What Is a Cohabitation Agreement?
A cohabitation agreement is a practical, legally binding document designed specifically for unmarried couples who live together. It clearly records what you have agreed regarding property rights, daily household expenses, savings and debts.
Despite widespread myths, there is no such thing as a “common law marriage” in England and Wales. No matter how many years you spend together, or whether you have children, living under the same roof does not grant you the automatic legal protections of a spouse. If the relationship ends without an agreement, the law simply looks at who legally owns what and who paid for what. This is a harsh framework that leaves thousands of people compromised and blindsided.
A cohabitation agreement changes that. It allows you to protect your individual assets. This may be a house deposit or an inheritance, while establishing a fair, transparent plan for your shared life.

Property Rights and the Cohabitation Trap
When a relationship breaks down, the property rights that unmarried couples have are incredibly limited. If the family home is held in your partner’s sole name, you have no automatic right to a share of its value. This is even if you contributed to the mortgage or put years of work into maintaining it.
To fight for a share of a solely owned property after a split, you have to launch complex, highly expensive claims under trust and land law (such as TOLATA). You have to prove exactly what was promised or show direct financial contributions to the purchase. A cohabitation agreement bypasses this entire legal minefield by setting your property arrangements down in black and white from the very beginning.
The 2026 Reforms and Why You Must Act Now
The government has launched a major consultation aimed at introducing a safety net for the cohabitation rights in the UK framework. Under these proposals, unmarried couples who live together for three years, or who share a child, could automatically gain certain financial claims if they separate.
However, nothing has changed yet. These are just proposals, and any actual legislation is likely years away from reaching the statute books. Furthermore, the government’s proposed framework explicitly includes an “opt-out” mechanism. This allows couples to override the default law with their own private agreement. Whether you need to shield yourself from the current total lack of rights or want to dictate your own financial terms ahead of future law changes, a cohabitation agreement remains your single most powerful shield.

FAQs
What are cohabitation rights in the UK?
At present, unmarried couples have virtually no automatic cohabitation rights UK law recognises. Living together does not give you a claim over your partner’s property, savings, or pension, and you cannot claim spousal maintenance if you separate.
What property rights do unmarried couples have?
Property rights that unmarried couples hold depend entirely on whose name is on the legal title deeds. If the house is in your ex-partner’s sole name, you have no automatic right to its value. This is regardless of how long you lived there or what you contributed to the household bills.
What does a cohabitation agreement do?
A cohabitation agreement sets out clear, legally binding rules about how your assets, debts and finances are handled during the relationship. It works out exactly how they will be divided if you separate. It covers mortgage payments, rent, utility bills, savings and ownership of property.
Is a cohabitation agreement legally binding?
Yes. Provided it is drafted correctly and signed voluntarily by both parties. It must feature full financial disclosure. A cohabitation agreement is treated as a binding contract in England and Wales.
Does McKenzie Picave draft cohabitation agreements?
No. A cohabitation agreement requires a specialist legal professional or specialised provider to ensure it is structurally watertight. McKenzie Picave provides expert McKenzie Friend court support and strategic case preparation for litigants in person if a dispute has already reached the family or civil courts.
What happens if we separate without an agreement?
If you separate without an agreement, you must rely on complex property and trust laws to claim a share of any assets held in your partner’s name. This process is notoriously expensive and stressful. It is entirely dependent on providing strict historical evidence of financial contributions or promises.
