Enforcing a Swiss court judgment in France is a structured but demanding process. The legal bridge between the two countries is the Lugano Convention, which provides a streamlined recognition and enforcement mechanism for civil and commercial judgments. A creditor who holds a final Swiss judgment can apply for a declaration of enforceability - known in French as an exequatur - before a French court, without relitigating the merits of the case. This guide covers the applicable legal framework, the step-by-step procedure, realistic timelines and costs, available defences, and the strategic considerations that determine whether enforcement succeeds or stalls.
The 2007 Lugano Convention on Jurisdiction and the Recognition and Enforcement of Judgments in Civil and Commercial Matters is the primary instrument governing the enforcement of Swiss judgments in France. Both Switzerland and France are parties to this convention, and it applies to civil and commercial matters, excluding family law, insolvency, arbitration, and certain other areas.
Under the Lugano Convention, a judgment given in one contracting state must, in principle, be recognised and declared enforceable in another contracting state without any review of the substance of the dispute. The French court examining the application does not re-examine whether the Swiss court reached the correct legal or factual conclusions. This is a fundamental feature of the convention: it creates mutual trust between the judiciaries of the contracting states.
French domestic procedural law supplements the convention. The Code of Civil Procedure governs how the exequatur application is filed, which court has territorial jurisdiction, and how the enforcement order is served on the debtor. The Tribunal judiciaire is the competent court in France for exequatur applications under the Lugano Convention. Jurisdiction within France is determined by the domicile of the debtor or, if the debtor has no domicile in France, by the place where enforcement is sought.
A non-obvious requirement is that the Swiss judgment must be enforceable in Switzerland itself before it can be declared enforceable in France. A judgment that is still subject to an ordinary appeal in Switzerland, or that has been stayed pending appeal, will not satisfy this condition. Creditors should obtain a certificate of enforceability from the Swiss court or cantonal authority before filing in France.
The Lugano Convention sets out a specific list of documents that the applicant must produce. Preparing this bundle correctly is one of the most common points of failure for foreign creditors acting without local counsel.
The core documents are:
All documents in German, Italian, or Romansh must be accompanied by a certified French translation. Switzerland has four official languages, and Swiss judgments are frequently issued in German or Italian. The translation must be prepared by a sworn translator (traducteur assermenté) recognised in France. Errors or gaps in translation are a common cause of delay.
In practice, founders and creditors should consider obtaining the Annex V certificate at the time the Swiss judgment becomes final, rather than waiting until enforcement in France is needed. Retroactive requests can take several weeks and may slow the overall timeline.
The enforcement process in France under the Lugano Convention follows a defined sequence. Understanding each stage helps creditors set realistic expectations and avoid procedural errors.
The first stage is preparing and filing the application. The creditor, represented by a French lawyer (avocat), files a written application with the Tribunal judiciaire at the debtor's domicile in France. The application is accompanied by the full document bundle described above. At this initial stage, the procedure is ex parte: the debtor is not notified and does not participate. The court examines only whether the formal requirements of the Lugano Convention are met.
The second stage is the court's examination and initial decision. The judge reviews the application and, if satisfied, issues a declaration of enforceability. Under the Lugano Convention, this initial decision must be made promptly. In practice, French courts typically issue the initial exequatur order within several weeks of a complete filing, though the timeline varies by court and by the complexity of the document bundle.
The third stage is service on the debtor. Once the exequatur order is issued, it must be served on the debtor by a French bailiff (huissier de justice, now called commissaire de justice). The service triggers the debtor's right to appeal. Under the Lugano Convention, the debtor has one month from the date of service to lodge an appeal if domiciled in France, or two months if domiciled abroad. This deadline is strict and cannot be extended by agreement.
The fourth stage is the appeal period and any challenge. If the debtor does not appeal within the prescribed period, the exequatur order becomes final and the creditor can proceed to enforcement measures. If the debtor appeals, the case moves to a contradictory procedure before the Cour d'appel. The grounds for appeal are limited under the Lugano Convention and do not include a review of the merits.
