Overview

Creating greater clarity and certainty for the future

What are postnuptial agreements?

A postnuptial agreement can protect your finances, property, and family interests if your relationship breaks down. More couples are choosing postnuptial agreements as part of sensible long-term financial planning, especially when children, businesses, or inherited wealth are involved.

Postnuptial agreements are created after marriage or a civil partnership and clearly set out how assets and financial support will be divided if the relationship ends. Having a clear, properly drafted agreement can reduce uncertainty, prevent conflict, and give both parties peace of mind. Courts will uphold postnuptial agreements that are fair and legally sound.

What does a postnuptial agreement cover?

  • property
  • savings
  • debt
  • income
  • business ownership
  • inheritance
  • maintenance
  • pensions.

Are postnuptial agreements legally enforceable?

Postnuptial agreements are not automatically binding, but courts will often uphold them where they are properly prepared and considered fair. The agreement must meet both parties’ needs and properly consider the welfare of any children. It should also:

  • be created voluntarily by both parties
  • have full financial disclosure
  • be drawn up with independent legal advice.

Why do couples choose to make a postnuptial agreement?

There are a number of reasons to create a postnuptial agreement, but often if the assets within a marriage or partnership are complex, then it can give clarity about what each partner should be entitled to and how to make a fair division in the event of family breakdown. These circumstances include:

  • When there has been a change in income or an inheritance that has an impact on the family’s financial position.
  • To help protect assets such as a family business, inheritance or property acquired before the relationship. To ensure children from a previous relationship are protected financially.
  • If you have already separated from your partner and are considering divorce.

Nuptial agreements are becoming an increasingly practical way for couples to plan for the future. Whether entered into before or after marriage, these agreements can help protect pre-marital assets, family wealth, and business interests while providing clarity about how finances would be handled if the relationship ended. In this article, we explain how prenuptial and postnuptial agreements work in England and Wales, when courts are likely to uphold them, and why more couples are choosing to put one in place before saying “I do.”

Postnuptial agreement FAQs

A postnuptial agreement (often called a “postnup”) is a legal document entered into after a couple is married or in a civil partnership. It sets out how assets, property, income and pensions would be divided if the relationship were to end in divorce or dissolution.

At Tees, we work closely with you to ensure the agreement reflects your shared intentions and protects what matters most to you.

Postnuptial agreements are not automatically legally binding in England and Wales. However, the court will generally uphold a postnup if it has been properly prepared, is fair, and both parties entered into it freely with full financial disclosure and independent legal advice.

Our family law specialists ensure your postnuptial agreement is robust and drafted in line with the latest guidance from the courts, giving it the strongest possible standing.

Couples choose postnuptial agreements for many reasons, including:

  • Protecting inherited or family wealth

  • Safeguarding business interests

  • Clarifying financial arrangements after marriage

  • Providing certainty following reconciliation

  • Ring-fencing assets acquired before the marriage

A postnup can provide clarity and peace of mind, particularly where financial circumstances have changed since you married.

A postnuptial agreement can cover:

  • Property and real estate

  • Savings and investments

  • Business assets and shareholdings

  • Pensions

  • Debts and liabilities

  • Future financial responsibilities

It cannot override arrangements relating to children in a way that would prevent a court from considering their best interests.

The key difference is timing. A prenuptial agreement is entered into before marriage or civil partnership, while a postnuptial agreement is made afterwards.

Both documents serve a similar purpose: to provide clarity and protect assets. If you did not put a prenuptial agreement in place before your wedding, a postnup can still achieve many of the same objectives.

The timescale depends on the complexity of your financial arrangements and how quickly financial disclosure can be exchanged. On average, the process may take several weeks.

We aim to manage the process efficiently and sensitively, ensuring both parties have time to take independent advice and feel confident in the final agreement.

Yes. A postnuptial agreement can be reviewed and updated if your circumstances change, for example, following the birth of a child, the sale of a business, or a significant inheritance.

We recommend reviewing your agreement periodically to ensure it remains fair and relevant.

The cost of a postnuptial agreement will depend on the complexity of your finances and the level of negotiation involved. At Tees, we provide clear, transparent information about fees at the outset.

If you are considering a postnuptial agreement, our experienced family law team would be happy to discuss your circumstances and guide you through the process with discretion and care.
