Prenup & Marriage Contract Navigator

Prenup: Russia + United States

Case complexity: medium. The contract has to work across several legal systems at once: Russia, United States.

Which contract, and where to sign it

Russia: Notarial form only; concluded before the marriage (effective from registration) or at any point during it.

United States: Written and signed; there is no uniform standard — the UPAA/UPMAA are adopted by most but not all states (New York, Massachusetts, Ohio and others follow their own law): voluntariness, full disclosure and time to reflect are required almost everywhere.

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

The Russian layer: spouses without common citizenship or residence may choose the law applicable to their marriage contract (Art. 161 Family Code) — a rare and useful option for mixed couples.

English and US courts will judge the contract by their own rules whatever law it names — for these jurisdictions the signing procedure decides, not the choice-of-law clause.

What you can fix in it

Russia: Property matters only: the regime, specific assets, stakes, compensation. Personal relations and children cannot be regulated; terms leaving a spouse in an extremely unfavourable position will be struck down (Arts. 42(3), 44(2) Family Code).

United States: Assets and alimony (waivable in many states absent unconscionability); child support and custody cannot be locked in.

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.

What to watch out for

Several legal systems mean a package, not one text: an anchor contract + mirrors + local opinions.

Russia: lopsided terms risk falling under Art. 44 — build in balance, not “everything to one side”.

Can the contract be signed after the wedding (postnup)?

Russia: A postnup is the same notarial contract concluded during the marriage, with full force. Bonus for mixed couples: absent common citizenship or residence the spouses may choose the law applicable to the contract (Art. 161 Family Code). United States: State-dependent: some states require separate consideration and scrutinise postnups harder than prenups.

This is a first-pass orientation, not legal advice. The rules are simplified; the contract itself is drafted by a lawyer for your couple.
