The legal rights of unmarried couples, regarding property.

Unmarried Couples and Property Rights After Separation

When an unmarried couple separates, the legal position can be very different from that in a divorce or a civil partnership dissolution. Many people believe that living together creates "common-law marriage" rights, but that is not the law in England and Wales.

If a couple are not married or in a civil partnership, property disputes are usually dealt with under property and trust law rather than the family court's wider divorce powers. This can make the outcome more uncertain, especially where only one person is named as the legal owner of the home.

If the Property Is in One Person's Name

If the home is legally owned by only one partner, the other partner does not automatically acquire a share simply because they lived there, paid bills, cared for children or were in a long relationship.

However, the non-owning partner may still have a claim in some circumstances. This usually depends on whether they can show a beneficial interest in the property or another legal basis for compensation or occupation rights.

Beneficial Interests

A beneficial interest means a financial or equitable interest in the property, even though the person is not named as the legal owner. This may arise where there was a common intention that both partners would share the property and the non-owner acted to their detriment because of that understanding.

Evidence may include direct contributions to the purchase price, mortgage payments, substantial renovation work, written messages, discussions about ownership, financial arrangements, or other conduct showing that both parties intended the non-owner to have an interest.

Constructive Trusts

A constructive trust may arise where the court finds a shared intention that both partners should have an interest in the property and that it would be unfair for the legal owner to deny that interest.

These cases are highly fact-specific. The court will consider what was said, what was done, how the property was paid for, how finances were arranged and whether the non-owner relied on the shared understanding to their disadvantage.

Proprietary Estoppel

Proprietary estoppel may apply where one partner made a clear assurance or promise about the property, the other partner relied on that assurance, and it would be unfair to go back on it.

For example, a person may have given up their own home, invested money, carried out significant work or made life decisions because they were assured that they would have a home or a share in the property. If the court accepts the claim, it may award a remedy to reflect the unfairness.

If the Property Is Jointly Owned

If both partners are named as legal owners, the starting point will depend on how the property is owned. Joint tenants are usually treated as owning the property equally. Tenants in common may own specified shares, which may be equal or unequal.

A declaration of trust can be important because it records the intended shares. Without clear written evidence, disputes can arise about deposits, mortgage payments, family gifts, renovations and what each person should receive if the property is sold.

Paying Bills Does Not Always Create Ownership

Paying household bills, food, utilities or general living costs does not automatically give someone a share in a property. Courts are usually more interested in contributions to the purchase price, mortgage, substantial improvements or evidence of a clear agreement about ownership.

That said, every case depends on its facts. Wider financial arrangements may still be relevant where they help show what the couple intended.

Children and Housing

Where the couple have children, the legal position may be affected by the need to provide housing or financial support for the child. Claims may sometimes be made under Schedule 1 to the Children Act 1989, although these are claims for the benefit of the child rather than a general division of assets between the adults.

Child maintenance, living arrangements, and housing needs should be considered separately from property ownership. A family solicitor can advise on the correct route.

Cohabitation Agreements

Unmarried couples can reduce uncertainty by making a cohabitation agreement. This can set out who owns what, how bills and mortgage payments will be handled, what will happen if the relationship ends, and how property, savings, debts, or pets should be handled.

A cohabitation agreement is especially useful when one person owns the property, one partner contributes more to the deposit, parents are helping financially, or the couple wants to avoid future disputes.

Declaration of Trust

Where a couple are buying a property together, or one person is contributing to a property owned by the other, a declaration of trust can record the ownership shares and what should happen on sale.

This can be particularly important if deposits are unequal, one person is paying more of the mortgage, or a family member has provided a gift or loan.

Wills and Inheritance

Unmarried partners do not automatically inherit in the same way as spouses or civil partners. If one partner dies without a will, the surviving partner may receive nothing under the intestacy rules, even if they lived together for many years.

Cohabiting couples should consider making wills and reviewing life insurance, pension nominations, and property ownership arrangements. This is especially important where there are children, previous relationships or unequal financial contributions.

Current Reform Proposals

The law on cohabitation rights has long been criticised as uncertain and unfair. In 2026, the government launched a consultation on reforms that may give some cohabiting partners stronger financial rights when relationships end.

Until the law changes, unmarried couples should not assume that they have the same protection as married couples or civil partners. Written agreements and early legal advice remain important.

When Legal Advice May Be Needed

Legal advice may be needed when an unmarried couple separates, and there is a dispute over the family home, mortgage payments, deposits, renovations, promises made, children's housing needs, occupation of the property, or sale proceeds.

A solicitor can advise on beneficial interests, constructive trusts, proprietary estoppel, declarations of trust, cohabitation agreements, Schedule 1 Children Act claims and court applications under the Trusts of Land and Appointment of Trustees Act 1996.

Current Position

Unmarried couples do not automatically have the same property and financial rights as married couples or civil partners. A person not named on the title deeds may still have a claim in some circumstances, but they will usually need evidence of contributions, promises, shared intentions or reliance.

The safest approach for couples living together is to record their intentions clearly in a cohabitation agreement, a declaration of trust, and properly drafted wills.
