Wisconsin Community Property Laws
Wisconsin is a community property state that does not use the words. In 1986 it enacted the Uniform Marital Property Act, and s. 766.001(2) states the legislature’s intent that marital property is a form of community property. The vocabulary changed, and so did the starting gun: the system begins for a couple not at the wedding but on a statutory determination date, and every classification and creditor question in ch. 766 hangs off it. This page follows that order — the date first, then which property a creditor may actually reach, then the one-signature documents that move the line, then what a surviving spouse may elect. General legal information, not legal advice.
The Short Version
Wisconsin calls it marital property, but s. 766.001(2) says plainly that the legislature intended marital property to be a form of community property. Under s. 766.31(1) all property of spouses is marital property except what ch. 766 classifies otherwise, s. 766.31(2) presumes it, and s. 766.31(3) gives each spouse a present undivided one-half interest in each item of it — not in the pot as a whole.
The unusual part is when that begins. Section 766.01(5) fixes a determination date at the last to occur of the marriage, the moment both spouses are domiciled in Wisconsin, and 12:01 a.m. on 1 January 1986. Property owned at that date is not classified by the chapter at all (s. 766.31(6)(b)) and is treated as individual property during the marriage (s. 766.31(9)). Section 766.55 then decides which pot answers for which debt, and it is not the blanket rule most summaries describe. All of it turns on dated paper: a register of deeds instrument, a notarised statement, a filed entity record. Reading that paper is what we do, once there is a purpose the law permits.
Watch: Wisconsin Marital Property
Why the date, not the wedding, starts the clock.
Watch Overview
The Date That Starts the Whole System
Section 766.01(5), and what it leaves outside.
Every other state in this group begins its community regime at the wedding. Wisconsin begins it on a determination date, which s. 766.01(5) defines as the last to occur of three events: the marriage; 12:01 a.m. on the date that both spouses are domiciled in this state; and 12:01 a.m. on 1 January 1986. The third limb is there because the Marital Property Act was created by 1983 Wis. Act 186 and took effect at the start of 1986, and the second is there because the whole scheme is built on Wisconsin domicile. Section 766.01(8) completes the picture by defining "during marriage" as a period in which both spouses are domiciled here, beginning at the determination date and ending at dissolution or at the death of a spouse.
Work through what that means for two real couples. A couple who married in Green Bay in 1974 have a determination date of 1 January 1986: twelve years of accumulation sit outside the chapter. A couple who married in Minnesota in 2001 and moved to Eau Claire in 2019 have a determination date in 2019, and eighteen years sit outside it. In both cases the answer to "is this marital property?" begins with a date that has nothing to do with the wedding.
What the chapter refuses to classify
Section 766.31(6)(b) is explicit: where the date of marriage precedes the determination date, property owned at the determination date is not classified by this chapter. Subsections (8) and (9) then govern it instead. Subsection (8) preserves the classification and ownership rights of property acquired before the determination date, and of property acquired afterwards in exchange for it or with its proceeds. Subsection (9) provides that during marriage a spouse’s interest in property owned immediately before the determination date is treated as if it were individual property.
So Wisconsin has three categories where the other eight states have two: marital property, individual property, and a body of older property that the Act deliberately declined to touch. That third category is the reason s. 861.02 exists, and it is the reason a Wisconsin file has to establish when a couple actually became domiciled here — a question answered by address history, recorded instruments and filed documents rather than by anybody’s recollection.
Income, appreciation and mixing
Section 766.31(4) makes income earned or accrued by a spouse, or attributable to the property of a spouse, during marriage and after the determination date marital property. That includes income thrown off by individual property, which is the opposite of the Washington rule and matches Idaho’s. Section 766.31(7)(c) keeps appreciation of individual property individual, except to the extent s. 766.63 makes it marital — and s. 766.63(2) does exactly that where one spouse applies substantial labour, skill or managerial activity to the other’s non-marital property, receives no reasonable compensation for it, and substantial appreciation results. Section 766.63(1) adds the tracing rule: mixing marital property with anything else reclassifies the other property as marital unless the non-marital component can be traced.
Which Property Answers for Which Debt
Section 766.55, and the sentence that is usually left out.
The single most repeated claim about Wisconsin is that because it is a community property state, debts run up by one spouse during the marriage are the responsibility of both. Section 766.55 does not say that, and the difference is the whole subject.
