What Is a Pre Marriage Contract and Do You Need One?

If you are planning a wedding, you have likely spent time thinking about the guest list, the venue, and the honeymoon. However, one important item that often gets overlooked is a pre marriage contract. A pre marriage contract, also called a prenuptial agreement (or "prenup") is a written agreement between two people that explains how finances and assets would be managed if the marriage ends. It is not about expecting the worst. It is about starting your marriage with clarity and confidence. More couples are choosing to set up a marriage contract before their wedding. Here is what you should know.

What does a pre marriage contract cover?

A pre marriage contract can address many financial topics. The details will depend on your situation, but most agreements include:

• Property. Who owns what, and how any shared property would be divided.
• Savings and investments. How existing and future savings are treated.
• Business interests. Protecting a business you built before the marriage, or one you plan to grow together.
• Inheritances. Ring-fencing family wealth that you want to keep separate.
• Pensions. How retirement funds are handled.
• Debts. Clarifying who is responsible for existing debts brought into the marriage.

A pre marriage contract can also outline broader financial expectations, such as:

• How do you plan to manage money during the marriage?
• What happens if one of you takes time out of work to raise children?
• How would you both be supported if things change?

It does not include arrangements for children. Courts always decide matters involving children based on their welfare at the time, no matter what a prenuptial agreement states.

Is a pre marriage contract legally binding in the UK?

This is a question we hear often. The short answer is that pre marriage contracts are not automatically binding, but courts do take them seriously. In England and Wales, a pre marriage contract is not legally binding in the same way as a commercial contract. However, since the Supreme Court case of Radmacher v Granatino (2010), courts give well-drafted agreements significant weight when deciding how to divide finances during a divorce.

For a pre marriage contract to carry weight, it should meet certain conditions:

• Both parties have independent legal advice. Each person should have their own solicitor review the agreement.
• Full financial disclosure. Both parties need to be open about their assets, income, and debts.
• No pressure or duress. The agreement should be entered into freely, with enough time before the wedding to consider it properly.
• The terms are fair. An agreement that leaves one person in a significantly worse position is less likely to be upheld.

When these conditions are met, the courts will usually respect the agreement unless there is a compelling reason not to.

Who should consider a pre marriage contract?

Pre marriage contracts are not just for wealthy people. They can help anyone who wants to be clear about finances before marriage. You might consider one if:

• You own property or have significant savings. A marriage contract can protect assets you are bringing into the relationship.
• You have a business. If you own or co-own a business, a contract can prevent it from being divided in a divorce.
• You have children from a previous relationship. A marriage contract can help protect assets you want to pass on to your children.
• One of you has substantially more assets than the other. A contract can set fair expectations from the start.
• You are receiving or expecting an inheritance. Ring-fencing family wealth is one of the most common reasons for a pre marriage contract.
• If you or your partner are from different countries, a marriage contract can clarify which country's rules apply. Our team also helps with international prenuptial agreements for couples with cross-border connections.

Even if none of these situations apply, talking openly about finances before marriage can strengthen your relationship. Many clients have told us that these conversations brought them closer.

It is also worth knowing that in England and Wales, there is no such thing as a "common law marriage". If you are living together without being married, you do not automatically have the same financial protections as a married couple.

A pre marriage contract is one way to make sure both of you are protected from the start.

Common concerns about pre marriage contracts

We know that bringing up a marriage contract can feel uncomfortable. Here are some common concerns we hear, along with our responses.

"Won't it seem like I don't trust my partner?"
A pre marriage contract does not mean you do not trust your partner. It is a practical step, like taking out home insurance. You are not expecting the worst, just planning for it. Many couples find that working through the process together actually builds trust by encouraging honest conversations about money.

"We already have a financial adviser. Isn't that enough?"
A financial adviser can help you manage and grow your wealth, but they cannot decide what happens to it if your marriage ends. A pre marriage contract fills that gap. It works with your financial planning to make sure your assets, business interests, and family wealth are protected as you both agreed.

"Isn't it unromantic?"
It depends on how you look at it. Planning your finances together before marriage is a practical way to show you care. You are making sure you both are looked after, no matter what happens.

"Can't we just sort it out later if we need to?"
You can, but it is usually more expensive, stressful, and uncertain. A pre marriage contract gives you a plan you both agreed to when things were calm. Without one, the court makes the decisions.

When should you start the process?

The sooner you start, the better. Ideally, begin talking about a pre marriage contract a few months before your wedding. This gives you both enough time to:

1. Take independent legal advice
2. Gather and share financial information
3. Negotiate and agree on the terms
4. Sign the agreement well ahead of the big day

Starting early also helps avoid any suggestion that someone was pressured to sign. Courts are more likely to uphold an agreement if both people had enough time to think it over. If your wedding is soon, it is still worth having the conversation. If you are already married, a postnuptial agreement (or "postnup") works in a similar way and can be set up at any time during your marriage.
