How to approach enforcing an arbitral award from Mainland China in Hong Kong

An award creditor with a favourable Mainland arbitral award faces a deceptively narrow window. The assets that matter – bank accounts, receivables, equity stakes in Hong Kong vehicles – sit across a boundary that has its own legal architecture. The question is not whether enforcement is available. It is which mechanism applies, in which sequence, and whether a procedural misstep has already closed a door.

Enforcing a Mainland Chinese arbitral award in Hong Kong runs through a dedicated mutual-recognition regime – the Arrangement Concerning Mutual Enforcement of Arbitral Awards between the Mainland and the Hong Kong Special Administrative Region (the 1999 Arrangement), as supplemented and amended – not through the New York Convention. The governing procedure requires an application to the Court of First Instance. Since a 2021 amendment to the regime, simultaneous enforcement applications on both sides of the boundary are permitted. The creditor who understands this sequence before filing holds a structurally stronger position than one who discovers it mid-process.

This guide sets out the decision the reader faces, the procedural sequence step by step, the gate at each stage, and the most common mistake our desk sees in cross-border enforcement files.

Which mechanism governs – and why the New York Convention does not apply?

The New York Convention on the Recognition and Enforcement of Foreign Arbitral Awards does not apply to awards made on the Mainland when the seat of enforcement is Hong Kong. Both are parts of the People's Republic of China, and the Convention operates between contracting states as distinct territorial units. Enforcement across the Mainland–Hong Kong boundary therefore runs under a bilateral arrangement, not the Convention.

The operative instrument is the 1999 Arrangement and its Supplemental Arrangement, which took effect from 2020. The Supplemental Arrangement modernised the regime in important respects: it aligned the grounds for refusal more closely with international standards, clarified the procedure for applying in Hong Kong, and – critically – permitted simultaneous enforcement applications. Before that change, a creditor had to elect a single jurisdiction. That election often produced delay and tactical asymmetry.

For in-house counsel reviewing an award, the first discipline is therefore to confirm: where was the arbitration seated? An award made by a Mainland institution with a Mainland seat runs under the Arrangement. An award made in a Hong Kong-seated arbitration – even one administered by a Mainland institution – runs under a different track and may engage the New York Convention for enforcement in third countries. These are separate legal pathways. Conflating them is the single most common orientation error on cross-border enforcement files.

Our desk regularly reviews mandates where external counsel in the client's home jurisdiction has assumed the New York Convention route applies to a Mainland award. The procedural assumptions built on that error can compromise the application before it is filed.

What are the available options before you file?

An award creditor is not obliged to begin enforcement immediately. Three options sit on the table after the award is issued, and the choice between them shapes the timeline and the asset-preservation risk.

First, the creditor can apply at once for recognition and enforcement (recognition being the Hong Kong court's confirmation that the award is valid; enforcement being the step that gives it coercive effect against assets). These two steps are typically combined in a single application.

Second, the creditor can pursue interim measures on the Mainland while the enforcement application proceeds in Hong Kong. Since 1 October 2019, a separate regime – 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 – has allowed parties to Hong Kong-seated arbitrations to apply to Mainland courts for interim measures. This operates in parallel, not as a substitute for enforcement.

Third, the creditor can engage the debtor on a negotiated outcome, using the award as leverage. Where assets are mobile – as they often are in trading structures – delay on formal enforcement can mean dissipation. Our experience is that a creditor who has mapped the enforcement route in advance, and who can demonstrate that the first application is ready to file, is in a materially stronger negotiating position.

The choice between these options depends on asset location, asset mobility, and whether there is a risk that the debtor will apply to set aside the award on the Mainland. A setting-aside application on the Mainland does not automatically stay enforcement in Hong Kong, but it introduces procedural complexity that the creditor should anticipate.

What is the step-by-step enforcement sequence in Hong Kong?

Enforcement of a Mainland arbitral award in Hong Kong follows a defined procedural sequence before the Court of First Instance. Each step has a gate – a condition that must be satisfied before the next step opens.

