Cross-border enforcement

Enforcing a United States judgment in Switzerland

There is no treaty between the United States and Switzerland covering recognition of civil judgments. The Hague 2019 Convention does not close that gap. The US signed it without ratifying, and Switzerland never joined at all. A US judgment reaches Switzerland only through Swiss domestic recognition, unless the underlying claim was arbitrated instead. See non-enforcement as a refusal type for the broader pattern this fits into.

Applicable regime

The Hague Judgments Convention 2019 entered into force on 1 September 2023 and currently binds seven contracting parties covering 32 states, since the EU's accession draws in 26 member states apart from Denmark (N001, N002). The United States signed the convention on 2 March 2022 but has not ratified it, so it carries no obligation toward any other state under this instrument (N011, N170). Switzerland has not signed or ratified the convention at all; it is absent from the list of contracting parties (N131). Neither gap cures the other. Full US ratification would still not bind Switzerland, and the reverse holds too. For judgments leaving the United States toward a Hague 2019 state, the treaty analysis is different from this pair. Here it is closed on both ends, so the claim moves through Swiss national recognition law unless it was arbitrated. Arbitral awards run on a separate track under the 1958 New York Convention, generally considered more dependable than the court-judgment route between these two states (N016, N172).

What the destination court will check

Without a treaty, a Swiss court examining a US judgment applies its own private international law test to the merits. The conditions are cumulative. All must be met; satisfying only one is not sufficient.

• The US court that rendered the judgment must have had a basis of jurisdiction that Swiss law would also treat as adequate.
• The judgment must be final under the law of the state where it was rendered, with no ordinary appeal still open.
• The defendant must have been properly summoned and given a genuine opportunity to respond.
• Recognition must not conflict with a decision already given, or pending, in Switzerland on the same matter.
• Enforcement must not offend Swiss public policy.

These are general recognition criteria, not a Swiss statute reproduced here; no specific article number is cited because none appears in the verified registry for this page. A Switzerland jurisdiction profile sets out the wider domestic framework separately.

What will not go through

Nothing routes through the Hague 2019 Convention here, whatever the subject matter, because Switzerland was never a party to it (N131). That closes the entire treaty track for tax, customs and administrative matters just as much as for ordinary commercial disputes, since the convention would have excluded those categories anyway wherever it did apply (N013).

A US arbitral award is a different instrument. It does not belong in this recognition track. That claim is examined under the 1958 New York Convention (N016), separate from the Swiss rules used for foreign court judgments. Treating an award as if it were a judgment, or the reverse, is a common filing error.

Direction also matters. The reverse route, enforcing a Swiss judgment in the United States, sits under different rules again and is handled on its own page: enforcing a Swiss judgment in the US. The conditions do not run the same way both directions.

Documents

Switzerland is a party to the Apostille Convention, in force there since 11 March 1973, with a reservation recorded under the convention (position 6) (N404). A US judgment and its supporting court records can generally be authenticated by apostille rather than by consular legalisation, since the United States is also an Apostille Convention member.

Translation into a Swiss official language the court will accept is handled at filing; it is a practical requirement, not one governed by a specific registry entry cited on this page. For judgments arriving in Switzerland from other origin states, the Switzerland enforcement hub collects the equivalent legalisation position pair by pair.

Timing

Once a US judgment is recognised and enforcement is sought in Switzerland, the right confirmed by that judgment is subject to a ten-year limitation period, running from the point the judgment became enforceable. Each enforcement step restarts a new ten-year period (N505). This applies to the underlying claim as recognised, not to the recognition proceeding itself, for which no separate registry-confirmed deadline appears here.

How this compares across other origin and destination pairs is tracked on the limitation periods comparison. For the arbitration alternative, whether the same ten-year rule extends to arbitral awards carries a LOW status in the registry and is not published here as a stated rule.

If the primary route is closed

Since no treaty connects the US and Switzerland for judgments, the most durable fix is decided before the dispute exists. An arbitration clause sends any future award through the 1958 New York Convention instead of through Swiss domestic recognition of a foreign judgment (N016, N172). That changes which instrument arrives in Switzerland, not merely which body hears the dispute.

For a judgment that already exists without such a clause, recognising it first in a third state that has a working treaty with both the US and Switzerland is sometimes raised as a workaround. It is not a guaranteed substitute for direct recognition. Whether a given third-state judgment would itself be recognised in Switzerland has to be tested on its own terms, not assumed.

Where the route runs instead from a treaty state, the mechanics differ enough to be handled as a separate piece of work: cross-border recognition and enforcement covers the assessment work across pairs.

What to do before filing

Before filing, check what actually stands behind the US judgment in Switzerland. A judgment recognised on paper is worth little against a debtor with no Swiss assets and no plan to acquire any.

Switzerland can require a claimant without Swiss domicile to post security for the defendant's costs, on the defendant's request (N507). Budget for that possibility before commencing, not after it is raised. Attachment of the debtor's Swiss assets is available even before recognition is final, and an application for exequatur can be filed alongside the attachment request rather than after it (N508).

Where the underlying refusal involves accounts that were moved or obscured rather than simply left unpaid, the evidentiary approach differs; one method for documenting non-performance is set out in proving non-enforcement on crypto accounts. There is no success fee for this kind of work, and the firm's registration can be checked in the public register linked in the footer.
