Lugano Convention: How to Enforce an EU/EFTA Commercial Judgment in Switzerland

Last updated: September 2026 (review for new Lugano guidance annually)

To enforce EU judgment Switzerland has developed one of the most predictable cross-border regimes in Europe, anchored in the Lugano Convention that binds Switzerland to the recognition and enforcement framework shared with the European Union and its EFTA partners. As 2026 sharpens practitioner attention on jurisdiction and enforcement mechanics between Switzerland and the EU/EFTA bloc, creditors and in-house counsel need a clear, Switzerland-focused playbook rather than a generic overview. This guide explains when the Lugano Convention applies, sets out a step-by-step Swiss enforcement procedure, and covers timelines, costs, tactical defences and the interplay with Swiss asset attachment.

It covers civil and commercial money judgments from EU member states, Norway and Iceland, and deliberately excludes several categories such as bankruptcy, arbitration and certain family and succession matters, which follow separate rules.

How the Lugano Convention Governs Recognition and Enforcement in Switzerland

The Lugano Convention on jurisdiction and the recognition and enforcement of judgments in civil and commercial matters is the central instrument that determines how you enforce EU judgment Switzerland courts will accept. The version currently in force for Switzerland is the 2007 Lugano Convention, which entered into force for Switzerland on 1 January 2011. It broadly parallels the EU regime that governs the circulation of judgments within the Union (historically the Brussels I Regulation), and it extends comparable treatment to Switzerland, Norway and Iceland alongside the EU member states. Its purpose is straightforward but commercially significant: to allow a judgment obtained in one contracting state to be recognised and enforced in another without a full re-examination of the merits.

For a creditor, the practical effect is that a money judgment from, say, a German, French or Italian commercial court is not treated as a foreign object to be litigated afresh in Switzerland. Instead, the Swiss courts apply the streamlined framework of the Convention, examining only a narrow set of grounds before allowing enforcement to proceed. This reduces cost, uncertainty and delay compared with the position for judgments from states outside the Lugano and EU network.

Switzerland is a full contracting party to the Convention, and the Swiss Federal Office of Justice provides official guidance on how the instrument operates alongside domestic law. The treaty text and the list of contracting states are maintained through official intergovernmental channels, and practitioners should always check the current position before relying on the regime for a specific counterparty. Note that, within the EU, the 2007 Lugano Convention has in intra-EU relations been superseded by the recast Brussels I Regulation (Regulation (EU) No 1215/2012); Lugano remains the governing instrument for the Switzerland–EU/EFTA relationship.

Which Judgments Are Covered (Civil and Commercial)

The Convention applies to judgments in civil and commercial matters, whatever the nature of the court that gave them. This captures the vast majority of commercial disputes: breach of contract, unpaid invoices, damages awards, supply and distribution disputes, and similar money and performance obligations. It excludes revenue, customs and administrative matters, as well as several carved-out categories such as the status and legal capacity of natural persons, rights in property arising out of a matrimonial relationship, wills and succession, bankruptcy and analogous insolvency proceedings, social security and arbitration. For a typical creditor pursuing a commercial debt, the judgment will fall squarely within scope, but counsel should confirm the subject matter before proceeding.

Which States Are Contracting Parties (EU, Norway, Iceland, Switzerland)

The Lugano regime binds the European Union, and therefore judgments emanating from courts in EU member states, together with Switzerland, Norway and Iceland. This is the network that makes it possible to enforce EU judgment Switzerland-side under the simplified procedure. A judgment from a court in a state outside this network falls back on Swiss domestic private international law rather than the Convention. Because contracting-state status can evolve, and because the relationship between the various instruments has attracted renewed attention in 2026, verifying the current standing of the originating state is a necessary first step in any enforcement strategy.

When Lugano Applies Versus Swiss Domestic Private International Law (PILA)

The threshold question in every case is whether the Lugano Convention or Swiss domestic law governs the recognition and enforcement of the judgment. Where the judgment comes from a contracting state and concerns a civil or commercial matter within scope, the Convention applies and takes precedence over the general regime of the Swiss Federal Act on Private International Law (PILA). Where the judgment comes from a state outside the Lugano and EU network, PILA, together with any applicable bilateral treaty or reciprocity arrangement, provides the governing framework.

