Intestacy Rules UK 2026: Who Actually Inherits If You Die Without a Will?

If you die without a valid will in England or Wales, you die intestate. That word matters more than most people realise. It means the state decides who inherits your estate — according to a strict legal formula called the intestacy rules. Your wishes, your relationships, and your family dynamics don't come into it.

What Are the Intestacy Rules?

The intestacy rules are a legal framework set out in the Administration of Estates Act 1925, as amended. They create a priority order for who inherits when there's no will. This order is fixed. A long-term partner, a close friend, or a carer of twenty years gets nothing unless they're in the right category. Meanwhile, a sibling you haven't spoken to in a decade could inherit everything.

The rules apply in England and Wales. Scotland has its own system. Northern Ireland has similar but slightly different rules.

The Intestacy Order: Who Inherits and How Much

If You Are Married or in a Civil Partnership

Your spouse or civil partner is first in line — but not necessarily for everything.

If you have no children: Your spouse or civil partner inherits your entire estate.

If you have children: Your spouse or civil partner receives:

• All your personal possessions (furniture, jewellery, cars, etc.)
• The first £322,000 of your estate (the “statutory legacy”)
• Half of anything above £322,000

Your children share the other half of anything above £322,000, equally between them. So if your estate is worth £500,000, your spouse gets £322,000 plus half of £178,000 (£89,000) = £411,000 total. Your children share the remaining £89,000.

If You Are Not Married or in a Civil Partnership

This is where the rules get particularly harsh for modern families. If you are single, divorced, or separated (but not legally divorced), the following order applies:

1. Children — they inherit everything equally. If a child has died before you, their children (your grandchildren) inherit their share.
2. Parents — if you have no surviving children or grandchildren
3. Full siblings — if both parents are dead
4. Half siblings — if there are no full siblings
5. Grandparents — if none of the above
6. Aunts and uncles (full blood) — then their children if deceased
7. Half aunts and uncles — then their children if deceased
8. The Crown (bona vacantia) — if no blood relatives can be found

The Cohabiting Couples Myth

This is the most important thing to understand about intestacy in the UK in 2026.

Cohabiting couples — people who live together but are not married or in a civil partnership — have no automatic right to inherit from each other.

None. Zero. Not a penny. There is no such thing as a “common law spouse” in English law. Regardless of how long you have lived together, whether you share a home, have children together, or refer to each other as husband and wife — if you are not legally married or in a civil partnership, you are strangers to each other's estates under intestacy law.

This affects an estimated 3.6 million cohabiting couples in the UK. If one partner dies without a will, the surviving partner may lose their home, their savings, and everything they built together — while the deceased's parents or siblings inherit instead.

The only way to protect a cohabiting partner is to write a will. See WillSafe's cohabiting couples inheritance guide for full details.

What About Children Born Outside Marriage?

Children born to unmarried parents have the same inheritance rights as children born within marriage, provided the relationship is legally established. For children born after 1 December 2003, if their father is named on the birth certificate, they are recognised as legitimate heirs.

Adopted children are treated the same as biological children. Stepchildren who are not legally adopted have no automatic rights under intestacy.

What the Intestacy Rules Can't Do

Even with the best intentions, the intestacy rules cannot:

• Appoint a guardian for your minor children (no will = no guardian named)
• Leave a gift to a charity
• Give anything to a friend, a carer, or a step-child who hasn't been adopted
• Protect a cohabiting partner
• Reduce inheritance tax through planning
• Set up a trust for a child with a disability or under 18

A will does all of these things. The intestacy rules do none of them.

Can You Challenge the Intestacy Rules?

Yes, in limited circumstances. Under the Inheritance (Provision for Family and Dependants) Act 1975, certain people can make a claim against an intestate estate. This includes a spouse or civil partner, a cohabiting partner who lived with the deceased for at least two years immediately before death, a child, and anyone who was being maintained by the deceased.

However, these are court claims. They are expensive, slow, emotionally distressing, and uncertain in outcome. They are not a substitute for a valid will.
