Cohabitation Rights UK - Do Unmarried Couples Have Legal Rights?

More couples in England and Wales live together without marrying or entering a civil partnership than ever before, yet the law has not kept pace with how people actually live. Many cohabiting partners assume that living together for years, buying a home, or having children together gives them the same legal protection as a married couple. It does not. This guide explains what rights unmarried couples really have in 2026, the risks of doing nothing, and the practical steps you can take to protect yourself, your home, your children and your finances.

The information below reflects the law in England and Wales. Scotland and Northern Ireland have different rules. If you are cohabiting, thinking of moving in together, or separating from a partner you were not married to, speak to a family solicitor about your own circumstances.

The "common law marriage" myth

There is no such thing as common law marriage in England and Wales, and there has not been for centuries. No matter how long you live together, whether you share a surname, whether you have children, or whether you describe each other as husband, wife or partner, you do not acquire the legal status of a married couple simply by cohabiting.

This matters because the rights that flow from marriage or civil partnership, such as automatic financial claims on separation, spousal maintenance, an automatic share of a pension, and automatic inheritance on death, do not apply to cohabitants. The phrase "common law wife" or "common law husband" has no legal meaning. Believing otherwise is one of the most common and most costly misunderstandings we see.

What rights do cohabiting couples actually have?

Cohabitants are treated by the law largely as two separate individuals. Rather than a single family law framework, your position is governed by a patchwork of general laws covering property, trusts, children and inheritance. In broad terms:

• You have no automatic right to a share of property owned in your partner's sole name, unless you can establish a legal or beneficial interest.
• You have no right to maintenance for yourself if you separate, however long you lived together or however financially dependent you were.
• You have no automatic right to inherit if your partner dies without a will.
• You may have rights and responsibilities in relation to your children, which are separate from your rights as a couple.
• Anything you own jointly, or can prove you contributed to, may give rise to a claim.

Because so little is automatic, the documents you sign and the arrangements you put in place carry enormous weight. This is why proactive legal planning is far more important for cohabitants than for married couples.

The family home: who owns what?

For most couples the family home is the biggest asset and the biggest source of dispute on separation. Your position depends heavily on how the property is owned on paper.

If you are joint legal owners

If you both appear on the title at the Land Registry, you both have a legal interest in the property. How the beneficial ownership is split depends on whether you hold as joint tenants or as tenants in common:

• Joint tenants own the whole property together. If one of you dies, the survivor automatically inherits the deceased's share by survivorship, regardless of any will. On separation the starting point is usually a 50/50 split.
• Tenants in common each own a distinct share, which can be equal or unequal, for example 60/40. Each person's share passes under their will or the intestacy rules, not automatically to the survivor.

The best way to avoid argument is a declaration of trust (sometimes recorded on the Land Registry TR1 form or in a separate deed) setting out exactly what each of you owns. Where the paperwork clearly records your shares, the courts will generally give effect to it.

If the home is in one partner's sole name

This is where cohabitants are most exposed. If the property is owned solely by your partner, you have no automatic interest simply because you lived there or contributed to household costs. To claim a share you would generally need to establish a beneficial interest under trust law.

Claims of this kind are usually brought under the Trusts of Land and Appointment of Trustees Act 1996 (often called TOLATA). To succeed you typically need to show either an express agreement about ownership, or a common intention that you would share the property together with conduct such as significant financial contributions on which you relied to your detriment. The leading cases in this area, including Stack v Dowden (decided by the House of Lords) and the later Supreme Court decision in Jones v Kernott, show how fact-sensitive and complex these disputes can be.

These claims are notoriously difficult, expensive and uncertain. Paying rent, buying furniture or contributing to the weekly shop will not usually be enough. Direct contributions to the deposit or mortgage, or a clear agreement, carry far more weight. If you are moving into a home owned by your partner, take advice before you contribute money.

