Cohabitation Rights Bill: Closing the Legal Gap for Unmarried Couples

A fast-growing family type with few rights

Cohabiting couples, those who live together without marrying or entering a civil partnership, are among the fastest-growing family types in the UK. Yet the law offers them far fewer protections than married couples, particularly when a relationship ends or one partner dies. A new bill seeks to address that mismatch.

The gap matters because family structures have changed faster than the law. Many people build lives, homes and families together outside marriage, assuming the law will treat them fairly if things go wrong. Often it does not.

The common law marriage myth

A persistent and damaging misconception is the belief in 'common law marriage', the idea that living together for long enough confers marriage-like rights. In England and Wales, no such status exists. Couples who rely on it can find themselves with no legal claim to property, pensions or support when they separate.

This myth causes real harm because it discourages people from making formal arrangements. By the time they discover the truth, often at the point of separation or bereavement, it is too late to protect themselves.

What the bill would change

The bill would create a framework of legal protections for cohabiting partners, typically covering how property and finances are treated on separation and what happens when a partner dies without a will. The aim is to provide a safety net, particularly for the financially weaker partner, who is often the primary carer of children.

Importantly, such reforms usually stop short of treating cohabitation as identical to marriage. The intention is to prevent injustice, not to abolish the distinction between the two, preserving choice while closing the worst gaps in protection.

Who benefits most

The people most exposed under the current law are often women who have taken on caring responsibilities, reducing their earnings and pension contributions while their partner's career and assets grew. When such relationships end, the law can leave them with little, despite years of contribution.

Children are also affected. Financial insecurity for a parent after separation has direct consequences for the children in their care, which is why the bill is framed not only as a fairness issue for adults but as a matter of family welfare.

The arguments against

Opponents raise several objections. Some argue that couples who choose not to marry are exercising a choice that should be respected, and that extending marriage-like rights undermines that choice. Others worry about legal complexity and the difficulty of defining when cohabitation triggers protections.

Supporters respond that the current situation does not reflect informed choice but widespread misunderstanding, and that a sensible framework can protect the vulnerable without forcing marriage-like obligations on those who genuinely want none.

What couples can do now

While the law remains unchanged, couples who live together can take practical steps to protect themselves. Making a will is essential, because without one an unmarried partner may inherit nothing. Cohabitation agreements can set out how property and finances would be divided, and ensuring both partners are named on relevant documents can prevent disputes later.

Legal advisers routinely stress these measures precisely because the law offers cohabitants so little by default. The gap between what people assume and what the law provides is dangerous, and awareness is the first defence. Whatever happens to the bill, the message for couples is that they cannot rely on an imagined common law marriage and should make deliberate arrangements.

Reform that respects choice

A common misconception about cohabitation reform is that it would force marriage-like obligations on couples who have chosen to avoid them. Most serious proposals are careful to preserve choice, offering protections that can be tailored or opted out of, and distinguishing cohabitation from marriage rather than erasing the difference. The aim is to prevent injustice, not to abolish a valid choice.

This distinction is central to the political case for reform. By framing the changes as a safety net against hardship rather than an imposition, supporters seek to reassure those who value the freedom not to marry. Whether the bill strikes this balance convincingly will shape how much opposition it attracts and whether it can build the consensus needed to become law.

What to watch next

Family law reform of this kind has been recommended by legal experts for years but has repeatedly lacked government time. The bill's progress will show whether that is finally changing. Key details include how cohabitation is defined and what protections are triggered.

For the millions of couples living together, the practical message is unchanged for now: the law offers limited protection, and formal arrangements such as wills and cohabitation agreements remain important. The bill, if it advances, could begin to close a gap that has caused hardship for decades.
