Common law marriage UK: the myth and your rights as a cohabiting couple

Did you know that “common law marriage” is not recognised in England and Wales? Living together does not give you the same legal rights as marriage. This can become especially difficult during a breakup or after a death, particularly around property or childcare. Knowing this early helps you put protections in place before problems arise. If you are facing a dispute, find a specialist family solicitor to protect your interests. To protect yourself early on, look into getting a cohabitation agreement.

Key Takeaway: Are you legally married if you live together in the UK?

No. “Common law marriage” is a myth in England and Wales. Living together does not grant the same legal rights as marriage, regardless of time spent together or having children.

To protect your future, know where you stand:

• The Reality: Cohabiting couples lack automatic legal protections.
• Resolve Disputes: Facing a breakup? Find a family solicitor to protect your interests.
• Secure Your Future: Get a cohabitation agreement to avoid uncertainty.

Debunking the common law marriage UK myth

The Reality of Living Together

• No legal status: “Common law marriage” is a myth in UK law. No matter how long you live together, you are legally considered “cohabitants.”
• No automatic rights: If you separate, you have no automatic claim to a “fair” division of assets, the family home, or your partner’s pension.
• Complex laws: Unlike divorce courts—which split assets fairly—unmarried couples must rely on complex property and trust laws to sort out ownership.

How to Protect Yourself

• Cohabitation Agreement: You can sign a legal “living together agreement” to clearly state who owns what and how assets should be split if the relationship ends.

Property rights and the role of TOLATA for unmarried couples

For many unmarried couples, property rights are the main issue on separation. If the home is in one partner’s sole name, the other may have no automatic right to stay or to a share of the sale proceeds.

Disputes are usually resolved under the Trusts of Land and Appointment of Trustees Act 1996 (TOLATA). The non-owner must prove a beneficial interest in the property. For a detailed breakdown of how a cohabitation agreement protects your property rights, see our dedicated guide on the subject.

This generally requires evidence such as:

• Financial contribution to the purchase or mortgage
• A shared intention to own the property together
• Detrimental reliance (e.g. paying for major improvements)

Occupancy rights are also limited. A sole owner or tenant can usually ask a partner to leave, unless a court grants short-term protection such as an occupation order in cases involving domestic abuse.

Case Study Scenario:

Consider a couple where the house is in the name of the man. The woman pays for a new kitchen and the conservatory, believing they are sharing the home. If they split, the man claims the house is entirely his. Under TOLATA, the woman must provide evidence of her contributions and any discussions they had about ownership to claim her share. Without a written declaration of trust, this process is expensive and uncertain.

Parental responsibility and financial provision for children

Unmarried couples often misunderstand their rights regarding children. Both parents must support their child financially, but legal rights differ, particularly when it comes to a father’s rights and parental responsibility for unmarried fathers.

Parental responsibility:

• Mother: automatic parental responsibility
• Father: only automatic if married or named on the birth certificate (post-1 Dec 2003, England & Wales)

After separation:

• Non-resident parent must pay child maintenance
• Decisions on schooling, healthcare, religion depend on parental responsibility

Court support (Children Act 1989, Schedule 1):

• Financial provision may be ordered
• Includes lump sums or property for the child’s benefit until age 18

Banking, joint accounts, and managing debts

Managing finances as a couple requires planning.

Bank accounts:

• Separate accounts: your partner has no access; on death, funds go into your estate (will or intestacy laws)
• Joint account: both partners can access all funds
• On separation, courts may decide how to split it
• If one partner did not contribute, their claim may be weaker

Debts:

• Individual debts: only the named person is liable
• Joint debts (mortgage, council tax): both are fully liable (“jointly and severally”)
• A creditor can pursue either partner for the full amount

Death and inheritance: Why unmarried partners are at risk

Unmarried partners have no automatic inheritance rights in England & Wales.

If a partner dies intestate (no will):

• The surviving partner inherits nothing automatically
• Estate passes to children, then parents, then siblings

You only inherit if:

• Property is held as joint tenants (automatic transfer to survivor)
• You are named in a valid will

Possible legal claim:

• Inheritance (Provision for Family and Dependants) Act 1975
• Must have cohabited with the deceased for at least two years immediately before the death (under s.1(1A) Inheritance (Provision for Family and Dependants) Act 1975); claims are costly and uncertain

Tax:

• No inheritance tax exemption for unmarried couples
• Married couples/civil partners have tax advantages that cohabitants do not

The 2025 Law Commission recommendations and the 2026 legal landscape

Cohabitation law in England & Wales is widely seen as outdated.

• Scotland has had limited protections since 2006 (e.g. financial claims on separation)
• England & Wales still do not recognise “common law marriage”

Recent developments:

• Law Commission work (2025) and a government report (Feb 2026)
• Recognition that the “common law marriage” belief is a misconception
• Ongoing consultation on reform

Proposed reforms:

• Court powers to make financial orders on separation
• Better inheritance protection for surviving cohabitants
• Clearer rules on “next of kin” for medical/emergency decisions

Current law (2026):

• No automatic rights for unmarried partners
• Legal protection depends on agreements (e.g. declaration of trust, cohabitation agreement)

FAQs

What rights do unmarried couples have?

Unmarried couples have very limited automatic rights. Assets usually belong to whoever is named on them, and claims over a partner’s property must be proven through trust law or legal agreements.

How long do you have to live together to be common law?

There is no “common law marriage” in England and Wales. Living together for any length of time does not create legal rights or change your status.

What happens if unmarried couples split up?

Each person usually keeps what they own. Joint assets are divided by agreement or court order. There is no automatic right to financial support as in divorce.

Are you legally recognised as a next of kin if you are not married?

“Next of kin” has no strict legal definition. A partner may be recognised informally, but this is not guaranteed. A Lasting Power of Attorney is recommended for legal decision-making rights.

The myth of “common law marriage” continues to leave many people in the UK at financial risk. Cohabitation does not create legal rights, even after many years. Unmarried couples should plan ahead. A will or cohabitation agreement is often needed to protect assets and children.

KEY TAKEAWAYS:

• Common law marriage is a myth in England and Wales, regardless of how long you live together.
• Property rights are not automatic and may require proving a beneficial interest under TOLATA.
• Unmarried partners do not inherit without a will — assets go to next of kin.
