A company wins a court judgment in Germany, France, or the United States against a Belgian-domiciled debtor. The debtor has assets in Belgium – but the creditor's domestic judgment carries no automatic force there. Converting that judgment into enforceable Belgian process requires navigating a distinct body of civil procedure rules, multilateral instruments, and, in some cases, full court proceedings before the Tribunal de première instance (Court of First Instance). The procedure is manageable, but the margin for documentary error is narrow.
Enforcing a foreign judgment in Belgium requires either direct recognition under an applicable EU regulation or treaty. Or. where no such instrument applies. formal exequatur (recognition and enforcement order) proceedings before a Belgian Court of First Instance. The core conditions are: final and enforceable status of the original judgment, proper service on the defendant, absence of conflict with Belgian public policy, and no irreconcilable prior Belgian ruling. The procedure can take from a few weeks under EU mechanisms to more than a year in contested exequatur proceedings.
This guide covers the step-by-step procedure, documentary requirements, cost considerations, common errors made by international creditors, and a decision checklist to identify the correct enforcement path for your specific situation.
The legal basis for enforcement: which instrument governs your case
The first question in any Belgian enforcement matter is which legal instrument governs. The answer determines procedure, timelines, and documentary requirements. Three distinct regimes apply, and they are not interchangeable.
EU regulations. For judgments issued within EU member states, several EU civil procedure instruments provide direct enforcement mechanisms. These cover civil and commercial matters broadly, family and matrimonial property disputes, and insolvency-related claims. Under these instruments, the enforcing party typically presents the judgment together with a standard certificate issued by the court of origin. Belgian courts do not conduct a substantive review. The process is primarily administrative once documents are in order.
A non-obvious risk here is territorial scope. Not every civil judgment from an EU state automatically falls within these regulations. Judgments in tax matters, customs proceedings, and certain administrative decisions are excluded. Practitioners in Belgium confirm that misclassifying the subject matter of the original judgment is one of the most frequent early errors by international creditors.
Bilateral and multilateral treaties. Belgium has concluded bilateral enforcement treaties with several non-EU states. These treaties set their own recognition conditions – which may be narrower or broader than the EU regime. Where a treaty applies, its provisions govern. Identifying the applicable treaty requires verification against Belgium's international instruments currently in force.
Common law exequatur under Belgian civil procedure rules. Where no EU regulation or treaty applies. most commonly for judgments from the United States. The United Kingdom post-Brexit. Alternatively, other third-country jurisdictions. the creditor must bring exequatur proceedings. The Belgian Court of First Instance conducts a structured review. It does not re-examine the merits of the dispute, but it does verify a defined set of procedural and substantive conditions under Belgian private international law and civil procedure rules.
For cross-border matters also involving corporate disputes in Belgium, the choice of enforcement path often intersects with questions of jurisdiction and parallel proceedings. Identifying the correct instrument at the outset avoids wasted time and cost.
Step-by-step procedure for exequatur proceedings in Belgium
Where EU regulations or treaties do not apply, the creditor must follow the common law exequatur route. The stages below reflect the standard procedure under Belgian civil procedure rules.
Step 1: Verify enforceability of the foreign judgment (weeks 1–2). Confirm that the judgment is final and enforceable in the jurisdiction where it was issued. A judgment under appeal, or not yet final under the law of the issuing state, cannot be presented for exequatur. Obtain a certificate of finality from the issuing court if available.
Step 2: Gather and authenticate documents (weeks 2–5). The documentary package for exequatur proceedings typically includes:
- A certified copy of the original judgment, bearing the official seal of the issuing court
- A sworn translation into French, Dutch, or German – the three official languages of Belgium
- Proof that the judgment is final and enforceable in the jurisdiction of origin
- Evidence that the defendant was properly served in the original proceedings
- Any appellate decisions affecting the judgment
Authentication requirements depend on the country of origin. Many states require an apostille (a legalisation certificate under the Hague Convention on apostille) on judicial documents. States not party to that convention require full diplomatic legalisation, which adds several weeks and additional cost. A common mistake is assuming that a notarised copy suffices; Belgian courts require court-certified copies, not notarial attestations of the original.
Step 3: File the application with the Court of First Instance (week 5–6). The application is addressed to the president of the Court of First Instance in the district where the debtor is domiciled. Alternatively. Where enforcement assets are located. The application is made by way of a requête unilatérale (unilateral petition) in the first instance – that is, without automatic notification to the debtor at this stage. Belgian civil procedure rules allow for this ex parte approach where the creditor needs to prevent asset dissipation.
Step 4: Court review (weeks 6–14 for uncontested matters). The court examines the following conditions under Belgian private international law:
- The foreign court had proper jurisdiction under Belgian private international law standards
- The judgment does not conflict with Belgian public policy (ordre public)
- The judgment is not irreconcilable with a prior Belgian judgment or a prior judgment from a third state recognised in Belgium
- The defendant was not deprived of the right to a fair hearing in the original proceedings
- The judgment was not obtained by fraud
The public policy condition deserves particular attention. Belgian courts construe this narrowly – they do not refuse enforcement simply because Belgian law would have produced a different result. Enforcement is refused on public policy grounds only where the foreign judgment produces an outcome that would be manifestly incompatible with fundamental Belgian legal principles. Punitive damages awards from common law jurisdictions are one area where this condition is regularly contested. Courts in Belgium have, in practice, granted partial exequatur – recognising compensatory damages while refusing to extend enforcement to the punitive component.
Step 5: Obtaining the exequatur order and enforcement (weeks 14 onwards). If the court grants the exequatur, the order renders the foreign judgment enforceable throughout Belgian territory. The creditor then instructs a Belgian bailiff (huissier de justice) to serve the order and execute enforcement measures – attachment of bank accounts, seizure of movable assets, or registration of a charge on immovable property.
If the respondent challenges the exequatur at this stage or files opposition after service, the matter moves to a contradictory hearing. This can extend the overall timeline to twelve months or beyond, depending on the complexity of the grounds raised.

