Who Inherits When There Is No Will in Wisconsin
Here is exactly how Wisconsin divides an estate when there is no will:
| If the person leaves… | Who inherits in Wisconsin |
|---|---|
| Spouse, no children | The surviving spouse receives the entire net estate (100%). Under § 852.01(1)(a), if the decedent has no surviving issue, or all surviving issue are also issue of the surviving spouse, the spouse inherits everything. |
| Spouse + shared children | The surviving spouse receives the entire net estate (100%). Under § 852.01(1)(a), when all surviving children/descendants are also children of the surviving spouse, the spouse takes the whole estate. Children inherit nothing until the surviving spouse’s later death. |
| Spouse + children from another relationship | The surviving spouse receives one-half (50%) of the decedent’s property OTHER THAN the decedent’s interest in marital property and property held equally and exclusively with the surviving spouse as tenants in common (spouse already owns those). The remaining one-half passes to ALL of the decedent’s issue (children and descendants of deceased children) by representation. This applies under § 852.01(1)(a) when one or more of the decedent’s surviving issue are NOT issue of the surviving spouse. Note: Wisconsin is a marital property (community property) state, so the surviving spouse already owns 50% of marital property outright — only the decedent’s half of marital property enters the estate. |
| Children, no spouse | The entire net estate passes to the decedent’s issue (children and descendants of deceased children) by representation under § 852.01(1)(b). |
| No spouse, no children | Under § 852.01(1)(c)-(f): First to parents equally, or to the surviving parent. If no parents survive, then to brothers and sisters and the issue of any deceased brother or sister, per stirpes. If no siblings or their issue survive, then one-half to maternal grandparents (equally, or to the survivor, or to their issue per stirpes) and one-half to paternal grandparents (same manner). If one side has no surviving grandparent or issue of a grandparent, the entire estate goes to relatives on the other side. |
| No living relatives (escheat) | Under § 852.01(3), if there are no heirs under any subsection, the net estate escheats to the State of Wisconsin and is added to the capital of the school fund. Escheat occurs only if absolutely no qualifying relatives exist. |
These shares come from Wisconsin intestate-succession law (Wisconsin Statutes § 852.01).
How Wisconsin divides shares among descendants: Wisconsin uses per stirpes (called “by representation”) under § 854.04. Property is divided into equal shares at the first generational level with living members or deceased members who left surviving issue. Each surviving member at that level takes one share; each deceased member’s share passes down to their issue in the same manner.
Wisconsin homestead and family allowance: Under § 861.21, the surviving spouse may petition the court (within 6 months of death) to have the decedent’s entire interest in the family home assigned to the spouse, provided no governing instrument directs otherwise. “Home” includes any dwelling the decedent had an interest in that the surviving spouse occupies or intends to occupy.
Under § 861.33, the surviving spouse may select personal property not used in trade up to 3000 in inventory value. Under § 861.31, the court may order an allowance for the surviving spouse and minor children during estate administration (initial period up to one year, renewable).
Under § 861.35, the court may order a special allowance for support and education of minor children (up to age 18) and support of the surviving spouse after administration.
Half-blood relatives in Wisconsin: Under § 852.03(3) referencing § 854.21(4), half-blood relatives inherit equally with whole-blood relatives. A half-sibling has the same inheritance right as a full sibling.

Assets That Pass Outside Wisconsin Intestate Rules
Beneficiary-designated accounts (life insurance, POD/TOD accounts, retirement accounts with named beneficiaries), property held in joint tenancy with right of survivorship, and assets in a living trust all pass OUTSIDE Wisconsin intestate succession rules and are not governed by Chapter 852. Only the decedent’s probate estate is subject to intestate distribution.
Other Wisconsin intestacy rules: Wisconsin is a marital property (community property) state under the Uniform Marital Property Act — the surviving spouse already owns 50% of all marital property outright before intestate succession applies to the decedent’s half. Registered domestic partners have the same intestate rights as a surviving spouse throughout Chapter 852.
A 120-hour (5-day) survivorship requirement applies under § 854.03 — an heir must outlive the decedent by at least 120 hours (proven by clear and convincing evidence) to inherit, UNLESS applying the rule would cause the estate to escheat.
Children born to unmarried parents inherit from the mother automatically; they inherit from the father only if paternity was adjudicated, admitted in open court, or acknowledged in a signed writing (§ 852.05). Adopted children are treated identically to biological children; stepchildren and foster children do NOT inherit under intestate succession.
What Dying Without a Will in Wisconsin Really Means
When someone dies without a will in Wisconsin, the state’s intestate-succession law — not the family — decides who inherits. The shares above show exactly how Wisconsin divides an estate when someone is dying without a will in Wisconsin, and they often surprise people: a spouse may not automatically inherit everything.
Understanding dying without a will in Wisconsin helps a family know what to expect before they walk into probate court. Remember that some assets pass outside these rules entirely, so the full picture of dying without a will in Wisconsin depends on how each asset was titled.
