Drafting an effective arbitration clause for Hong Kong commercial contracts

What an arbitration clause in a Hong Kong commercial contract must specify

When drafting an arbitration clause Hong Kong commercial contract, the primary statutory source is the Arbitration Ordinance (Cap. 609). Section 19 gives effect to Option I of Article 7 of the UNCITRAL Model Law and defines an arbitration agreement as an agreement by the parties to submit to arbitration all or certain disputes which have arisen or which may arise between them in respect of a defined legal relationship, whether contractual or not. The agreement must be in writing, meaning its content is recorded in any form. An electronic communication satisfies the requirement if the information in it is accessible for subsequent reference.

The only statutory validity requirements are an agreement to arbitrate disputes from a defined legal relationship and a written record of that agreement. The seat, governing law, administering institution, number of arbitrators and language are not statutory validity requirements. Section 23(3) provides that the HKIAC decides whether there are one or three arbitrators where the parties have not agreed. Sections 13 and 24 make the HKIAC the default appointing authority. Section 48 gives effect to Model Law Article 20, under which the tribunal determines the place failing agreement. Section 50 gives effect to Article 22, under which the tribunal determines the language.

Specifying these elements remains advisable. An unspecified seat leaves the applicable procedural law undetermined until the tribunal fixes it, because section 5(1) applies the Ordinance where the place of arbitration is in Hong Kong and only a listed subset applies to foreign-seated arbitrations under section 5(2). This is a practical risk, not a validity defect. Section 20 gives effect to Model Law Article 8 and contains the operative test: a court must refer the parties to arbitration unless it finds the agreement null and void, inoperative or incapable of being performed. Vagueness that makes a clause inoperable is what defeats it, not the absence of a seat, an institution, a number or a language.

Hong Kong International Arbitration Centre arbitration rules

The Hong Kong International Arbitration Centre, established in 1985 as a Hong Kong company limited by guarantee, administers arbitrations under its own rules. Section 13(2) gives the HKIAC the functions of the court or other authority under Model Law Article 11(3) and (4), given effect by section 24. Under section 24(3) the HKIAC must make the necessary appointment on request where an agreed appointment procedure fails or a party does not appoint within 30 days of request. Under section 24(5) an HKIAC appointment has effect as if made with the agreement of all parties. Section 32(1) covers appointment of a mediator and section 30 appointment of an umpire.

The HKIAC publishes its own model clause. The typical formulation reads: "Any dispute arising out of or in connection with this contract shall be referred to and finally resolved by arbitration administered by the Hong Kong International Arbitration Centre under the HKIAC Administered Arbitration Rules in force when the Notice of Arbitration is submitted." The clause should specify the seat of arbitration as Hong Kong, the number of arbitrators and the language of proceedings. The HKIAC rules provide for emergency arbitrator procedures and expedited procedures for claims below stated thresholds.

UNCITRAL Model Law Hong Kong Arbitration Ordinance

Section 4 of Cap. 609 gives the provisions of the UNCITRAL Model Law expressly stated in the Ordinance the force of law in Hong Kong. The Ordinance contains no division between domestic and international arbitration: section 5 applies it to any arbitration seated in Hong Kong. Section 3 states the object as facilitating the fair and speedy resolution of disputes by arbitration without unnecessary expense, on the principles that the parties should be free to agree how their dispute is resolved, subject to safeguards necessary in the public interest, and that the court should interfere only as the Ordinance expressly provides.

Schedule 2 contains seven optional provisions covering a sole arbitrator, consolidation, a preliminary question of law for the court, challenge for serious irregularity, appeal on a question of law, leave to appeal, and supplementary provisions. Section 99 lets an arbitration agreement opt in to any of them expressly. Section 100 applied them automatically to agreements providing for domestic arbitration entered into before commencement or within six years after it, meaning on or before 31 May 2017, so express opt-in under section 99 is now the live route.

Enforcing Hong Kong arbitral awards in Mainland China

The New York Convention was done at New York on 10 June 1958, and section 2(1) of Cap. 609 defines it by that date. Article V sets out the grounds on which recognition and enforcement may be refused, with Article V(2) adding arbitrability and public policy. China acceded on 22 January 1987, in force 22 April 1987. On resumption of sovereignty on 1 July 1997, China extended the Convention's territorial application to Hong Kong, subject to the statement China made on accession. The constitutional mechanism is Article 153 of the Basic Law.

Section 2(1) defines a Convention award as one made in a State or territory other than China or any part of China. Mainland and Macao awards therefore fall outside the Convention route and use the separate Arrangements. The Arrangement Concerning Mutual Enforcement of Arbitral Awards between the Mainland and the HKSAR was signed on 21 June 1999 and took effect on 1 February 2000, under Article 95 of the Basic Law. The Supplemental Arrangement was signed in Shenzhen on 27 November 2020. It confirmed that enforcement procedures include recognition; changed the scope from a list of institutions to the seat of arbitration, covering awards rendered pursuant to the Arbitration Ordinance; allowed an applicant to apply to the courts of both places where the respondent is domiciled or has property in both, capped at the award amount and with information sharing between courts; and allowed a court to impose preservation or mandatory measures before or after accepting an enforcement application. Articles 1 and 4 of the Supplemental Arrangement took effect on 27 November 2020. Articles 2 and 3 took effect on 19 May 2021, following the Arbitration (Amendment) Ordinance 2021, Ordinance 1 of 2021, which repealed sections 93 and 97 of Cap. 609.