Subsection (2)(b) is the broad rule: an obligation incurred by a spouse in the interest of the marriage or the family may be satisfied from all marital property and all other property of the incurring spouse. That reaches the non-incurring spouse’s half of the marital estate. But subsection (2)(d) governs everything else, and it reads the other way: any other obligation incurred by a spouse during marriage may be satisfied only from that spouse’s non-marital property and from that spouse’s interest in marital property, in that order. The other half is not on the list, and the order is a sequence a creditor has to respect rather than a menu.
Subsection (2)(c)1. handles premarital obligations with a phrase worth reading twice. Such a debt may be satisfied only from the obligated spouse’s non-marital property and from "that part of marital property which would have been the property of that spouse but for the marriage" — in practice, that spouse’s own earnings and what they bought. Subdivision 2. applies the identical formula to obligations attributable to anything arising before 1 January 1986, substituting "but for the enactment of this chapter". A creditor tracing a pre-1986 or premarital claim is therefore tracing one spouse’s contribution, item by item.
The signature that closes the question
Section 766.55(1) presumes that an obligation incurred during marriage was incurred in the interest of the marriage or the family. It then permits something rare: a statement separately signed by the incurring spouse, at or before the time the obligation is incurred, stating that the obligation is or will be incurred in that interest, is conclusive evidence that it was. The subsection preserves interspousal rights and remedies, but as between the creditor and the marital estate the classification is settled by a piece of paper signed at closing. Anyone testing exposure on a Wisconsin obligation should be looking for that statement in the loan file before arguing about purpose.
After a decree, and outside Wisconsin
Section 766.55(2m) changes the arithmetic once a dissolution decree is entered: unless the decree says otherwise, no income of the non-incurring spouse is available afterwards to satisfy an obligation under (2)(b), and marital property assigned to each spouse is available only to the extent of its value at the date of the decree. Subsection (7) runs in the opposite direction — property available under the chapter to satisfy an obligation is available regardless of whether it is located in this state, and regardless of whether the chapter has stopped applying because one or both spouses moved away. A Wisconsin obligation does not become unreachable by crossing a state line, which is why an out-of-state recorder index is often part of a Wisconsin file. Where a judgment already exists, the exemptions that survive it are set out on our page covering Wisconsin asset exemptions from creditors, and the mechanics of enforcing one are on Wisconsin judgment collection.
The Section 766.55 Ladder
Each row is a different pot, and the differences are the point.
| The obligation | What it may be satisfied from | Authority |
|---|---|---|
| A duty of support owed to a spouse or a child of the marriage | All marital property and all other property of the obligated spouse. | s. 766.55(2)(a) |
| An obligation incurred in the interest of the marriage or the family | All marital property and all other property of the incurring spouse. Broadest | s. 766.55(2)(b) |
| A premarital obligation, or one arising before 1 January 1986 | That spouse’s non-marital property, plus the part of marital property that would have been that spouse’s but for the marriage or the enactment. | s. 766.55(2)(c) |
| A tort committed by a spouse during the marriage | That spouse’s non-marital property and that spouse’s interest in marital property. | s. 766.55(2)(cm) |
| Any other obligation incurred during the marriage | That spouse’s non-marital property, then that spouse’s interest in marital property — in that order. | s. 766.55(2)(d) |
| An obligation covered by a marital property agreement the creditor never saw | Unaffected by the agreement; only actual knowledge when the obligation was incurred changes a creditor’s position. | s. 766.55(4m) |
Every row turns on a fact rather than a doctrine: when the obligation was incurred, what it was for, whose signature is on it, and whether a separate statement under s. 766.55(1) was signed at the time. Those are records questions before they are legal ones. We assemble the documents; a Wisconsin attorney argues the row.
The Documents That Move the Classification Line
Sections 766.58, 766.587, 766.59, 766.53 and 766.51.
Chapter 766 is unusually generous about letting spouses rearrange the default, and unusually specific about the form each rearrangement takes. That specificity is useful, because a required form is a document that can be found.
A marital property agreement under s. 766.58 must be signed by both spouses, may have only spouses as parties, and is enforceable without consideration. Subsection (3) lets it cover rights in property wherever acquired or located, management and control, disposition on dissolution or death, and even a nontestamentary transfer that passes property without probate at the second death. Subsection (11) is the one that matters to a searcher: married persons, and persons intending to marry, may record a marital property agreement in the county register of deeds office. Subsection (13)(b) then puts a clock on challenges after a death — six months after the inventory is filed under s. 858.01, or eight months after the death where no estate administration is opened at all.
