The reciprocal enforcement of judgments regime with the Mainland

A judgment won is not a judgment collected. For any creditor or claimant whose counterparty holds assets on the Mainland while proceedings were conducted in Hong Kong – or vice versa – the distance between the courtroom and the debtor's bank account runs through a specific statutory mechanism. Getting that mechanism right is the whole exercise.

The Mainland Judgments in Civil and Commercial Matters (Reciprocal Enforcement) Ordinance (Cap. 645), which came into force on 29 January 2024, is the governing instrument. It allows effective civil and commercial judgments from Mainland courts to be registered and enforced in Hong Kong, and provides a corresponding route for Hong Kong judgments to be used in Mainland courts. The regime applies to judgments made on or after that date and covers both monetary and non-monetary relief, subject to a defined exclusion list.

This note sets out when a foreign principal needs this service, the route Lockhart & Yip runs step by step, the documents and decisions that sit with the client, and the cross-border interface where local counsel join the picture.

Why this matters now: the trigger that brings enforcement to a head

The enforcement question is almost never abstract. It arrives when a Mainland counterparty has stopped paying, when a court order has been issued but ignored, or when a restructuring is imminent and the window to act against assets is narrowing.

Before 29 January 2024, the position was materially more restricted. The predecessor regime – the 2008 choice-of-court arrangement – required the parties to have agreed in writing, before the dispute arose, that the chosen court had exclusive jurisdiction. In practice, most commercial contracts did not satisfy that test. Many creditors with legitimate Hong Kong judgments found the Mainland route effectively closed.

Cap. 645 replaced that exclusive-jurisdiction requirement with a connection-based test. That is a structural shift. It means a far wider pool of Hong Kong civil and commercial judgments are now potentially registrable in the Mainland, and Mainland judgments are registrable here, without the parties having pre-committed to exclusive jurisdiction in writing.

For a foreign principal whose group operates across the boundary, the practical question is no longer "can we use this route?" but "how quickly, and with what documents in hand?" That is where the enforcement-risk trigger bites: the answer to both sub-questions depends entirely on preparation made before the enforcement window opens.

In our cross-border practice, the matters that stall do so for predictable reasons. The certified copy of the judgment is not yet authenticated. The judgment is final and effective on its face but has not yet cleared a domestic appeal period. The exclusion list has not been checked against the subject matter of the relief. Each of those points has a fix – but only if it is identified before the application goes in.

What the Cap. 645 regime actually covers – and what it excludes

Cap. 645 applies to civil and commercial judgments in both monetary and non-monetary form, made by a Mainland people's court and rendered effective on or after 29 January 2024. The corresponding route for Hong Kong judgments runs in parallel, using a certified copy and a certificate procedure with the relevant Mainland court.

The exclusion list matters as much as the coverage. Judgments in insolvency proceedings, certain intellectual-property and patent matters, certain arbitration-related proceedings, succession, and matrimonial and family matters sit outside the regime. A creditor who has obtained a Mainland judgment that touches one of those excluded categories may need to consider an alternative route – through the arbitral-award arrangements, through common-law recognition arguments, or through direct enforcement proceedings in the jurisdiction where the assets sit.

The connection-based test that replaced exclusive jurisdiction is not a low bar. There must be a genuine connection between the dispute and the court that heard it. What constitutes a sufficient connection is a question that our desk examines carefully against the facts of each matter, because an application that fails on this ground is not a minor procedural setback – it delays the entire enforcement sequence and alerts the debtor.

Non-monetary relief – injunctions, specific performance orders, declarations – is within the regime's scope under Cap. 645. That is an expansion over the prior arrangement and opens enforcement options that creditors and counterparties did not previously have through the statutory route. Whether a specific non-monetary order is enforceable against a particular class of asset in the receiving jurisdiction is a separate analysis that must be done before the application is filed.

How does this regime sit alongside the arbitral-award arrangements?

