitration agreement, summary disposal, and jurisdictional challenges under Section 67) and ongoing updates in Singapore and Mainland China (whose revised PRC Arbitration Law took effect on 1 March 2026) has prompted the Hong Kong Government to initiate a comprehensive review of Cap. 609.

In October 2025, the Hong Kong Department of Justice (HKDoJ) established the Working Group on Arbitration Law Reform, comprising leading arbitration practitioners, institutional leaders (including HKIAC Secretary-General Joanne Lau), academics, and government counsel. On 28 September 2026, the HKDoJ formally launched its public stakeholder consultation (open until 27 October 2026), targeting the introduction of an amendment bill into the Legislative Council in early 2027.

The 2026 Consultation Paper evaluates 25 distinct reform issues structured around four overarching thematic pillars:

1. Speed and Convenience: Examining statutory recognition of summary disposal powers, streamlining procedures for enforcing awards, and refining the interplay between tribunal-ordered and court-ordered interim measures.

2. Confidentiality: Reviewing whether the statutory exceptions to confidentiality in Section 18 and court reporting anonymity protocols require calibration in light of contemporary global transparency and fraud-prevention standards.

3. Scope of Application: Addressing conflict-of-laws certainty regarding the law governing the arbitration agreement specifically evaluating whether Hong Kong should adopt a statutory default rule (similar to Section 6A of the English Arbitration Act 1996 as introduced by the 2025 UK Act) providing that, in the absence of an express party choice of law specifically for the arbitration agreement, the law of the seat of arbitration governs the arbitration agreement rather than the common law presumptive rule of the law of the underlying matrix contract articulated by the UK Supreme Court in Enka Insaat ve Sanayi AS v OOO Insurance Company Chubb [2020] UKSC 38.

4. Fairness and Justice (Including Issue 25 on Appeals on Points of Law): Assessing arbitrator duties of disclosure, immunity, and whether to retain the current opt-in approach to appeals on points of law under Schedule 2 or transition toward an opt-out mechanism.

II. Institutional Excellence: The 2024 HKIAC Administered Arbitration Rules in Practice

At the institutional core of the Hong Kong arbitration matrix stands the Hong Kong International Arbitration Centre (HKIAC), established in 1985 as an independent, non-profit company limited by guarantee. Consistently ranked among the top three most preferred arbitral institutions globally, HKIAC is designated under Section 13(2) of the Arbitration Ordinance as the statutory default appointing authority in Hong Kong-seated ad hoc and institutional arbitrations where parties fail to agree on the number of arbitrators or the appointment procedure.

On 1 June 2024, the 2024 HKIAC Administered Arbitration Rules entered into force, superseding the 2018 edition for all arbitrations commenced on or after that date. Unlike earlier transitions, Article 1.5 of the 2024 Rules simplified temporal application by eliminating complex historical carve-outs: unless the parties agree otherwise, the 2024 Rules apply in their entirety including provisions on emergency arbitration, early determination, consolidation, and single arbitration under multiple contracts regardless of whether the underlying arbitration agreement was entered into before or after 1 June 2024.

Practitioners drafting contracts or conducting proceedings in 2026 must master six landmark features of the 2024 HKIAC Rules:

1. Safeguarding Efficiency and Integrity: Power to Exclude New Legal Representatives (Article 13.8 & 13.9)

In high-stakes international arbitration, a recurring guerrilla tactic involves a respondent appointing a new barrister or law firm shortly before an evidentiary hearing with the calculated intention or foreseeable consequence of creating a conflict of interest with a sitting member of the arbitral tribunal, thereby forcing the arbitrator's resignation and derailing the timetable.

• Under Article 13.8, once the arbitral tribunal is constituted, a party must promptly communicate any proposed change or addition to its legal representatives to all other parties, the tribunal, and HKIAC.

• Under Article 13.9, the arbitral tribunal is expressly empowered, after consulting with the parties, to take any measure necessary to avoid a conflict of interest of an arbitrator arising from a change or addition in party representation, including excluding the proposed new party representatives from participating in all or part of the arbitral proceedings.

2. Expanded Powers in Multi-Party, Multi-Contract, and Concurrent Proceedings (Articles 27, 28, 29, & 30)

Commercial transactions in the Asia-Pacific region particularly private equity investments, joint ventures, maritime charters, and infrastructure chains rarely fit inside a single bilateral contract. In 2025 alone, requests for consolidation at HKIAC doubled to 14 cases (with an 86 percent grant rate), while joinder requests surged from 2 to 13 cases (with a 69 percent grant rate). The 2024 Rules fortified these mechanisms:

• Single Arbitration under Multiple Contracts (Article 29): Allows a claimant to commence a single arbitration across claims arising out of multiple contracts provided a common question of law or fact arises, the rights to relief are in respect of or arise out of the same transaction or a series of related transactions, and the arbitration agreements are compatible.

