Your postnup prepared online, with your partner's own review. No solicitor included.
- Your agreement
- Your postnuptial agreement as a PDF, written by UK Prenup (not a law firm) around the tests the courts apply.
- For both of you
- Forms to list what you each own and owe; a private page where your partner reads it, adds their disclosure and asks for changes or confirms it; and a guide to signing it, each in front of a witness.
Advice for one of you. Your partner takes their own advice from a different firm.
- Your solicitor
- An independent family-law solicitor: a written advice letter, a signed certificate where they're satisfied you understand the agreement, and any changes they recommend made before you sign.
- From UK Prenup
- Everything in the Online Postnup: your agreement, forms for you both to list what you own and owe, your partner's private review page and the signing guide.
UK Prenup is not a law firm and does not give legal advice. If you need a postnuptial agreement now, a family-law solicitor can prepare one.
What Is a Postnuptial Agreement?
A postnuptial agreement is a written agreement two partners make after they marry or form a civil partnership, setting out how their property, savings, pensions, business interests, inheritances and debts would be treated if the relationship ended.
Prenup or postnup?
A postnup is the same agreement as a prenup, made after the wedding instead of before, and a court weighs the two the same way.

Are postnups legally binding?-
Signed After the Wedding
Any time after you marry, so there is no wedding date to rush you. A court still asks whether either of you was pressured.
-
Full Financial Disclosure
The same as a prenup: each of you sets out your own assets, debts and income, so neither signs without knowing what the other has.
-
Independent Legal Advice
The same as a prenup: each of you understands what you are agreeing to, ideally with advice from your own solicitor at a different firm.
-
Judged the Same Way
Not automatically binding, but given effect unless it would be unfair to hold you to it. Postnups were recognised as valid first, in MacLeod v MacLeod (2008).
Postnuptial Agreement Questions
What couples ask about agreements made after the wedding
No. A prenuptial agreement is made before the wedding; once you are married or in a civil partnership, the same kind of agreement is a postnuptial agreement, or postnup. It does the same job, and a court applies the same test to both, as our guide to getting a prenup after marriage explains. Our prenup is only for couples who have not yet married, and our postnup is coming: register your interest and we'll email you when it opens.
Timing. A prenup is signed before the wedding, ideally at least 28 days ahead; a postnup is signed at any time after it. Otherwise they work the same way: both set out how your finances would be treated if the marriage ended, and both depend on full disclosure, independent advice and neither of you being pressured to sign. Our guide compares prenups and postnups side by side.
Not automatically, but postnuptial agreements can carry real weight in England and Wales. Since Radmacher v Granatino (2010) the courts apply the same test to prenups and postnups: an agreement each of you entered freely, understanding what it meant, is given effect unless it would be unfair to hold you to it. A court can always provide for either partner's needs, or any children's, whatever the agreement says.
With a solicitor, a postnup typically costs from around £1,000 to £2,500 plus VAT to draft, with each partner's own advice on top. We haven't set the price of ours yet, and registering your interest is free and commits you to nothing. For comparison, our online prenup is £750 with independent legal advice for one of you, or £1,300 with a solicitor for each of you.
Each of you sets out your finances in full, you agree how your property, savings, pensions, income and debts would be treated, and the agreement is written up. You don't have to use a solicitor, but independent advice is one of the things a court looks at, so each of you should take advice from your own solicitor, at different firms, before you both sign it, each in front of an independent adult witness. Our guide sets out each step of getting a postnup.
Usually when something changes after the wedding: an inheritance or a large gift, starting or buying into a business, a house bought with one partner's money, a career break to care for children, or getting back together after a separation. It is also the route if you meant to make a prenup but the wedding came first, even years into the marriage.
Yes, by making a new agreement after the wedding: a postnup that updates or replaces your prenup. Many prenups, including ours, ask you to review the agreement when a child arrives or your circumstances change substantially. Only a new agreement you both sign changes the terms; until then, the prenup you signed is the one that counts.
