The number of cohabiting couples has risen sharply in recent years, while marriage rates have generally declined. Many couples now live together for years, share homes, raise children, and build a life that looks every bit as committed as a marriage.
The problem is that, in England and Wales, living together does not create a “common law marriage”. A long relationship, shared home, or children together does not automatically give unmarried couples the same legal rights as spouses or civil partners if the relationship ends or one person dies.
That misunderstanding still catches people out. Many cohabitees wrongly believe they have the same protections as married couples, when in reality the legal position is very different.
Key takeaways
- “Common law marriage” is a myth in England and Wales.
- Living together does not automatically give you the same rights as a spouse or civil partner.
- Cohabiting partners cannot usually claim financial support for themselves in the same way a spouse may be able to on divorce.
- Unmarried couples may still need legal advice about property, trusts, children, wills, inheritance planning, and legal agreements.
- A cohabitation agreement and clear legal protection can help reduce uncertainty and risk.

What does “common law marriage” actually mean?
In practice, it means a mistaken belief that if you live with your partner for long enough, the law will start to treat you as if you were married.
That is not how the law works in England and Wales.
There is no automatic point at which cohabitation turns into marriage in the eyes of the law. It does not matter whether you have lived together for two years, ten years, or longer. It does not matter whether you have children together. And it does not matter whether friends, family, or even the couple themselves refer to each other as husband and wife.
Without marriage or civil partnership, the legal position is fundamentally different.
That is why couples who live together without marrying should not assume the law will protect them in the same way. In many cases, putting a cohabitation agreement or other legal protection in place is far safer than relying on assumptions.
Why the myth is so risky
The phrase “common law marriage” sounds harmless, but it can lead people into making serious assumptions about what protection they have.
Someone may believe they:
- Have an automatic right to stay in a partner’s property
- Can claim financial support for themselves after separation
- Will inherit automatically if their partner dies
- Can claim against pensions in the same way as a spouse
- Will be treated fairly because they contributed informally over many years
That false sense of security can become a major problem when a relationship breaks down or one partner dies unexpectedly.
What rights do married couples have that cohabiting couples usually do not?
The difference is significant.
Where a couple are married or in a civil partnership, the law may provide routes to:
- Seek a financial settlement on separation or divorce
- Apply for spousal maintenance in appropriate cases
- Argue for a share of assets, including some assets held in one name only
- Benefit from certain inheritance rights
- Claim pension rights or widow’s benefits in some circumstances
By contrast, cohabiting couples do not acquire those rights simply by living together. They do not usually have any continuing legal obligation to support each other financially after separation, and they do not gain the same automatic inheritance position as spouses.
That does not mean unmarried couples have no legal position at all. It means their rights usually depend on different areas of law, and those routes are often narrower, more technical, and more fact-specific.
What legal rights can unmarried couples have?
Unmarried couples can still have legal disputes and legal claims, but those claims do not arise in the same way they can on divorce. The issues are more likely to involve property ownership, beneficial interests, financial contributions, arrangements for children, wills, inheritance planning, or legal agreements made during the relationship.
That is one reason cohabitation disputes can become complex quickly. The law does not simply ask what feels fair after a long relationship. It often turns on property law, evidence, and whether ownership, intentions, or contributions can actually be proved.
Property disputes between unmarried couples can be complicated
One of the most common misunderstandings is around the family home. Many people assume that if they lived in a property for years, paid household bills, or contributed to the relationship financially in other ways, they must automatically have a claim over that property.
That is not always the case.
The law relating to property disputes between unmarried couples is complex and often governed by the Trusts of Land and Appointment of Trustees Act 1996. These cases can become highly fact-sensitive, particularly where ownership is in one name but the other partner says there was a shared understanding, contribution, or expectation. That is why specialist legal advice is often essential.
Common situations where people discover the myth too late
The “common law marriage” myth often becomes a problem when:
- A long-term relationship ends and one person realises the home is not in their name
- One partner expected financial support after separation but has no claim as a spouse would
- A surviving partner discovers they do not inherit automatically
- There was no cohabitation agreement, declaration of trust, or clear ownership record
- Children were involved, but the parents were never married
These situations are often difficult because one partner may feel they built a life together in every practical sense, only to find that the law does not treat the relationship as marriage.
How can unmarried couples protect themselves?
Cohabiting couples are not powerless, but they do need to be proactive.
Depending on the situation, sensible steps may include:
- Entering into a cohabitation agreement
- Recording property ownership clearly
- Putting a declaration of trust in place where appropriate
- Making or updating wills
- Reviewing pension nominations and death benefit arrangements
- Taking legal advice before buying property together or moving into one partner’s home
These steps can feel unromantic at the time, but they are usually far easier than trying to resolve uncertainty after a relationship has broken down or after one partner has died.
Is the law likely to change?
Possibly, but people should not rely on future reform to protect them now.
Change to the law has been discussed for some time. The Law Commission has recommended reform in this area, and further change may follow. But reform will not happen overnight, and anyone living with a partner should make decisions based on the law as it stands now rather than assumptions about what may change in future.
When should you get legal advice?
It is worth taking advice if:
- You are moving in together
- You are buying property with a partner
- You are already cohabiting and want to protect your position
- Your relationship has broken down
- There is a dispute over property or financial contributions
- You are worried about what would happen if one partner died
The earlier you understand the legal position, the easier it usually is to avoid false assumptions and put proper protection in place.

Frequently Asked Questions About Common Law Marriage
If you are living with a partner and are unsure what legal protection you do or do not have, these are some of the most common questions people ask about common law marriage and unmarried couples’ rights.
Is common law marriage real in England and Wales?
No. There is no such thing as common law marriage in England and Wales, even if a couple have lived together for many years.
Do I get rights after living together for a certain number of years?
No automatic marital rights arise just because you have lived together for a long time.
Can an unmarried partner claim maintenance after separation?
Not in the same way a spouse may be able to on divorce. The position is very different for unmarried couples.
Do unmarried partners automatically inherit?
No. Cohabiting partners do not have the same automatic inheritance position as spouses.
What if the house is in my partner’s sole name?
You may still need legal advice about whether you have any interest in the property, but there is no automatic right simply because you lived there together.
Can a cohabitation agreement help?
Yes. A cohabitation agreement can help record intentions and provide clarity about finances, property, and expectations.
Do unmarried partners have pension rights if one partner dies?
Not automatically in the same way a spouse may do. The position depends on the type of pension scheme, any nomination made, and the rules that apply, which is one reason wider legal and financial planning matters for cohabiting couples.
Is the law on cohabitation changing?
The Government has said it intends to consult on strengthening protections for cohabiting couples, but the current law remains in force unless and until reform happens.
