According to the latest UK Wills & Probate Consumer Research Report (2025), only 41% of UK adults have made a will, leaving millions potentially subject to intestacy rules if they die.

Graysons says this is particularly concerning given the growing number of cohabiting couples.

It is warning that many people remain unclear about what would happen to their estate if they died without a will, with many still believing in the long-standing myth of “common law marriage” – which has no legal status.

When someone dies without making a will, they are said to have died “intestate”. In these circumstances, strict legal rules determine how their money, property and possessions are distributed.

One of the most common misunderstandings is the belief that unmarried partners automatically inherit. In reality, if a couple are not married or in a civil partnership, the surviving partner does not automatically receive anything from the estate, even if they have lived together for many years.

Laura Cowan, head of the private client team at Graysons, said:

“It often comes as a surprise to people that their partner could receive nothing if they die without a will. Making a will ensures that your wishes are clearly set out and that the people you care about are properly provided for. With more couples choosing to live together without marrying, it is more important than ever that people understand how the law works and take steps to protect their families.”
