Cohabitation Law Explained: Protecting Your Rights When Living Together

Did you know there’s no such thing as a “common-law husband or wife”?


This is one of the biggest myths in English law. If you live with your partner without marrying or entering a civil partnership, you do not have the same rights as a married couple – no matter how long you’ve been together.

This can come as a shock when relationships break down or if one partner passes away, often leaving the other in a financially vulnerable position.

What Are the Rights of Cohabiting Couples?

·       Property & assets – Unlike divorce, assets such as the family home are not automatically divided. Instead, complex trust and land law applies.

·       Finances & pensions – There is no automatic right to claim financial support, pension sharing, or spousal maintenance.

·       Children – The law treats married and unmarried parents the same when it comes to deciding where children live and how much time they spend with each parent.

The biggest difference between married and cohabiting couples is financial protection on separation – cohabitees have far fewer legal safeguards.

Property Disputes – Who Owns What?

When an unmarried couple splits up, the court will usually look at:

·       Any written agreement (e.g. declaration of trust) stating how the property should be owned.

·       The actions and intentions of the couple.

If there’s no written record, the partner claiming a larger share must prove it to the court – which is often very difficult.

Even if you paid the deposit or most of the mortgage instalments, you may only be entitled to half unless you can show there was an agreed arrangement in writing.

How to Protect Yourself as a Cohabiting Couple

The best way to safeguard your financial and family interests is to put clear agreements in place before problems arise. Options include:

·       Cohabitation Agreement – A legal document setting out how property, assets, finances, and childcare arrangements should be dealt with if you separate.

·       Declaration of Trust – Records how a property is owned (e.g. unequal shares) and what happens to equity if the relationship ends.

·       Wills & Life Insurance – Essential if you want to protect your partner and dependents financially.

Without these, you may be left relying on costly and uncertain court proceedings.
