How to approach recognising a court judgment from Mainland China in Hong Kong

A judgment creditor holding a Mainland court decision faces a specific, time-sensitive question: how does that decision become enforceable against assets in Hong Kong? The answer changed materially when the Mainland Judgments in Civil and Commercial Matters (Reciprocal Enforcement) Ordinance (Cap. 645) came into force on 29 January 2024. The new regime replaces the narrower 2008 arrangement and removes the old requirement that the parties had exclusively agreed on Mainland jurisdiction. The path is clearer than it was. It is not, however, automatic.

Recognising a court judgment from Mainland China in Hong Kong is governed by Cap. 645, which provides for registration of an effective Mainland judgment with the Court of First Instance; once registered, the judgment carries the same force as a Hong Kong judgment and may be enforced against assets here. The regime has applied to judgments made on or after 29 January 2024.

This guide sets out the decision the judgment creditor actually faces, the sequence of steps in order, the gates at each stage, the single most common mistake practitioners see, and a short checklist for in-house counsel preparing to act.

What decision does the judgment creditor face first?

Before any application is filed, the creditor must make a threshold choice. Cap. 645 creates a registration route – but not every Mainland civil or commercial judgment qualifies, and not every asset situation calls for a Hong Kong enforcement step.

The first question is jurisdictional eligibility. Does the judgment fall within the scope of Cap. 645? Certain categories are expressly excluded: insolvency-related orders, certain intellectual-property determinations, certain arbitration-related orders, succession matters, and matrimonial proceedings. If the judgment sits in an excluded category, Cap. 645 does not apply, and the creditor must consider alternative routes – including common-law proceedings or, where an arbitral award underlies the dispute, the separate mutual-enforcement arrangement for arbitral awards.

The second question concerns the asset map. If the debtor's Hong Kong-based assets are minimal or easily concealed, registration alone may not achieve recovery. The timing of registration relative to dissipation risk matters considerably. In our cross-border practice, we regularly see creditors who treat the legal step as the endpoint. The endpoint is the asset. The legal step is the means of reaching it.

Where both questions are answered favourably – the judgment qualifies and there are real assets to pursue – the registration route under Cap. 645 is the logical starting point. Where there is doubt on eligibility, that doubt must be resolved before the application is filed, not after.

Does the judgment itself qualify under Cap. 645?

Cap. 645 applies to Mainland civil and commercial judgments that are "effective" – meaning they have taken effect under Mainland procedure – and that were made on or after 29 January 2024. This date operates as a hard cut-off: judgments made before that date are not registrable under the new ordinance, though they may still be the subject of a common-law action on the judgment debt.

The old exclusive-jurisdiction requirement has been removed. Under Cap. 645, the Mainland court no longer needed to have been chosen as the exclusive forum by written agreement. Instead, the ordinance applies a connection-based test to establish that the Mainland court had proper jurisdiction over the matter. That broadening of scope is significant for commercial disputes where no choice-of-court clause existed or where jurisdiction was founded on the defendant's presence or asset location.

Monetary and non-monetary judgments both fall within scope, subject to the exclusion list. For most commercial creditors, the relevant judgment will be a monetary award for debt, damages, or costs. Non-monetary relief – injunctions, specific performance – is also registrable in principle, though enforcement of such orders raises practical questions that go beyond the registration step itself.

One point that catches foreign principals: the judgment must be "effective" in the Mainland sense, not merely "final" in the sense a common-law court would use. Mainland civil procedure recognises a judgment as effective when the appeal period has expired without an appeal being lodged, or when the appellate process has concluded. The creditor must be in a position to demonstrate this to the Hong Kong court at the registration stage.

What is the step-by-step sequence for registration?

The registration process runs through the Court of First Instance of the High Court of Hong Kong. The sequence, in order, is as follows.

Step 1 – Obtain certified copies and translations. The applicant must produce a certified copy of the Mainland judgment together with a certificate issued by the Mainland court. Both documents must be accompanied by a certified translation into English. The translation certification requirements are formal; a translation that is accurate but uncertified will not satisfy the court's procedural rules. Allow sufficient lead time to obtain both the Mainland court certificate and a properly certified translation before the Hong Kong application is prepared.

Step 2 – Verify the judgment has not been satisfied or set aside. The Cap. 645 regime contains grounds on which registration will be refused or may be set aside after registration. If the judgment has been satisfied in whole or in part, or has been set aside or suspended by a Mainland court, the Hong Kong court cannot register it. The creditor's legal team must confirm the current status of the judgment before filing, ideally with up-to-date evidence from the Mainland court record.