This distinction matters because the two routes differ substantially in ease, speed and the breadth of available defences. Under the Convention, the reviewing court is confined to a short list of refusal grounds and cannot reopen the merits. Under PILA, the recognition analysis, while still not a full merits rehearing, involves a broader set of formal and jurisdictional checks and, in practice, tends to be more evidentially demanding. A creditor who understands early which route applies can prepare the correct dossier and set realistic expectations on cost and timing.

The applicability test is practical rather than theoretical. Counsel should confirm three points: first, that the originating court sits in a Lugano contracting state; second, that the subject matter is civil or commercial and not within an excluded category; and third, that the decision is a judgment capable of recognition, an enforceable decision rather than an interim ruling with no cross-border effect. If all three hold, the streamlined Convention route is available.

Overlap and Interaction with PILA

Even where the Lugano Convention governs recognition and enforcement, PILA remains relevant at the margins and continues to fill gaps the Convention does not address. PILA supplies the general Swiss statutory backdrop for international private-law questions and applies in full to judgments from non-contracting states. In Lugano cases, domestic procedural law, including the rules on which authority has competence and how proceedings are conducted, continues to operate alongside the Convention, which sets the substantive recognition standard but leaves much of the procedural machinery to national law. In short, the Convention determines whether a judgment is recognised and enforced, while Swiss domestic law determines much of how the process runs on the ground.

Getting both layers right is essential to a smooth enforcement.

Recognition Versus Enforcement, Legal Tests and Effects

It is important to distinguish recognition from enforcement, because the two concepts serve different functions even though they often travel together. Recognition is declaratory: it means that the Swiss legal order accepts the foreign judgment as producing the legal effects it has in its state of origin, for example, that a debt has been conclusively established, or that a matter is res judicata and cannot be re-litigated. Enforcement is executory: it means that the creditor can invoke the coercive machinery of the Swiss state, seizure, attachment and realisation of assets through the debt-collection system, to obtain actual satisfaction.

Under the Lugano framework, a judgment given in a contracting state and enforceable there is, in principle, enforceable in Switzerland once the applicable formalities are met. The reviewing court does not sit as a court of appeal and cannot re-examine the substance of the dispute. This prohibition on merits review is the central protection the Convention offers a judgment creditor: the debtor cannot use Swiss enforcement proceedings as a second bite at the underlying case. The court’s role is confined to checking the limited refusal grounds.

Those grounds are deliberately narrow. Recognition may be refused principally where it would be manifestly contrary to Swiss public policy, where the judgment was given in default and the defendant was not served with the document instituting proceedings in sufficient time and in such a way to arrange a defence, where the judgment is irreconcilable with a judgment given between the same parties in Switzerland, or where certain jurisdictional protections, for instance in insurance or consumer matters, were not respected. Outside these categories, the debtor has little room to resist.

Defences Commonly Raised in Switzerland

In practice, debtors resisting enforcement in Switzerland tend to cluster their arguments around a handful of themes. The most frequently invoked is public policy, though Swiss courts apply it restrictively and reserve it for outcomes that would offend fundamental principles of the Swiss legal order rather than mere disagreement with the foreign result. A second common line is procedural: an allegation that the debtor was not validly served with the originating process, particularly in default judgments, or that documents required under the Convention are missing or defective. A third is irreconcilability with an existing Swiss judgment between the same parties. Debtors may also raise set-off, insolvency or third-party claims to complicate realisation.

Because these defences are narrow and heavily fact-dependent, a well-prepared dossier that anticipates them substantially reduces the risk of delay.

Step-by-Step Procedure to Enforce EU Judgment Switzerland Courts Will Accept

The procedural route to enforce EU judgment Switzerland recognises begins with assembling a complete and correctly authenticated dossier, filing before the competent cantonal authority, and then converting recognition into practical recovery through the Swiss debt-collection and enforcement system. The Convention keeps the recognition stage streamlined, but Swiss procedure demands precision on documents, translations and competence. The sequence below reflects how experienced practitioners approach a commercial enforcement.