• Preliminary Powers of HKIAC to Protect the Process (Article 41.4(a) & Article 13.10): Before the tribunal is even constituted, HKIAC is empowered to take any measure necessary to preserve the efficiency or integrity of the arbitration, including in exceptional circumstances revoking the appointment of any arbitrator where the institution declines to proceed with a multi-contract filing or consolidates proceedings.

3. Enhanced Emergency Arbitration Procedure (Schedule 4)

Under Article 23.1 and Schedule 4 of the 2024 Rules, a party requiring urgent interim or conservatory relief that cannot await the constitution of the arbitral tribunal may apply for the appointment of an Emergency Arbitrator simultaneously with, prior to, or following the filing of a Notice of Arbitration.

• Speed of Appointment and Decision: Under Schedule 4, HKIAC aims to appoint an Emergency Arbitrator within 24 hours of receiving the application and deposit, and the Emergency Arbitrator must issue the Emergency Decision within 14 days from the date on which HKIAC transmitted the case file. In practice, HKIAC's 2025 statistics revealed that the average time taken by HKIAC to appoint an Emergency Arbitrator was 15 hours and 11 minutes, and the average time for the Emergency Arbitrator to render a final decision was 12.1 days.

• New Power to Issue Preliminary Interim Orders (Paragraph 10 of Schedule 4): A vital clarification in the 2024 Rules confirms that an Emergency Arbitrator has the express authority to issue "any preliminary or interim order" that they deem necessary pending the rendering of the final Emergency Decision allowing immediate status-quo preservation while the respondent prepares its full reply. Furthermore, Paragraph 13 of Schedule 4 confirms that even if the main arbitral tribunal is constituted before the 14-day period expires, the Emergency Arbitrator retains jurisdiction to render the Emergency Decision if the case file had already been transmitted to the Emergency Arbitrator and the decision is issued within the prescribed 14-day deadline.

4. Early Determination Procedure (Article 43) and Preliminary Issues (Article 13.6)

Under Article 43, an arbitral tribunal has express power, at the request of any party and after consulting all other parties, to decide one or more points of law or fact by way of a summary Early Determination Procedure on the basis that such points of law or fact are: (a) manifestly without merit; (b) manifestly outside the arbitral tribunal's jurisdiction; or (c) even if submitted by another party and assumed to be correct, no award could be rendered in favor of that party. Complementing Article 43, Article 13.6 of the 2024 Rules expressly empowers the tribunal to bifurcate proceedings, conduct the arbitration in sequential stages, and determine the stage at which any preliminary issue shall be resolved.

5. Dual-Track Arbitrator Remuneration and Fee Control (Article 10, Schedules 2 & 3)

HKIAC remains unique among global institutions in offering parties a choice between two methods of remunerating the arbitral tribunal under Article 10.1:

1. Hourly Rates (Schedule 2): The default mechanism unless the parties agree otherwise, where arbitrators are paid according to hourly rates capped by HKIAC, and where Paragraph 5.1 of Schedule 2 of the 2024 Rules now expressly empowers the HKIAC Fees Committee to review and reduce an arbitrator's fees and expenses before final payment.

2. Ad Valorem Based on the Sum in Dispute (Schedule 3): Calculated by reference to the monetary value of the claims and counterclaims, providing predictability for high-value commodities or sovereign-related disputes.

6. Diversity, ESG Environmental Footprints, and Information Security (Articles 9A.2, 13.1, 34.4, & 45A)

Reflecting modern institutional governance, the 2024 Rules embed three contemporary mandates:

• Diversity in Appointments (Article 9A.2): Parties and co-arbitrators are encouraged, and HKIAC is mandated when making institutional appointments, to take into account considerations of diversity alongside availability and qualifications (resulting in female arbitrators representing 36.4 percent of HKIAC's direct appointments in 2025).

• Environmental Impact and Cost Allocation (Articles 13.1 & 34.4(f)): Tribunals must adopt suitable procedures considering information security and environmental impact, and when allocating the costs of the arbitration under Article 34.4, the tribunal may expressly weigh any adverse environmental impact arising out of the parties' conduct during the arbitration (such as insisting on unnecessary long-haul physical travel or voluminous paper bundles where digital alternatives were agreed).

