Prenup: Cyprus + Switzerland

Which contract, and where to sign it

Cyprus: No dedicated statute: a marriage contract is an ordinary contract; written form and certification are essential in practice but confer no privileged status.

Switzerland: A notarial deed (öffentliche Beurkundung); concluded before or at any point during the marriage.

Several legal systems are involved — one document will not cover them all. The working construction: an anchor contract in the principal jurisdiction plus mirror texts where the key assets sit, backed by local counsel opinions.

Choice of applicable law

In the EU, fix the choice of law inside the contract (Regulation 2016/1103): the law of either spouse’s citizenship or habitual residence. Without a choice, the regime follows the first common residence — and migrates with you unpredictably.

What you can fix in it

Cyprus: A court may take the contract into account in a contribution claim (Law 232/1991) but is not bound by it.

Switzerland: Election among the statutory regimes (separation, community) and adjustment of accrual shares; the statute sets the frame — freeform constructions fail.

What gives the contract its force

Full asset disclosure annexed to the contract — the main anchor against future challenge.

Independent counsel for each side; one adviser for both is the classic line of attack.

Translations and legalisation: every version with a notarised translation and apostille for its jurisdiction of use.