Document Checklist (What to Submit)

A well-prepared application is the single most effective way to keep an enforcement on track. The core dossier typically comprises:

• An authenticated copy of the judgment. A copy of the decision from the originating court that satisfies the conditions necessary to establish its authenticity.
• The Convention certificate. A certificate issued by the court or competent authority of the state of origin, in the standard form contemplated by the Lugano Convention (its Annex V), confirming details of the judgment.
• Proof of service. Where the judgment was given in default, evidence that the defaulting party was served with the document instituting proceedings, or an equivalent document.
• Certified translations. Translations into the official language of the relevant canton (German, French or Italian) where the court requires them.
• Evidence of enforceability. Documentation confirming the judgment is enforceable in the state of origin.

Missing or defective documents are the most common cause of avoidable delay, so verifying the bundle against the Convention’s requirements before filing is time well spent.

Which Swiss Court to File In (Competent Cantonal First Instance)

Switzerland is a federal state, and enforcement proceedings are handled at cantonal level rather than by a single national court. The application for a declaration of enforceability, and the subsequent execution measures, are directed to the competent authority in the canton where the debtor is domiciled or where the assets to be seized are located. Identifying the correct canton early is important because it determines the applicable procedural rules, the language of proceedings and the fee schedule. Where a debtor has assets spread across several cantons, a creditor may need to coordinate parallel steps. Local procedural knowledge is valuable here, since cantonal practice can differ in points of detail even though the substantive Convention standard is uniform.

Timeline and Typical Durations

One of the principal attractions of the Lugano route is speed. Because the reviewing court does not re-examine the merits, the recognition and declaration-of-enforceability stage can be relatively swift where the dossier is complete, often a matter of a few weeks to a few months at first instance. If the debtor lodges an appeal against the declaration of enforceability, or raises one of the limited refusal grounds, the timeline extends accordingly, potentially by several months. The subsequent execution phase, in which the creditor pursues seizure and realisation through the debt-collection system, adds further time that depends on the nature and liquidity of the assets.

Realistic planning assumes a straightforward case resolves within months rather than weeks, while a contested one should be budgeted as a longer engagement.

Costs, Court Fees and Typical Lawyer Fees

Court fees for recognition and enforcement in Switzerland vary by canton according to local tariffs and, in some cases, the amount in dispute. They are typically a modest fraction of the sums at stake in a commercial matter. Lawyer fees are the larger and more variable component: they depend on the complexity of the dossier, whether the debtor contests recognition, the number of cantons involved, and whether urgent asset preservation is required in parallel. Straightforward, uncontested enforcements can often be handled economically, sometimes on a fixed-fee or capped basis, whereas contested proceedings with appeals and asset-tracing are charged on a time basis.

Even so, enforcement in Switzerland under the Lugano framework is frequently more cost-effective than attempting recovery through less predictable foreign systems, particularly where the debtor holds identifiable Swiss assets.

Interim Relief and Asset Preservation, Arrest (Attachment) in Switzerland

A judgment is only as valuable as the assets available to satisfy it, and debtors facing enforcement have an obvious incentive to move funds beyond reach. Swiss law addresses this risk through the arrest (attachment) procedure under the Federal Debt Enforcement and Bankruptcy Act (DEBA), a fast, provisional measure that allows a creditor to freeze a debtor’s Swiss-situated assets, most commonly bank accounts, before the debtor can dissipate them. For anyone seeking to enforce EU judgment Switzerland recognises, arrest is the tactical companion to the recognition process: it secures the target while the enforcement machinery runs its course.

Arrest is granted by the competent cantonal court on the creditor’s application, typically without prior notice to the debtor so as to preserve the element of surprise. The creditor must show a valid claim, identifiable assets in Switzerland and a recognised ground for arrest. Under the DEBA, the existence of a definitive enforceable title, including a judgment from a Lugano contracting state that is enforceable in Switzerland, is itself an express ground for arrest, which provides a particularly strong footing for the application. Once the arrest is granted and executed by the debt-collection office, the assets are frozen pending the creditor’s continuation of enforcement.