Financial claims on separation

When a marriage ends, the court has wide powers to redistribute property, order lump sums, share pensions and award maintenance to achieve fairness. None of these powers apply to cohabiting couples. There is no equivalent to a divorce financial settlement for people who were not married or in a civil partnership.

On separation, a cohabitant can generally only pursue claims based on:

• Property and trust law, to establish or realise an interest in a home or other asset (for example a TOLATA claim).
• Provision for the benefit of any children (see below).
• Assets that are genuinely jointly owned, such as a joint bank account or jointly held property.

There is no right to ongoing maintenance for an ex-partner, no automatic pension sharing, and no claim simply because one of you gave up work or earned far less during the relationship. A partner who stayed at home to raise children or support the other's career can be left in a very difficult financial position. This is one of the strongest reasons to plan ahead with a cohabitation agreement.

Children: maintenance and provision

Your rights and responsibilities towards children are separate from your rights as a couple, and here the law does provide meaningful protection.

Parental responsibility

A mother automatically has parental responsibility. An unmarried father usually acquires parental responsibility by being named on the child's birth certificate (for births registered in England and Wales from December 2003), or by a parental responsibility agreement or court order. Parental responsibility affects decisions about the child's upbringing, not who the child lives with.

Child maintenance

Both parents are financially responsible for their children regardless of marital status. Child maintenance is normally arranged either privately between the parents or through the Child Maintenance Service (CMS), which calculates payments based on the paying parent's income and other factors. You can use the calculator and check the current rules on gov.uk.

Schedule 1 to the Children Act 1989

Beyond regular child maintenance, a parent can apply to the court under Schedule 1 to the Children Act 1989 for financial provision for the benefit of a child. This can include a lump sum, payment of certain expenses, or provision of a home for the child to live in with the primary carer until the child reaches adulthood or finishes education. Importantly, any housing provided this way usually reverts to the paying parent once the child is grown, rather than transferring outright. These orders are for the child's benefit, not the parent's, but they can be a vital source of support for a cohabiting parent who is the main carer.

What happens if your partner dies?

Death is where the lack of legal status can be most devastating for cohabitants.

Intestacy: no automatic inheritance

If your partner dies without a valid will, the intestacy rules decide who inherits, and a surviving cohabiting partner is not included, no matter how long you were together. The estate passes to spouses, children or other blood relatives. A cohabitant can be left with nothing, and could even face losing their home if it was owned by their late partner and passes to someone else.

The Inheritance (Provision for Family and Dependants) Act 1975

A surviving cohabitant may be able to bring a claim under the Inheritance (Provision for Family and Dependants) Act 1975 for reasonable financial provision from the estate. Broadly, you may qualify if you lived with the deceased as a couple in the same household for at least the two years immediately before the death, or if you were being financially maintained by them. These claims are subject to strict time limits, usually within six months of the grant of probate, and the outcome is not guaranteed. It is far better to make a will than to rely on litigation after a death.

The "next of kin" myth

Being someone's partner does not automatically make you their next of kin for legal purposes, and it does not give you the right to make medical or end-of-life decisions on their behalf. To have a formal say if your partner loses capacity, you would need to be appointed under a Lasting Power of Attorney.

Pensions, tax and benefits

• Pensions: Many pension schemes allow you to nominate a beneficiary for death benefits, but the rules vary. Some occupational and public sector schemes have historically restricted survivor benefits for unmarried partners, and payment of discretionary death benefits may depend on you having completed an up-to-date nomination form. Check your scheme rules and keep your nomination current.
• Inheritance tax: The spouse and civil partner exemption, which allows assets to pass between them free of inheritance tax, does not apply to cohabitants. Assets passing to a surviving partner may therefore be taxed, and the transferable nil-rate band available to married couples is not available. Take specialist advice on estate planning, as thresholds and reliefs can change; check the current figures on gov.uk.
• Benefits: For means-tested benefits and tax credits, couples who live together as if married are generally assessed jointly on their combined income and capital, in the same way as married couples. So while cohabitants miss out on many of the advantages of marriage, they are still treated as a couple when it comes to benefit entitlement.