Step 1 – Confirm the award is enforceable under the Arrangement. Not every Mainland arbitral award falls within the scope of the 1999 Arrangement and its Supplemental Arrangement. The award must have been made by a Mainland arbitral authority. It must be a final award, not a procedural order or interim ruling. It must not fall within the categories that the regime excludes from its scope. The creditor's first task is to verify these conditions before taking any procedural step in Hong Kong.

Step 2 – Obtain a certified copy of the award and the arbitration agreement. The Hong Kong application requires the production of a certified copy of the original award and the underlying arbitration agreement (or a certified copy thereof). Where the award or agreement is in Mandarin, a certified English translation is required. The quality of the translation and the form of the certification matter. Applications have stalled at this gate because the certification did not meet the Court's requirements. Parties should verify the current requirements with counsel before commissioning the translation.

Step 3 – File the enforcement application with the Court of First Instance. The application is made by way of originating summons. It is made ex parte in the first instance – that is, without prior notice to the debtor. The application must exhibit the certified documents, set out the basis on which the Arrangement applies, and identify the relief sought. The Court's role at this stage is to satisfy itself that the formal requirements are met and that no ground for refusal is immediately apparent.

Step 4 – Serve the order on the debtor. Once the Court grants leave to enforce, the order must be served on the debtor. Service on a debtor based in the Mainland requires compliance with the applicable cross-border service regime. This is a step that carries its own timeline and, if handled incorrectly, can found a later challenge by the debtor. The debtor has a defined period after service to apply to set aside the leave order.

Step 5 – Respond to any setting-aside application by the debtor. The debtor may apply to set aside the order on grounds that correspond broadly to those in Article V of the New York Convention – incapacity, invalid agreement, lack of due notice, award outside the scope of the submission, irregular tribunal composition, non-binding or set-aside award on the Mainland, or public policy. If no application to set aside is made within the permitted period, the award creditor can move immediately to enforcement action against assets.

Step 6 – Execute against assets. With the award recognised and the debtor having failed or declined to set aside the order, the creditor holds a Hong Kong judgment debt. Execution routes available against Hong Kong assets include garnishee proceedings (for receivables and bank accounts), charging orders (for Hong Kong-sited securities or property interests), and appointment of a receiver. The selection of execution method depends on the nature, location and traceability of the debtor's Hong Kong assets.

The sequence above describes the standard position. Your matter turns on the documents, the jurisdictions actually engaged, and the order of steps – which is where the route is won or lost.

What are the grounds on which enforcement can be refused – and what can a creditor do about them?

The Hong Kong court may refuse to recognise and enforce a Mainland award on a defined set of grounds. Understanding these grounds in advance allows the creditor to anticipate and, where possible, address them before the debtor raises them.

The grounds broadly mirror international standards. They include: one of the parties was under an incapacity; the arbitration agreement is invalid under the law governing it; the award debtor was not given proper notice of the appointment of an arbitrator or of the proceedings, or was otherwise unable to present its case; the award deals with a dispute not falling within or not contemplated by the submission to arbitration; the composition of the arbitral authority or the arbitral procedure was not in accordance with the agreement of the parties or the applicable law; the award has not yet become binding on the parties, or has been set aside or suspended by a competent authority; the subject matter of the dispute is not capable of settlement by arbitration under Hong Kong law; or enforcement would be contrary to public policy.

Of these, the public policy ground attracts the most attention in cross-border files. Hong Kong courts have consistently interpreted public policy narrowly in the arbitration context. A mere error of law or fact in the award is not public policy. The standard is whether enforcement would be manifestly contrary to the fundamental conceptions of morality and justice as understood in Hong Kong. That is a high threshold, and it is rarely met in commercial disputes between sophisticated parties.

Where a creditor anticipates a procedural-due-process challenge – for example, because service of the arbitration notice on the Mainland debtor was irregular – it is better to confront this in the filing documents than to wait for the debtor to raise it. Courts are more receptive to a creditor who has addressed a potential objection directly than to one who has omitted it.

How does simultaneous enforcement on both sides of the boundary work?