The fifth stage is enforcement proper. Once the exequatur is final, the creditor holds an enforceable title in France. The creditor can then instruct a commissaire de justice to carry out enforcement measures: seizure of bank accounts, attachment of receivables, seizure of movable or immovable property, or garnishment of salary, depending on the nature of the debt and the debtor's assets.
The Lugano Convention limits the grounds on which a French court may refuse to recognise or enforce a Swiss judgment. These grounds are exhaustive and cannot be expanded by French domestic law.
Recognition may be refused if enforcement would be manifestly contrary to French public policy (ordre public). This is a narrow exception. French courts apply it sparingly and only where recognition would violate a fundamental principle of French legal order. Routine disagreement with the outcome of the Swiss proceedings does not meet this threshold.
Recognition may also be refused if the defendant was not served with the document instituting proceedings in sufficient time and in a manner that allowed preparation of a defence, and the defendant did not appear. This ground protects defendants who were effectively denied the opportunity to participate in the Swiss proceedings. A common mistake by creditors is assuming that service by post to a foreign address automatically satisfies this requirement; the method of service must comply with the rules applicable at the time of the Swiss proceedings.
Other grounds include irreconcilable conflict with a prior judgment given in France between the same parties, and irreconcilable conflict with an earlier judgment given in another state that would itself be recognised in France. A judgment cannot be recognised if it conflicts with certain mandatory jurisdiction rules of the Lugano Convention, particularly in matters of insurance, consumer contracts, and exclusive jurisdiction.
Importantly, the French court cannot review the jurisdiction of the Swiss court on general grounds. Jurisdiction review is limited to the specific categories listed in the convention. Many debtors attempt to raise substantive defences at the exequatur stage; French courts consistently reject such attempts.

The overall timeline to enforce a Swiss judgment in France depends on whether the debtor contests the exequatur and on the speed of the specific French court handling the case.
In an uncontested case, the process from filing to a final exequatur order typically takes between two and four months. This includes the time for the court to examine the application, issue the initial order, serve it on the debtor, and allow the appeal period to expire without challenge. Actual enforcement measures - seizure of assets, attachment of accounts - can begin immediately after the exequatur becomes final.
In a contested case, where the debtor appeals to the Cour d'appel, the timeline extends significantly. Appeals in French civil courts can take between twelve and twenty-four months, depending on the court's caseload and the complexity of the arguments raised. If the Cour d'appel's decision is itself challenged before the Cour de cassation, the total timeline can extend further.
Costs fall into several categories. Legal fees for a French avocat to prepare and file the exequatur application typically start from the low thousands of EUR for a straightforward case. Contested proceedings before the Cour d'appel involve substantially higher fees. Translation costs depend on the length and complexity of the Swiss judgment and supporting documents; multi-page commercial judgments in German can generate significant translation expenses. Bailiff fees for service and for enforcement measures are regulated and are generally modest relative to the overall cost of the proceedings. Court filing fees in France are low by international standards.
A scenario that creditors frequently underestimate is the cost of enforcement proper, after the exequatur is obtained. Identifying and seizing assets requires investigative steps - searches of the French land registry, bank account attachment procedures, and in some cases litigation over third-party claims to the assets. These steps add time and cost that are not reflected in the exequatur procedure itself.
Two contrasting scenarios illustrate the range of situations creditors face when seeking to enforce a Swiss judgment in France.
In the first scenario, a Swiss company holds a final judgment from the Tribunal de commerce de Genève against a French distributor for unpaid invoices. The French distributor is domiciled in Lyon, has a known bank account, and has not appealed the Swiss judgment. The Swiss company obtains the Annex V certificate promptly, instructs a French avocat to file the exequatur application, and serves the order on the debtor within weeks of the initial court decision. The debtor does not appeal. The commissaire de justice attaches the bank account within days of the exequatur becoming final. The entire process, from filing to recovery, takes approximately three to four months.
