What should be included in a prenuptial agreement and how do you make it legally binding?

A prenuptial agreement in England and Wales is becoming an increasingly popular way for couples to protect assets and gain financial clarity before marriage or civil partnership. Once seen as unromantic, prenuptial agreements are now widely recognised as a practical legal safeguard if a relationship breaks down.

Importantly, while a prenuptial agreement is not automatically legally binding, courts in England and Wales are highly likely to uphold it if it is properly prepared and fair.

So, what should a prenuptial agreement include, and how do you make sure it carries legal weight?

What is a prenuptial agreement?

A prenuptial agreement is a written agreement entered into before marriage or civil partnership. It sets out how assets, income, and finances would be divided if the relationship were to end.

Although prenups are not strictly binding, the courts will usually follow them if they meet certain legal criteria. As a result, careful drafting and legal advice are essential.

What should be included in a prenuptial agreement in England and Wales?

A well-drafted prenuptial agreement in England and Wales should be clear, comprehensive, and tailored to your individual circumstances. It will usually include the following:

Assets owned before marriage

This section identifies assets owned before the relationship, such as:

  • Property owned prior to marriage

  • Savings, investments, and shares

  • Family businesses or inherited wealth

Clearly defining pre-marital assets helps protect them from future claims.

Assets acquired during the marriage

Couples may also agree how assets gained during the marriage will be treated. For example, a prenup can:

  • Ringfence certain assets

  • Set out how jointly acquired property will be divided

  • Protect business growth or future investments

This provides certainty and reduces the risk of disputes later.

Debts and liabilities

A prenuptial agreement should also address financial responsibilities. This includes:

  • Existing debts

  • Responsibility for future borrowing

  • Protection from a partner’s personal liabilities

As a result, both parties have a clear understanding of financial risk.

Income and spousal maintenance

Prenups can deal with spousal maintenance by setting out:

  • Whether maintenance will be paid

  • How long payments would last

  • Whether maintenance is excluded altogether

However, courts will always consider fairness carefully in this area.

Inheritances and family wealth

Many couples use a prenuptial agreement to protect:

  • Future inheritances

  • Family trusts

  • Generational wealth

This is particularly important where family members wish to safeguard assets for future generations.

Review clauses

Importantly, prenuptial agreements should remain fair over time. A review clause allows the agreement to be revisited if circumstances change, such as:

  • The birth of children

  • Significant changes in income

  • A long marriage

Including review clauses helps keep the agreement relevant and enforceable.

What cannot be included in a prenuptial agreement?

Although prenups are flexible, there are limits. A prenuptial agreement cannot:

  • Decide child arrangements or child maintenance

  • Be unfair or leave one party in serious financial hardship

  • Be signed under pressure or without proper understanding

Above all, the welfare of any children will always take priority.

How do you make a prenuptial agreement legally binding?

While no prenuptial agreement is automatically binding, courts in England and Wales are likely to uphold one if the following conditions are met:

  • Both parties receive independent legal advice from separate solicitors

  • There is full and honest financial disclosure

  • The agreement is signed well before the wedding, ideally at least 28 days beforehand

  • The terms are fair at the time of signing and enforcement

  • The agreement is professionally drafted and clearly written

Meeting these criteria significantly increases the agreement’s legal weight.

Is a prenuptial agreement right for you?

Prenuptial agreements are not just for the ultra-wealthy. They can be particularly helpful if:

  • One or both partners own property

  • There is a business or family wealth involved

  • One partner has significantly greater assets

  • There are children from a previous relationship

Therefore, early legal advice is key.