How to protect yourself: practical steps

Because so little is automatic, the single most valuable thing cohabiting couples can do is put clear arrangements in place while the relationship is healthy. We recommend considering the following.

A cohabitation agreement

A cohabitation agreement (sometimes called a living together agreement) is a written record of how you will manage your finances during the relationship and how property, savings, debts and belongings will be divided if you separate. A properly drafted agreement, entered into freely with each partner having taken independent legal advice and made full financial disclosure, can carry significant weight and greatly reduce conflict and cost later on. It can cover the home, contents, joint accounts, debts, and arrangements for any children.

A declaration of trust

If you own property together, or one of you is contributing to a home owned by the other, a declaration of trust records exactly what share each person owns and how sale proceeds will be divided. This is one of the most effective ways to avoid an expensive TOLATA dispute in the future.

Make a will

Because a cohabiting partner does not inherit automatically, a valid, up-to-date will is essential. It lets you provide for your partner, protect your children, and set out who should deal with your estate, avoiding the intestacy rules altogether.

Lasting Powers of Attorney

Consider making Lasting Powers of Attorney for both finances and health and welfare, appointing your partner (or someone you trust) to act for you if you lose capacity. Without one, your partner has no automatic authority to manage your affairs or be involved in medical decisions.

Review joint ownership, life cover and nominations

Check how your home is owned, keep pension death-benefit nominations up to date, and consider life insurance written in trust so that a payout goes quickly to your partner rather than being tied up in your estate.

Is the law going to change?

Reform of cohabitation law has been debated for many years, and organisations including the Law Commission have recommended giving cohabitants greater protection on separation and death. As of 2026 the fundamental position in England and Wales remains unchanged: cohabiting couples still do not have the same rights as married couples, and "common law marriage" is still a myth. Until Parliament changes the law, you should plan on the basis of the rules as they stand today, not the rules you might wish existed.

Frequently asked questions

Does living together for a long time give me the same rights as being married?

No. There is no common law marriage in England and Wales. However long you cohabit, you do not gain the legal status or automatic financial and inheritance rights of a married couple. Your rights depend on property law, any agreements you have made, and your children, not on the length of the relationship.

Can I claim a share of a house that is only in my partner's name?

Possibly, but it is not automatic. You would generally need to establish a beneficial interest under trust law, usually through a TOLATA claim, by showing an agreement to share the property or significant financial contributions you relied on. These claims are complex and uncertain, which is why a declaration of trust agreed in advance is so valuable.

Am I entitled to maintenance from my ex-partner if we split up?

No. Unlike divorcing spouses, cohabitants have no right to spousal maintenance for themselves, regardless of financial dependence or the length of the relationship. You can, however, seek child maintenance and, in some cases, financial provision for the benefit of your children under Schedule 1 to the Children Act 1989.

Will I inherit if my partner dies without a will?

Not automatically. Under the intestacy rules a surviving cohabitant is not entitled to inherit. You may be able to bring a claim under the Inheritance (Provision for Family and Dependants) Act 1975 if you lived together for at least two years before the death or were financially maintained, but this is subject to strict time limits and is not guaranteed. Making a will is by far the safer option.

Is a cohabitation agreement legally binding?

A well-drafted cohabitation agreement, signed freely by both partners with independent legal advice and full financial disclosure, is generally treated by the courts as a valid contract and given significant weight. It is one of the most effective ways to set out how your finances and property will be dealt with and to avoid costly disputes if you separate.

Do my children have any protection if their parents are not married?

Yes. Children's rights do not depend on whether their parents were married. Both parents are financially responsible for their children, child maintenance can be arranged through the Child Maintenance Service, and the court can order further financial provision for a child under Schedule 1 to the Children Act 1989, including provision of a home during the child's minority.
