How Much Does a Cohabitation Agreement Cost
September 2025
More couples are choosing to live together without marrying, but this can leave them without automatic legal protection if the relationship ends. A cohabitation agreement is one way to give both partners clarity and security. Understandably, one of the first questions people ask is: how much does a cohabitation agreement cost in England and Wales?
This summary provides general information and does not constitute legal advice on any individual circumstances.
What Is a Cohabitation Agreement?
A cohabitation agreement is a written document between two people who live together but are not married or in a civil partnership. It sets out how property, finances, and responsibilities will be managed during the relationship and, importantly, what should happen if the couple separates. It can cover things such as who owns the home, how much each person contributed to the deposit, how bills will be shared, and how savings or possessions would be divided.
Why Cost Can Vary
The cost of a cohabitation agreement in England and Wales is not fixed. It depends on several factors, including how complex your financial arrangements are, whether there are children involved, and whether one or both of you owns property. Simple agreements are usually less expensive, while more detailed ones may cost more because they take longer to prepare and require more tailored legal advice.
Typical Costs
A straightforward agreement can often be prepared for a few hundred pounds. More complex arrangements, particularly where property, business interests, or significant savings are involved, may cost more.
Is It Worth the Cost?
Some couples are unsure whether a cohabitation agreement is worth the expense, especially if they feel their relationship is strong. However, without one, the financial consequences of a separation can be far more costly. Disputes about property ownership or deposits can run into thousands of pounds in legal fees and cause long delays. A well-drafted agreement can save money, time, and stress in the long run by providing clarity from the start.
The “Only for Wealthy Couples” Myth
It’s often assumed that cohabitation agreements are only useful for couples with large assets. In reality, they can benefit anyone who shares a home, contributes to a deposit, or pays bills together. Even modest contributions can be worth protecting.
Value Beyond Money
The value of a cohabitation agreement is not only financial. It also gives peace of mind. By putting arrangements in writing, both partners know where they stand, reducing the risk of misunderstandings. It can also provide reassurance for parents or family members who may have helped with a deposit and want to make sure their contribution is protected.
Reviewing and Updating
It is worth remembering that a cohabitation agreement is not a one-off document for life. If your circumstances change — for example, if you buy a new property, have children, or change how you share finances — the agreement should be updated. This ensures that it continues to reflect your situation and remains effective.
Looking Ahead
The cost of a cohabitation agreement depends on your circumstances, but the protection it provides is usually worth far more than the initial outlay. Rather than seeing it as an unnecessary expense, it can be helpful to view it as an investment in clarity, fairness, and peace of mind for both partners.
