What Is a Prenuptial Agreement?
A prenuptial agreement (or "prenup") is a written agreement two partners sign before they marry or enter a civil partnership, setting out how their assets, debts and finances would be divided if the relationship were to end. Also known as a premarital or antenuptial agreement, it's a way for both partners to plan ahead openly and fairly in England and Wales.

Are Prenups Legally Binding in England & Wales?
A prenup isn't automatically binding, but it carries real legal weight. Since the Supreme Court's decision in Radmacher v Granatino (2010), the courts will uphold an agreement that was freely entered into by both partners, with a full appreciation of its implications — unless it would be unfair to hold them to it.
What Can a Prenup Cover?
You can set out how the family home, other property, savings, investments, pensions, business interests and debts would be divided, and ring-fence assets you bring into the marriage — such as an inheritance, a family business, or property and savings you owned beforehand. It's especially useful where one partner has significant premarital or non-matrimonial assets.
What a Prenup Can't Do
A prenup can't override the court's duty to meet both partners' financial needs — the court always has the final say — and it can't decide the arrangements or maintenance for any children, whose welfare comes first. It also can't include lifestyle conditions. To carry real weight, the agreement must be fair to both of you.
Who Is a Prenup For?
Prenups aren't just for the wealthy. They're widely used where one partner owns property or a business, is expecting an inheritance, is marrying for a second time or has children from a previous relationship, or simply wants a clear, shared understanding of finances before the wedding.
How to Make Your Prenuptial Agreement Legally Binding in England & Wales
A prenuptial agreement isn't automatically binding in England and Wales, but the courts give a properly prepared agreement significant weight, following the principles set out in Radmacher v Granatino [2010]. To make your prenup as enforceable as possible and give it the best chance of being upheld in a financial settlement on divorce, both partners should meet the criteria the courts look for and sign in good time before the wedding.
Independent Legal Advice
Each partner should take advice from their own separate solicitor. This shows you both understood the agreement and entered it freely — using the same adviser for both of you can weaken it.
Full & Frank Financial Disclosure
Both partners set out all their assets, debts, income and financial prospects in full. Hiding or understating assets is one of the most common reasons a prenup is later challenged.
Sign at Least 28 Days Before the Wedding
Sign well ahead of the big day — the Law Commission recommends at least 28 days before — so neither partner feels under pressure. Agreements signed at the last minute carry far less weight.
Freely Entered & Fair to Both
The agreement must be entered into freely, without duress or undue pressure, with a full appreciation of what it means, and it must be fair — under the Matrimonial Causes Act 1973 the court can still step in if the terms would leave either partner, or any children, in genuine financial need.
Because you complete everything online, our prenups start from just £199 — a fraction of the £1,500–£5,000 a solicitor-drafted agreement typically costs — and you're free to take your own independent legal advice separately.
How to Sign — and Keep It Safe
When you're both happy, read the agreement through together and each sign it with a clear pen-and-ink signature, ideally after taking your independent legal advice. Your agreement is executed as a deed, so each signature must be witnessed by an independent adult (not each other or a family member) — the execution page of your agreement sets this out and includes the witness blocks. Keep a signed copy each, somewhere safe, and consider giving one to your respective advisers.
Revisit the agreement together if your circumstances change — a new child, a house move or a big change in finances is a good moment to check it still reflects your wishes, or to update it with a postnuptial agreement.
Could Prenups Become Fully Binding?
Back in 2014 the Law Commission proposed "qualifying nuptial agreements" that would be binding by law where key safeguards are met. The government revisited the idea in its 2024 scoping report and is expected to consult on wider reform, but for now prenups are not binding by statute — so meeting the criteria above is what matters most.
Common Questions About Prenuptial Agreements
Quick answers to the questions we hear most. For the full list, visit our FAQ page.
Creating a prenuptial agreement before marriage in England and Wales is straightforward. Both partners complete the details online, set out their assets, debts and income, and we generate your agreement. You then review it together, ideally take independent legal advice, and both partners sign it well before the wedding.
Prenuptial agreements are increasingly given weight by the courts in England and Wales, particularly where both partners entered into the agreement freely, with full financial disclosure and their own independent legal advice. UK Prenup is not a law firm and does not provide legal advice — both parties should consider independent legal advice before signing.
Our prenup service is £199 to create your agreement online, plus a personal prenup dashboard with step-by-step prompts and ready-made disclosure checklists for both partners. There are no hidden fees or subscriptions — £199 is the all-in price for both partners.
Most couples complete the online details in one sitting — around 15–30 minutes with your financial details to hand — and your agreement is generated straight away. We recommend leaving plenty of time before the wedding so both partners can review it carefully and take independent legal advice — agreements signed well in advance, never at the last minute, carry the most weight.
You can create your prenup with us online, but we strongly recommend that each partner takes their own independent legal advice before signing — this helps confirm that both of you understood and freely agreed to the terms. UK Prenup is not a law firm and does not provide legal advice.
Technically, yes — a couple could write their own agreement from scratch. However, DIY agreements often miss important details, use unclear wording, or skip full financial disclosure, which can undermine the whole agreement. Our professionally structured prenups start from just £199 and prompt both partners to set out their finances clearly. We recommend each partner also takes independent legal advice before signing.
Both partners should set out their full financial picture so the agreement is built on complete, honest information. That means listing your property and assets (the family home, other property, vehicles, valuables, inheritances and gifts), savings and investments (bank and savings accounts, ISAs, pensions, shares and business interests), debts and liabilities (mortgages, loans, credit cards, overdrafts, car finance and student loans), and your income and future plans (salary, rental income and any expected inheritances). When you create your prenup, your personal dashboard walks both partners through a full disclosure checklist so nothing important is missed.
Prenuptial agreements aren't automatically binding in England and Wales, but the courts will usually uphold one that meets the criteria set out in Radmacher v Granatino. To give your prenup the best chance of being upheld, both partners should take their own independent legal advice from separate solicitors, exchange full and frank financial disclosure, sign the agreement at least 28 days before the wedding, and make sure the terms are fair and don't leave either partner or any children in financial need.