The reciprocal-enforcement regime under Cap. 645 is distinct from the arbitral-award mutual enforcement mechanism, which runs under the 1999 Arrangement and the 2020 Supplemental Arrangement. Since the 2021 amendment to the arbitral-award arrangements, simultaneous enforcement applications in both Hong Kong and the Mainland have been permitted for arbitral awards. That optionality does not exist in the same form under Cap. 645 for court judgments.

Why does this matter for a foreign principal deciding between litigation and arbitration? The enforcement endgame is different depending on the dispute-resolution clause in the contract. A party holding a Hong Kong court judgment uses Cap. 645 to reach Mainland assets. A party holding a Hong Kong-seated HKIAC (Hong Kong International Arbitration Centre) award uses the arbitral-award arrangements. The two routes are not interchangeable, and filing under the wrong one is not a technical error that can be corrected without cost.

For matters already in dispute where the contract is silent or ambiguous on seat, the choice between litigating to a court judgment versus proceeding to an arbitral award shapes every downstream enforcement step. We map that choice early, because the asset jurisdiction – where the debtor's property actually sits – determines which route has the better enforcement record and the shorter timeline.

There is also an interaction with the interim-measures arrangement. Since 1 October 2019, parties to Hong Kong-seated arbitrations may apply to Mainland courts for interim measures before or during proceedings. That mechanism is not available to parties in Hong Kong court litigation. For a creditor worried about asset dissipation during proceedings, that distinction can be dispositive.

The route we run: step by step

The enforcement sequence under Cap. 645 has several distinct stages. Each has a legal condition that must be met before the next becomes available. Our role is to manage those conditions in sequence, bring locally licensed Hong Kong firms in at the right points, and keep the client oriented on the decisions that belong to them alone.

Step 1 – Judgment verification and exclusion-list check. Before any application is filed, the judgment must be confirmed as final and effective under the law of the issuing court. The subject matter is checked against the exclusion list. The connection-based test is assessed on the facts. This step happens on our desk, drawing on the certified judgment documents the client provides.

Step 2 – Document preparation. A certified copy of the judgment, a certificate of effectiveness, and a translation (where the judgment is in a language other than the official language required by the receiving court) must be assembled. For Mainland judgments being registered in Hong Kong, the document set is prepared for the Court of First Instance. For Hong Kong judgments being used in the Mainland, the certificate procedure runs differently and engages allied counsel admitted in the Mainland.

Step 3 – Registration application at the Court of First Instance. This is the procedural heart of the Hong Kong side. A locally licensed Hong Kong firm, working alongside our desk, files the registration application. We have prepared the documents and the supporting analysis; local counsel conduct the filing and manage the court procedure. The registration, once granted, gives the judgment the same force as a Hong Kong judgment.

Step 4 – Post-registration enforcement. A registered Mainland judgment can be enforced by the same mechanisms available for a domestic Hong Kong judgment: charging orders, garnishee proceedings, and other execution measures against assets within the jurisdiction. Where assets also sit in the Mainland, we co-ordinate with allied counsel admitted there on parallel or sequential steps.

Step 5 – Monitoring and contingency planning. Asset positions change. A debtor who was cooperative at the outset of registration may become evasive once enforcement commences. Our desk maintains oversight of the post-registration steps and advises on contingency measures – including, where justified on the facts, applications for recognition in a third jurisdiction where assets have been moved.

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

The cross-border interface: Hong Kong, the Mainland, and the offshore layer

The reciprocal-enforcement regime operates between two legal systems that share a constitutional boundary but maintain distinct court hierarchies, procedural codes, and enforcement cultures. Hong Kong's common-law courts apply Cap. 645 against the background of a binding-precedent system and an established practice of recognising foreign judgments. Mainland people's courts apply their own civil-procedure rules to registration applications for Hong Kong judgments.

