Are prenuptial agreements legally binding in England?

Prenups are not automatically binding under English law but are 'decisive weight' post-Radmacher if: freely entered with full financial disclosure, both parties received legal advice, no duress, and if fair to hold the parties to it at the time of the proceedings (Radmacher [2010] UKSC 42).

What invalidates a prenuptial agreement?

Invalidating factors: short time between signing and wedding (under 28 days is very risky); non-disclosure of assets; no independent legal advice; provisions for children that override court discretion; and changed circumstances making enforcement manifestly unfair.
