What is a Prenuptial Agreement?

A prenuptial agreement—commonly known as a prenup—is a written contract made between two people before they marry or enter into a civil partnership.

This agreement allows them to set out how they wish to manage their financial affairs during the marriage and, crucially, what will happen to their finances, property, and other assets if the marriage ends in divorce or death.

It’s essentially a safeguard, helping couples clarify their financial arrangements from the outset and avoid future disputes.

Marriage automatically grants each partner certain rights under UK law. For example, without a prenuptial agreement:

  • Property, savings, and retirement funds acquired during the marriage could be divided between the spouses upon divorce.
  • One spouse may be required to pay spousal maintenance if the other is financially disadvantaged after the marriage ends.
  • Each spouse could have a claim on the other’s estate after death.

A prenuptial agreement allows couples to override some of these automatic legal entitlements, giving them more control over how their assets are divided and ensuring their wishes are clear.

For example, if one partner owns a property before the marriage, they may wish to keep it separate and not have it divided if they divorce.

The prenup provides certainty by laying out these specific intentions in writing, helping to avoid expensive and emotionally draining court battles later on.

Key Elements of a Prenuptial Agreement

  1. Division of Property: Couples can agree in advance how their property will be split if they divorce. This includes:
    • Pre-marital property: Assets one partner owned before the marriage, like a house or savings.
    • Marital property: Assets acquired during the marriage, such as a jointly owned home, cars, or savings.
    • Future earnings: You can also decide whether any income or property earned after the marriage will be shared or kept separate.
  2. Spousal Support: The couple can use a prenup to determine whether one spouse will receive financial support from the other if they divorce, and how much. In the UK, there’s no automatic right to spousal support, but without a prenup, the courts can order one spouse to provide ongoing financial support to the other if it’s deemed fair.
  3. Retirement and Pensions: Couples can also specify how their pension plans and retirement savings will be handled upon divorce. Without a prenup, pensions accumulated during the marriage could be divided between both parties, which may not be what either partner wants.
  4. Debt Responsibilities: Prenups can clarify who will be responsible for any debts incurred during the marriage. For example, if one spouse enters the marriage with significant debts, the agreement can ensure the other partner won’t be liable for them in the future.
  5. Inheritance and Family Assets: If you or your partner expect to receive an inheritance during the marriage or already hold family assets, a prenuptial agreement can ensure those assets remain within the family and aren’t shared in the event of a divorce.

Postnuptial Agreements and Separation Agreements

While a prenuptial agreement is made before marriage, a postnuptial agreement is similar but is entered into after the marriage has taken place.

Postnuptial agreements can be useful if:

  • The couple didn’t arrange a prenup but decide later on they want to set out financial arrangements.
  • The couple’s financial situation changes significantly during the marriage, such as one partner receiving a large inheritance or starting a new business.

If divorce is imminent, couples often draw up what’s called a separation agreement, which is a form of postnuptial agreement that sets out how they will divide their assets, manage debts, and arrange spousal support while they’re still married but living separately. This can help ease the legal process when they move to formalise the divorce.

Is a Prenuptial Agreement Legally Binding in the UK?

In short, prenuptial agreements (prenups) are not automatically legally binding in the UK, but they are increasingly being taken seriously by the courts, especially since a major legal case in 2010.

Let me explain what this means in simple terms.

When something is legally binding, it means the courts must follow what is written in the agreement. In the UK, prenuptial agreements don’t have automatic legal binding status.

Instead, they are viewed as a factor the court considers when deciding on financial arrangements during a divorce.

However, if the prenuptial agreement meets certain important conditions, the court is more likely to respect the terms of the prenup.

In other words, while a prenup isn’t guaranteed to be followed by the court, it can carry significant weight if it’s done properly.

In 2010, there was a famous case called Radmacher v Granatino, where the UK Supreme Court ruled that a prenuptial agreement should be upheld. This was a big turning point because, before this case, courts were less likely to enforce prenups.

In this case, the court clarified that prenuptial agreements could be enforced, but only if they meet certain fairness criteria and both parties clearly understood their agreement.

What Conditions Must Be Met for a Prenup to Be Enforceable?