Seat of arbitration clause Hong Kong

The seat of arbitration determines the procedural law applicable to the arbitration and the courts that have supervisory jurisdiction. For a Hong Kong-seated arbitration, the Arbitration Ordinance (Cap. 609) applies under section 5(1). The seat is not the physical hearing location; hearings may take place elsewhere while the seat remains Hong Kong. Model Law Article 20, given effect by section 48, provides that the parties may agree on the place of arbitration. Failing agreement, the tribunal determines the place having regard to the circumstances.

A typical seat clause reads: "The seat of arbitration shall be Hong Kong." This ensures that the Hong Kong courts have jurisdiction to entertain applications under sections 20 (referral to arbitration), 24 (appointment of arbitrators), 34 (challenge of arbitrators), 48 (place of arbitration), 81 (setting aside an award) and 84 (recognition and enforcement). Without a specified seat, the tribunal determines the place under section 48, and the applicable procedural law remains uncertain until that determination.

Interim measures from Mainland courts

The Arrangement Concerning Mutual Assistance in Court-ordered Interim Measures in Aid of Arbitral Proceedings by the Courts of the Mainland and of the HKSAR was signed in Hong Kong on 2 April 2019 and came into operation on 1 October 2019. Article 2(1) requires the arbitral proceedings to be seated in Hong Kong and administered by a qualifying institution. A qualifying institution is an arbitral institution established in Hong Kong or headquartered here with its principal place of management here; a dispute resolution institution or permanent office set up in Hong Kong by an international intergovernmental organisation of which China is a member; or a dispute resolution institution or permanent office set up in Hong Kong by another arbitral institution.

The Department of Justice publishes the qualifying list. As at 27 January 2026 it contained nine institutions and permanent offices, including the Hong Kong International Arbitration Centre, the Hong Kong Maritime Arbitration Group, the South China International Arbitration Center (HK), eBRAM International Online Dispute Resolution Centre, the Shanghai International Arbitration (Hong Kong) Center, the Asia Pacific International Arbitration Chamber Hong Kong Arbitration Center, the AALCO Hong Kong Regional Arbitration Centre, the CIETAC Hong Kong Arbitration Center, and the Asia Office of the Secretariat of the ICC International Court of Arbitration. Designations run for two years from 2 April 2025 and expire on 1 April 2027, subject to re-application. The list changes, so it should be checked at the time of any filing.

The Arrangement allows a party to a Hong Kong-seated arbitration administered by a qualifying institution to apply to the Mainland court for preservation measures, including asset preservation, evidence preservation and conduct preservation. This is the only route by which a Hong Kong seat gives access to Mainland interim measures before the award is rendered. It is available only where the administering institution appears on the current qualifying list.

Governing law and the arbitration agreement

The governing law of the contract and the law governing the arbitration agreement may differ. Under Model Law Article 16(1), given effect in the Ordinance, the arbitral tribunal may rule on its own jurisdiction, including any objections with respect to the existence or validity of the arbitration agreement. The governing law of the arbitration agreement determines matters such as the capacity of the parties, the scope of disputes submitted to arbitration, and the formal validity of the agreement.

A typical clause separates the two: "This contract shall be governed by the laws of Hong Kong. The arbitration agreement in this clause shall be governed by the laws of Hong Kong." Specifying the governing law of the arbitration agreement avoids disputes about which law governs its validity, particularly where the contract is governed by another system of law.

Number of arbitrators and language of proceedings

The parties should specify the number of arbitrators in the arbitration clause. Section 23(3) provides that where the parties have not agreed on the number of arbitrators, the HKIAC decides whether there are one or three arbitrators. A three-arbitrator tribunal is appropriate for high-value or complex disputes; a sole arbitrator is more cost-effective for smaller claims.

The language of proceedings should be specified to avoid procedural disputes. Section 50 gives effect to Model Law Article 22, under which the tribunal determines the language failing agreement. A typical clause reads: "The language of the arbitration shall be English." Or the clause may specify Chinese or both languages. The tribunal may order translations of documents if the parties have not agreed.

Enforcement of award and the New York Convention

A Hong Kong arbitral award is enforceable in Hong Kong under the Arbitration Ordinance as an award made under the Ordinance. For enforcement outside Hong Kong, the New York Convention applies where the enforcement state is a party to the Convention. As at 30 August 2026, there were 172 States party to the Convention. Article V sets out the grounds on which recognition and enforcement may be refused: incapacity of the parties, invalidity of the arbitration agreement, lack of proper notice or inability to present the case, award beyond the scope of submission, irregular composition of the tribunal or procedure, award not yet binding or set aside, or the subject matter not being arbitrable or enforcement contrary to public policy.

For enforcement in Mainland China, the Arrangement Concerning Mutual Enforcement of Arbitral Awards applies rather than the New York Convention, because Mainland awards fall outside the Convention route under section 2(1). The Supplemental Arrangement broadened the scope from a list of institutions to the seat of arbitration, making enforcement available for any award rendered pursuant to the Arbitration Ordinance regardless of the administering institution.

Scheme of arrangement as alternative

While arbitration resolves disputes between contracting parties, a scheme of arrangement under Part 13, Division 2 of the Companies Ordinance (Cap. 622), sections 668 to 677, provides an alternative for debt restructuring where the company faces financial difficulty. Section 670 lets the court order a meeting of creditors or members. Section 671 requires an explanatory statement. Section 673 provides for court sanction; once sanctioned the scheme binds every member of the class. Section 674(1) requires a majority in number representing at least 75% in value of the creditors present and voting. A Hong Kong scheme carries no statutory moratorium and no cross-class cram down. The Government confirmed that more than 40 debt restructuring schemes were sanctioned in the five years to 2026.

An arbitration clause in a commercial contract does not prevent a company from using a scheme of arrangement, because the scheme binds a class of creditors by court order rather than by individual agreement. The arbitration agreement remains enforceable for disputes between the company and creditors who are not bound by the scheme.
