Enforcing a foreign judgment in Hong Kong is possible through two principal routes: a common-law action on a debt (available for judgments from most jurisdictions) and, for judgments originating from Mainland China, the statutory regime established by the Mainland Judgments in Civil and Commercial Matters (Reciprocal Enforcement) Ordinance (Cap. 645), which came into force on 29 January 2024. The process involves filing in the High Court of Hong Kong, satisfying defined admissibility requirements, and navigating procedural steps that can span several months depending on the complexity of the case and the availability of the debtor's assets. International businesses dealing with unpaid invoices or unrecovered debts should understand both routes before deciding how to proceed.
Two Routes to Enforcement: Common Law and Statute
Most foreign creditors rely on the common-law action on a debt. Under this route, a foreign judgment is treated as creating a debt obligation between the parties, and the creditor commences fresh proceedings in the Hong Kong High Court to have that debt recognised and enforced locally. There is no registration mechanism for most foreign judgments; instead, the judgment becomes the cause of action itself.
For judgments from Mainland China in civil and commercial matters, the picture changed significantly when Cap. 645 took effect on 29 January 2024. This Ordinance provides a dedicated statutory framework under which qualifying Mainland judgments may be registered in Hong Kong and enforced directly, without the need to re-litigate the underlying claim. Creditors holding Mainland court orders should assess whether their judgment satisfies the conditions under Cap. 645 before defaulting to the common-law route.
Threshold Requirements: What Makes a Foreign Judgment Enforceable
Before filing anything in the High Court of Hong Kong, you must confirm that the judgment you hold meets the baseline admissibility criteria developed through Hong Kong case law and, where applicable, the conditions under Cap. 645. For the common-law route, the key requirements are:
- Final and conclusive judgment: The foreign court must have delivered a final decision on the merits. Interlocutory orders, provisional measures, and orders that remain subject to appeal in a manner that undermines finality generally do not qualify.
- Fixed sum of money: The judgment must be for a definite monetary amount. Non-monetary orders – injunctions, specific performance, declaratory relief – cannot be enforced via this route.
- Jurisdiction of the foreign court: Hong Kong courts will recognise the foreign court's jurisdiction if the defendant was present in that country, submitted to the court's jurisdiction, or agreed by contract to that forum.
- No public policy bar: The judgment must not conflict with Hong Kong public policy, and the proceedings must not have been obtained by fraud.
- Compliance with natural justice: The defendant must have been given adequate notice and an opportunity to be heard.
Under Cap. 645, additional conditions specific to Mainland judgments apply, including requirements relating to the type of proceedings, the court of origin, and the finality of the Mainland decision. Practitioners should review the Ordinance carefully for any category exclusions before filing a registration application.
Step-by-Step Procedure: Common-Law Action on a Debt
The following sequence reflects the typical path taken by a foreign creditor seeking enforcement through the High Court of Hong Kong using the common-law route.
Step 1 – Gather and authenticate documents
You will need a certified copy of the foreign judgment, a translation into English (if the judgment is in another language), and evidence of service of the original proceedings on the defendant. Documents originating outside Hong Kong may need to be authenticated by apostille or notarisation, depending on the country of origin and the court's requirements.
Step 2 – Issue a writ of summons in the High Court
A writ is issued in the Court of First Instance of the High Court of Hong Kong. The claim is framed as an action on the debt created by the foreign judgment. The writ must be served on the defendant; if the defendant is outside Hong Kong, leave to serve out of the jurisdiction is required, and the applicant must satisfy the court that Hong Kong is the appropriate forum.
Step 3 – Obtain summary judgment
Because the underlying merits have already been determined by the foreign court, the creditor will ordinarily apply for summary judgment under the Rules of the High Court. The defendant has the opportunity to resist, principally by arguing one of the recognised defences: fraud, public policy, lack of jurisdiction, or denial of natural justice. If no real defence is raised, the court will enter judgment for the claimant without a full trial.
Step 4 – Enforcement of the Hong Kong judgment
Once a Hong Kong judgment is obtained, the full range of local enforcement tools becomes available. These include:
- Charging orders over the debtor's property or shareholdings registered with the Companies Registry.
- Garnishee orders attaching bank accounts or debts owed to the debtor by third parties.
- Writ of fieri facias (fi. fa.) directing the seizure of the debtor's goods.
- Bankruptcy or winding-up proceedings, which can exert significant commercial pressure and may lead to asset realisation – see our overview of insolvency and restructuring work in Hong Kong.
- Examination of judgment debtor, compelling the debtor to disclose assets under oath before a master of the court.
Late payment interest on the Hong Kong judgment will accrue at the rate applicable under Hong Kong law from the date of the original foreign judgment or from the date of the Hong Kong judgment, depending on how the claim is pleaded. The precise rate depends on the applicable court rules and any contractual provisions, so this should be addressed in the pleadings.
Asset Freezing Before or During Proceedings
If there is a real risk that the debtor will dissipate or remove assets before enforcement is complete, it is possible to apply for a Mareva injunction (asset freezing order) from the Hong Kong High Court. This is a significant and powerful remedy, but the threshold is demanding: the applicant must demonstrate a good arguable case, the existence of assets within the jurisdiction, and a real risk of dissipation. The application is typically made without notice to the defendant at the outset, but the defendant has the right to apply to discharge it promptly thereafter.