For a prenuptial agreement to be upheld in court, it should satisfy the following conditions:

  1. It must be freely entered into: This means both parties need to have signed the agreement without being pressured or forced into it. If one partner was pushed into signing it, the court might not accept the prenup.
  2. Both parties must fully understand the agreement: Both people must know exactly what they are agreeing to. Each person should get independent legal advice from their own solicitor, so they are fully aware of their rights and what the prenup means for them.
  3. Full disclosure of financial assets: Both parties must be completely open about their financial situation. This includes disclosing all properties, savings, debts, and other assets. If someone hides information or doesn’t provide full financial disclosure, the agreement may not be valid.
  4. The agreement must be fair: The court will also consider whether the terms of the prenuptial agreement are fair to both parties. If the agreement is heavily biased in favour of one partner and leaves the other in a much worse position, the court may not follow it.
  5. It must not prejudice the interests of children: If the couple has children, the prenup must not negatively affect them. The court’s priority is always the well-being of any children involved. If the prenup ignores the financial needs of children or doesn’t provide for them adequately, the court may not enforce it.

What Role Does the Court Play?

Even if your prenup meets all of the above conditions, the court still has the final say.

Prenups are considered “persuasive” but not binding.

This means that the court will consider the prenuptial agreement and give it weight, but it has the power to decide whether it is fair in the circumstances at the time of divorce.

Courts have a lot of flexibility under the Matrimonial Causes Act 1973, which means they can adjust the terms of a financial settlement if they feel the prenup is unfair or inappropriate given the couple’s current situation.

Step-by-step guide on how to get a prenup

Initial Consultation

The process begins with an initial consultation between each party and their respective solicitors. This aims to discuss individual concerns and expectations for the prenuptial agreement. It is important that both parties have independent legal advice.

Disclosure of Assets

Both parties must provide a full and frank disclosure of their assets, liabilities, and financial status. This ensures transparency and builds a foundation for a fair agreement.

Step

Details

Consultation

Each party meets with their solicitor

Disclosure

Full financial disclosure from both parties

Negotiation

After disclosure, the negotiation phase starts. Each party’s solicitor will negotiate on behalf of their client to agree on the terms. This should include division of property, treatment of savings and investments, and any debts.

Key Elements to Consider:

  • Property ownership
  • Division of savings and investments
  • Debt responsibilities

Drafting the Agreement

Once negotiations are complete, the solicitors draft the agreement. This document outlines the terms and conditions agreed upon. Both parties review the draft to ensure it accurately reflects their intentions.

Signing

The final step is signing the agreement. It must be signed by both parties in the presence of a witness. This should occur well before the wedding date to avoid any claims of undue pressure.

Timeline:

  • Initial Consultation: 1-2 weeks
  • Disclosure & Negotiation: 4-6 weeks
  • Drafting & Signing: 2-3 weeks

Why Consider a Prenuptial Agreement?

A prenuptial agreement offers clarity, security, and peace of mind by clearly documenting how financial matters will be handled during the marriage and in the event of a divorce.

Here are several scenarios where a prenup could be particularly important, and examples of how it might apply to everyday situations:

1. Couples with Significant Assets

If you or your partner are entering the marriage with a substantial amount of wealth—whether it’s through savings, investments, or property—you may want to ensure these assets are protected in the event of a divorce.

Example:
Imagine that Sarah owns multiple properties she inherited from her grandparents. When she gets married to Tom, she wants to make sure that these properties stay within her family and don’t get divided up if they ever divorce. A prenuptial agreement can specify that these properties will remain Sarah’s separate assets, ensuring her family’s legacy is protected.

2. Those Entering a Second Marriage

For individuals who have been married before, especially those with children from a previous relationship, a prenup can be a way to protect both their own assets and the financial future of their children.

Example:
James is remarrying after being divorced for five years. He has two children from his previous marriage and wants to make sure that a portion of his savings and investments will go to them, regardless of what happens in his new marriage. A prenup can outline specific provisions to ensure that his children’s inheritance is safeguarded.

3. Business Owners Protecting Their Business Assets

If you own a business, a prenuptial agreement can help prevent your business from being split up or sold off in the event of a divorce. This is crucial for maintaining control over your business’s future and ensuring it doesn’t become entangled in personal disputes.

Example:
Jessica owns a successful catering company. When she marries Ryan, they agree to a prenuptial agreement that specifies Jessica will retain full ownership of the business if they divorce. This protects the business, her employees, and its long-term prospects, ensuring it doesn’t need to be sold or divided.