Because arrest is provisional and obtained ex parte, the debtor can subsequently object and seek to have it set aside, so the initial application must be carefully documented. The interplay between arrest and Lugano enforcement is where much of the practical value lies: securing assets first, then converting the title into execution, is often the difference between a paper victory and actual recovery.

How to Use Arrest Before or After Recognition

Timing is a strategic choice. Where speed and secrecy are paramount, for example, where there is reason to fear imminent dissipation, a creditor may seek arrest at the outset, in parallel with or even ahead of the formal recognition application, relying on the enforceable foreign title to ground the request. Where the debtor is unaware and assets are stable, a creditor may prefer to obtain the declaration of enforceability first and then proceed to execution. In many commercial recoveries the two tracks are run together: the arrest freezes the target while the recognition proceeding delivers the enforceable Swiss title needed to realise it. Coordinating the two requires local counsel who can move quickly when the moment demands it.

Common Tactical Issues and Defences

Beyond the formal refusal grounds, several practical issues recur in commercial enforcement and reward advance planning. A debtor may attempt to challenge the jurisdiction of the originating court, though under the Lugano framework the Swiss court is generally bound to accept the jurisdiction findings of the court of origin, save in the specific protected categories. Set-off claims and counterclaims can complicate the execution phase, as can insolvency of the debtor, which may divert the matter into collective proceedings and alter the creditor’s ranking. Third-party claims to arrested assets, for instance, assertions that funds in a frozen account belong to another entity, are a familiar obstacle where corporate structures are opaque.

Enforcement against corporate groups raises its own difficulties. A judgment against one company in a group does not automatically reach the assets of affiliates, and creditors must be realistic about identifying the entity that actually holds recoverable value. Where the debtor structure is layered, asset tracing and careful targeting of the arrest are decisive. Public-policy challenges will occasionally be mounted, but Swiss courts construe the exception narrowly, and a creditor should not be deterred by the mere prospect of one.

Enforcement Against Swiss-Based Assets Versus Foreign Assets Located in Switzerland

The Swiss enforcement machinery reaches assets physically or legally situated in Switzerland, Swiss bank accounts, real property, shares in Swiss companies and receivables owed by Swiss debtors. Assets held abroad, even by a Swiss-domiciled debtor, generally fall outside the direct reach of Swiss execution and require enforcement in the relevant foreign jurisdiction. In practice, the most productive targets are liquid Swiss-based assets such as bank balances, which arrest can freeze quickly. Identifying where value actually sits, and confirming it is genuinely within Swiss enforcement reach, should precede any application.

The contrast between the Lugano route and the domestic PILA route is stark enough to shape strategy from the outset. The table below summarises the key differences a creditor should weigh when deciding how to proceed.

Practical Next Steps for In-House Counsel and Creditors

When you need to enforce EU judgment Switzerland offers a fast route, but preparation determines the outcome. Before filing, take the following practical steps:

• Confirm the route. Verify that the originating state is a Lugano contracting state and that the subject matter is civil or commercial and within scope.
• Assemble the dossier. Obtain the authenticated judgment, the Convention certificate, proof of service and certified translations into the relevant cantonal language.
• Locate the assets. Identify recoverable Swiss-situated assets and the canton in which they sit, focusing on liquid targets such as bank accounts.
• Assess urgency. Where dissipation is a risk, prepare an arrest application to run in parallel with recognition, and be ready to act ex parte.
• Budget realistically. Factor in cantonal court fees and variable lawyer fees, and weigh the cost-effectiveness of Swiss enforcement against alternative jurisdictions.
• Engage local counsel early. Cantonal procedural knowledge and the ability to move quickly on arrest are frequently decisive.

Conclusion

For creditors and in-house counsel, the ability to enforce EU judgment Switzerland provides through the Lugano Convention is a genuine commercial advantage: a streamlined recognition standard, a prohibition on re-litigating the merits, narrow refusal grounds and a fast, powerful arrest procedure to secure assets. Success turns on getting the fundamentals right, confirming that the Convention applies, assembling a complete and correctly translated dossier, filing before the competent cantonal court, and coordinating asset preservation where dissipation is a risk. Handled with local knowledge and early preparation, enforcement in Switzerland is frequently quicker and more cost-effective than the alternatives, turning a foreign judgment into real recovery.
