Cross-border enforcement

Enforcing a Switzerland judgment in United States

There is no treaty between Switzerland and the United States covering civil judgments. A Swiss judgment reaches US assets only through the recognition law of the state where those assets sit, not through a federal or international mechanism. A Swiss arbitral award sits on different, firmer ground, since it travels under the New York Convention instead.

Applicable regime

The Hague Judgments Convention of 2019 does not bridge this pair. The United States signed it on 2 March 2022 but has never ratified it, so the convention is not in force for the US side. Switzerland is not a party to it at all. No bilateral treaty fills that gap either.

A Swiss court judgment therefore reaches the United States through the law of whichever individual state holds the debtor's assets, not through one national regime. Which version of that law applies, and how, is organised state by state — see enforcement in the United States for how that patchwork is set up.

An arbitral award is a different case. Both Switzerland and the United States are parties to the New York Convention of 1958, and that route is structurally more reliable for this pair than the judgment route described above.

What the destination court will check

State recognition law asks broadly the same questions everywhere, even where the exact wording differs. The Swiss judgment must be final, not still open to ordinary appeal at home. It must come from a court that had proper jurisdiction over the parties. The defendant must have had notice and a real opportunity to be heard. The judgment must not conflict with the public policy of the state where enforcement is sought, and must not be a tax, penal, or purely administrative order.

These conditions are cumulative. Failing any one of them is enough for a state court to refuse recognition, which is the pattern this firm tracks as refusal type O8, non-enforcement. Which court within a given state actually hears the recognition action is itself a procedural question, and depends on the applicable state procedure rather than on one named forum.

What will not go through

A default judgment resting on defective service will not pass. A judgment covering a claim that was subject to a binding arbitration clause will not either, since the parties contracted out of court jurisdiction for that dispute before the Swiss court ever ruled. Tax assessments, customs penalties, and purely administrative rulings fall outside recognition in most states.

California is a specific trap. It never adopted the uniform statutory recognition act that most other states rely on, and stands alongside Vermont as the exception. Enforcement against assets located there follows a different procedural track than enforcement in a state that did adopt the uniform statute, and the two should not be assumed to work the same way.

Documents

Switzerland and the United States are both parties to the Hague Apostille Convention, and the US side of that route has been confirmed in force since 1981. A Swiss judgment, and the certificate supporting it, moves into the US through an apostille issued by the competent Swiss authority, not through consular legalisation.

Any document not already in English needs a certified translation before a US court will accept it. The exact format a given state court insists on for that certification is a local detail, checked against the specific court where the action is filed.

Timing

For a court judgment, the limitation period depends on which state holds the debtor's assets; there is no single federal period. New York allows the shorter of the judgment's remaining validity in Switzerland or twenty years. Delaware allows fifteen years where Switzerland sets no fixed validity period of its own. California allows the shorter of the Swiss period or ten years. In each case the clock runs from the date the Swiss judgment was rendered, not from the date enforcement is sought.

For an arbitral award, the federal limitation period is three years from the date the award was made. Courts disagree on what happens once that window closes: one line of authority still allows recognition of a later judgment that confirmed the award, another holds that state law, not the three-year federal period, controls the confirmation action instead. Which line applies depends on the circuit where the claim is filed. A wider comparison of how limitation periods run across jurisdictions in this practice sits under limitation periods for cross-border enforcement.

If the primary route is closed

If the judgment fails one of the state conditions above, for instance because service was defective, the underlying debt can sometimes be re-litigated as a fresh claim on the obligation itself, rather than pursued as a recognition action on the Swiss judgment. That is a separate filing, not a shortcut inside the same case.

If the contract behind the dispute is still live and a future disagreement is still possible, building in or invoking an arbitration clause moves that future claim onto the New York Convention track rather than the state-law patchwork described above. For a dispute the Swiss court has already decided, that door is closed retroactively.

Readers holding a US judgment that needs to reach assets in Switzerland face an entirely different set of rules, not the mirror of this page; that direction is covered under enforcing a US judgment in Switzerland. A broader index of claims moving into the United States, from origins other than Switzerland, sits under enforcement into the United States.

What to do before filing

Filing before confirming that the debtor still holds attachable assets in the United States burns through the limitation clock described above for nothing. A recognition judgment is only as useful as what it can actually reach. Court filing fees in the US are fixed amounts rather than a percentage of the claim; the exact figure is confirmed at the time of filing.

Whether a protective measure can freeze those assets before or during the recognition action depends entirely on the facts of the case and the state involved, not on a general rule either way. Filing also carries exposure of its own: a defendant can raise counterclaims, or seek costs, if the action is found to have been improperly brought.

An entry-level assessment maps what is actually recoverable before litigation starts; how this firm structures that review is described under cross-border recognition and enforcement, and the reasoning behind this refusal pattern is set out in non-enforcement as a refusal type. That assessment is charged regardless of outcome; this firm does not work on a pure contingency basis, and its registration is checked in the public registry.
