When someone dies without leaving a will, their next of kin stands to inherit most of their estate. Exactly who inherits first, and how much they inherit, is defined by a set of laws in England and Wales called the rules of intestacy.

In order of priority, this is who inherits under the rules of intestacy:

NEXT OF KIN

(A) This term is used to signify the relations of a party who has died intestate. 2. In general no one comes within this term who is not included in the provisions of the statutes of distribution. A wife cannot, in general, claim as next of kin of her husband, nor a husband as next of kin of his wife. But when there are circumstances in a will which induce a belief of an intention to include them under this term, they will be so considered, though in the ordinary sense of the word, they are not.
