Cohabitation Agreements

Why Consider a Cohabitation Agreement?

March 27, 2026•2 min read

1. Avoiding disputes further down the line

If a relationship ends, disagreements about money and property can become stressful and expensive.

A well-prepared cohabitation agreement sets out in advance who owns what and what should happen if you part ways. This can significantly reduce the risk of costly legal disputes.

Couple reviewing cohabitation agreement documents together at a table, focusing on financial arrangements and shared responsibilities

For example, it can explain:

  • Whether the property should be sold

  • Who can stay in the home and for how long

  • How the property will be valued

  • How sale proceeds will be divided

Having these conversations early when things are amicable can make a difficult situation much easier to manage later.

2. Flexibility and control

Unlike married couples, people who live together do not automatically have legal rights to financial support or to share in each other’s assets if the relationship ends.

A cohabitation agreement allows you to decide for yourselves what feels fair.

For instance, some couples choose to include arrangements for financial support after separation, particularly where children are involved or one person may need time to regain financial independence.

3. Protecting your investment

With property prices where they are, many people spend years saving for a deposit. Others rely on financial help from family.

It’s understandable that you may want to protect that investment.

A cohabitation agreement can:

  • Record how much each person has contributed

  • Protect money gifted or loaned by family

  • Ensure those contributions are recognised if the property is sold later

This is particularly common where parents have helped fund a purchase and want reassurance that the money is safeguarded.

4. Peace of mind after past relationships

If you have previously been married or in a civil partnership, you may be more aware of the financial consequences of separation.

Many people in this position use cohabitation agreements to:

  • Protect their financial stability

  • Ring-fence assets

  • Preserve funds for children or future inheritance

This outlines the key reasons why couples consider a cohabitation agreement and the practical benefits of putting one in place. The potential downsides and practical considerations are explored in the next part of this series.
