Cohabitation has become more common in the UK, with the Office for National Statistics reporting that cohabiting couples are the fastest-growing family type. Despite this trend, many couples remain unaware of their legal position.
Understanding your legal status as a cohabiting couple
Perhaps the most persistent misconception is the notion of ‘common law marriage’—the belief that couples living together for a certain period automatically gain the same legal rights as married couples. This is categorically untrue. In the eyes of UK law, unmarried couples who live together have fewer protections regardless of how long they have shared a home or even if they have children together. This legal distinction can have implications if the relationship ends or if one partner dies, potentially leaving the surviving partner vulnerable.
Establishing property and financial rights
For cohabiting couples, property ownership is often a major legal challenge. If a property is owned solely by one partner, the non-owning partner may have limited rights to remain in the home if the relationship ends, even after many years of cohabitation. When purchasing property together, couples have two main ownership options: joint tenants (where both own the entire property equally) or tenants in common (where each owns a specific share). The latter can be important for cohabiting couples, as it allows for different ownership percentages and provides clarity on what happens to each share upon death. Cohabiting partners have no automatic rights to each other’s pensions, savings, or other assets. They also lack automatic inheritance rights if one partner dies without a will. Creating a cohabitation agreement that outlines how property, assets, and finances would be divided if the relationship ends can give protection for both parties. These agreements, while not automatically legally binding, carry significant weight in court if properly drafted.

Securing parental responsibilities and rights
For unmarried parents, establishing parental responsibility—the legal rights and responsibilities toward a child—needs a few additional steps compared to married couples. While mothers automatically have parental responsibility, unmarried fathers only obtain it by being named on the birth certificate (for children born after December 2003 in England and Wales), signing a parental responsibility agreement, or obtaining a court order. Without parental responsibility, a father cannot make decisions about his child’s education, medical care, or religious upbringing. Consulting with family lawyers can give valuable guidance through the legal processes of establishing parental responsibility and guaranteeing the protection of both parents’ rights regarding their children.
Navigating recent legal developments and reforms
The legal matters for cohabiting couples are changing. The UK government announced plans to consult on potential reforms to cohabitation laws to offer greater protection to unmarried couples. These proposed reforms acknowledge the changing nature of family structures and aim to address the current legal disparities.
Until comprehensive reforms are enacted, however, cohabiting couples must take steps to protect their legal positions through cohabitation agreements, wills, and clear documentation of property ownership. Being informed about your current legal status and taking appropriate protective measures is still essential for all cohabiting couples.
