Estate Planning for Blended Families: Where the Default Rules Fall Apart

Blended families are where estate planning gets emotionally complicated and legally interesting. The Pennsylvania intestacy statute was written for a 1950s family structure: one marriage, shared children, a single household. Real families today rarely match that template.

Without a deliberate plan, a common outcome looks like this: a parent dies, the surviving spouse inherits the bulk of the estate, the surviving spouse later updates their own will, and the children from the first marriage are unintentionally written out. Nobody set out for that — but the default rules made it the path of least resistance.

Tools that help: a QTIP trust (qualified terminable interest property) that provides for a surviving spouse while preserving principal for children from a prior marriage; carefully titled life insurance and retirement accounts with named beneficiaries; and clear, written intent about personal property — the framed photos and grandmother's ring that cause more arguments than the house.

The honest conversation is the hardest part. I encourage couples to have it together, in one room, on a calm afternoon — before any document is drafted. The plan that comes out of that conversation almost always works. The plan drafted around the conversation almost never does.