In the second scenario, a Swiss private individual holds a judgment from the Tribunal cantonal de Vaud against a French real estate developer for breach of a construction contract. The developer is contesting the Swiss judgment in Switzerland on appeal, so the judgment is not yet enforceable in Switzerland. The Swiss creditor cannot file for exequatur in France until the Swiss appeal is resolved and the judgment becomes enforceable. Once the Swiss appeal is dismissed and the Annex V certificate is obtained, the creditor files in France. The developer appeals the exequatur order, raising a public policy argument based on alleged procedural irregularities in the Swiss proceedings. The Cour d'appel dismisses the appeal after fourteen months. The creditor then pursues enforcement against the developer's French real estate assets through a separate seizure procedure. Total elapsed time from the Swiss judgment becoming final to recovery: approximately twenty-two months.
Many creditors underestimate the importance of asset tracing before initiating the exequatur process. An exequatur order is only as valuable as the assets available to satisfy it. If the debtor has transferred assets out of France or holds assets in complex corporate structures, enforcement becomes substantially more difficult and expensive. Conducting preliminary asset investigations in parallel with the exequatur application is a sound strategy.
A common mistake is failing to verify that the Swiss judgment covers all heads of claim, including interest and costs, before filing in France. French courts will enforce the judgment as issued; they will not supplement it. If the Swiss judgment does not include a specific award of interest or costs, those amounts cannot be recovered through the exequatur procedure.

What happens if the Swiss judgment is still under appeal in Switzerland?
A Swiss judgment that is subject to an ordinary appeal and has not yet been declared enforceable in Switzerland cannot be the subject of an exequatur application in France. The Lugano Convention requires that the judgment be enforceable in the state of origin before it can be declared enforceable in the state addressed. Creditors in this position must wait for the Swiss appeal to be resolved, or for the Swiss court to grant provisional enforceability notwithstanding the appeal, before proceeding in France. In practice, this means that creditors should monitor the Swiss proceedings closely and be ready to file in France promptly once enforceability is confirmed, particularly if there is a risk that the debtor may dissipate assets in the interim.
How long does the exequatur process take, and what does it cost overall?
In an uncontested case, the exequatur process from filing to a final enforceable order typically takes two to four months. If the debtor appeals, the timeline extends to twelve to twenty-four months or more. Legal fees for the exequatur application itself typically start from the low thousands of EUR, with contested proceedings generating substantially higher costs. Translation of Swiss documents into French adds further expense, particularly for lengthy commercial judgments. Creditors should budget separately for the enforcement phase after the exequatur is obtained, as asset seizure and attachment procedures involve additional bailiff and legal fees. The overall cost-benefit analysis depends heavily on the size of the judgment and the accessibility of the debtor's assets in France.
Can a debtor raise substantive defences - such as arguing the Swiss court was wrong - at the exequatur stage in France?
No. The Lugano Convention expressly prohibits the French court from reviewing the substance of the Swiss judgment. The debtor cannot argue at the exequatur stage that the Swiss court made an error of fact or law, that the evidence was wrongly assessed, or that the outcome was unfair. The only available defences are the limited grounds set out in the convention: manifest violation of French public policy, failure to serve the defendant in sufficient time to prepare a defence, irreconcilable conflict with a prior French judgment, and a small number of other specific grounds. French courts apply these grounds strictly and narrowly. Debtors who attempt to relitigate the merits of the Swiss dispute at the exequatur stage consistently fail.
Enforcing a Swiss judgment in France is achievable and, in straightforward cases, relatively efficient. The Lugano Convention provides a solid legal foundation, and French courts apply it consistently. The main variables are the enforceability status of the Swiss judgment, the quality of the document bundle, the debtor's willingness to contest, and the accessibility of assets in France. Creditors who prepare carefully and act promptly after the Swiss judgment becomes final are well positioned to recover.
