Cross-border enforcement

Enforcing a Switzerland judgment in United Kingdom

Switzerland is not a party to the 2019 Hague Judgments Convention, and the UK lost its access to the Lugano Convention after leaving the EU. No treaty connects this pair. A Swiss judgment reaches the UK only through a fresh action that treats the judgment as a debt, with no registration procedure and no automatic recognition available.

Applicable regime

Switzerland does not appear among the contracting parties to the 2019 Hague Judgments Convention, which entered into force on 1 September 2023. That absence means the convention is irrelevant to this pair regardless of when a claim was filed. The UK's own Hague 2019 route applies from 1 July 2025 onward, but only between contracting parties, and Switzerland is not one.

Separately, Switzerland's main treaty route with EU and EFTA states runs through the Lugano Convention rather than Brussels Ia. That route does not extend to the UK either: after leaving the EU, the UK lost its access to both Brussels Ia and Lugano. With every treaty route closed, what remains is a fresh action in England and Wales that treats the Swiss judgment as evidence of a debt rather than as an order the court simply registers. The UK jurisdiction profile sets out how that sits alongside the routes available for other origins into the UK, summarised here.

What the destination court will check

Because there is no treaty base, the destination court is not applying treaty conditions. It is examining an ordinary civil claim for a fixed sum, where the Swiss judgment supplies the evidential basis for that sum.

The elements a claimant needs are cumulative. All of them must be met together; none stands alone.

• A Swiss judgment that finally disposes of the underlying claim between the same parties.
• A sum that is fixed or readily calculable, rather than an order for something else.
• A fresh claim brought in England and Wales, rather than an application to register the foreign order.

Further points the court may examine depend on the specific judgment and any defence raised. That assessment is made from the file, not a general checklist. A cross-border recognition and enforcement engagement starts from that file.

What will not go through

A judgment ordering something other than payment of a sum, such as an injunction or a declaration, does not travel through this route. The fresh action is built around a debt, and there is nothing else for it to attach to.

Two assumptions cause the most damage here. One is that the Hague Judgments Convention 2019 covers this pair because the UK is a contracting party. It does not, because Switzerland is not on the list of parties to that convention. The other is that the Lugano Convention still connects the UK and Switzerland after Brexit. It does not; UK access to Lugano ended with its EU membership. A filing built on either assumption rests on a route that is not open. Enforcement running the other way, from a UK judgment into Switzerland, follows a different regime and is not simply this page in reverse.

Documents

Switzerland and the UK are both parties to the 1961 Apostille Convention. The UK's accession has been in force since 24 January 1965, and ordinary civil judgments fall within its scope. A Swiss judgment used in an English proceeding needs an apostille from the competent Swiss authority rather than consular legalisation, together with a certified English translation where the original is in French, German or Italian.

Timing

A common law claim on a foreign judgment debt in England and Wales runs against a six-year limitation period, counted from the date the Swiss judgment became enforceable in Switzerland rather than the date it was handed down, if the two dates differ.

Filing carries a fee set on the money-claim scale, capped at 10,000 GBP for claims valued above 200,000 GBP. Enforcement steps such as a writ or warrant of control carry their own fixed fees on top of the claim fee. How this six-year period interacts with limitation rules in other jurisdictions is addressed separately.

If the primary route is closed

If the six-year window has already closed on the underlying claim, a judgment debt can sometimes still be pursued through bankruptcy or liquidation proceedings against the debtor, where the ordinary limitation rule for a fresh action does not apply in the same way.

For disputes not yet decided, an arbitration clause pointing to a seat in a New York Convention state changes the enforcement map. An arbitral award, unlike a Swiss court judgment, is tested under that convention on non-enforcement of an arbitral award, which has wider reach than any single judgment-recognition treaty. Enforcement problems originating in Switzerland follow different rules depending on whether the underlying instrument is a judgment or an award.

What to do before filing

Before filing, check what is actually reachable in the UK: bank accounts, property, receivables owed by UK counterparties. A judgment against a debtor with no assets in reach is a cost rather than a recovery step.

Whether an interim measure can freeze assets while the claim proceeds is established from the file rather than from a general rule for this pair. Evidence of dissipation risk is worth assembling before filing rather than after it; a checklist for that evidence exists for non-enforcement cases.