III. Court-Assisted Interim Measures and the Mainland-Hong Kong Arrangement

For international commercial practitioners in London, New York, Singapore, and Beijing, the single greatest strategic differentiator of seating an arbitration in Hong Kong is its dual-vector interim measures architecture: combining aggressive common law injunctive support from the Hong Kong High Court with exclusive statutory access to preservation orders from Mainland Chinese Intermediate People's Courts.

1. Interim Measures in the Hong Kong High Court: Section 45 of Cap. 609

Under Section 45(2) of the Arbitration Ordinance, the Hong Kong Court of First Instance (CFI) may, on the application of any party, grant an interim measure such as a Mareva freezing injunction, an Anton Piller search order, an order for the preservation or inspection of property, or an order to preserve evidence in relation to any arbitral proceedings which have been or are to be commenced in or outside Hong Kong.

Support for Foreign-Seated Arbitrations

Crucially, Hong Kong courts do not restrict their injunctive assistance to Hong Kong-seated arbitrations. Under Section 45(4) and Section 45(5), the CFI will grant an interim measure in aid of a foreign-seated arbitration (for instance, an arbitration seated in Singapore, London, New York, or Zurich) where the arbitral proceedings are capable of giving rise to an arbitral award that may be enforced in Hong Kong, and the interim measure sought belongs to a type or description of interim measure that may be granted in Hong Kong by the Court in relation to arbitral proceedings.

In exercising its discretion under Section 45(7), the Court must have regard to two statutory factors:

1. Whether the interim measure sought is currently the subject of arbitral proceedings; and

2. Whether it is more appropriate for the interim measure sought to be dealt with by the arbitral tribunal (respecting the primacy of the tribunal where it is already constituted and able to act effectively, while stepping in decisively where ex parte urgency, third-party bank compliance, or coercive contempt sanctions are required).

Even more remarkably, in the landmark decision of Company A v Company C [2020] HKCFI 2598, Justice Mimmie Chan held that under Section 60 of the Arbitration Ordinance and Section 21M of the High Court Ordinance, the Hong Kong Court has jurisdiction to grant a standalone interim injunction against a non-party to a foreign-seated arbitration where necessary to prevent the frustration of an eventual arbitral award.

2. The Game-Changer: The Mainland-Hong Kong Interim Measures Arrangement

Historically, under the Civil Procedure Law of the People's Republic of China, Mainland Chinese courts had no statutory authority to grant asset, evidence, or conduct preservation orders (保全措施, baoquan cuoshi) in support of any arbitration seated outside Mainland China. Consequently, if a foreign investor arbitrated in London, Singapore, Paris, or New York against a counterparty whose factories, bank accounts, or equity holdings were located in Shanghai, Shenzhen, or Beijing, the respondent could freely dissipate its Mainland assets while the foreign arbitration was pending.

On 2 April 2019, the Supreme People's Court of the PRC and the Hong Kong Department of Justice signed the landmark Arrangement Concerning Mutual Assistance in Court-Ordered Interim Measures in Aid of Arbitral Proceedings by the Courts of the Mainland and of the Hong Kong Special Administrative Region (which entered into force on 1 October 2019). Even after the recent revision to the PRC Arbitration Law (effective 1 March 2026), Hong Kong remains the ONLY jurisdiction outside Mainland China whose arbitral proceedings enjoy direct access to court-ordered interim preservation measures from Mainland Chinese courts.

Three Strict Qualifying Conditions (Article 2 of the Arrangement)

To qualify as an "arbitral proceeding in Hong Kong" eligible for Mainland court interim relief under Article 2 of the Arrangement, three cumulative legal requirements must be satisfied:

1. Seated in Hong Kong: The arbitration agreement must designate Hong Kong as the legal seat (place) of arbitration.

2. Administered by a Designated Qualified Institution: The arbitration must be institutional (not ad hoc) and administered by one of the arbitral institutions confirmed on the official list jointly approved by the HKDoJ and the Supreme People's Court (which includes HKIAC, the China International Economic and Trade Arbitration Commission [CIETAC] Hong Kong Arbitration Center, the International Court of Arbitration of the International Chamber of Commerce [ICC] – Asia Office, the Hong Kong Maritime Arbitration Group [HKMAG], the South China International Arbitration Center [HK] [SCIAHK], and the eBRAM International Online Dispute Resolution Centre).

3. Contractual Dispute Timing: The application must be made either before the arbitral award is rendered (either before or after the institution has accepted the Notice of Arbitration).

Types of Interim Measures Available in Mainland Courts (Article 1)

A party to a qualified Hong Kong arbitration may apply to the relevant Intermediate People's Court of the place of residence of the respondent or the place where the property or evidence is located in Mainland China for three categories of preservation:

• Property Preservation: Freezing Mainland bank accounts, sealing real estate, attaching industrial equipment, or freezing equity shares in PRC-registered companies.

