Prenup & Marriage Contract Navigator

Prenup: United States + Kazakhstan

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

Which contract, and where to sign 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.

Kazakhstan: Notarial form; before or during the marriage — on a model close to the Russian one.

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

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

Kazakhstan: Property matters (Arts. 39–43 of the Marriage and Family Code); unlike Russia, terms on the children’s property position are allowed (Art. 41(1)) — personal matters and custody stay outside the contract.

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”.

United States: State-dependent: some states require separate consideration and scrutinise postnups harder than prenups. Kazakhstan: Can be concluded during the marriage with the same force.

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