Updated September 5, 2026. Quick answer: Wisconsin’s elective share is not the one-third-of-everything, marriage-length figure most national pages describe. no more than 50% of the ‘augmented deferred marital property estate’; protects the spouse’s interest in property that would have been marital property under Wisconsin’s marital-property system but wasn’t (e.g. property acquired before the marital property act or brought in from another state); flat, not tied to marriage length
What Wisconsin actually sets out
| What the statute sets out | What it says |
|---|---|
| Wis. Stat. Sec. 861.02 (amount) | “an amount equal to no more than 50 percent of the augmented deferred marital property estate as determined under sub. (2).” |
| The share and what it is measured against | no more than 50% of the ‘augmented deferred marital property estate’; protects the spouse’s interest in property that would have been marital property under Wisconsin’s marital-property system but wasn’t (e.g. property acquired before the marital property act or brought in from another state); flat, not tied to marriage length; measured against the decedent’s and surviving spouse’s deferred marital property, including certain probate/nonprobate transfers and gifts made within 2 years of death. |
| Regime type | a share of deferred marital property only |
| Can it be waived | waivable wholly or in part, before or after marriage, via a marital property agreement, or by a signed document filed with the court after the decedent’s death |
| Time limit to file | petition must be filed with the court within 6 months after the date of the decedent’s death |
How it works in practice
- The share is measured against the decedent’s and surviving spouse’s deferred marital property, including certain probate/nonprobate transfers and gifts made within 2 years of death.
- No. This state’s formula is deliberately built to reach revocable trusts, payable-on-death accounts and other lifetime transfers, precisely so the elective share cannot be defeated by moving assets out of probate before death.
- Waiver: Waivable wholly or in part, before or after marriage, via a marital property agreement, or by a signed document filed with the court after the decedent’s death.
- The election has to be affirmatively filed on a deadline: petition must be filed with the court within 6 months after the date of the decedent’s death.
The national picture, including the Uniform Probate Code sliding-scale schedule that a minority of states actually use, is on the elective share calculator page; this page is the record for Wisconsin specifically, and its own numbers above should be used instead of the calculator’s national default for a Wisconsin estate. The one thing that reliably defeats an elective share in every state that has one is explained on whether a prenup can waive the elective share. A newly widowed reader working through the fuller list of irreversible decisions, of which this is one, can start from the surviving spouse checklist.
What this page does not settle
- This citation and figure were fetched directly from the state’s own official code site and read against the current text this session.
- A state can amend or repeal this section without the page around it changing, and a detail specific to a reader’s own situation, such as a pending divorce, a premarital agreement, or property held jointly with right of survivorship, can change which part of the statute actually applies.
- Whether a revocable trust changes the outcome in Wisconsin is explained above; that answer is specific to this state and does not generalize to any other one.

Whether this statute reaches a given family’s actual facts is decided by a court, not by this page. Nothing here is legal advice, and no one should sign a waiver or forgo an election on the strength of a web page.
