A postnuptial agreement records how a married couple wants their finances and assets treated if the marriage later ends — signed after the wedding, unlike a prenup.
What this postnuptial agreement covers

- Intentions for how assets are treated on separation
- Provision for children
- Independent legal advice confirmation
When you need a postnuptial agreement
- Marrying without a prenup and wanting to formalise arrangements after the wedding
- A significant change in circumstances — inheritance, a new business, a house purchase
- Wanting clarity and reduced conflict if the marriage were ever to end
The legal framework
Understanding the law behind a postnuptial agreement helps you use it well. Here is the key UK legislation that applies:
Frequently asked questions
Is a postnuptial agreement legally binding in the UK?
Not automatically — but UK courts give significant weight to a fair agreement entered into freely, with full financial disclosure and independent legal advice for both spouses.
What's the difference between a prenup and a postnup?
A prenup is signed before marriage, a postnup after. Postnups can sometimes be viewed even more favourably by courts, since there's no argument that a spouse felt pressured to sign before a wedding that was already planned.
