Cohabitation Law Reform: Protecting Unmarried Couples' Rights 2026

Cohabitation law reform is a critical issue for the 3.5 million unmarried couples in the UK who lack automatic legal rights when a relationship ends or a partner dies. Ruth Deech’s recent article opposing reform overlooks the real hardships faced by financially weaker partners, particularly women and children, who mistakenly believe in “common law marriage” myths.

Why Cohabitation Law Reform Matters

The current system leaves too many vulnerable people without protection. Many couples raise children, share finances, and build lives together without marrying—often for personal, cultural, or financial reasons. When a relationship ends, the financially weaker party can face severe hardship, including loss of home and insufficient support for children.

Domestic Abuse Survivors Need Legal Safety Nets

Reform is essential for victims of domestic abuse. Many remain trapped in abusive relationships because they cannot afford to leave without any legal or financial safety net. A clear legal framework would provide greater certainty and fairness while remaining straightforward for couples to navigate.

How the Proposed Law Strikes a Balance

The proposals respect individual autonomy by allowing couples to opt out of the legal framework. This flexibility ensures that those who consciously choose not to marry aren’t forced into undesired obligations, while protecting those who need it most.

Australia and New Zealand have introduced sensible protections without undermining marriage or causing the catastrophic consequences opponents predict. The UK can learn from these examples.

Key Takeaways from the Reform Proposal

• Many still believe in the myth of “common law marriage”