Enforcing foreign arbitral awards: the New York Convention route
Foreign arbitral awards follow a different path from court judgments. Belgium is a contracting state to the Convention on the Recognition and Enforcement of Foreign Arbitral Awards (New York Convention), which provides the primary international instrument for award enforcement.
Under the New York Convention framework, a creditor seeking to enforce a foreign arbitral award in Belgium presents the award and the arbitration agreement to the Court of First Instance. Together with certified copies and translations. The court applies the Convention's limited grounds for refusal, which mirror – but are not identical to – the exequatur conditions for court judgments.
The seat of arbitration matters significantly here. An award issued at a seat in an EU member state may also benefit from certain EU civil procedure instruments. An award from a non-Convention country falls entirely outside the New York Convention mechanism and must rely on Belgian arbitration legislation directly.
Where the award was rendered under ICC Rules (International Chamber of Commerce Rules) or UNCITRAL (United Nations Commission on International Trade Law) rules, practitioners generally find the documentary record well-organised, which facilitates the enforcement application. The arbitral tribunal's written reasons, the signed award, and the arbitration agreement are typically already available in authenticated form.
A non-obvious risk specific to award enforcement: Belgian arbitration legislation permits a challenge to an award's enforceability on the basis that the arbitral tribunal exceeded its mandate. This ground is raised more often than creditors expect when the award covers multiple claims, some of which fell outside the scope of the arbitration clause. Reviewing the original arbitration agreement against the scope of the award before filing is essential.

Self-assessment checklist before initiating enforcement in Belgium
This checklist is designed to help creditors identify the correct enforcement path and assess readiness before incurring procedural costs.
Determine the applicable instrument:
- Is the judgment from an EU member state in a civil or commercial matter? If yes, identify the applicable EU civil procedure regulation.
- Does a bilateral enforcement treaty between Belgium and the judgment state exist and remain in force? If yes, apply its conditions.
- If neither applies, prepare for full exequatur proceedings under Belgian private international law.
Verify the judgment's status in its home jurisdiction:
- Is the judgment final and no longer subject to ordinary appeal?
- Is it currently enforceable in the state where it was issued?
- Has it been partially satisfied already? Document the outstanding balance.
Check documentary readiness:
- Do you have a court-certified copy of the judgment – not a notarised copy?
- Has the document been apostilled or diplomatically legalised as required?
- Is a sworn translation into French, Dutch, or German available?
- Can you produce evidence of proper service on the defendant in the original proceedings?
Assess enforcement risks:
- Does the judgment include punitive or exemplary damages? If yes, seek advice on whether partial exequatur is more realistic.
- Is there a parallel Belgian proceeding or a prior Belgian judgment on the same dispute?
- Does the debtor have identifiable assets in Belgium? Enforcement without traceable assets produces no practical result.
Scenario guidance:
- EU judgment, uncontested debt, identifiable assets: Fast-track EU regulation route. Timeline measured in weeks.
- US or UK judgment, commercial dispute, solvent Belgian debtor: Full exequatur proceedings required. Budget six to twelve months and legal fees in the thousands of euros range.
- Foreign arbitral award, New York Convention state, ICC or UNCITRAL award: New York Convention enforcement before the Court of First Instance. Documentary preparation is the critical path item.

Frequently asked questions
Q: How long does it take to enforce a foreign judgment in Belgium?
A: The timeline depends on the legal basis for enforcement. Under EU regulation mechanisms, recognition can be established relatively quickly once documents are in order – often within a few weeks for straightforward cases. Where full exequatur proceedings are required before the Court of First Instance, the process typically runs from several months to over a year, depending on court scheduling and whether the respondent raises opposition.
Q: Does Belgium require a review of the foreign court's substantive findings before enforcing a judgment?
A: No. A common misconception is that Belgian courts re-examine the merits of the original dispute. They do not. Belgian civil procedure rules prohibit a review of the substance of the foreign judgment. The court examines only procedural regularity, public policy compatibility, and whether the jurisdictional and documentary conditions are satisfied.
Q: Can a foreign arbitral award be enforced in Belgium under the same procedure as a court judgment?
A: No. Foreign arbitral awards follow a separate enforcement path governed by Belgium's arbitration legislation and the New York Convention framework, which Belgium has adopted. The exequatur for an arbitral award is sought before the Court of First Instance, but the applicable conditions differ from those for court judgments. Engaging a lawyer in Belgium with cross-border arbitration experience is essential to identify which route applies and to prepare the correct documentation.