Since the 2021 amendment to the mutual enforcement regime, a creditor holding a Mainland award may file enforcement applications in Hong Kong and on the Mainland at the same time. This is a material procedural advantage over the pre-amendment position, under which a single-jurisdiction election was required.

The practical significance is asset coverage. A debtor with assets on both sides of the boundary – a common structure for trading and investment groups with Greater China operations – can no longer protect one pool of assets simply by resisting enforcement in the other jurisdiction. The creditor can move simultaneously in both forums, subject to the condition that total recovery does not exceed the amount of the award.

Coordinating simultaneous applications requires counsel who understand both the Hong Kong procedure before the Court of First Instance and the Mainland enforcement process before the people's courts. The documents, the certification requirements, and the procedural timelines differ. Where a creditor has engaged a Hong Kong cross-border desk that works alongside Mainland-qualified allied counsel, the coordination of simultaneous filings is materially more reliable than managing two separate instructed sets without a common coordinator.

An Asian trading group facing a substantial claim against a Mainland counterparty came to us in late 2025 after an initial enforcement filing in Hong Kong had stalled at the service step. We re-assessed the asset position, confirmed that significant assets were also held through a Hong Kong subsidiary, and coordinated a simultaneous filing that covered both pools within a single procedural cycle. The debtor's setting-aside application was resisted on the public policy point; it did not succeed.

What is the most common mistake, and how does the sequence avoid it?

The most common mistake is sequencing errors that arise from treating a Mainland award as equivalent to a New York Convention award. This produces two types of errors in practice.

The first is a wrong-mechanism error. Counsel in the creditor's home jurisdiction files a New York Convention enforcement application before a Hong Kong court. The court identifies that the Arrangement, not the Convention, governs. The application must be withdrawn and refiled under the correct mechanism. Time has been lost, and the debtor has been alerted to the creditor's intentions before the ex parte stage is properly managed.

The second is a document-certification error. Parties who are familiar with the New York Convention's certification requirements in other jurisdictions sometimes apply those assumptions to Hong Kong proceedings under the Arrangement. The Hong Kong requirements for certified copies and certified translations are specific. A mismatch between the form of certification obtained and the form the Court requires can delay the application by weeks.

The sequence set out in this guide is specifically designed to address both errors. The preliminary step – confirming that the Arrangement applies and that the award is within scope – is the gate that prevents both problems. It is not a formality. It is the analysis that determines which document set to commission, which court procedure to invoke, and how to frame the application.

If an earlier filing, structure, or enforcement attempt produced an adverse or stalled result, a second read can identify the strategic error and the routes still open. Write to us at info@lockhartyip.com to discuss your position.

Decision checklist before filing

The following checklist is intended for in-house counsel and principals preparing for an enforcement application. It is not a substitute for specific legal advice on your file.

• Award scope: Is the award made by a Mainland arbitral authority with a Mainland seat? Confirm it is a final award, not an interim ruling or procedural order.
• Arrangement scope: Does the award fall within the subject-matter scope of the 1999 Arrangement and its Supplemental Arrangement? Are any exclusions relevant?
• Documents: Do you hold a certified copy of the award and the arbitration agreement? Are certified English translations ready, in the form the Court of First Instance requires?
• Asset mapping: Where are the debtor's assets? Are they in Hong Kong, on the Mainland, or both? What execution method is appropriate for each asset class?
• Simultaneous filing: Is there a case for simultaneous enforcement applications in Hong Kong and on the Mainland? Has the coordination of both processes been addressed?
• Setting-aside risk: Has the debtor applied – or indicated it will apply – to set aside the award on the Mainland? Has the effect of any such application on Hong Kong enforcement been assessed?
• Refusal grounds: Can any of the grounds for refusing enforcement be anticipated on your facts? Has each been addressed in the filing documents?
• Interim measures: If assets are at risk of dissipation, is an application for interim measures available and proportionate to the risk?
• Timing: Have the applicable limitation periods for bringing an enforcement application been verified? This is a point to confirm with counsel on your specific facts.

This checklist reflects the standard position under the Arrangement. Parties should verify the current procedural requirements before acting, as the regime and the Court's current practice can develop.
