Prenuptial agreements, often called “prenups,” are contracts drawn up by couples before they get married or enter a civil partnership. They outline how assets and finances will be divided if the relationship later breaks down. While prenups have gained popularity in recent years, especially with high-profile cases, there’s still some confusion about their role and enforceability in the UK. Let’s explore what you need to know.
What Exactly Is a Prenuptial Agreement?
At its core, a prenup is a financial plan for the “what if” scenario. It’s a way for a couple to agree on how their money and property will be handled if they divorce or dissolve their partnership. This can include:
- Assets each person brings into the relationship: This is particularly relevant if one person owns a house or business before getting married.
- Assets acquired during the relationship: How will savings, investments, and property bought together be divided?
- Inheritances: A prenup can protect family wealth and ensure it stays within a bloodline.
- Financial responsibilities: It can also clarify who is responsible for debts.
Are Prenups Legally Binding in the UK?
This is where things get a bit nuanced. Unlike some countries, prenups in England and Wales are not automatically legally binding. However, a landmark Supreme Court ruling in 2010 (Radmacher v Granatino) established that courts should give “decisive weight” to a properly executed prenup, provided it’s considered fair.
What Makes a Prenup More Likely to Be Upheld?
To increase the chances of a court respecting a prenup, certain conditions must be met:
- Freely Entered Into: Both parties must sign willingly, without any pressure or coercion.
- Full Financial Disclosure: Each person must be completely open and honest about their assets, debts, and income. No hiding anything!
- Independent Legal Advice: Both parties should have their own separate lawyers to advise them.
- Fairness: The agreement must be considered fair to both parties’ needs, both now and in the future. It can’t leave one person in a vulnerable financial position.
- Timing: It’s best to sign the prenup well in advance of the wedding (at least 28 days is often recommended) to avoid any suggestion of pressure.
Why Are Prenups Becoming More Common?
Several factors contribute to the increasing popularity of prenups in the UK:
- Changing Societal Views: There’s less stigma around prenups now. People see them as a practical way to manage finances, not a sign of distrust.
- Increased Financial Complexity: More couples have significant assets before marriage, such as businesses, inheritances, or substantial savings.
- Second Marriages: People entering second marriages often want to protect assets for children from their first marriage.
- Financial Independence: As women gain greater financial independence, they’re also more likely to consider prenups.

Are Prenups Right for Everyone?
Not necessarily. For some couples, they might seem unnecessary. But they can be a valuable tool for:
- Protecting assets: Ensuring that what’s yours before marriage stays yours.
- Providing clarity: Avoiding lengthy and expensive legal battles if the relationship ends.
- Promoting open communication: Forcing important conversations about finances early on.
The Future of Prenups in the UK
The legal landscape surrounding prenuptial agreements in England and Wales is currently a subject of ongoing debate and potential reform. While the 2010 Supreme Court ruling in Radmacher v Granatino gave prenups significant weight, they are still not automatically legally binding. This means that a court retains the discretion to decide whether to uphold a prenup’s terms, particularly if it’s deemed unfair to one party, especially concerning the needs of children. The Law Commission has recommended that “qualifying nuptial agreements” be introduced, which would be legally binding if they meet specific criteria, such as both parties receiving independent legal advice and making full financial disclosure. However, the implementation of these recommendations is still under consideration by the government, leaving the future of prenup enforceability somewhat uncertain.
For those in Wales considering a prenuptial agreement, it’s crucial to seek expert legal advice. Understanding the current legal framework and ensuring your agreement is drafted to maximise its chances of being upheld is paramount.