Step 3 – File the ex parte originating application. Registration under Cap. 645 is initially applied for without notice to the judgment debtor. The application is made by originating application in the Court of First Instance. The evidence in support must address the eligibility conditions: the nature of the judgment, its effective status, the jurisdictional basis, and the absence of the exclusion categories. The court must be satisfied on all of these points before it grants registration.

Step 4 – The court grants registration; notice is served on the debtor. Once the court makes the registration order, the judgment debtor must be served with notice. The debtor then has a defined period in which to apply to set aside the registration. During that window, enforcement steps are ordinarily stayed. The creditor should not assume that registration equals immediate enforceability; the debtor's right to contest must be worked through or expire before the judgment can be enforced as a Hong Kong judgment.

Step 5 – Grounds for set-aside are addressed or the period expires. The grounds on which a debtor may apply to set aside registration are set out in Cap. 645. They include: the Mainland court lacked jurisdiction under the test the ordinance prescribes; the judgment was obtained by fraud; enforcement would be contrary to Hong Kong public policy; and related grounds. If the debtor applies, the matter is contested before the Court of First Instance. If no application is made within the applicable period, or if the debtor's application is dismissed, the registration stands and enforcement may proceed.

Step 6 – Enforce as a Hong Kong judgment. A registered Mainland judgment has the same force as a judgment of the Court of First Instance. Enforcement mechanisms available in Hong Kong proceedings then apply: charging orders over property, garnishee orders over bank accounts, enforcement against shares and other assets. The choice of enforcement tool turns on the asset profile of the debtor in Hong Kong.

What documents does the application require?

Documentation is the gate most applications stumble at. Preparing the documents in the correct form from the outset saves time at every subsequent stage. The core documents required for a Cap. 645 registration application are as follows.

First, a certified copy of the Mainland judgment itself. This must come from the Mainland court and must bear the court's seal. A copy obtained from the parties' own records is not sufficient.

Second, the certificate from the Mainland court confirming the effective status of the judgment. This is a separate document from the judgment itself. It confirms that the judgment has taken effect and has not been stayed, set aside, or satisfied. The certificate must be current; a certificate that was accurate some months earlier may not reflect the present position.

Third, certified translations into English of both documents. The translator must be competent and the certification must meet the standards the Hong Kong courts apply. In our cross-border practice, we have seen applications delayed because translations were prepared to a standard appropriate for business purposes but not for court proceedings.

Fourth, the supporting affirmation or affidavit setting out the applicant's evidence on eligibility. This document is prepared by Hong Kong lawyers and brings together the facts relevant to each eligibility condition: the nature of the judgment, the Mainland court's jurisdiction, the absence of exclusions, and the current status of the debt.

Good document preparation is not a formality. A deficient application gives the debtor a foothold to challenge. A well-prepared application gives the court everything it needs to grant registration at the first hearing.

What is the most common mistake – and how does the route avoid it?

The single most common mistake is timing. Specifically, it is the failure to file the registration application before the judgment debtor has moved or concealed assets in Hong Kong.

Cap. 645 does not provide an automatic freeze on assets. Once the debtor knows that a registration application is underway – which happens when notice is served after registration – there may be an interval in which assets are at risk of dissipation. The creditor who delays the application, or who serves informal notice before the legal step is in place, creates a window for the debtor to act.

The route around this problem is to coordinate the registration application with an application for a Mareva injunction (also known as a freezing order, a court order prohibiting the debtor from dealing with or disposing of assets pending enforcement). A freezing order can be obtained on an ex parte basis in urgent cases, and Hong Kong courts have well-developed practice in this area. Counsel on our desk regularly advise clients to assess the freezing-order position at the same time as the registration application – not after it.

The second most common mistake is failing to distinguish between the registration route and the common-law action on the judgment debt. Where the Mainland judgment predates 29 January 2024, Cap. 645 does not apply, and the creditor must bring a common-law action in Hong Kong using the Mainland judgment as the foundation. The procedural requirements, the limitation period, and the grounds of defence differ materially. A creditor who files a Cap. 645 application for a pre-2024 judgment will face an eligibility challenge from the outset.

The sequence described in this guide – eligibility check, document preparation, ex parte application, notice, set-aside period, enforcement – is designed to remove both of these risks when followed in order and without gaps.