A foreign principal – a European group, an Asian family office, a CIS-based trading house – holding a Mainland judgment is engaging with both systems simultaneously. The Hong Kong registration step is the one we manage directly (alongside locally licensed Hong Kong firms). The Mainland-side execution of a registered Hong Kong judgment is managed through allied counsel admitted in the relevant Mainland jurisdiction, with our desk setting the strategic direction and ensuring the cross-border steps are sequenced coherently.

The offshore layer adds a third dimension. Many Greater China-facing structures interpose a BVI or Cayman holding entity above the Hong Kong operating company. Where the debtor's assets are held through such an entity, the enforcement analysis must extend to the offshore jurisdiction: what recognition mechanism is available there, whether the Hong Kong registered judgment can be relied upon as a predicate, and whether an independent application in the offshore court is required.

Consider a mid-market scenario. A European trading group held a substantial Mainland judgment against a counterparty whose assets were held partly in the Mainland and partly through a BVI entity with a Hong Kong bank account. The matter came to us in early 2025 after an initial filing had stalled on the connection-based test. We re-analysed the jurisdictional connection, re-prepared the document set, and co-ordinated the Hong Kong registration alongside a parallel application through allied BVI counsel. The registration proceeded in Hong Kong without further challenge; the BVI step was completed in sequence.

That pattern – Mainland judgment, Hong Kong registration, offshore or third-jurisdiction follow-on – is common in our desk's practice. The asymmetry of steps between the systems, and the need to co-ordinate them without conflicting filings, is where international counsel adds the clearest value.

A second pattern runs in the other direction. A Hong Kong court judgment against a Mainland defendant whose only meaningful assets are in China. Here the enforcement route runs through the Mainland, using the certificate procedure under Cap. 645. The client needs a clear read on the connection test, the exclusion list, and the practical enforcement environment in the specific Mainland jurisdiction where assets sit – because enforcement culture and court capacity vary materially between provinces. That read is what we provide before the client commits to the Mainland route or decides to pursue an alternative asset location.

What foreign principals get wrong

The most common error is treating registration as the end of the exercise. A judgment registered with the Court of First Instance in Hong Kong is a legal step, not a bank transfer. The enforcement mechanics that follow – locating the debtor's assets, obtaining charging orders or garnishee orders, managing opposition from the debtor or third-party creditors – are a separate exercise that can take considerably longer than the registration itself.

The second common error is filing without a complete document set. The certified copy of the Mainland judgment must satisfy specific formal requirements. An incomplete filing does not merely cause delay; it alerts the debtor and may prompt asset movement. Counsel on our desk regularly see applications that were filed optimistically and then stalled at the document-verification stage. Preparing correctly at Step 1 costs less, in every sense, than recovering from a failed application.

The third error is conflating the Cap. 645 route with the arbitral-award arrangements. They share a cross-border character but are governed by different instruments, subject to different exclusion lists, and carry different procedural timelines. A creditor who spent litigation resources on a Hong Kong court judgment in the belief that the 2021 simultaneous-enforcement amendment applied to it has spent those resources incorrectly.

The fourth error – relevant for any matter where the Mainland judgment post-dates a restructuring or insolvency event – is failing to check whether the insolvency exclusion in Cap. 645 affects the enforceability of the specific relief obtained. A judgment that includes elements touching on insolvency proceedings may be only partially registrable. That analysis must be done before filing.

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 the position.

Documents and decisions the client must own

Our role in this service is to analyse, structure, and co-ordinate. There are, however, decisions and documents that sit with the client alone – and which cannot be substituted by counsel.

The client must obtain and hold the original certified copy of the judgment from the issuing court. This document is the jurisdictional foundation of the entire application. No copy obtained through intermediaries and no uncertified translation is a substitute. Where the judgment was issued by a Mainland people's court, the certification procedure runs through that court's official channel; where it was issued by a Hong Kong court, the certificate procedure is managed alongside locally licensed Hong Kong firms.

