Prenup & Marriage Contract Navigator
Prenup: United Kingdom + United Kingdom
Case complexity: low. The contract touches a single legal system — United Kingdom.
Which contract, and where to sign it
United Kingdom: A written deed signed well in advance: the Law Commission benchmark is at least 28 days before the wedding, with independent legal advice for each side and full asset disclosure.
Choice of applicable law
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 Kingdom: Almost anything on assets, but a spouse or children cannot be left in need: needs override the contract and the court keeps the last word (s. 25 MCA 1973).
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.
Timing: sign well in advance (for England the benchmark is 28+ days before the wedding), free of eve-of-wedding pressure.

What to watch out for
England: the contract’s force equals the quality of the procedure (voluntariness, disclosure, 28 days, no unmet needs).

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