If an earlier registration attempt produced an adverse result or stalled at the document stage, a review of the application can identify whether the error is remediable or whether an alternative route – common-law action, or a separate enforcement step via arbitral-award arrangements – remains open.

How does the cross-border interface between Hong Kong and Mainland China shape the process?

Hong Kong and the Mainland operate under different legal systems. Hong Kong is a common-law jurisdiction; Mainland China applies a civil-law system derived from its own statutory codes. The two systems operate independently, and a judgment from one does not automatically run in the other. Cap. 645 creates a bilateral bridge – but it is a bridge with specific entry conditions, not a general pass.

One practical consequence of this interface is that the concepts do not always translate directly. "Effective" under Mainland civil procedure does not mean the same thing as "final and binding" under Hong Kong law. "Jurisdiction" under Cap. 645's connection test reflects neither the exclusive-jurisdiction clause standard of the old regime nor the straightforward presence or submission test of a common-law court. Counsel advising on a Cap. 645 application must be familiar with both systems – or must work alongside advisers who are.

A second consequence is language. Mainland court documents are in Mandarin Chinese. The Hong Kong court requires English translations that meet its procedural standards. Translation errors or uncertified translations are an avoidable source of delay and cost.

A third consequence concerns the scope of enforcement tools. Even after registration, the tools for enforcing the registered judgment are Hong Kong tools: the court orders, the enforcement mechanisms, the asset-tracing resources available in a common-law system. That is an advantage for creditors, because Hong Kong's enforcement regime is well-developed and internationally tested. But it also means that the creditor needs Hong Kong legal support at the enforcement stage, not just at registration.

This practice sits at the intersection of Hong Kong law and Mainland procedure. Lockhart & Yip advises on the international and cross-border dimensions; matters of Hong Kong law are handled with locally licensed firms. For context on enforcing Hong Kong arbitral awards on the Mainland side of this interface, see our guide at enforcing a Hong Kong arbitral award in Mainland China. For creditors with awards rather than judgments, the separate mutual-enforcement arrangements for arbitral awards are addressed at enforcing an arbitral award from the CIS in Hong Kong, which sets out the New York Convention route in a related context.

The sequence described in this guide, with its attention to the cross-border document requirements and the timing of freezing-order applications, is designed specifically for the Mainland–Hong Kong interface. It does not translate without adjustment to the enforcement of judgments from other jurisdictions, including Singapore, the United Kingdom, or the United States, each of which has its own recognition regime or common-law pathway in Hong Kong.

Decision checklist for in-house counsel

The following checklist is designed for use before instructing external counsel. It identifies the threshold questions that determine whether Cap. 645 applies, what documentation is ready, and what parallel steps may be needed.

Eligibility

• Was the Mainland judgment made on or after 29 January 2024?
• Does the judgment relate to a civil or commercial matter?
• Is the judgment excluded from Cap. 645's scope (insolvency, certain IP, arbitration-related, succession, matrimonial)?
• Is the judgment "effective" under Mainland civil procedure – that is, has the appeal period expired or the appellate process concluded?
• Has the judgment been satisfied, stayed, or set aside in the Mainland since it was made?

Documentation

• Has a certified copy of the judgment been obtained from the Mainland court?
• Has the court-issued certificate of effective status been obtained?
• Have both documents been translated into English by a competent translator with certification to court-standard?
• Is the evidence on the Mainland court's jurisdictional basis ready to be set out in a Hong Kong affirmation?

Asset position and timing

• Has the debtor's asset profile in Hong Kong been assessed?
• Is there a risk of dissipation that makes a freezing-order application necessary in parallel with registration?
• If the judgment predates 29 January 2024, has a common-law action on the judgment debt been considered in place of a Cap. 645 application?
• Has the limitation position been checked under both Hong Kong and Mainland law?

Parallel steps

• Are there assets in other jurisdictions that require separate enforcement proceedings?
• If the underlying dispute produced both a court judgment and an arbitral award, has the appropriate enforcement route for each been identified?
• Has locally licensed Hong Kong counsel been engaged to file and conduct the Court of First Instance application?

The sequence above is a starting point, not a substitute for legal advice. The facts of each enforcement matter – the nature of the judgment, the debtor's structure, the asset profile – shape the route in ways that a checklist cannot anticipate. The checklist's function is to ensure that the material questions are on the table before any application is filed.
