In the UK, more and more couples are choosing to live together without getting married. But while cohabitation may feel just like marriage in day-to-day life, the legal picture is very different, especially when it comes to property.
So what actually happens to the house if you and your partner break up and you’re not married?
The short answer is: it depends on how the property is owned, and what can be proven.
First things first—you will need to check the title deeds or Land Registry documents. The legal ownership of the home will usually determine who has rights to it.
If only one partner is the legal owner, the other doesn’t automatically have a right to a share, even if they’ve contributed to bills or renovations. To claim an interest, the non-owning partner would need to prove:
- They were promised a share of the property, and
- They relied on that promise to their detriment (e.g. spent money on improvements, gave up work, or paid towards the mortgage)
This is known as a Trusts of Land (TOLATA) claim, and it can be complex, costly, and uncertain.
If you’re both listed as legal owners, your rights will depend on how you own it:
- Joint Tenants – You own the property equally. If you split, it’s assumed you’re each entitled to 50%, unless there’s evidence to the contrary.
- Tenants in Common – You each own a specific share (e.g. 70/30 or 60/40), which should be recorded in a Declaration of Trust or similar legal document.
If nothing is formally documented, the starting point is usually a 50/50 split—though this can be challenged if there’s strong evidence of a different intention.
Unfortunately, there’s no such thing as a “common law marriage” in England and Wales. Cohabiting couples do not have the same legal protections as married couples, no matter how long you’ve been together.
Paying utility bills or contributing to household expenses does not give you ownership rights unless there’s clear evidence you were promised a share or directly contributed to the purchase price or mortgage.
The best way to avoid uncertainty is to take proactive steps during the relationship:
- Cohabitation Agreement – Set out who owns what, who pays for what, and what happens if you separate.
- Declaration of Trust – Clearly define your shares in the property and how proceeds will be divided if sold.
- Seek legal advice before making big contributions (e.g. paying for renovations or mortgage) if your name isn’t on the deeds.
These documents provide clarity, prevent disputes, and protect both parties’ interests.
If one of you wants to keep the property or refuses to sell, and no agreement can be reached, you may need to apply to the court under TOLATA to resolve the dispute. The court can decide:
- Who owns what share
- Whether the house must be sold
- If one party is entitled to compensation
These cases can be complex, so it’s important to get advice early.
Breaking up is hard enough without the added stress of not knowing where you stand legally. If you’re not married and own (or live in) a property together, don’t leave your rights to chance.
