How is inheritance split between a surviving spouse and stepchildren under UK intestacy rules?

Full answer

A critical and often surprising feature of intestacy rules (which apply when someone dies without a valid will) in England and Wales is that stepchildren have absolutely no automatic legal right to inherit anything from a stepparent's estate, no matter how long they were raised together or how close the relationship was — intestacy only recognises biological children and legally adopted children as children for inheritance purposes. If someone dies intestate leaving a spouse or civil partner and children (their own biological or adopted children, not stepchildren) the surviving spouse receives: all personal possessions of the deceased, a statutory legacy of the first £322,000 of the estate, and half of anything remaining above that figure; the deceased's own children then inherit the other half of anything above £322,000 in equal shares (held in trust until age 18 if still minors), but any stepchildren of the deceased who are not also that deceased's biological or adopted children receive absolutely nothing under intestacy, regardless of the family relationship during the deceased's lifetime. This gap catches many blended families entirely off guard, particularly where a stepparent has effectively raised stepchildren as their own for many years without ever legally adopting them. The only way to ensure stepchildren inherit anything is for the stepparent to make a valid will explicitly naming them as beneficiaries — without this, a stepchild has no automatic entitlement and would generally need to bring a costly, uncertain claim under the Inheritance (Provision for Family and Dependants) Act 1975 arguing they were treated as a child of the family and reasonable financial provision was not made for them, which is a considerably weaker legal position than being a named beneficiary in a will. For anyone in a blended family relying on a partner or stepparent's estate, checking whether a valid, up-to-date will actually exists — and explicitly includes stepchildren if that is the family's wish — is essential, since intestacy will not achieve that outcome automatically. Use the Inheritance Tax calculator to also check whether any Inheritance Tax would be due on the estate before it is distributed.