The one-year window nobody remembers
Section 766.587 is a fossil that still has consequences. It set out a statutory individual property classification agreement, on a form printed in the statute in capital letters, which let a couple classify all their property as the individual property of the owner and have ownership determined as if it were 31 December 1985. It could be executed from 1 January 1986 and it terminated on 1 January 1987 by its own terms, with the classification of property acquired before termination surviving. Subsection (6) preserves the surviving spouse’s election under s. 861.02 regardless, and treats property that would have been marital but for the agreement as deferred marital property. A Wisconsin estate that looks strangely lopsided for 1986 may have one of these in a drawer.
A statement one spouse can sign alone
Section 766.59 lets a spouse act unilaterally on one narrow point. That spouse may execute a written statement, signed and acknowledged by a notary, classifying the income attributable to all or some of that spouse’s non-marital property as individual property. It takes effect when executed, or later if it says so; the executing spouse must notify the other within five days by personal delivery or certified mail, and s. 766.59(2)(b) makes failure to do so a breach of the good-faith duty in s. 766.15. It may be recorded with the register of deeds, it may be revoked in writing on the same notice terms, and subsection (5) treats both the statement and the revocation as a marital property agreement so far as third parties are concerned.
Gifts, and the cap in the statute
Section 766.53 caps what one spouse may give away alone: a spouse acting alone may give marital property to a third person only if the aggregate value given to that person in a calendar year does not exceed one thousand dollars, or a larger amount that was reasonable when made, considering the economic position of the spouses. Anything beyond that is subject to the remedies in s. 766.70(6) unless both spouses acted together, and the section requires a gift in which the donor retained an interest to be valued at the full value of the transfer. Section 766.70(6) then attaches one-year clocks running from notice of the gift, from a dissolution, or from a death. Patterns of quiet transfers are the subject of our guide to finding hidden assets in a divorce; this page is about the provisions that make finding them worth the effort.
At a Death: Survivorship and the Elective Share
Sections 766.60 and 861.02.
Section 766.60 lets spouses hold marital property in named forms, and one of them changes what happens at a death. If the words "survivorship marital property" are used, s. 766.60(5)(a) provides that on the death of a spouse the ownership rights of that spouse vest solely in the survivor by nontestamentary disposition, and that the first deceased spouse may not dispose at death of any interest in it. The same subsection warns that holding property simply "as marital property" does not by itself create survivorship.
Subsection (5)(c) is the provision a judgment creditor needs to read. A judgment lien on one spouse’s interest in survivorship marital property does not defeat the right of survivorship. If execution on the lien issued before the death, the survivor takes the deceased spouse’s interest subject to it. If execution did not issue before the death, the survivor takes that interest free of the judgment lien — unless the lien was on both spouses’ interests and all of the spouses’ property was available under s. 766.55 to satisfy the underlying obligation anyway. Whether execution issued, and on what date, is a court-record fact with a very large consequence attached to it. Subsection (5)(b) treats mortgages, ch. 409 security interests and statutory liens differently: the survivor takes subject to those.
The share that answers for the pre-1986 years
The determination date leaves a gap, and s. 861.02 fills it. A surviving spouse may elect an amount equal to no more than fifty percent of the augmented deferred marital property estate. Section 861.02(2)(a) does the heavy lifting: where the marital-property presumption in s. 766.31(2) is rebutted as to an asset, that asset is presumed to be deferred marital property. Subsection (2)(b) then defines the augmented estate to include property irrespective of where it was acquired, where it sat at the time of a relevant transfer, or where it is now — expressly including real property located in another jurisdiction — and pulls in probate and non-probate transfers, the decedent’s gifts of deferred marital property made in the two years before death, and the survivor’s own deferred marital property.
That is an unusually long reach for a survivor’s claim, and it is the reason a Wisconsin estate cannot be inventoried inside Wisconsin alone. A two-year look-back at gifts and an express instruction to count out-of-state real property together describe a records project: out-of-county and out-of-state recorder indexes, entity filings, and the dates on each. Whether an election is available, and what it is worth, is for a Wisconsin attorney and the probate court.
Where a Wisconsin Estate Stops Matching the Paper
Six recurring gaps between what is claimed and what is filed.
An Unrecorded Marital Property Agreement
Section 766.58(11) permits recording but does not require it, so an agreement can be real between the spouses and invisible to everyone else.
A Section 766.55(1) Statement
A separately signed statement at closing is conclusive evidence that an obligation was in the interest of the marriage or the family — and it usually lives in a lender’s file, not a court file.
