How to Get a Prenup in the UK: 2024 Step-by-Step Guide
Are you looking to protect your business, assets, or children’s future before marriage? You’re in good company. With a rising number of UK couples choosing prenuptial agreements, more founders and professionals are seeking clarity and legal security. But drafting a prenup carelessly—without proper process or advice—can expose you to costly court battles.
Below, you’ll discover a clear, practical route to securing a robust prenuptial agreement in England and Wales. These steps help you avoid the most common pitfalls while maximising your agreement’s enforceability:
- Begin the Conversation Early
Discuss your intentions openly with your partner well before wedding plans are final. Rushing the process or springing it on your partner last minute can undermine the agreement’s validity. - List and Value All Assets and Debts
Both parties must make a written, detailed disclosure of all property, investments, pensions, valuable possessions, business interests, and debts. This is a core legal requirement. - Agree Your Shared Objectives
Be clear about what each of you want from the agreement—whether it’s protecting a specific business, ringfencing family inheritances, or clarifying the division of debts. - Draft the Prenup Using a Lawyer-Drafted Template
Use a template built to UK legal standards. Tailor each section to your unique circumstances—don’t rely on imported or generic documents. Our platform’s templates have been thoroughly reviewed for 2024 compliance. - Independent Legal Advice for Each Party
Each of you must receive advice from separate legal professionals. This is not just best practice—it’s a key step that UK courts look for if the agreement is ever scrutinised. - Negotiate and Finalise Terms
Take time to address any disagreements or ambiguous points. Both parties should feel confident and unpressured before signing. - Sign in the Presence of Witnesses and Store Securely
Both must sign the final, printed version with independent witnesses present. Keep copies in a secure digital folder or with your legal experts. - Sign at Least 28 Days Before the Wedding and Plan for Future Reviews
Aim to complete signing at least 28 days before marriage. Schedule future reviews after life events like children or significant asset changes.
A couple, Priya and Dan, used our prenup checklist to work through each required disclosure and clause, gathering all essential documents. This helped them agree fair terms and secure their business interests—without last-minute stress.
Avoid agreements that are verbal, unsigned, or completed when either partner feels rushed—courts are far more likely to disregard such documents.

What Is a Prenuptial Agreement in the UK and Why Have One?
A prenuptial agreement (“prenup”) is a private contract made before marriage that sets out how assets, property, pensions, and debts will be shared if the relationship ends. While not automatically binding under English law, courts treat thoroughly drafted prenups with growing respect—especially since Radmacher v Granatino [2010].
Common reasons couples get a prenup:
- Safeguarding a business or professional practice.
- Ringfencing family wealth or inheritances.
- Avoiding uncertainty about future financial rights.
- Protecting children’s interests—especially from previous relationships.
A London-based business founder, Saira, used a tailored prenup to keep her tech company separate from future divorce claims. Her agreement specified that all shares and intellectual property relating to the business would stay with her.
Prenups aren’t just for multimillionaires. Anyone with personal savings, property, or children from a previous partnership can benefit from the clarity and protection a prenup offers.
Who Should Consider a Prenup in England & Wales?
Not all couples need a prenup. However, you should seriously consider one if:
- You have pre-marital assets (property, shares, savings) you wish to keep separate.
- There are children from a prior relationship, and you want to protect their inheritance.
- You or your partner are business owners or anticipate significant inheritance.
- You wish to limit responsibility for each other’s debts.
Stuart and Maya were both entrepreneurs, each running their own successful businesses. A prenup let them agree in advance that both companies would remain separate and unaffected, whatever happened to their marriage.
Prenups are particularly valuable for business owners. A well-drafted agreement safeguards not only your interests but also those of co-owners and employees if your personal circumstances change.
Essential Information and Documents for a UK Prenup
Sound prenuptial agreements require honest, accurate disclosure and evidence. You should prepare:
- Recent statements for all bank accounts and savings.
- Current valuations for property, vehicles, or businesses.
- Documents for pensions and potential inheritances.
- Full details of debts—credit cards, loans, liabilities.
- Written proof of income, like payslips or self-employed accounts.
Olivia meticulously gathered statements from her ISAs, a property valuation report, and her latest pension summary. This transparency made negotiation faster and helped avoid later disputes.
Omitting financial information can render your entire prenup worthless. Courts can—and do—set aside agreements if full and frank disclosure is missing.
Key Clauses to Include in a UK Prenuptial Agreement
A valid prenup isn’t just about dividing assets—it’s about covering every risk. Include these vital clauses for maximum legal strength:
| Clause/Component | What It Means | Why It’s Important |
|---|---|---|
| Full Financial Disclosure | Both parties reveal all assets, debts, and income. | Ensures fairness and prevents challenges. |
| Independent Legal Advice | Each party gets legal advice from separate professionals. | Strengthens enforceability in court. |
| Voluntary Agreement | Both parties confirm they signed freely, not under duress. | Avoids claims of coercion. |
| Business Asset Protection | Specifies treatment of business interests. | Secures business continuity. |
| Property Division | Sets out property split rules. | Clarifies big-ticket asset outcomes. |
| Debt Responsibility | Details who pays which debts. | Prevents unfair burdens. |
| Review Clause | States when the agreement should be reviewed. | Keeps terms relevant over time. |
An events company owner, Jamie, made sure his prenup required annual reviews whenever his business secured a new funding round—so that the agreement always matched his growing asset base.