• Evidence Preservation: Judicially sealing or copying accounting books, servers, customs records, or physical samples located in Mainland China.

• Conduct Preservation: Mandatory or prohibitory injunctions ordering a party to perform or refrain from specific acts (such as restraining the wrongful calling of a performance bond or halting ongoing IP infringement).

Step-by-Step Procedural Workflow under Articles 3 to 5

Practitioners should note the precise statutory workflow for securing a Mainland asset freeze:

• Post-Commencement Applications: Once the arbitral institution (such as HKIAC) has accepted the Notice of Arbitration, the applicant prepares the application for interim measures (addressed to the relevant Mainland Intermediate People's Court and accompanied by Chinese translations of the arbitration agreement, Notice of Arbitration, identity/corporate registration documents, asset leads, and a security/bond undertaking from a PRC insurance company or bank). Under the Arrangement, the institution issues a Letter of Acceptance  and either transmits the application directly to the Mainland court or provides the letter to the applicant's PRC counsel for direct filing at the court's preservation window.

• Pre-Commencement Urgent Applications: Where urgent preservation is sought before the Notice of Arbitration is filed, the applicant files directly with the Mainland Intermediate People's Court; however, if the Mainland court does not receive a Letter of Acceptance from the qualified Hong Kong arbitral institution within 30 days after the interim measure is taken, the Mainland court must automatically lift the preservation order.

Empirical Track Record Through 2026

The empirical data published by HKIAC in February 2026 demonstrates why international counsel routinely select Hong Kong as the seat for China-related and global transactions:

• Between 1 October 2019 and the end of 2025, HKIAC processed 178 applications made to over 40 different Mainland Intermediate People's Courts seeking preservation of assets and evidence totaling RMB 45.3 billion.

• In 2025 alone, HKIAC processed 34 applications across 13 Mainland courts seeking to preserve RMB 10.9 billion (approximately US$1.6 billion).

• Out of 133 reported decisions issued by Mainland courts across the life of the Arrangement, 126 granted the applications upon the provision of security (a nearly 95 percent success rate), successfully freezing assets worth RMB 30.8 billion (approximately US$4.6 billion).

• Crucial Strategic Insight for Global Counsel: Over 50 percent of the applications made in 2025 targeted assets or evidence owned by non-Mainland Chinese entities (such as Cayman Islands, British Virgin Islands, Singaporean, European, or US companies that happened to hold bank accounts, subsidiaries, or receivables inside Mainland China).

IV. Modern Dispute Financing: Third-Party Funding (Part 10A) and Outcome Related Fee Structures (Part 10B)

Historically, Hong Kong inherited the ancient English common law doctrines of maintenance (improperly encouraging litigation in which one has no legitimate interest) and champerty (maintaining an action in return for a share of the proceeds), which operated as both torts and criminal offenses in Hong Kong even after England abolished them in 1967. In Unruh v Seeberger (2007) 10 HKCFAR 31, the Hong Kong Court of Final Appeal left open the question of whether third-party funding of an arbitration conducted in Hong Kong violated champerty.

To ensure Hong Kong remained fully competitive with London, Singapore, and New York in modern dispute finance, the Hong Kong legislature enacted two transformative amendments to the Arbitration Ordinance: Part 10A (Third Party Funding of Arbitration) and Part 10B (Outcome Related Fee Structures for Arbitration).

1. Third-Party Funding (TPF) under Part 10A (Sections 98E–98W)

Fully operative since 1 February 2019, Part 10A of Cap. 609 expressly abolishes the common law offenses and torts of maintenance and champerty in relation to third-party funding of arbitration (and associated court, emergency arbitrator, or mediation proceedings under the Ordinance), whether the arbitration is seated in or outside Hong Kong (for services provided in Hong Kong).

Key statutory rules under Part 10A include:

• Definition of Third-Party Funder (Section 98J): Any person who is a party to a funding agreement for the provision of arbitration funding to a funded party and who does not have an interest recognized by law in the arbitration other than under the funding agreement.

• Historical Exclusion of Practising Lawyers from Part 10A (Section 98O): To preserve legal ethics rules, Section 98O excluded persons who practice law or provide legal services from acting as "third-party funders" under Part 10A a restriction subsequently addressed by the enactment of Part 10B in 2022.

