The stepchildren who were accidentally disinherited

Let me tell you about a family — the details changed, and in truth a blend of situations seen many times in practice — where two decent people did what looked sensible, and three children still ended up with nothing.

The setup: a second marriage, simple wills

A second marriage. He brings two children from his first; she brings one from hers. They make simple mirror wills: everything to each other, and then “to my children.” It feels complete, even generous. It is a time bomb.

How the bomb goes off

He dies first. Everything passes to her — exactly as planned, and nothing has gone wrong yet. Years pass. When she dies, her will — or the intestacy rules, if she never updated — benefits her child. Because in law, “my children” means biological or adopted children only. His two are stepchildren to her: not included, not entitled, nothing.

A simpler variation reaches the same place: no wills at all. Intestacy hands most or all to the surviving spouse — and the same funnel ends the same way, with one side of the family inheriting everything and the other inheriting a grievance.

The remarriage twist

It can get worse. If the survivor remarries, the remarriage revokes her existing will — and the new spouse's intestacy entitlement pushes the first family even further from the table. Each step is legally unremarkable; the cumulative effect is a family disinherited by paperwork.

Why the law works this way

Step-relationships simply do not count in succession law unless a will names them. Warmth, school runs, twenty shared Christmases — legally irrelevant. For blended families, the default rules are not merely imperfect; they are pointed in the wrong direction.

What actually protects everyone

The solutions are well established: naming stepchildren expressly, and — where the real worry is protecting the survivor and guaranteeing each side's children — structures such as a life-interest trust, which lets the survivor benefit for life while ring-fencing each family's share underneath. Which structure fits depends entirely on your family's shape — which is exactly the conversation a proper will appointment exists to have.

If yours is a blended family without an up-to-date, deliberately drafted will, you are in the single highest-risk category there is for accidental disinheritance. It is also one of the most fixable.