Are Prenups Enforceable in UK Courts? Your Legal Checklist
A prenuptial agreement can shape how courts decide financial matters, provided key tests are met:
- Both parties must enter the agreement freely, fully understanding the consequences.
- A complete financial disclosure for both parties is necessary.
- Each party receives independent legal advice before signing.
- The agreement does not attempt to exclude the court’s ability to make fair orders or disadvantage children.
UK courts do not automatically follow prenups, but a clearly written, fairly negotiated agreement is likely to be respected following Radmacher v Granatino [2010].
Katie and Simon followed every stage—early discussions, mutual legal advice, and full disclosure. When their relationship ended, the court gave heavy weight to their agreement and divided finances as they had requested.
Even a perfect prenup must put the children’s welfare first. No agreement can override a child’s legal rights or needs in the eyes of a UK court.
What Can and Can’t Be Included in a UK Prenup?
A UK prenuptial agreement deals with financial, property, and business-related issues only. It cannot overrule parental responsibility or fairness under the law.
Permitted in a prenup:
- Future ownership of family homes and investment properties.
- Savings, shares, ISAs, pensions, and business assets.
- Rules for splitting debts or joint liabilities.
- Responsibility for legal costs in event of a dispute.
Not permitted:
- Child custody or maintenance arrangements.
- Any attempt to limit court powers or require illegal conduct.
- Personal or lifestyle clauses (e.g., infidelity clauses) that have no legal force.
Steve wanted to add a clause stating his wife would lose all rights to the family home if she filed for divorce. Both their legal advisers warned that such a punitive clause would likely be disregarded by the court.
Stick to clear, financial terms and avoid emotional or punitive conditions that won’t survive legal scrutiny.
Prenup vs. Postnup: Which One Do You Need?
A prenuptial agreement is completed and signed before marriage; a postnuptial agreement (postnup) is the same in content but signed after the legal wedding. Both can protect your assets, provide clarity, and influence a court’s decision in case of divorce.
- Prenups are often stronger, as the legal relationship has not yet begun.
- Postnups can remedy oversights if you missed out on a prenup or your circumstances change—like receiving an unexpected inheritance or starting a new business.
Anna and Shahid married quickly without time for a prenup. A year later, Anna’s parents gifted her a house, so they used a postnup to clearly earmark the property as Anna’s sole asset.
Missed the wedding deadline? Don’t panic—a properly drafted postnup signed after the event can still offer robust protection under English law.
Mistakes That Make a Prenup Unenforceable in the UK
Many UK prenups fail because of basic oversights or misunderstandings. Watch out for these critical errors:
- Hiding, undervaluing, or failing to disclose assets or debts.
- Failure by both to get truly independent legal advice (never share the same adviser).
- Signing just before the wedding, or under emotional pressure.
- Terms that are so unfair one party would face hardship, or that ignore children’s needs.
- Not keeping the agreement up to date after children, property purchases, or income changes.
Ellen and Martin, under time pressure, both used the same solicitor and quickly signed the prenup three days before their wedding. The court later disregarded the document for lack of fairness and proper process.
Schedule reviews every two to three years or after significant life changes to keep your prenup relevant and enforceable.

Frequently Asked Questions
Is a prenuptial agreement legally binding in the UK?
No, prenups are not automatically binding. However, agreements that are freely entered, follow full disclosure, and have independent legal advice are now likely to be respected by the courts if fair and reasonable.
How much does a prenuptial agreement cost in the UK?
Traditional solicitor advice and drafting can cost £1,000 to £5,000 or more. Our AI templates and smart review tools help you create a valid prenup at a fraction of the cost, without sacrificing legal rigour.
When should a prenup be signed before marriage?
At least 28 days before the wedding—ideally even earlier. Signing late or under time pressure increases the risk your agreement will be set aside.
Can a prenup be changed after marriage?
Yes. Changes require a “postnuptial agreement”, meeting the same legal standards for disclosure and fairness, with new independent legal advice.
Do both partners need a solicitor for a prenup agreement?
Each party must take their own legal advice. This is vital—courts may ignore agreements if only one solicitor was involved or if one partner did not properly understand the terms.
What happens if you don’t have a prenup in the UK?
Courts use their discretion to divide all marital assets under the laws of fairness, usually resulting in an equal split if no agreement exists.
Can you protect future business assets with a prenup?
Yes. Prenups can address both current and future business interests, including specifying how any future growth or new ventures will be treated on divorce.
Does a prenup cover child custody or child maintenance?
No, child arrangements are excluded. UK courts retain the power to decide what’s best for any children, regardless of what’s in your prenup.
How do courts decide if a prenup is fair?
Courts assess disclosure, advice, freedom of consent, and overall fairness. Agreements that are one-sided, unfair, or outdated risk being ignored.
Are prenups suitable for second marriages?
Yes. Prenups are a common tool for people entering second marriages, helping to protect assets and ensure that children from previous relationships inherit as planned.
