Marital Rights vs Co-habiting Rights: What’s the Legal Difference?

There is a lot of confusion about the difference between marital rights and cohabiting rights. Married couples have clear legal protections and duties, while cohabiting couples do not get the same automatic rights, however long they live together. That gap changes everything about how property, money and support are handled if a relationship ends, or if one partner dies. This guide explains what marital rights are, what legal rights cohabiting couples actually have, the myth of common law marriage, and the reform the government is now consulting on.

What Are Marital Rights?

Marital rights are the legal protections and obligations that come automatically with marriage or civil partnership in the UK. When a couple marries, they enter a legally binding relationship that gives each of them rights over the other’s assets and a duty to support each other. If the marriage ends, the court divides the couple’s assets fairly under the Matrimonial Causes Act 1973, weighing factors such as the length of the marriage, each person’s needs, and the contributions each made.

In practice, marital rights usually cover:

• A share of assets: property, savings, investments and pensions can all be divided, whoever legally owns them.
• Spousal maintenance: ongoing financial support where one partner earns significantly more than the other.
• Inheritance and next of kin: a spouse inherits automatically if the other dies without a will, and is treated as next of kin.
• Tax protection: transfers of assets between spouses are generally free of capital gains tax and inheritance tax.

Arrangements for children are decided in the same way whether parents are married or not, based on the child’s best interests. Both parents have a duty to support their children financially, and that duty continues after any separation.

What Legal Rights Do Cohabiting Couples Have?

Cohabiting couples do not have the automatic protections that married couples have. If they separate, the law treats them as two individuals rather than a couple. Each person keeps the assets and property they brought into the relationship, and anything held jointly is usually treated as owned equally, but there is no automatic right to claim a share of a partner’s assets.

That makes separation for cohabiting couples surprisingly complicated. Disputes have to be resolved through negotiation, family mediation or court, and there is no spousal maintenance and no claim on a partner’s pension. Where there are children, each parent still has a duty to support them, but there is no financial support for the other partner beyond child maintenance. In limited cases a parent can bring a claim for a child under Schedule 1 of the Children Act 1989, for things like housing or school fees, and it is worth taking legal advice before doing so.

Is There Such a Thing as Common Law Marriage?

No. This is one of the most damaging myths in family law. There is no such thing as common law marriage in England and Wales, and there has not been for centuries. Living together for a long time, sharing a home, having children together or taking a partner’s surname does not create marriage-like rights. You can find clear guidance on the differences at Citizens Advice.

Many people only discover this at the worst possible moment, when a relationship ends or a partner dies. Believing you are protected when you are not can leave you with no claim to a home you helped pay for, or nothing at all if your partner dies without a will. This is exactly why understanding the difference between marriage and cohabitation matters so much.

What Is the Difference Between Marriage and Cohabitation?

Here is a side-by-side comparison of how the law treats married couples and cohabiting couples in England and Wales:

The clearest way to see it: for children, marriage makes no difference, but for money, property and inheritance between the adults, it makes a very big one.

How Are a Cohabiting Couple’s Property Rights Decided?

Because family law does not divide a cohabiting couple’s assets, property rights of cohabiting couples are worked out under property and trust law instead, mainly the Trusts of Land and Appointment of Trustees Act 1996, usually shortened to TOLATA. The key question is who owns the property and in what shares.

• Joint legal owners: if you both own the home, it usually comes down to how you hold it and any declaration of trust you signed.
• Sole legal owner: if only one partner is on the title, the other may still claim a share, but has to prove a beneficial interest, for example through financial contributions or a shared intention.
• Declaration of trust: a document that records each person’s share, which removes most of the uncertainty if you separate.

TOLATA disputes can be stressful and expensive, so it is well worth trying to agree things through mediation and recording the outcome clearly.

How Can Cohabiting Couples Protect Themselves?

Until the law changes, cohabiting couples have to create their own protection. There are four practical steps:

• A cohabitation agreement: sets out who owns what and what happens if you separate, giving both of you clarity.
• A declaration of trust: records your shares in a jointly owned home.
• A will: without one, your partner inherits nothing, so a will is essential for unmarried couples.
• Life insurance and pension nominations: naming your partner makes sure they are provided for.

If you do separate, you can record what you agree in a separation agreement. Our guide to the 11 ways to reach a financial settlement sets out the options for married and unmarried couples alike.

Will the Law on Cohabiting Rights Change?

It may do. Reform has been talked about for years, and pressure has grown as cohabiting couple families have become the fastest growing family type in the UK. According to the Office for National Statistics, there were around 3.6 million opposite-sex cohabiting couple families in 2022, about 18% of all families, up from 16% a decade earlier.

In 2026 the government launched a consultation called A fairer end to relationships, which includes proposals to give cohabitants who separate a new statutory right to make financial claims, likely where they have lived together for a minimum period or have a child together, along with stronger inheritance rights if a partner dies without a will. As of July 2026 this is only a consultation. Nothing has changed in law, and any reform could take a long time to arrive, so it is still wise to protect yourself now rather than wait.

How Can Mediation Help?

Whether you are married or cohabiting, mediation is usually quicker, less expensive and less stressful than going to court, and it lets you keep control of the outcome. A mediator can help you agree how to divide property, sort out arrangements for the children, and record everything clearly, whether that becomes a consent order for a married couple or a separation agreement for a cohabiting one. For child arrangements there is also the government family mediation voucher scheme, a one-off contribution of up to £500 per family, which is not means-tested.
