A prenuptial agreement isn’t meant to cause tension between partners before they marry. Instead, it’s designed to address potential concerns about finances and assets if the couple ever decides to divorce. Discussing these issues before marriage can be easier and less costly than facing disputes and legal fees during a separation.

While getting married is an exciting time, it’s important to consider practical aspects of your future together. One such consideration is whether to sign a prenuptial agreement (prenup). Although not the most romantic topic, prenups offer real benefits—particularly in protecting assets and setting clear expectations in case of divorce. Here, we explore the legal benefits of prenups under UK law and dispel some common myths.

What Is a Prenuptial Agreement?

A prenuptial agreement is a formal, written contract signed by two people before they marry. It outlines how assets and finances will be divided if the marriage ends. Prenups aren’t just for the wealthy—they can benefit any couple wishing to safeguard their assets and avoid future disputes.

Are Prenups Legally Binding in the UK?

Unlike some countries, prenuptial agreements in England and Wales are not automatically legally binding. However, since the landmark 2010 case of Radmacher v Granatino, courts have increasingly respected prenups if certain conditions are met:

  1. Free consent: Both parties must enter the agreement voluntarily, without pressure or coercion.
  2. Full financial disclosure: Both must fully disclose their finances before signing.
  3. Independent legal advice: Each party should have their own solicitor to explain the implications.
  4. Fairness: The agreement should not be grossly unfair or leave one party in serious financial hardship.
  5. Signed well in advance: The prenup should be signed at least 28 days before the wedding.

Even if these are met, courts may modify prenups if circumstances change significantly, such as the birth of children. The agreement usually serves as a basis for financial settlements during divorce proceedings.

Legal Benefits of Prenuptial Agreements

  1. Clarity and Certainty: Couples can clearly agree on how assets—property, savings, businesses—will be divided, reducing conflict and stress if divorce occurs.
  2. Protection of Pre-Marital Assets: Assets acquired before marriage can be safeguarded from division.
  3. Safeguarding Inheritance: Family wealth or inheritances intended for children or relatives can be protected, especially important in second marriages.
  4. Debt Protection: Prevents one partner from being responsible for the other’s debts.
  5. Reducing Legal Costs: Clear agreements can avoid lengthy, costly court battles.

Common Misconceptions About Prenups

  1. “Prenups are only for the rich”: Prenups benefit anyone wanting to protect financial interests, not just the wealthy.
  2. “Signing a prenup means planning for divorce”: It’s about being responsible, like taking insurance—planning for all possibilities without expecting divorce.
  3. “Prenups aren’t fair”: A well-drafted prenup considers both parties’ rights; courts won’t enforce unfair agreements that cause hardship.
  4. “Prenups cover everything”: They can’t decide child custody or support, which courts determine based on the child’s best interests, though inheritance can be mentioned.
  5. “Prenups can’t be changed”: They can be updated if circumstances change, such as after having children or financial shifts.

Final Thoughts

Prenuptial agreements offer couples security, transparency, and peace of mind. Though not the most romantic part of wedding planning, they’re a practical way to manage financial risks. While not automatically binding in the UK, courts increasingly uphold well-prepared prenups.

If you’re considering a prenup, seek independent legal advice to ensure the agreement is fair, correctly drafted, and compliant with UK law. Discussing financial expectations now can save heartache, confusion, and costly disputes later.