4. Individuals with Family Inheritances

Family inheritances can often be a sensitive topic, especially when they involve family properties or heirlooms. A prenup can help protect those assets and ensure they stay within the family, even if the marriage ends.

Example:
Daniel’s parents recently passed away, leaving him a significant inheritance. Although he fully trusts his partner, he wants to ensure that this money remains separate and is passed on to his children in the future. A prenuptial agreement can outline that the inheritance remains Daniel’s separate property and won’t be divided in a divorce.

5. Couples with Children from Previous Relationships

A prenuptial agreement can be crucial for couples who have children from previous relationships. It can ensure that specific assets or provisions are set aside for those children, especially if the new marriage introduces more complexity into the family dynamic.

Example:
Emma and Mark are getting married, but both have children from previous relationships. They want to make sure that each child is financially secure and has a clear understanding of what they will inherit. By signing a prenup, they can ensure that certain assets—such as their family homes or savings—are preserved for their respective children, regardless of what happens to the new marriage.

6. Protecting Future Earnings or Career Investments

In some cases, one spouse may have significantly higher earning potential due to a specific career path or education. A prenup can protect the future income of a partner who has invested heavily in their career or studies.

Example:
Sophie is a doctor in training and expects to earn significantly more once she completes her specialisation. She and her fiancé, Adam, agree to a prenup that recognises Sophie’s future career earnings as separate, in case of divorce. This agreement protects the investments Sophie has made in her career and the potential financial rewards she will reap from it.


What Happens Without a Prenuptial Agreement?

Without a prenup, if you and your spouse divorce, the court has the power to divide assets and finances based on what it considers to be fair under Section 25 of the Matrimonial Causes Act 1973. The court considers factors such as:

  • Each party’s income and financial needs.
  • The standard of living enjoyed during the marriage.
  • The contributions (financial and non-financial) of both parties.

However, the court’s idea of fairness may not align with the personal preferences or agreements the couple had during their marriage.

For example, you may have intended to keep certain assets separate, but without a prenup, the court could decide to include those assets in a financial settlement.

A prenuptial agreement allows couples to make these decisions themselves, without leaving them up to the court’s interpretation.

Legal Cases That Highlight Prenup Law

The case of Radmacher v Granatino is a landmark example in UK prenuptial law. The Supreme Court recognised the enforceability of prenuptial agreements more clearly, provided they were freely entered into with full appreciation of their implications.

In this case, the court held that the prenuptial agreement should be given decisive weight, as both parties understood its significance and there was no evidence of duress or lack of mental capacity.

Another relevant case is Kremen v Agrest, which emphasised the importance of full financial disclosure.

The court ruled in favour of the applicant, who successfully challenged the agreement on the grounds that significant assets were hidden during the signing process.

The 2010 Supreme Court test case of Radmacher v Granatino, overturned the previous legal framework on them to recognise changing societal and judicial views on the personal autonomy of married partners.

Pre-nuptial agreements can now be enforced by the courts as part of their discretion in financial settlement cases under section 25 of the Matrimonial Causes Act 1973 so long as the three-stage Radmacher test is met and it is considered fair to do so, keeping in mind the interests of any child of the family.

Radmacher holds that the courts will give effect to a nuptial agreement that is freely entered into by each party with a full appreciation of its implications unless in the circumstances prevailing, it would not be fair to hold the parties to their agreement.

The case provided substantial amounts of guidance relevant to all nuptial agreement cases that have occurred since 2010.

What are the grounds for challenge?

A prenuptial agreement can be challenged if it was signed under duress. This means one party was forced or coerced into agreeing to the terms.

For example, threats or undue pressure leading up to the signing could render the agreement void.

This underscores the importance of discussing your prenup in advance of getting married. A prenup should not be a last minute decision and cannot be signed right before tying the knot.

Mental incapacity is another ground for challenge. If either party was not in a sound mental state when the agreement was signed, the agreement may be invalid. Evidence of mental illness or impairment at the time of signing can be crucial in such cases.

Incomplete disclosure of assets is also a significant factor. Both parties must fully disclose their financial positions. Hidden assets or fraudulent misrepresentation can lead to a successful challenge. Transparency is critical to uphold the validity of a prenuptial agreement.

Ultimately, while a prenuptial agreement can offer many advantages, it is essential for couples to communicate openly and seek professional advice to ensure the agreement is fair and comprehensive.
