About Us

Zeus Family Law Cardiff and South Wales and South West - Post-nuptial and pre-nuptial agreements

Future-Focused Planning with Clarity and Care

We believe that planning for the future shouldn’t feel uncomfortable or confrontational. Nuptial agreements are increasingly common and offer both parties a chance to define what is fair from the outset, based on mutual respect and open communication.
Our specialist family solicitors advise clients across South Wales on both pre- and post-nuptial agreements, providing honest advice and robust legal drafting that ensures each agreement stands up to scrutiny if ever needed.

What Is a Nuptial Agreement?

A nuptial agreement is a legal document that sets out how finances, assets, and property should be dealt with if a marriage ends. These agreements can also reflect wider intentions, such as spousal maintenance or keeping family businesses, inheritances or specific assets separate.

Pre-nuptial agreements are created before marriage. They’re often used when one person has significantly more assets, is entering a second marriage, or wants to protect wealth for children from a previous relationship.

Post-nuptial agreements, by contrast, are made after marriage. They may follow a financial change — such as inheritance or business growth — or simply help to formalise arrangements during a reconciliation or family restructure.

In both cases, the goal is the same: to agree matters clearly, fairly and in advance, helping to avoid unnecessary uncertainty in the future.

Common Scenarios We Advise On

Entering a second marriage and wanting to protect assets or children’s inheritance

Receiving a significant gift or inheritance and wanting to keep it separate

Running a business and seeking to protect its value in case of separation

Making formal arrangements after reconciliation or changes in financial circumstances

Are Pre- and Post-Nuptial Agreements Legally Binding?

In England and Wales, pre- and post-nuptial agreements are not automatically legally binding. However, courts increasingly uphold them, provided certain conditions are met.

The leading case of Radmacher v Granatino [2010] UKSC 42 confirmed that the court will generally give effect to a nuptial agreement unless it would be unfair to do so.

To carry legal weight, a nuptial agreement should be:-

Freely entered into by both parties, without pressure or coercion;

Supported by full financial disclosure from both sides;

Based on independent legal advice for each person;

Signed well in advance of the wedding (for pre-nups);

Fair and reflective of the couple’s circumstances at the time of enforcement.

While the court retains final discretion, a properly drafted agreement can be highly persuasive and help avoid uncertainty during divorce proceedings.

“Sophie was recommended to me. She was amazing! Very knowledgeable and straight talking – exactly what I needed. After being advised by Sophie, I felt a lot more optimistic about my ongoing case. She gave me confidence, this was something that I didn’t receive from my previous solicitor.”

Frequently Asked Questions

Are pre-nuptial and post-nuptial agreements legally binding in England and Wales?

Whilst these agreements are not automatically legal binding, courts are likely to uphold them, provided that they are properly drafted and fair.

What is the difference between a pre-nuptial agreement and a post-nuptial agreement?

Whilst both serve the same purpose, the key difference between these agreements is timing. A pre-nuptial agreement is made before marriage, and a post-nuptial agreement afterwards.

Do both partners need a solicitor?

Yes, each partner should obtain independent legal advice when considering a pre-nuptial or post-nuptial agreement, especially if you want to ensure that the agreement will be upheld in court.

Can we include child arrangements in a pre-nuptial or post-nuptial agreements?

You can discuss intentions; however, child arrangements will ultimately be decided in the best interests of the child at the time, either of separation or later, if parents cannot agree on these.

How much will a pre-nuptial or post-nuptial agreement cost?

At Zeus Family Law, we offer a complimentary 20-minute consultation so you can understand your rights and whether a pre- or post-nuptial agreement is the right step for you. If you decide to proceed, our experienced solicitors will provide a clear, tailored estimate based on your individual circumstances, so there are no hidden costs or surprises.

Can I use a pre-nuptial or post-nuptial agreement to protect my business or inheritance?

Yes, these agreements can effectively ring-fence business interests or family wealth, and ensure that these are preserved in the event of separation.

What if our circumstances change after we sign the nuptial agreement?

We recommend reviewing a nuptial agreement if major life events occur, such as children, inheritance, or changes in income.

What if my partner refuses to sign a nuptial agreement?

You cannot force your partner to sign a nuptial agreement; however, we can help you approach this conversation in a constructive way and explore alternative ways to protect your position.
