Prenuptial Agreements

A prenuptial agreement (often shortened to prenup) is a written agreement two partners make before they marry in England and Wales. It sets out how your assets, property, savings, pensions, business interests and debts would be divided if the marriage later ended, so you both start married life with clarity and fairness.

A prenup signed before the wedding is the most common type; a postnuptial agreement does the same job but is signed after you marry. Both rely on the same principles: full financial disclosure, fair terms, and ideally independent legal advice for each partner. For a complete explanation, read our guide to what a prenuptial agreement is, or see the three simple steps on our how it works page.

UK Prenup is not a law firm and does not provide legal advice; we recommend each partner takes independent legal advice before signing.

Prenuptial agreements are not automatically binding in England and Wales, but they carry real legal weight. Since the landmark Radmacher v Granatino case, the courts will uphold a prenup that was freely entered into by both partners, with full financial disclosure and a clear understanding of its terms, provided the agreement is fair and meets the needs of both partners and any children.

In practice, a properly prepared prenup signed in good time before the wedding, with independent legal advice on both sides, is very likely to be respected if your circumstances change. To understand exactly how the courts approach them, read our guide on whether prenuptial agreements are legally binding in the UK.

The cost of a prenuptial agreement varies widely. A solicitor drafting one from scratch typically charges several hundred to over a thousand pounds. With UK Prenup you can create your prenup online from just £199, one simple price, with no hidden fees.

Your £199 Prenup + Guide includes a professionally prepared agreement delivered as an instant PDF download, an interactive dashboard, a step-by-step guide and ready-made financial disclosure forms for both partners.

For most couples a prenup is well worth it: a modest one-off cost buys real protection and peace of mind, and helps you avoid expensive, stressful disputes if things ever go wrong. It is especially valuable if you own property, run a business, have children from a previous relationship, expect an inheritance, or simply want a clear, fair financial understanding before you marry.

Prenups aren’t just for the wealthy. To weigh it up for your own situation, read are prenuptial agreements worth it and who should consider a prenup. A prenup is about transparency and peace of mind, not distrust.

A good prenuptial agreement covers everything you each bring to the marriage and how it should be treated: property and your home, savings and investments, pensions, business interests, inheritances and gifts, and any debts. It also sets out how assets and income built up during the marriage are handled.

It all rests on full, honest financial disclosure, both partners listing their finances so you each understand the other’s position before signing. Your prenup includes an interactive dashboard and ready-made disclosure forms that walk you both through exactly what to record.