A Determination Date Nobody Fixed
Section 766.01(5) turns on when both spouses became domiciled here; without that date, nothing after it can be classified.
A Unilateral Income Statement
A notarised statement under s. 766.59 can be executed by one spouse and may or may not have been recorded, yet it redirects income.
A Judgment Lien With No Execution
Under s. 766.60(5)(c) the date execution issued decides whether a survivor takes survivorship property free of the lien or subject to it.
Property Held Outside Wisconsin
Sections 766.55(7) and 861.02(2)(b) both reach across state lines, so an in-state search alone understates the estate.
None of these requires bad faith and we allege none. Most require only that nobody compared a register of deeds index, a DFI entity record and a court file against what was claimed. Making that comparison, and dating it, is the whole job.
How a Wisconsin File Gets Built
Purpose, then the date, then the offices, then the hand-off.
Ask Why Before Asking Where
Nothing gets searched until there is a purpose FCRA, GLBA and DPPA allow, stated and written down. If the request reads as someone trying to find a person who left, we stop there. Wisconsin runs a Safe at Home programme under Wis. Stat. 165.68, administered by the department of justice, which assigns a substitute address to victims of abuse, stalking and trafficking. We are not a way around it and we will say so.
Fix the Determination Date
Marriage date, the date both spouses became domiciled in Wisconsin and 1 January 1986 are compared, because s. 766.01(5) takes the last of them and everything downstream depends on which one wins. Address history and recorded instruments settle it, not recollection.
Work the Offices That Hold the Answer
County register of deeds indexes for deeds, mortgages, satisfactions, liens and any recorded marital property agreement or s. 766.59 statement; Department of Financial Institutions entity and agent filings; UCC records; circuit court judgment and execution entries; titled property; address history.
Hand It Over Dated
Each item comes back with the office, the document number, the recording or filing date and a plain note on confidence — in a shape a Wisconsin attorney can put straight into an inventory, a claim or discovery.

The constraint does not change with the role. Section 766.55 can only be argued from a dated obligation, and s. 861.02 can only be measured against an inventory that reaches out of state. We build that documentary layer and stop there — no classification, no valuation, no opinion on Wisconsin law. Where a person has to be found before any of it can move, that is skip tracing, and it begins with a stated lawful purpose; the Wisconsin-specific version is on our page for finding someone in Wisconsin.
What a Wisconsin File Contains, and What It Never Contains
Chapter 766 runs on dates and on documents: the determination date fixed by s. 766.01(5), the date an obligation was incurred under s. 766.55, the date a marital property agreement was put on record with a register of deeds under s. 766.58(11). Those are the things we read. A Wisconsin file comes back as register-of-deeds instruments, Department of Financial Institutions entity and agent filings, UCC records, titled property and address history — each item with the office it came from, the date it was filed, and a frank note on how far we actually got. We establish a lawful purpose, one FCRA, GLBA and DPPA permit, before we run the search. We use no pretext and we never tell anyone we are somebody else in order to be handed a record, and we do not open accounts or read their contents. Nobody here practises law and nobody here holds a private investigator’s licence. Nor is this a credit bureau; nothing we send is anyone’s consumer report, and it must not decide a Wisconsin job, apartment, loan or policy. Whether a given item is marital or individual property under s. 766.31 is a Wisconsin lawyer’s call, never ours. Records work since 2004.
Wisconsin Marital Property Questions
Answered from ch. 766 and s. 861.02 as read at source.
Is Wisconsin a community property state?
Yes, and the statute says so in terms. Wis. Stat. s. 766.001(2) records that "it is the intent of the legislature that marital property is a form of community property." Wisconsin adopted the Uniform Marital Property Act effective 1 January 1986, which is why the vocabulary is different from the other eight states: what they call community property Wisconsin calls marital property, and what they call separate property Wisconsin calls individual property. Under s. 766.31(1) all property of spouses is marital property except what the chapter classifies otherwise, and s. 766.31(2) presumes it. General legal information, not legal advice.
When did the marital property system start for a particular couple?
On that couple’s determination date, which s. 766.01(5) defines as the last to occur of three things: the marriage; 12:01 a.m. on the date both spouses are domiciled in this state; and 12:01 a.m. on 1 January 1986. A couple married in Milwaukee in 1974 has a determination date of 1 January 1986. A couple who married in Illinois in 2001 and moved to Madison in 2019 has a determination date in 2019. That date, not the wedding, is when marital property starts accumulating, and it is the first fact any Wisconsin classification question needs.
