Wisconsin Marital Property Law in Estate Disputes: When a Will Contradicts Surviving Spouse Rights
In Wisconsin, a deceased spouse cannot completely disinherit a surviving spouse by willing all property to someone else. Under the state's marital property laws, surviving spouses have explicit rights to a deferred elective share and an automatic one-half interest in community assets, regardless of what the will says.
Understanding Wisconsin Marital Property Law in Probate
Wisconsin is one of the few states in the U.S. that operates under a community property system, officially known as Marital Property under state law. According to Wis. Stat. § 766.31, any property acquired by either spouse during the marriage is generally presumed to be marital property. Each spouse holds an undivided, one-half interest in these assets. When a spouse passes away, estate disputes frequently erupt if the deceased spouse's will attempts to leave 100% of the estate to children from a previous marriage, a charity, or a third party. A will can only control the deceased spouse's half of the marital property and their individual, pre-marital assets. The surviving spouse retains their own half.

Disputing the Classification of Survivorship Marital Property
How an asset is titled can completely bypass a will. In Wisconsin, spouses can hold property as 'survivorship marital property.' When one spouse dies, this specific type of property automatically transfers to the surviving spouse outside of the probate process. Disputes often arise when a deceased spouse tries to bequeath a home or a bank account to a different beneficiary through their will, unaware that the survivorship title takes legal precedence.
Litigation frequently happens at the Milwaukee County Circuit Court, Milwaukee or the Dane County Circuit Court, Madison when stepchildren attempt to force the surviving spouse to share or sell a survivorship asset. The surviving spouse must firmly assert their rights, proving that the asset's title overrides any contradictory instructions written in the will.
The Surviving Spouse's Elective Share Rights Under Chapter 861
Even if a deceased spouse intentionally tries to disinherit their surviving spouse using individual property, Wisconsin law provides a powerful safety net. Under Wis. Stat. § 861.02, a surviving spouse has the right to claim an 'elective share' of the deferred marital property. Deferred marital property refers to assets that would have been considered marital property if Wisconsin's Marital Property Act had been in effect when the property was acquired. A surviving spouse can formally elect to take up to one-half of the augmented deferred marital property estate by filing a petition for election with the court pursuant to Wis. Stat. § 861.08(1)(a).
Tracing Commingled Assets
One of the most complex areas of estate litigation involves 'commingled' assets. This happens when a deceased spouse mixed their individual, pre-marital money (which they can freely give away in their will) with marital funds (which the surviving spouse has a 50% right to). If marital and non-marital funds are mixed in a single investment account, the entire account is often presumed to be marital property unless the estate can prove otherwise. Tracing these funds requires intensive forensic accounting. The burden of proof to trace and separate the funds lies heavily on the party claiming the property is individual, a standard reinforced by prominent cases like In re Estate of Kobylski, 178 Wis. 2d 158 (WI Court of Appeals 1993).
Disputes Involving Second Marriages with Children
Estate litigation is most common in second or third marriages where the deceased spouse had children from a prior relationship. The deceased often creates a will attempting to ensure their biological children receive their inheritance, sometimes violating the marital property rights of their current spouse. These disputes are highly emotional. The biological children might accuse the surviving spouse of taking assets that 'belong to the family,' while the surviving spouse is simply enforcing their legal rights to half of the marital estate. An attorney can help mediate this dispute or litigate aggressively to ensure the court properly categorizes the marital versus individual property.
| Asset Type | Legal Presumption in Wisconsin | Can the Deceased Will it Away? |
| Marital Property | Owned 50/50 by both spouses | Only the deceased's 50% share |
| Individual Property | Owned 100% by the individual | Yes, subject to elective share claims |
| Survivorship Property | Passes immediately to survivor | No, title overrides the will |
Frequently Asked Questions (FAQ)
What is a deferred marital property elective share?
It is a legal right that allows a surviving spouse to claim a portion of assets that the deceased spouse owned individually, but which would have been considered marital property if acquired after Wisconsin enacted its marital property laws.
Can a prenuptial agreement override my spousal rights?
Generally, yes. A valid, freely signed marital property agreement (prenup or postnup) can reclassify property and waive elective share rights, provided full financial disclosure was made before signing.
Is a house bought before marriage considered marital property?
Usually, property brought into the marriage is individual property. However, if marital funds were used to pay the mortgage or make significant improvements, the marital estate may have a reimbursable interest in the house.
How long do I have to claim my elective share?
In Wisconsin, under Wis. Stat. § 861.08(1), a surviving spouse must file a petition for the election within six months after the date of the decedent's death. Missing this strict statutory deadline permanently bars the election unless the court grants an extension upon timely petition.
