Do stepchildren inherit under intestacy?
When someone dies without a valid will, the intestacy rules distribute the estate in a strict order: spouse or civil partner first, then children, parents, siblings, and on down a fixed list of blood relatives. Stepchildren appear nowhere on that list. Unless you legally adopted them, the law treats them as strangers to your estate — regardless of how long you lived as a family or who raised whom.
How do you provide for stepchildren in a will?
A will fixes this completely. You can:
- Leave a specific gift — a fixed sum of money or a particular item, named against each stepchild.
- Give them a share of the residue — for example, splitting everything equally between your children and stepchildren by name.
- Name substitutes, so a stepchild's share passes to their own children if they die before you.
One wording trap: in law, "my children" does not include stepchildren. If you want them included, name them individually. Our guide to writing a will with children covers blended families in more detail.
What happens if an unmarried partner dies without naming stepchildren?
Stepchildren are not the only ones the rules overlook — unmarried partners inherit nothing either, however long the relationship. Couples who live together with children from previous relationships are doubly exposed: the surviving partner gets nothing automatically, and neither do their children. If that is your household, read wills for unmarried couples next — and then make the wills.
How quickly can you fix this with a will?
Including stepchildren costs nothing extra and requires no adoption, no court, and for most families no solicitor — just a will that names them. You can make your will in about 15 minutes with SwiftWill, with free updates for life as the family changes. One honest caveat: stepchildren you financially supported can sometimes claim against an estate that leaves them with nothing — if you plan to exclude a dependant, take advice from a solicitor first.