• Mandatory Disclosure of Funding Agreements (Section 98U & Article 44 of the HKIAC Rules): To prevent undisclosed conflicts of interest between arbitrators and commercial litigation funders, Section 98U requires a funded party to give written notice of (a) the fact that a funding agreement has been made and (b) the name of the third-party funder to each other party to the arbitration and to the arbitral tribunal (or institution) upon the commencement of the arbitration (or within 15 days after the funding agreement is made, if entered into later). Similar notice must be given within 15 days if the funding agreement terminates (Section 98V).

• The Code of Practice for Third Party Funding of Arbitration: Issued by the Secretary for Justice under Section 98P, the Code requires funders to maintain at least HK$20 million in capital adequacy, regulate promotional literature, clearly specify in the funding agreement that the funder will not seek to influence the funded party's legal representatives to cede control of the arbitration, and specify whether the funder is liable for adverse costs orders.

2. Outcome Related Fee Structures for Arbitration (ORFS) under Part 10B (Sections 98X–98ZM)

To empower law firms and barristers representing parties in Hong Kong arbitrations to offer flexible, risk-sharing fee arrangements on par with US contingency practices and UK conditional/damages-based agreements, Hong Kong enacted Part 10B of the Arbitration Ordinance alongside the Arbitration (Outcome Related Fee Structures for Arbitration) Rules (Cap. 609D), which came into full operation on 16 December 2022.

Part 10B permits lawyers and clients in arbitrations (and related court or emergency arbitrator proceedings, excluding personal injury claims) to enter into three distinct types of Outcome Related Fee Structures (ORFS):

1. Conditional Fee Agreements (CFAs Section 98ZB): An agreement under which the lawyer agrees with the client to be paid a "success fee" in the event of a successful outcome (as defined by the parties) either on a "no win, no fee" or "no win, low fee" basis. Under Rule 4 of Cap. 609D, the success fee is calculated as an uplift on the benchmark fee (the fee the lawyer would otherwise have charged if no ORFS applied) and is strictly capped at 100 percent of the benchmark fee.

2. Damages-Based Agreements (DBAs Section 98ZC): A pure "no win, no fee" contingency model under which the lawyer receives payment (the "DBA payment") only if the client obtains a "financial benefit" in the matter, calculated directly by reference to the financial benefit obtained (for example, a percentage of the damages awarded or debt recovered, or a percentage of the claim reduction achieved by a respondent). Under Rule 5 of Cap. 609D, the DBA payment is capped at 50 percent of the financial benefit obtained by the client (plus barristers' fees if treated as an expense, unless the barrister is also on a DBA, in which case the combined DBAs cannot exceed 50 percent).

3. Hybrid Damages-Based Agreements (Hybrid DBAs Section 98ZD): The most commercially versatile structure for complex corporate disputes. Under a Hybrid DBA, the lawyer receives (a) reduced or discounted legal fees (typically a percentage of standard hourly rates) during the course of the proceedings regardless of the outcome, plus (b) a DBA payment (capped at 50 percent of the financial benefit) if the client obtains a financial benefit. Under Rule 6 of Cap. 609D, in the event that no financial benefit is obtained, the lawyer may retain at most 50 percent of the irrecoverable costs (the benchmark fee that would have been charged).

Disclosure and Adverse Costs Protection under Part 10B and the 2024 HKIAC Rules

Under Section 98ZQ of the Ordinance and Article 45A of the 2024 HKIAC Rules, a party that has entered into an ORFS agreement must give written notice of the fact that an ORFS agreement has been made and the name of the client to every other party, the tribunal, and HKIAC (without having to disclose the commercial percentage terms of the fee structure). Furthermore, under Section 98ZU, an arbitral tribunal may not order an unsuccessful opposing party to pay the successful party's CFA uplift or DBA payment exceeding the benchmark legal costs, unless the tribunal is satisfied that there are exceptional circumstances justifying such an order.

V. The Judicial Sentinel: Landmark Jurisprudence of the Hong Kong Courts (2023–2026)

What truly cements the reputation of an arbitral seat is how its senior judiciary handles jurisdictional challenges, sovereign claims, multi-tiered clauses, and attempts by losing parties to resist enforcement. overseen by the specialist Arbitration and Construction List of the Court of First Instance (led for over a decade by Madam Justice Mimmie Chan) and the Hong Kong Court of Final Appeal (HKCFA), Hong Kong’s 2023–2026 jurisprudence has established several globally cited common law precedents.

1. The Admissibility vs. Jurisdiction Paradigm: C v D [2023] HKCFA 16

In commercial contracts across energy, infrastructure, and cross-border M&A, parties frequently insert multi-tiered dispute resolution clauses (also known as escalation clauses) requiring them to engage in friendly negotiations for 30 days or mediation before referring the dispute to arbitration. For years, losing respondents sought to set aside arbitral awards under Article 34(2)(a)(iii) of the UNCITRAL Model Law (Section 81 of Cap. 609) by arguing that a claimant’s alleged failure to satisfy a pre-arbitration negotiation condition deprived the arbitral tribunal of jurisdiction, thereby entitling the supervising court to review the condition de novo.