Is my spouse’s debt automatically my problem in Wisconsin?
No, and this is the point most summaries get wrong. Only some obligations reach everything. Under s. 766.55(2)(b) an obligation incurred in the interest of the marriage or the family may be satisfied from all marital property and all other property of the incurring spouse. But s. 766.55(2)(d) says any other obligation incurred during marriage may be satisfied only from that spouse’s non-marital property and that spouse’s interest in marital property, in that order. The non-incurring spouse’s half is not in the second list. Which list an obligation falls into is a legal question for a Wisconsin attorney.
What is the statement a spouse can sign at the time of borrowing?
Section 766.55(1) creates a presumption that an obligation incurred during marriage was incurred in the interest of the marriage or the family, and then adds something unusual: a statement separately signed by the incurring spouse at or before the time the obligation is incurred, saying the obligation is or will be in that interest, is conclusive evidence of it. Conclusive, not rebuttable. The section preserves interspousal remedies, but as between the creditor and the marital estate the question is closed by a signature. That document is worth looking for.
Can one spouse make the income from their own property individual property?
Yes, unilaterally, under s. 766.59. Income attributable to property that is not marital property is ordinarily marital property under s. 766.31(4); a spouse may sign a written statement, acknowledged by a notary, classifying that income as individual property. Section 766.59(2)(b) requires the executing spouse to notify the other within five days by personal delivery or certified mail, and failure to do so is a breach of the good-faith duty in s. 766.15. The statement may be recorded with a register of deeds, and s. 766.59(5) treats it as a marital property agreement so far as third parties are concerned.
Does a marital property agreement bind a bank that never saw it?
Generally not. Section 766.55(4m) provides that no provision of a marital property agreement, and no provision of a decree under s. 766.70, adversely affects a creditor’s interest unless the creditor had actual knowledge of that provision when the obligation was incurred, or when an open-end plan was entered into. Later knowledge does not help. Section 766.57(3) runs in the same direction for buyers: marital property purchased in good faith from the spouse who had the right to manage and control it is acquired free of the other spouse’s claim, and s. 766.57(2) says notice of the agreement or of the marriage itself does not defeat that status.
What happens to marital property when a Wisconsin spouse dies?
It depends on how it was held. Under s. 766.60(5)(a), property held as survivorship marital property vests solely in the surviving spouse at death by nontestamentary disposition, and the first deceased spouse may not dispose of any interest in it at all. Section 766.60(5)(c) then adds a rule creditors should know: a judgment lien on one spouse’s interest in survivorship marital property does not defeat the survivorship, and if execution was not issued before the death the survivor takes free of the lien — unless the lien reached both spouses’ interests and all the property was available under s. 766.55 anyway.
What is deferred marital property, and why does it matter to a survivor?
It is the answer to the problem the determination date creates. Property a couple built up while married but before their determination date was never classified by ch. 766, so a surviving spouse could hold no automatic half of it. Section 861.02(1) lets that survivor elect up to fifty percent of the augmented deferred marital property estate, and s. 861.02(2)(a) presumes an asset is deferred marital property once the s. 766.31(2) marital-property presumption has been rebutted. Section 861.02(2)(b) reaches property wherever it was acquired, was located at the time of a transfer, or sits now, including real property in another jurisdiction. Whether an election is available in a particular estate is a Wisconsin lawyer’s question.
What will you not do on a Wisconsin file?
We will not classify anything. Whether an item is marital property under s. 766.31 or individual property, and whether an obligation was incurred in the interest of the marriage or the family under s. 766.55(2)(b), are legal conclusions for a Wisconsin attorney and a Wisconsin court. We will not misrepresent who is asking in order to obtain a document, and we will not look inside anyone’s account. No one on this team is a lawyer or a licensed private investigator. This is no credit bureau either, so what we hand you is nobody’s consumer report and cannot lawfully decide a hire, a lease, a loan or a policy. And we turn down any request that looks like an attempt to locate someone who is hiding for their safety, including anyone enrolled in the Safe at Home programme under Wis. Stat. 165.68.
Start From the Date, Not From the Wedding
Section 766.01(5) decides when Wisconsin’s marital property system started for a particular couple, and s. 766.55 decides which half of it a creditor may reach. Both answers live in register of deeds indexes, DFI filings and court records. Say which counties are involved and why the law permits the search. Those instruments come back carrying their filing dates and an honest note on how far we actually got, and for a legitimate matter that is usually within 24 hours.
