Where recognising a court judgment from Mainland China in Hong Kong stands now

Recognising a court judgment from Mainland China in Hong Kong is now governed by the Mainland Judgments in Civil and Commercial Matters (Reciprocal Enforcement) Ordinance (Cap. 645), which came into force on 29 January 2024 and replaced the narrower choice-of-court regime that had operated since 2008. The new ordinance opens registration to a significantly wider class of Mainland civil and commercial judgments – monetary and non-monetary – and removes the old requirement that the parties had selected the Mainland courts by written exclusive agreement. For creditors and claimants with Hong Kong-connected counterparties, the shift is material.

This analysis sets out the current position, reads the cross-border interface between the two systems, and identifies where the risks and the real procedural work now sit.

What is commercially at stake when a Mainland judgment needs to move south

The commercial question is almost always the same: the assets are in Hong Kong, but the judgment was obtained in a Mainland people's court. A creditor holding a Mainland judgment against a counterparty with Hong Kong-held shares, bank deposits, or real property has one practical objective – converting that paper entitlement into enforceable process in the territory where the assets actually sit.

This matters for a specific class of cross-border transaction. Consider a Mainland supplier with a debt judgment against a joint-venture partner whose holding entity is incorporated in Hong Kong. Or a Mainland creditor in a dispute over a services contract who has pursued proceedings to a Mainland judgment while the opposing party's liquid assets remain in a Hong Kong account. In both situations, the judgment's value is entirely contingent on the creditor's ability to register and enforce it south of the boundary.

Before January 2024, that exercise was hedged with a significant structural condition: under the old regime, the Mainland court in question generally needed to have exercised jurisdiction pursuant to a written exclusive jurisdiction agreement. Many genuine commercial disputes – particularly those arising from oral contracts, implied terms, or multi-court proceedings – fell outside that perimeter entirely. The judgment sat unregistrable in Hong Kong, and the creditor was left to consider fresh action or alternative enforcement routes. That structural barrier is now substantially reduced.

How does Cap. 645 actually change the recognition position?

The Mainland Judgments in Civil and Commercial Matters (Reciprocal Enforcement) Ordinance replaces the requirement for an exclusive jurisdiction agreement with a connection-based test. The Mainland court must have had a jurisdictional basis recognised under the new ordinance, but the range of such bases is considerably broader than before. Both monetary and non-monetary judgments are in scope, which is a significant extension: injunctions, specific performance orders, and declaratory relief issued by Mainland courts can now, in principle, be brought to Hong Kong for registration.

The mechanism itself remains registration with the Court of First Instance of the High Court. A certified copy of the Mainland judgment and the supporting certificate are the core documents. Once registered, the judgment is treated as a judgment of the Hong Kong court for enforcement purposes. That treatment means the full range of Hong Kong enforcement tools – garnishee orders, charging orders over shares and property, appointment of a receiver – becomes available to the creditor.

The ordinance also carries an exclusion list. Insolvency matters, certain intellectual property and patent decisions, some arbitration-related orders, succession proceedings, and matrimonial causes sit outside the regime. These exclusions reflect both practical reciprocity concerns and the distinct procedural regimes applicable to those categories in each system. A creditor holding a judgment touching one of those excluded categories should not assume the Cap. 645 route is available without a careful classification of the underlying matter.

The temporal boundary is equally important. Cap. 645 applies to Mainland judgments made on or after 29 January 2024. Judgments predating that commencement fall outside the new ordinance. Those earlier judgments are not necessarily unenforceable in Hong Kong – common law recognition routes remain theoretically available – but they require a different analysis and carry considerably more procedural uncertainty.

Where does the old exclusive-jurisdiction requirement leave pre-2024 creditors?

This is where the structural complexity bites hardest. A creditor holding a Mainland judgment from, say, 2021 or 2022 sits outside Cap. 645 entirely. The old Cap. 597 regime – which did require an exclusive jurisdiction clause – may apply if the original contract contained the necessary agreement, but that regime was narrow and its practical record uneven. For judgments that never qualified under Cap. 597, the creditor's residual option is common law recognition.

Common law recognition of a foreign judgment in Hong Kong requires, at minimum, that the originating court had jurisdiction in the international sense, that the judgment is final and conclusive, and that the debt is for a fixed sum. The Mainland courts present a particular complication here: the common law position on whether a Mainland people's court constitutes a recognised foreign court for Hong Kong common law purposes has been contested, and the result is that common law recognition of Mainland judgments in Hong Kong has not produced a settled, reliable route. We regularly advise creditors in exactly this position – holding a valid, fully reasoned Mainland judgment and needing to work through whether any recognition route remains workable before assets dissipate.

The practical read is that pre-2024 creditors face a materially harder exercise. If the judgment is old enough that a fresh Mainland action is time-barred, the options narrow further. Parties who are currently pursuing Mainland litigation – or who anticipate needing to – should be structuring their dispute strategy with the January 2024 commencement date explicitly in mind.

How does the cross-border interface between the two legal systems actually work in practice?