In the landmark judgment of C v D [2023] HKCFA 16 (reported at (2023) 26 HKCFAR 216), the Hong Kong Court of Final Appeal definitively resolved this question for the common law world. Aligning Hong Kong law with leading international arbitral commentary and the English High Court in Republic of Sierra Leone v SL Mining Ltd [2021] EWHC 286 (Comm), the HKCFA held:

• Distinction Between Jurisdiction and Admissibility: There is a fundamental conceptual distinction under the UNCITRAL Model Law between a challenge to the jurisdiction of the tribunal (which asks whether the parties consented to submit the dispute to arbitration at all) and a challenge to the admissibility of the claim (which asks whether a claim that the parties clearly agreed to arbitrate is premature or procedurally barred due to non-compliance with a pre-arbitration step).

• Presumption of Admissibility and Finality of the Tribunal's Ruling: Absent unequivocal contractual language demonstrating that the parties intended non-compliance with a pre-arbitration negotiation step to negate their consent to arbitrate and be subject to de novo judicial review, compliance with a multi-tiered escalation clause is strictly a question of admissibility, not jurisdiction. Consequently, the arbitral tribunal's determination on whether the pre-arbitration condition was satisfied is final, binding, and immune from judicial review under Article 34 of the Model Law.

2. The Interplay of Insolvency and Arbitration: Guy Kwok-Hung Lam v Tor Asia [2023] HKCFA 9 and Simplicissimus [2024] HKCA 477

One of the sharpest doctrinal debates in global commercial law concerns what happens when a creditor presents a winding-up (insolvency) petition against a debtor company on the basis of an unpaid debt, and the underlying contract contains an exclusive jurisdiction clause (EJC) or an arbitration clause. Should the insolvency court automatically stay or dismiss the winding-up petition unless there is an abuse of process (the English approach in Salford Estates (No 2) Ltd v Altomart Ltd [2014] EWCA Civ 1575, which itself was reconsidered by the Privy Council in Sian Participation Corp v Halimeda International Ltd [2024] UKPC 16), or must the debtor demonstrate a bona fide dispute on substantial grounds?

Through a landmark trilogy of cases in 2023 and 2024, the Hong Kong appellate courts forged a balanced, commercially principled doctrine:

1. Guy Kwok-Hung Lam v Tor Asia Credit Master Fund LP [2023] HKCFA 9: In the context of an exclusive jurisdiction clause (EJC) in favor of New York courts, the HKCFA held that in an ordinary case where the underlying dispute of the petition debt is covered by an EJC, the Hong Kong court should ordinarily exercise its discretion to decline jurisdiction and dismiss or stay the bankruptcy/winding-up petition unless there are strong countervailing factors, such as the risk of insolvency affecting third-party creditors or a dispute that borders on the frivolous or an abuse of process.

2. Re Simplicity & Vogue Retailing (HK) Co Ltd [2024] HKCA 299 and Re Shandong Chenming Paper Holdings Ltd [2024] HKCA 352: In twin judgments handed down in April 2024, the Hong Kong Court of Appeal expressly extended the Guy Lam approach to arbitration clauses, confirming that public policy strongly favors holding commercial parties to their contractual bargain to resolve disputes by arbitration (whether the disputed debt is the petition debt itself or a cross-claim/set-off, as confirmed in Shandong Chenming). However, the Court of Appeal emphasized that the Guy Lam approach is not a rigid rule of thumb: where a debtor raises a defense that is wholly frivolous, belatedly fabricated without taking any steps to commence arbitration, or borders on an abuse of process, the Hong Kong Companies Court will intervene and grant a winding-up order.

