Who is next of kin in the UK?
“Next of kin” has no strict legal definition in England and Wales — it's often used loosely for your closest relative. What does carry legal weight is the intestacy order that decides who inherits when there's no will: a spouse or civil partner first, then children, then parents, siblings and more distant relatives. Unmarried partners are not next of kin for inheritance.
Detailed explanation
The everyday term and the legal reality don't always match — which catches people out.
- For medical/emergency purposes, “next of kin” is just a contact — no automatic legal powers.
- For inheritance without a will, the statutory order applies: spouse/civil partner, then children, then other blood relatives.
- Unmarried partners and unadopted stepchildren are excluded from intestacy.
- A will replaces all of this with your own choices.
After Sam dies without a will, his partner of 12 years assumes she's his next of kin and will inherit. Under intestacy she inherits nothing — his estate passes to his children. A will naming her would have changed everything.