Hong Kong operates a common law system. The Mainland courts operate under a distinct civil-law-derived system. The two systems interact across the boundary through a series of bilateral Arrangements – some statutory, some treaty-equivalent – rather than through the general operation of the New York Convention, which applies to arbitral awards rather than court judgments in this context. Cap. 645 is the current primary instrument for court-judgment recognition, and it reflects a deliberate design choice: mutual recognition grounded in a specific bilateral framework rather than general principles of private international law.

That design has practical implications. When a Hong Kong court registers a Mainland judgment under Cap. 645, it does not re-examine the merits. The registration exercise is not an appeal. The Hong Kong court's task is to verify that the formal conditions for registration are met – jurisdiction, finality, absence of a ground for refusal – and then to register the judgment as its own. The grounds for refusal mirror those familiar from bilateral enforcement regimes internationally: public policy, natural justice, prior inconsistent judgment, fraud. In our cross-border practice, the public policy ground attracts the most scrutiny on complex cross-border matters, but it is a narrow ground and is not a general licence to re-litigate the underlying dispute.

The reciprocal dimension is equally important to commercial parties. Cap. 645 is a reciprocal instrument: Hong Kong judgments may be brought to the Mainland for enforcement by way of a parallel mechanism. This means that a party who commences proceedings in Hong Kong and obtains a Hong Kong judgment has, since January 2024, a clearer route to enforcement in the Mainland than was previously available. The structure therefore cuts both ways and affects how parties think about forum selection at the outset of a dispute.

There is a separate, parallel architecture for arbitral awards, which runs through the 1999 Arrangement and the 2020 Supplemental Arrangement. Arbitral awards and court judgments travel different routes – the interim-measures arrangement that has been in place since 1 October 2019 applies specifically to Hong Kong-seated arbitrations, not to court proceedings. A party seeking Mainland-side interim relief in support of a Hong Kong arbitration can apply to a Mainland people's court; that route is not available to support a court-based cross-border claim in the same way. Understanding which route the matter sits on – arbitration or court – is the first question in any cross-border enforcement planning exercise.

What are the real risk points for creditors and their advisers?

The first risk is classification error. Creditors and in-house teams sometimes assume that because a Mainland judgment is relatively recent and the counterparty holds Hong Kong assets, registration under Cap. 645 is straightforward. It is not. The classification of the subject matter – whether it falls inside or outside the exclusion list – requires a careful read of the Mainland judgment's operative provisions, not just its general commercial character. A judgment that is nominally a contract dispute but turns on matters touching arbitration-related orders or insolvency issues may be excluded even if the dominant claim looks commercial.

The second risk is timing. A creditor who delays registration while the counterparty's Hong Kong assets are dissipated or transferred has a real problem. Cap. 645 does not freeze assets on application; the registration process takes time, and the creditor may need to consider whether interim relief – a Mareva injunction over Hong Kong assets – is required before or alongside the registration application. That is a separate exercise involving the Hong Kong courts' inherent jurisdiction and the Companies Ordinance where share interests are involved.

The third risk is the reciprocal context. A party who is a defendant to Mainland proceedings and holds assets in Hong Kong now faces a more credible enforcement risk than before January 2024. Defendants in Mainland civil proceedings who have historically assumed that Hong Kong assets were beyond reach should revisit that assumption. The structural shift that Cap. 645 introduced is not merely a technical procedural change; it represents a meaningful increase in the enforcement reach of Mainland judgments into the territory.

A fourth, more nuanced risk concerns the interaction between Cap. 645 and other enforcement tools. Where a Mainland judgment creditor has already commenced fresh Hong Kong proceedings – a common response to the old regime's limitations – the relationship between those proceedings and a Cap. 645 registration application requires careful management. Running both in parallel may produce procedural complications or an argument from the debtor that the creditor has elected one route. Getting the sequencing right is where the real work lies.

If an earlier enforcement attempt produced a stalled or adverse result under the old regime, the opening of Cap. 645 may reopen options that were previously closed. A second read of the judgment, the contract, and the asset position is the right starting point. To discuss an earlier attempt and what routes remain available, contact info@lockhartyip.com.

How does this compare with the arbitral award enforcement route?

The standard question from in-house teams and CFOs managing cross-border credit exposure is whether the court-judgment route or the arbitration route produces a more reliable enforcement outcome across the boundary. The honest answer is that the two routes are not substitutes; they reflect fundamentally different dispute mechanisms, and the choice between them should be made at the contract stage, not at the enforcement stage.

That said, the comparative picture has some useful benchmarks. For arbitral awards seated in Hong Kong, the 1999 Arrangement and the 2020 Supplemental Arrangement provide a well-established, tested route to Mainland enforcement. The simultaneous-application permission introduced by the 2021 amendment to that arrangement means that an award creditor can pursue enforcement in both jurisdictions concurrently, which is a genuine advantage over the sequential approach that was previously required. The Hong Kong-seated arbitral-award route has a longer operational track record, a larger body of practitioner experience, and a more settled procedural map than the new Cap. 645 regime.

