Entering into a marriage is an exciting milestone, but it is also a significant legal and financial commitment. While it may not feel romantic to discuss the "what ifs," a prenuptial agreement (often called a "prenup") is a practical tool that can provide both partners with peace of mind and clarity for the future.

This guide explains what a prenuptial agreement is, why you might consider one, and how the process works in England and Wales.

What Is a Prenuptial Agreement?

A prenuptial agreement is a formal, written contract entered into by a couple before they get married. It outlines how their assets, such as property, savings, debts, and pensions, should be divided if the marriage were to end in divorce or dissolution.

By establishing these terms early on, a prenup allows couples to protect their individual interests and enter into marriage with a transparent understanding of their financial relationship.

Are Prenuptial Agreements Legally Binding?

In England and Wales, prenuptial agreements are not currently automatically legally binding in the same way as a standard commercial contract and a court can disregard them on grounds of fairness.

Following key court rulings, however, they are now given significant weight by the courts on divorce or dissolution.

Provided the agreement is entered into freely, both parties understand the implications, and the terms are fair, a court is likely to uphold the agreement with the onus being on the party seeking to overturn the agreement to prove that it is not fair.

To ensure your prenup has the best chance to be upheld by a court, it must meet specific criteria:

  • It must be signed at least 28 days before the wedding.

  • Both parties must provide full financial disclosure of their assets.

  • Both parties must have received independent legal advice.

  • The agreement must be "fair" and meet the needs of both parties and any children.

Why Should I Consider a Prenup?

Prenuptial agreements are no longer just for the wealthy. They are increasingly common for couples from all walks of life who want to protect their autonomy. You might consider a prenup if:

You have inherited assets: You wish to keep family inheritance or gifts separate from matrimonial property.

You own a business: You want to ensure your business remains under your control and is not disrupted by a potential divorce.

You have children from a previous relationship: You want to ringfence certain assets to ensure they are passed on to your children.

You already own property: You are entering the marriage with significantly more assets than your partner and want to protect your pre-marital wealth.

How Does the Process Work?

Creating a prenuptial agreement follows a structured process to ensure it is robust and fair:

1. Open Discussion. You and your partner discuss your financial goals and what you would like the agreement to cover as soon as possible, prior to the wedding.

2. Financial Disclosure. Both parties provide a full list of their assets, debts, and income. Transparency is essential for the agreement to be valid.

3. Drafting the Agreement. A solicitor drafts the document based on your specific requirements.

4. Independent Legal Advice. Each person must have their own solicitor review the document to ensure they understand the terms and are not being pressured.

5. Timing. The document is agreed, signed and witnessed at least 28 days before the wedding date.

What Happens if We Don’t Have a Prenup?

Without a prenuptial agreement, the court has wide discretion to divide assets according to "fairness" under the Matrimonial Causes Act 1973. This often starts with a 50/50 split of all assets, regardless of who brought them into the marriage. This process can be lengthy, expensive, and emotionally draining if the couple cannot agree.

Do I Need Legal Advice?

Because a prenuptial agreement involves waiving certain legal rights, it is vital to seek professional legal advice. A solicitor ensures that the document is drafted correctly and complies with current case law, making it much more likely to be upheld by a judge in the future.

If you are already married and didn't sign an agreement, you can still enter into a Postnuptial Agreement, which works in a very similar way.