3. Curtailing Collateral Attacks and Upholding Finality in 2026: G v CNG & SIL [2026] HKCFI 902 and SD v T [2026] HKCFI 4946

The decisions handed down by the Hong Kong Court of First Instance throughout 2026 demonstrate an unyielding commitment to protecting the finality of arbitral awards and punishing opportunistic post-award resistance with indemnity costs:

• G v CNG & SIL [2026] HKCFI 902 (March 2026): After losing a series of partial final awards in a long-running arbitration and failing in applications to remove the presiding arbitrator and set aside the awards in August 2025, the award debtor (CNG) commenced a new arbitration seeking to unwind the underlying contract and nullify the existing awards on the basis of alleged newly discovered fraud and bribery, and asked the Hong Kong Court to stay enforcement of the existing awards. Writing for the Court of First Instance, Justice Mimmie Chan granted an anti-arbitration injunction restraining the new arbitration and ordered CNG to pay indemnity costs with a certificate for three counsel. The Court emphasized that Section 81 of the Arbitration Ordinance (giving effect to Article 34 of the UNCITRAL Model Law) provides the sole and exclusive statutory route for challenging an arbitral award, subject to a strict, non-extendable three-month time limit; allegations of fraud cannot be deployed as an "open sesame" to launch collateral attacks via a second arbitration or reopen disputes that have already been finally determined.

• K v JX [2026] HKCFI 2854 and [2026] HKCFI 4344 (May & July 2026): Clarifying the narrow boundary of the public policy exception at the enforcement stage, the Court of First Instance addressed an application to set aside an enforcement order of a Mainland arbitral award where evidence of lack of authority, collusion, and bribery of witnesses surfaced only after the arbitral award was rendered and had never been presented to or determined by the arbitral tribunal. While reiterating that the Hong Kong Court never permits a party to re-argue the merits under the guise of public policy where the issue was already put to and rejected by the tribunal, the Court held that where credible post-award evidence of serious corruption or bribery of witnesses emerges for the first time at the enforcement stage, the enforcing court will examine the evidence and refuse enforcement if enforcing the award would violate Hong Kong's fundamental notions of morality and justice.

• SD v T [2026] HKCFI 4946 and O v S [2026] HKCFI 4910 (August 2026): In SD v T, the Court reaffirmed the low prima facie threshold under Section 20 of the Arbitration Ordinance (Article 8 of the Model Law): so long as there is a prima facie or plainly arguable case that a valid arbitration agreement exists and was incorporated into a subcontract, the Court must stay litigation and refer the parties to the arbitral tribunal to determine its own jurisdiction under the principle of kompetenz-kompetenz. Simultaneously, in O v S, the Court dismissed an opportunistic attempt to set aside a partial award for alleged apparent bias merely because the presiding arbitrator had previously sat in an unrelated arbitration where the same factual witness had testified.

VI. The Cross-Border Enforcement Ecosystem: New York Convention and the Mainland-Hong Kong Enforcement Arrangements

For an international arbitration practitioner, an arbitral award is only as valuable as the speed and certainty with which it can be converted into cash or assets. In 2026, Hong Kong awards enjoy a three-track global enforcement architecture under Part 10 of the Arbitration Ordinance (Sections 84 to 98D):

1. Global Enforcement under the 1958 New York Convention

Through China's sovereignty extension upon the 1997 handover, the 1958 United Nations Convention on the Recognition and Enforcement of Foreign Arbitral Awards (the New York Convention) applies to Hong Kong. Consequently:

• Hong Kong Awards Abroad: Arbitral awards rendered in Hong Kong are directly enforceable across more than 172 New York Convention Contracting States worldwide including the United Kingdom, the United States, Singapore, France, Germany, Japan, Australia, and India.

• Foreign Convention Awards in Hong Kong (Sections 87–89): Awards made in any New York Convention state are summarily enforceable in the Hong Kong Court of First Instance upon an ex parte origin application supported by the authenticated original award (or certified copy) and original arbitration agreement, shifting the burden exclusively onto the award debtor within a strict 14-day window to establish one of the exhaustive narrow defenses listed in Section 89 (mirroring Article V of the New York Convention). Moreover, even for awards rendered in non-Convention states and outside Mainland China or Macao, Section 84 permits summary enforcement with the leave of the Court under the same pro-enforcement philosophy.

2. Mutual Enforcement with Mainland China (Including the Supplemental Arrangement)

Because Hong Kong and Mainland China are part of one sovereign state, the New York Convention does not govern enforcement between them. Instead, enforcement is governed by the Arrangement Concerning Mutual Enforcement of Arbitral Awards Between the Mainland and the HKSAR (1999), as significantly modernized by the Supplemental Arrangement Concerning Mutual Enforcement of Arbitral Awards (signed in November 2020 and fully operative since May 2021):

• Simultaneous Enforcement Applications in Both Jurisdictions: Removing a problematic historical restriction, Article 3 of the Supplemental Arrangement allows a prevailing party in a Hong Kong or Mainland arbitration to apply for enforcement of the arbitral award in the courts of both Mainland China and Hong Kong simultaneously (provided that the total amount recovered across both courts does not exceed the total amount awarded).

