Cohabitation Law Reform 2026 – What the Consultation Means for You

If you live with a partner but aren’t married, you may have heard that the law is finally about to change in your favour. It’s true, but not yet, and not automatically. In June 2026 the Ministry of Justice opened a public consultation called “A fairer end to relationships,” looking at both cohabitation rights and how finances are divided on divorce. It’s the most significant review of cohabitation law in almost two decades.

Here’s what the cohabitation law reform 2026 consultation actually proposes, what it doesn’t change yet, and what you can do right now to protect yourself while the law catches up.

What problem is the cohabitation law reform trying to solve?

Cohabitation is one of the fastest-growing living arrangements in England and Wales. ONS figures show the number of people living with a partner outside marriage or civil partnership rose from around 5.5 million in 2014 to 6.5 million in 2024. Roughly one in four people who live as part of a couple are not married or in a civil partnership.

Yet the law hasn’t kept pace. Unmarried couples currently have:

• No automatic right to financial support from each other
• No automatic share in property held in one partner’s name
• No automatic inheritance if a partner dies without a will

This gap is often described as the “common law marriage myth,” the widespread but false belief that living together for long enough creates legal rights similar to marriage. It doesn’t, and it never has.

What’s actually being proposed in the cohabitation consultation

The consultation, which opened on 5 June 2026 and closes on 14 August 2026, is seeking views on a new legal framework that would give cohabiting couples some financial protection when a relationship ends, either through separation or death. Based on the consultation document and the Law Commission’s earlier 2007 recommendations, the areas under discussion include:

• Limited financial claims for long-term cohabiting partners on separation
• Stronger protection for the financially weaker partner, often the one who reduced their working hours or gave up a career to raise children
• Inheritance rights for unmarried partners where no will exists
• The qualifying conditions that would trigger these rights, for example a minimum length of cohabitation, or having a child together

Importantly, the government has been clear that reform is not about treating cohabitation as identical to marriage. Any new framework is expected to be more limited than the rights married couples already have, and current proposals suggest cohabitants should not end up better off than a married couple in the same situation. This is a key point for anyone researching unmarried couples’ rights 2026: the direction of travel is towards limited, targeted protection, not full parity with marriage.

What this doesn’t change yet

This is the part that matters most for anyone reading the news and wondering whether they need to act now: nothing has changed in the law yet. A consultation is the Government asking for views before deciding on a policy. It is not a bill, and it is not in force. Even once the consultation closes and a policy is agreed, new legislation is unlikely to take effect before 2027 at the earliest, and some estimates put full implementation closer to 2028.

Until then, the current rules still apply in full. If you separate from an unmarried partner tomorrow, the courts will apply exactly the same limited framework that exists today, regardless of what’s being discussed in Parliament.

What you can do now, while the law catches up

The gap between “reform is coming” and “reform is law” is exactly why family solicitors are seeing rising demand for cohabitation agreements. A cohabitation agreement is a written contract between partners that sets out how property, finances, and arrangements for children would be handled if the relationship ended, and it’s enforceable under ordinary contract law today, without waiting for any new legislation.

If you’re currently living with a partner, or planning to move in together, it’s worth considering:

• A cohabitation agreement covering property, savings, debts and household contributions
• A declaration of trust if you’re buying a property together, setting out exact ownership shares
• An up-to-date will, since cohabiting partners have no automatic inheritance rights, this is one of the most reliable ways to protect a partner if you die
• Reviewing existing agreements periodically as the reform progresses, so they stay aligned with any new legal framework once it arrives

If you’re married rather than cohabiting, a pre- or post-nuptial agreement serves a similar purpose within marriage, and a will remains essential regardless of your relationship status.

Will reform affect an agreement I sign now?

This is one of the most common questions we’re asked. In general, a properly drafted cohabitation agreement is designed to work alongside the law as it stands, not instead of it, so a new statutory framework would sit on top of a private agreement rather than override it. We’d expect any future legislation to include transitional provisions, but no couple should delay protecting themselves on the assumption that reform will arrive quickly, given the realistic 2027 to 2028 timeline.
