Key facts (2026): Common law marriage has no legal basis in England and Wales. Regardless of how long a couple has lived together, cohabiting partners have no automatic right to each other's property, pension, or assets on separation or death. This is a widely held myth with serious financial consequences for millions of UK couples.
An estimated 3.6 million couples in the UK cohabit without being married or in a civil partnership. A significant proportion believe they have legal rights as common law spouses — they do not. This misconception is one of the most financially dangerous myths in UK family law.
The Legal Reality of Cohabitation
In England and Wales (and in Northern Ireland), there is no such thing as a common law marriage. No matter how long a couple has lived together, they do not acquire automatic rights to each other's property or financial assets on separation. This is fundamentally different from Scotland, where some cohabitation rights exist under the Family Law (Scotland) Act 2006, and from many other countries where long-term cohabitation does create legal rights.
What Rights Do Cohabiting Couples Actually Have?
Cohabiting couples have rights only over property they jointly own (through a deed of trust or joint ownership), assets in their own name, and children (parental responsibility if on the birth certificate or through a parental responsibility agreement). If the relationship ends, the non-owning partner has no automatic right to share in property owned solely by the other — even if they contributed to mortgage payments or lived there for decades.
How to Protect Yourself as a Cohabiting Couple
The most effective protections are: a cohabitation agreement (also called a living together agreement) setting out how property and finances will be handled; a declaration of trust for any jointly purchased property specifying ownership shares; making a will — without one, a cohabiting partner has no automatic inheritance rights; and considering whether to marry or enter a civil partnership if long-term commitment and financial protection are priorities.
Our Verdict
The myth of common law marriage causes genuine financial hardship every year in the UK when long-term relationships end. If you cohabit, take legal steps to protect yourself: make a will, consider a cohabitation agreement for shared property, and understand that length of relationship confers no automatic legal rights in England and Wales. This is not about pessimism — it is about financial reality.
