Cohabitation Law Reform: Protecting Vulnerable Couples in the... 2026

Cohabitation law reform is a pressing issue for 3.5 million unmarried couples in the UK who currently lack legal protection when relationships end or a partner dies. The proposed reforms, championed by David Lammy, aim to modernise family law while respecting individual choice.

The Case for Cohabitation Law Reform

Opponents like Ruth Deech argue that choosing not to marry should mean no automatic legal rights. However, the current system leaves many vulnerable partners—especially women and children—without financial safety nets. Many couples still mistakenly believe in the myth of common law marriage, assuming they have rights they do not.

The proposals strike a balance between autonomy and protection. Couples can opt out of the legal framework if they wish, preserving choice while safeguarding those who need it most.