Cap. 645, by contrast, is new. The January 2024 commencement means that the courts in both jurisdictions are still building the interpretive record on questions such as the scope of the exclusion list, the application of the public policy ground, and the jurisdictional-connection test. That is not a reason to avoid the route – it is a sound statutory mechanism and its design reflects serious technical work on both sides. But it does mean that the first wave of contested registration applications will be watched closely by practitioners, and the early decisions will shape how the regime operates in practice.

For parties with a choice – those entering new long-form commercial contracts with Mainland counterparties – the sensible approach is to think carefully about what the enforcement endgame looks like before selecting a dispute-resolution clause. An arbitration clause with a Hong Kong seat gives access to a tested bilateral regime. A court-based exclusive jurisdiction agreement in favour of a Mainland court now gives access to Cap. 645. The two produce different procedural maps and different interim-relief options. Our desk sees both regularly, and the structural analysis at the contract stage remains the single most valuable step a cross-border counsel can take to protect the client's enforcement position.

What foreign counsel and in-house teams frequently get wrong

The most common analytical error we encounter from foreign counsel – European, US, and even other Asian-law teams – is treating the Mainland–Hong Kong enforcement interface as if it operated under the New York Convention's framework. It does not. The New York Convention applies to arbitral awards, and even then the Hong Kong–Mainland pathway runs through the bilateral Arrangements rather than the Convention itself. Court judgments are an entirely separate category. A creditor who arrives with a Mainland judgment and asks about "enforcing under the Convention" has started from the wrong instrument.

A second error is underestimating the role of document form. The Cap. 645 mechanism is not a common law recognition action where the judgment can be exhibited to an affidavit and left for the court to assess. It requires specific documentation from the Mainland side – a certified copy of the judgment and a certificate in the prescribed form from the Mainland court. Obtaining those documents from the originating court can take time, particularly where the Mainland proceedings concluded some time ago or where the relevant registry has practical backlogs. A creditor who has not yet taken steps to obtain the Mainland-side certification documents is not, in practice, ready to commence registration proceedings.

A third error concerns the distinction between registration and enforcement. Registration under Cap. 645 converts the Mainland judgment into a Hong Kong judgment for enforcement purposes. Enforcement is then a second step – executing against specific assets using Hong Kong enforcement tools. The two steps are sequential, and each has its own procedural requirements and timing. A creditor who assumes that registration automatically freezes or transfers assets will be surprised by the need for a further execution phase.

A micro-scenario illustrates the sequencing problem. A mid-size European manufacturing group with a Mainland joint-venture partner obtained a judgment from a Mainland intermediate people's court in early 2024 – after the Cap. 645 commencement date. The counterparty held shares in two Hong Kong-incorporated companies. The creditor's European lawyers advised that registration "should be straightforward" under the new regime. In our cross-border practice, we were instructed after an initial filing difficulty: the certified copy of the judgment that had been obtained from the Mainland registry was not accompanied by the prescribed certificate, and the translation into English had been prepared without a notarisation step that the Hong Kong court required. The filing was rejected. Re-sequencing the documentation exercise and coordinating with allied counsel on the Mainland side to obtain the correct certification added several months to the timeline – months during which the creditor had no registered judgment and no charging order over the counterparty's Hong Kong shares. A Mareva application was ultimately required to preserve the position while the documentation was regularised.

Where the risk sits now and where the regime is heading

Cap. 645 represents the most significant structural shift in cross-border civil enforcement between the Mainland and Hong Kong in a generation. The removal of the exclusive-jurisdiction prerequisite, the extension of scope to non-monetary judgments, and the connection-based jurisdictional test collectively expand the practical population of registrable judgments by a substantial margin. That expansion is real and it matters to any creditor managing cross-border exposure in the Greater China corridor.

The current risk concentration, in our read, sits in three areas. First, the interpretation of the exclusion list remains to be tested. The categories excluded from Cap. 645 – insolvency-adjacent matters, certain IP decisions, arbitration-related orders – are not always cleanly delineated from the underlying commercial dispute. The first contested decisions on scope will define the working edges of the regime for practitioners and their clients.

Second, the reciprocal exposure for Hong Kong-based defendants in Mainland proceedings is now materially higher. Parties who structure their Hong Kong-held assets on the assumption that Mainland judgments cannot reach them are operating on an outdated risk model. The restructuring of asset-holding arrangements, the management of timing between Mainland proceedings and Hong Kong-side steps, and the proactive use of Hong Kong-side interim relief are all now more urgent questions for defendants than they were before January 2024.

Third, the interaction between Cap. 645 and the broader architecture of cross-border insolvency, corporate restructuring, and securities enforcement in Hong Kong is still being mapped. Where a Mainland judgment is obtained against a company that is simultaneously the subject of Hong Kong winding-up proceedings, the intersection of the registration mechanism and the insolvency exclusion requires careful analysis that the courts have not yet had to address in depth.

Our desk is tracking the developing case record on Cap. 645 closely. For parties entering new Mainland-connected transactions, the contracts and dispute-resolution clauses they execute today will determine which enforcement routes are available two, three, or five years from now. Getting that architecture right at the outset is the most cost-effective step available.