Asset freezing applications are time-sensitive and require careful preparation. If you are considering this step in connection with an unpaid invoice or a disputed payment order, early legal advice is essential.

Cap. 645: Enforcing Mainland Chinese Judgments Since January 2024
The Mainland Judgments in Civil and Commercial Matters (Reciprocal Enforcement) Ordinance (Cap. 645) came into force on 29 January 2024, replacing the previous regime under the Mainland Judgments (Reciprocal Enforcement) Ordinance (Cap. 597) for judgments that fall within its scope. The new Ordinance broadens the categories of eligible judgments and introduces a registration-based mechanism: a qualifying Mainland judgment is registered in the Hong Kong High Court and thereafter has the same force and effect as a judgment of that court.
Key practical points under Cap. 645 include the time limit for registration applications, the grounds on which registration may be refused (broadly analogous to the common-law defences but set out in statutory form), and provisions dealing with partial enforcement where only part of a judgment is enforceable. Cross-border operators with commercial disputes involving Mainland counterparties should treat Cap. 645 as the primary reference point, as it offers a more streamlined path than a common-law action where the conditions are satisfied.
Realistic Timelines
Timelines in Hong Kong enforcement matters vary considerably. As a general indication:
- Uncontested summary judgment application: From issuing the writ to obtaining judgment, the process often takes between three and six months, assuming service is effected promptly and no jurisdictional complications arise.
- Contested proceedings: If the defendant mounts a defence – even a holding argument – the timetable can extend significantly, as interlocutory steps and directions hearings add time before any substantive hearing is listed.
- Cap. 645 registration: A registration application, if uncontested, may proceed more quickly than a common-law action, but the timeline depends on the court's current listing schedule and the complexity of the documentation.
- Post-judgment enforcement steps: Charging orders, garnishee orders, and examination of the judgment debtor each involve further applications, each with their own procedural timetable.
International businesses managing cash flow and debt collection workflows should factor these timelines into their planning and consider whether interim measures – including asset freezing – are appropriate from the outset.
Common Errors Made by Foreign Clients
Experience in cross-border enforcement work reveals several recurring mistakes that delay or undermine enforcement efforts in Hong Kong:
- Delay in commencing proceedings: Limitation periods apply. Under Hong Kong law, an action on a foreign judgment is subject to a limitation period, and allowing time to pass unnecessarily reduces the prospects of recovery.
- Inadequate document authentication: Courts are strict about the form of certified copies and translations. Documents that do not comply with procedural requirements will need to be resubmitted, causing delay and additional cost.
- Misidentifying the correct enforcement route: Attempting to rely on the common-law route for a Mainland Chinese judgment that falls within Cap. 645 – or vice versa – leads to procedural complications and wasted costs.
- Failing to identify and freeze assets early: By the time a judgment is obtained, a debtor who has been forewarned may have restructured holdings, transferred property, or removed funds from Hong Kong. Asset tracing and freezing should be considered before proceedings are initiated where there is a material risk of dissipation.
- Ignoring HKIAC arbitration clauses: Where the underlying contract contains an arbitration clause referring disputes to the HKIAC or another institution, a foreign court judgment obtained in breach of that clause may face jurisdictional challenges in Hong Kong. This must be assessed before any filing.
- Treating enforcement as automatic: Obtaining a Hong Kong judgment on a foreign debt is not the end of the process. Identifying assets, selecting the right enforcement tool, and executing that tool all require further steps and, often, further applications to the court.

Cost Drivers
The cost of enforcing a foreign judgment in Hong Kong depends on several factors. Court filing fees are set by tariff and vary according to the amount claimed. Legal fees depend on the complexity of the matter, the degree of opposition from the defendant, and the number of post-judgment steps required. Translation and authentication costs can be material where the original judgment is in a language other than English and involves a lengthy decision with annexes.
In contested matters, costs can increase substantially if the defendant challenges service, disputes jurisdiction, or seeks to set aside a summary judgment. Where asset tracing is necessary – either because the debtor conceals assets or holds them through corporate structures registered with the Companies Registry – the involvement of forensic practitioners adds further expense. Creditors should conduct a frank cost-benefit analysis before committing to enforcement, particularly where the judgment sum is modest relative to the likely procedural cost.
Decision Checklist Before Filing
Before instructing lawyers to commence enforcement proceedings in Hong Kong, it is worth working through the following questions:
- Is the judgment final, conclusive, and for a fixed monetary sum?
- Did the foreign court have jurisdiction recognised under Hong Kong common law or, for Mainland judgments, under Cap. 645?
- Are there any fraud, public policy, or natural justice concerns that a defendant might raise?
- Does the defendant have identifiable assets in Hong Kong? If so, are those assets at risk of dissipation?
- Has the limitation period for bringing an action on the judgment been checked?
- Does the underlying contract contain an arbitration clause that could complicate enforcement?
- Is this a Mainland Chinese judgment that should be assessed under Cap. 645 rather than the common-law route?
- Has the cost of enforcement been weighed against the realistic recoverable amount?
