What is a pre-nuptial or post-nuptial agreement?

A prenuptial agreement is made before marriage or civil partnership, while a postnuptial agreement is made after marriage or civil partnership. Both record how property, savings, inheritance, business interests, pensions and other assets should be treated if the relationship later breaks down. At Lawson West, we’ll advise you on whether an agreement is right for your situation, draft the document and explain the legal safeguards that give it the best chance of being upheld by the court.

Prenuptial vs postnuptial agreements

Agreement type When it is made What it is used for
Prenuptial agreement Before marriage or civil partnership Sets out how assets, property, savings, business interests, inheritance or other financial matters should be treated if the relationship breaks down.
Postnuptial agreement After marriage or civil partnership Records similar arrangements after the couple is already married or in a civil partnership, often following a change in finances, inheritance, business ownership or family circumstances.

Are prenuptial and postnuptial agreements legally binding?

Prenuptial and postnuptial agreements are not automatically legally binding in England and Wales. However, the court will give significant weight to an agreement when both people entered into it freely, understood its implications, gave full financial disclosure, received independent legal advice and the outcome was fair.

The Supreme Court decision in Radmacher v Granatino remains the leading authority. The key principle is that the court should give effect to a nuptial agreement entered into freely by both parties, with full understanding of its implications, unless it would be unfair to do so.

When should you consider a nuptial agreement?

Legal advice on a prenuptial or postnuptial agreement is often worth seeking in the following situations:

  • You own property before the relationship. An agreement records how that property should be treated if the relationship ends.
  • You have children from a previous relationship. An agreement helps protect assets intended for those children.
  • You expect an inheritance or family gifts. It clarifies whether inherited or gifted assets should remain separate from shared finances.
  • You own a business or hold shares. It safeguards business interests and reduces uncertainty if the relationship breaks down.
  • There is a significant difference in wealth between you and your partner. An agreement provides clarity upfront and reduces the potential for future disagreement.
  • Your circumstances have changed since marriage. A postnuptial agreement records new arrangements following an inheritance, business changes, reconciliation, or other major life events.

What can a prenuptial or postnuptial agreement include?

A prenuptial or postnuptial agreement deals with property, savings, pensions, business interests, inheritance, family gifts, debts, maintenance expectations and how certain assets should be treated if the relationship breaks down. It also records arrangements designed to protect children from a previous relationship.

What makes a nuptial agreement stronger?

Several factors strengthen a nuptial agreement and make it more likely to be upheld:

  • Independent legal advice. Each person should understand the effect of the agreement before signing.
  • Full financial disclosure. Both parties should know what assets, income, debts and financial interests exist.
  • No pressure or last-minute signing. A prenuptial agreement should be discussed well before the wedding or civil partnership.
  • Fair terms. The agreement should not leave one person, or any child, in financial hardship.
  • Future changes considered. The agreement should account for children, career changes, inheritance, business growth and other likely changes.
  • Review clause. The agreement should be reviewed after major life events or after a set period.
