A stepchild who is raised from kindergarten to college inherits nothing under Wisconsin’s inheritance law. Not a reduced share, not even a last resort share after every other relative has been eliminated. The state school fund takes precedence over that child, and most blended families are unaware of this.
Wisconsin Lists Its Heirs, and Stepchildren Are Not on the List
Under Wis. Stat. Section 852.01, property not disposed of by will is passed in a fixed order. First, to the surviving spouse or domestic partner. Then, to the decedent’s issue. Then to parents. Then brothers and sisters, and their descendants. Finally, grandparents and their issues.
“Issue” means lineal descendants. Biological children are counted. Legally adopted children are also counted. A stepchild is not counted, no matter who paid for the braces or whose name the child uses at graduation.
If no one in the chain survives, the estate does not go to a stepchild as backup. It goes to the state and is added to the school capital fund.
Adoption Is the One Step That Changes the Answer
Wis. Stat. Section 854.20 treats a legally adopted child as a biological child of the adopting parent for all purposes related to intestate succession and transfers at death. Wisconsin also allows the adoption of adults, which is why some families do this decades later than one would expect.
One thing to know is that if a child’s other parent has died, and the surviving parent adopts a new spouse, the child retains the right to inheritance through the deceased parent. Adoption when the other parent is alive works differently because it ends the legal parent-child relationship, which is a family decision made long before it becomes a legal one.
Blended Families Lose the Most Under the Default Rules
Wisconsin treats a second marriage with children from a previous marriage differently than the first marriage. If at least one of the deceased spouse’s children is not also the child of the surviving partner, three things happen simultaneously:
- The surviving spouse receives half of the deceased person’s personal property, which is property that is not considered marital property.
- The deceased’s share of marital property goes to their own children, rather than their spouse.
- Stepchildren, who may be living in the same house as the surviving partner’s children, receive nothing.
Read that second point twice. The surviving spouse keeps their own half of the marital property, and then watches as the other half goes to a group of adult children, who may have very different plans for the family home. The Wisconsin marital property system does a great deal of quiet work in this sentence.
A Will Protects a Stepchild Further Than People Assume
Name the stepchild in a will or trust and the problem disappears. Wisconsin then takes it a step further. Wis. Stat. Section 854.06 defines “stepchild” by name and protects gifts made to them, so if you named a stepchild who dies before you, that gift goes to their children instead of reverting back to your estate. Wisconsin law recognizes this relationship. It just needs you to put it in writing first.
Beneficiary designations deserve the same attention as the will itself. Retirement accounts, life insurance, and pay-on-death accounts are passed by contract, completely outside the will. A designation completed during the first marriage, never revisited, can quietly undo everything else you have planned.