• Broadened Scope of Enforceable Mainland Awards: Under Section 92 of the Arbitration Ordinance as amended by the Supplemental Arrangement, any arbitral award made pursuant to the PRC Arbitration Law by a Mainland arbitral authority not limited to a closed historical list of institutions is enforceable in Hong Kong.

• Post-Award Interim Measures Pending Enforcement: Under Article 4 of the Supplemental Arrangement and Section 45 of Cap. 609, both Mainland and Hong Kong courts are expressly empowered to impose property preservation and freezing measures before or after accepting an application to enforce an arbitral award.

VII. Practical Drafting and Strategic Checklist for Counsel in 2026

When structuring cross-border commercial contracts involving Asian, European, UK, US, or Mainland Chinese counterparties in 2026, in-house counsel and transactional lawyers should implement five best-practice drafting protocols:

1. Adopt the 2024 HKIAC Model Clause with an Express Governing Law for the Arbitration Agreement:

To prevent costly satellite litigation over which law governs the validity and scope of the arbitration clause itself, always include the optional fourth limb of the HKIAC Model Clause:

"Any dispute, controversy, difference or claim arising out of or relating to this contract, including the existence, validity, interpretation, performance, breach or termination thereof or any dispute regarding non-contractual obligations arising out of or relating to it shall be referred to and finally resolved by arbitration administered by the Hong Kong International Arbitration Centre (HKIAC) under the HKIAC Administered Arbitration Rules in force when the Notice of Arbitration is submitted. The law of this arbitration clause shall be Hong Kong law. The seat of arbitration shall be Hong Kong. The number of arbitrators shall be [one or three]. The arbitration proceedings shall be conducted in [English / Chinese]."

2. Designate Institutional Administration (Never Pure Ad Hoc) if Mainland Assets May Be Involved:

Remember that under Article 2 of the Mainland-Hong Kong Interim Measures Arrangement, ad hoc arbitrations seated in Hong Kong do not qualify for court-ordered asset or evidence preservation in Mainland Chinese courts. If your counterparty whether a PRC state-owned enterprise, a private Shenzhen technology firm, or a Cayman/BVI holding company holds bank accounts, real estate, inventory, or joint venture equity in Mainland China, you must specify institutional administration by HKIAC (or another designated qualified institution) seated in Hong Kong.

3. Select the Arbitrator Fee Basis Expressly (Schedule 2 vs. Schedule 3):

If cost predictability in a high-value dispute is paramount, specify in the arbitration agreement (or agree within 30 days of the Answer to the Notice of Arbitration) whether the tribunal's fees shall be calculated by hourly rates (Schedule 2) or ad valorem by reference to the sum in dispute (Schedule 3).

4. Ensure Compatibility Across Multi-Contract Transaction Suites:

When drafting complex M&A, private equity, or construction suites (such as a Share Purchase Agreement, Shareholders' Agreement, and Guarantee), ensure that the seat, institutional rules, number of arbitrators, and appointment mechanisms across all agreements are strictly identical so that claims can be brought seamlessly in a single arbitration under Article 29 or consolidated under Article 28 of the 2024 HKIAC Rules.

5. Leverage Part 10B Hybrid DBAs and Part 10A Third-Party Funding Early:

Before commencing or defending a capital-intensive arbitration in Hong Kong, evaluate with Hong Kong counsel whether a Hybrid Damages-Based Agreement (Hybrid DBA) under Part 10B or non-recourse Third-Party Funding under Part 10A can optimize corporate cash flow, and ensure mandatory statutory disclosure notices under Sections 98U or 98ZQ are served promptly upon commencement to insulate the proceeding from procedural challenges.

Conclusion: The Enduring Authority of the Hong Kong Arbitral Seat

As this comprehensive analysis illustrates, the Hong Kong arbitration matrix in 2026 represents one of the most sophisticated, commercially responsive, and judicially fortified dispute resolution systems in the world. Anchored in the UNCITRAL Model Law framework of the Arbitration Ordinance (Cap. 609) and continuously refined as seen in the September–October 2026 Department of Justice reform consultation Hong Kong seamlessly unites the analytical rigor and predictability of English-tradition common law adjudication with unparalleled institutional connectivity to the world's second-largest economy.

Supported by the record-setting administration of the HKIAC under its 2024 Rules, the unmatched cross-border preservation power of the Mainland-Hong Kong Interim Measures Arrangement, the innovative dispute financing options of Part 10A and Part 10B, and the fiercely pro-arbitration jurisprudence of the Hong Kong Court of First Instance, Court of Appeal, and Court of Final Appeal, Hong Kong stands in 2026 as an indispensable global seat for resolving the most complex cross-border commercial disputes of the twenty-first century.
