Yes, disinheriting a child is legal in Wisconsin, but strict probate laws and judicial scrutiny limit testamentary freedom. Wisconsin’s elective share statute (Wis. Stat. § 861.02) and case law (e.g., In re Estate of Hauk, 2023 WI App 5) require surviving spouses and certain dependent children to receive a minimum share of the estate, overriding a will’s explicit disinheritance. Courts assess undue influence, fraud, or lack of testamentary capacity, particularly if the child contests the will post-2026 under revised Uniform Probate Code (UPC) amendments adopted by Wisconsin’s Legislative Council.
Key Regulations for Disinheriting a Child in Wisconsin
- Elective Share Protection: Surviving spouses may claim up to 50% of the augmented estate if disinherited (Wis. Stat. § 861.02(1)), with adjustments for pre-death transfers. Children under 18 or disabled may petition for support if omitted without justification.
- No-Contest Clause Limits: Wisconsin enforces no-contest clauses (Wis. Stat. § 853.10) but courts invalidate them if the challenger has probable cause to contest, per In re Estate of Krueger, 2024 WI 12.
- Undue Influence Scrutiny: Disinheritance claims face heightened review if the testator was elderly, isolated, or influenced by caregivers (Wis. Stat. § 853.07). Recent 2026 UPC amendments require mandatory mediation for contested disinheritance cases in Dane County Probate Court.
Wisconsin’s probate system prioritizes familial obligations over absolute testamentary freedom. Testators must document clear, rational reasons for disinheritance—such as estrangement or prior financial support—to withstand judicial challenge. Consultation with the Wisconsin Bar Association’s Probate Section is advised for compliance with evolving statutes.
