Many couples who live together believe they have the same legal rights as married partners. Unfortunately, this is not the case. Below, we debunk common myths and offer practical advice on how to protect your assets, your children, and your future.
Legal reform on the horizon?
The UK government is expected to launch a formal consultation on cohabitation laws in Spring 2026. The aim is to improve legal protections for unmarried couples, especially when relationships break down. However, similar reforms have been proposed in the past without resulting in meaningful change.
Common misconceptions
- “Common Law Marriage” is a myth
There is no such thing as a common law marriage in UK law. Living together does not grant you the same rights as being married. - No automatic rights to income, assets or pensions
Unmarried partners do not have automatic claims to each other’s income, property, or pension upon separation or death. - Property ownership matters
If a property is legally and beneficially owned by one partner, the other has no automatic claim to it. - No personal maintenance rights
Cohabitants cannot claim maintenance for themselves, regardless of how long the relationship lasted.
What financial claims are possible?
While rights are limited, there are some legal avenues available:
- Property claims
A partner may claim an interest in property if they can prove a ‘common intention constructive trust’ (CICT) or ‘proprietary estoppel’.- CICT is a trust that arises when it’s unfair (unconscionable) for a legal owner to deny another person a share (beneficial interest) in property, because they shared an understanding (common intention) that both would have a stake, and the other person acted to their detriment relying on that promise, often seen in cohabiting couples where property is in one name. It requires proving (1) a common intention (express or inferred) for shared ownership and (2) detrimental reliance on that intention, like financial contributions or significant life sacrifices.
- Proprietary estoppel is a legal principle that stops someone from going back on a promise they made about property or land where someone else has relied on that promise to their significant disadvantage. It is a court’s way of intervening to ensure fairness (equity) when a strict application of the law would be unjust.
- Child-related financial provision
Claims can be made for:- Property settlement
- Lump sum payments
- Additional child support (if the non-resident parent earns over £156,000 per year)
- Claims against a deceased partner’s estate
If statutory criteria are met, a surviving partner may claim reasonable financial provision from the estate.
Protecting yourself and your family
To safeguard your interests:
- Consult a family lawyer
Consider a cohabitation agreement to set out financial arrangements and responsibilities. - Understand your rights
Get legal advice tailored to your situation, especially if children are involved. - Communicate and document
Discuss expectations with your partner and record any agreements in writing.