The client must also make the core commercial decision about sequencing: whether to pursue registration in Hong Kong first, in the Mainland first, or simultaneously where the regime permits, and whether to seek interim relief against specific assets before or during the registration step. These are not purely legal decisions. They require the client's assessment of the debtor's likely response, the risk of asset dissipation, and the priority the client assigns to speed versus cost.

The client's instructions on asset targets are equally critical. A registration application without a clear view of where the debtor's enforceable assets sit is a filing looking for a purpose. We conduct our own preliminary analysis of the enforcement landscape, but the client's commercial intelligence about the counterparty – account locations, property holdings, operating subsidiaries – is information that only the client holds and that must be shared before the enforcement route is designed.

Finally, the client must be prepared to make decisions under time pressure. A debtor who becomes aware that registration is imminent may move assets. The enforcement sequence rewards speed and preparation in roughly equal measure. Clients who arrive with their documents in order and a clear instruction on asset targets move faster than those who arrive with a question and a hope.

Decision matrix: choosing the right enforcement route

Situation A – Mainland judgment, debtor has Hong Kong assets: use Cap. 645 to register with the Court of First Instance in Hong Kong; enforcement then proceeds by Hong Kong execution mechanisms; timeline depends on document readiness and court scheduling; primary risk is that the connection-based test is not clearly satisfied on the judgment's face.

Situation B – Hong Kong court judgment, debtor has Mainland assets only: use the Cap. 645 certificate procedure for Mainland registration; allied counsel admitted in the relevant Mainland jurisdiction manage the local execution steps; risk includes variance in enforcement practice between Mainland provinces; contingency is a parallel application in an offshore jurisdiction where the debtor has subsidiary assets.

Situation C – Hong Kong-seated arbitral award, debtor has both Mainland and Hong Kong assets: use the arbitral-award arrangements, not Cap. 645; since the 2021 amendment, simultaneous applications in both jurisdictions are available; this is materially faster than sequential filing for a creditor under time pressure from asset dissipation risk.

Situation D – Judgment falling within an excluded category (insolvency, matrimonial, certain IP matters): Cap. 645 is unavailable or only partially available; consider common-law recognition in Hong Kong (which has its own requirements); consider whether a parallel arbitral route exists or whether an application in the debtor's home jurisdiction is needed; seek advice on the interaction with any concurrent insolvency or restructuring proceedings.

Situation E – Offshore holding layer sits between the judgment debtor and the assets: the Hong Kong registration step handles Hong Kong-sited assets; a separate application through allied counsel in the BVI, Cayman Islands, or the relevant offshore centre is required for assets held there; the two applications are co-ordinated but procedurally independent.

Self-assessment: is your matter ready for the Cap. 645 route?

The following questions identify whether a matter is positioned to use the reciprocal-enforcement regime effectively. A "no" or "uncertain" answer to any of them signals a step that must be resolved before filing.

• Is the judgment final and effective under the law of the issuing court?
• Was the judgment made on or after 29 January 2024?
• Does the subject matter of the judgment fall outside the exclusion list (insolvency, certain IP/patent, certain arbitration-related matters, succession, matrimonial)?
• Is there a sufficient connection between the dispute and the issuing court to satisfy the connection-based test?
• Is a certified copy of the judgment available from the issuing court's official channel?
• Have you identified specific assets of the debtor within the jurisdiction where registration is sought?
• Have you assessed whether interim-measures applications are needed before or concurrent with registration?
• If assets sit offshore, has the offshore enforcement step been scoped alongside the main application?

If your matter passes each of those points, the application sequence can begin. If one or more are uncertain, those are the first instructions for our desk.

Our broader disputes and arbitration practice covers the full range of cross-border enforcement work, from the initial dispute-resolution clause through to final execution against assets across Greater China and the offshore centres.

For matters involving a non-Chinese element or a debtor with assets in multiple jurisdictions, our cross-border enforcement matter note on UK-based debtors illustrates the approach our desk takes when co-ordinating enforcement steps across two or more legal systems simultaneously.
