The rules use family relationships
Intestacy means dying without a valid will that deals with the assets concerned. It can also apply to part of an estate if a will does not cover everything.
An estate is the money, property and belongings a person leaves. Who inherits under intestacy depends on the relatives who survive them and other facts. A spouse or civil partner does not necessarily receive everything when there are children.
Use the official inheritance checker for the relevant family situation. This page does not calculate anyone’s share.
Some close people may not inherit
In England and Wales, an unmarried partner has no automatic right to inherit under intestacy. The length of the relationship does not change that rule.
Friends and charities are not included. Stepchildren do not inherit as children under these rules unless they were legally adopted. A will can name people and causes you want to benefit.
Some partners, family members or dependants may be able to make a separate claim for financial support. This is not automatic inheritance. Seek prompt legal advice if a claim may be needed, because time limits can apply.
Check assets that pass another way
Not every asset follows the intestacy rules. A home owned as joint tenants normally passes to the surviving owner. Other arrangements, including some pensions and policies, need checking with the provider.
Do not assume that everything in a person’s name is handled in the same way. Find the ownership records and ask for advice if the position is unclear.
If someone has already died
First check whether a valid will exists. Ask close family and any solicitor or storage service the person used.
If there is no will, an eligible person may apply to deal with the estate as its administrator. Being close to the person does not by itself give you that right. Check the official rules before applying or giving out money.

If you are planning for your own family
Write down who you want to inherit and who would handle the work. Then choose a suitable way to make a will. If your family includes an unmarried partner, stepchildren or someone who needs support, consider personal advice.
The rules above concern England and Wales. Scotland and Northern Ireland have their own routes. A cross-border estate may need specialist help.
