6 months in Wisconsin and 30 days in the county where you file, then a mandatory 120 days. Wisconsin does grant legal separation.
Wisconsin divorce runs on a handful of state-specific rules that shape almost everything else — how property gets divided, how long the case will take, and what a court will expect you to disclose. Knowing these before you file saves confusion later.
| Residency requirement | At least one spouse must have lived in Wisconsin for 6 months and in the county where you file for 30 days immediately before filing (Wis. Stat. § 767.301). |
|---|---|
| Grounds | No-fault only — one spouse states under oath that the marriage is irretrievably broken. Wisconsin does not require or weigh evidence of fault. |
| Waiting period | A mandatory 120 days: from filing for a joint petition, or from service on the other spouse for a solo petition. No judgment can be entered before then, even if both spouses agree on every term. |
| Legal separation | Wisconsin does grant legal separation. It settles the same questions a divorce settles — support, parenting and, depending on the case, property — but leaves the marriage in place, so neither spouse can remarry without a divorce. |
| If you were never married | Wisconsin does not create common-law marriage, and living together gives neither partner property or support rights. Claims rest on agreements between you. A common-law marriage validly formed in a state that does create them is generally still recognised. |
| Where you file | The Clerk of Circuit Court in the Wisconsin county where you or your spouse resides, under Chapter 767 of the Wisconsin Statutes. |
| Filing fee | Payable when you file your opening divorce document. Set locally by the county, not as one statewide rate. A fee waiver is available if you cannot afford it. Filing fees are set by the court and change without notice: check the current schedule on the court's own website before you file, and ask about a fee waiver if the cost is a barrier. |
| Starting forms | Solo filing: Summons (FA-4104V with minor children / FA-4105V without) and Petition (FA-4108V / FA-4109V). Joint filing: Joint Petition (FA-4110V with minor children / FA-4111V without). Every case also requires the confidential Form GF-179 addendum. |
| Simplified option | Yes — a Joint Petition (FA-4110V/FA-4111V) lets both spouses file together and skip formal service. The court's online Family/Divorce Forms Self-Help Assistant on wicourts.gov walks you through the questions and fills in most of the required forms. |

Wisconsin is one of the few states that treats marital property as community property, through the Marital Property Act. In practice, this means most property and income acquired by either spouse during the marriage is presumed to belong to both of them equally, regardless of whose name is on the account, title, or paycheck. That presumption can generally be rebutted for property owned before the marriage, or received individually as a gift or inheritance — but the burden is on the spouse claiming it's separate, and courts expect documentation, not just a claim.
Divorce cases are filed in the Circuit Court for the county where a spouse resides, under Chapter 767 of the Wisconsin statutes. Wisconsin is a no-fault state — the only ground is that the marriage is 'irretrievably broken' — so there's generally no need, and little benefit, to litigating who caused the breakdown.
One rule surprises a lot of people: Wisconsin imposes a mandatory 120-day waiting period from the date the divorce petition is filed (or served) before a judgment can be finalized, even if both spouses agree on every term. This isn't a delay tactic anyone can shorten by cooperating faster — it's a statutory floor. Understanding that up front helps set realistic expectations about pace, and takes the pressure off rushing early decisions.
Wisconsin divorce cases generally require each spouse to complete a sworn Financial Disclosure Statement early in the case, so the sooner you start collecting the underlying paperwork, the smoother that step goes. Useful documents to gather: recent tax returns, pay stubs, and statements for every bank, retirement, and investment account; mortgage statements and deeds for any real estate; vehicle titles; and records for any business interest, including its financials if either spouse owns or co-owns one.
If you believe part of what you own should be treated as individual property rather than marital property — something you owned before the marriage, or received as a gift or inheritance — start pulling the paper trail now: purchase records, the original gift or estate documents, and anything showing the asset was kept separate rather than mixed with joint funds. In a community-property state, that tracing evidence often matters more than it would elsewhere.
Wisconsin courts address two related but distinct questions for children: legal custody (decision-making authority, generally favored to be joint absent specific concerns) and physical placement (where the children live and on what schedule). Courts decide both based on the best interests of the child, and a detailed, workable placement proposal tends to go further than a vague one.
Child support is calculated using Wisconsin's Child Support Percentage of Income Standards, with a different formula applied when placement is shared roughly equally between parents. Spousal maintenance, by contrast, isn't set by a fixed formula — courts weigh factors like the length of the marriage and each spouse's earning capacity, so proposals here vary more from case to case.
Legal separation is available in Wisconsin. It is a court proceeding, and in most respects it runs like a divorce: the court can settle support, parenting arrangements and, depending on the case, the division of property, and the resulting order binds both spouses.
What it does not do is end the marriage. People choose it for a range of reasons — health coverage, religious conviction, immigration status, or simply not being ready — and it leaves the door open to reconciling without starting over.
Two consequences follow. Neither spouse can remarry unless they later obtain a divorce, and modifying the order generally takes the court's approval rather than a private agreement between you. If you expect to divorce eventually, ask what converting the separation into a divorce involves here before you start.
Wisconsin does not create common-law marriage. There is no number of years of living together that turns into a marriage here, and none of the divorce machinery on this page applies to a couple who never married — no property division, no spousal support, no residency requirement to satisfy, because there is nothing to dissolve.
What unmarried partners have instead are ordinary civil claims: whatever you agreed between yourselves, in writing or by clear conduct, and claims over property you actually hold jointly. These are argued like any other contract or property dispute rather than as family-law entitlements, and they turn on what can be proved.
One qualification runs the other way and matters. A common-law marriage validly formed in a state that does create them — Colorado, Iowa, Kansas, Montana, Oklahoma, Rhode Island, Texas or Utah — is generally recognised elsewhere. A couple who met that state's test while living there, and later moved here, are married, and separating means divorcing. Children are unaffected either way: custody and child support are decided on the same basis whether or not the parents married.
1) Start your financial disclosure documents early, since Wisconsin requires a sworn statement rather than an informal exchange. 2) Sort your property into 'clearly marital,' 'clearly individual,' and 'need to check,' and pull the tracing paperwork for anything in that last two categories now, before memories or receipts go missing. 3) Get oriented on the 120-day timeline so you're planning around it rather than surprised by it — it applies whether the case is contested or fully agreed. 4) If children are involved, sketch a realistic placement schedule early; it's easier to negotiate from a concrete proposal than react to someone else's. 5) From the first letter you receive — whether from the other spouse's lawyer or the court — keep track of every date and every position stated, since Wisconsin's waiting period means these cases often unfold over several months of correspondence.
Before filing anything, confirm at least one spouse has lived in Wisconsin for 6 months and in the county where you plan to file for 30 days. Filing too early can get the case dismissed for lack of jurisdiction, so it's worth confirming before you spend time on paperwork.
If you and your spouse agree on the basics, a Joint Petition (FA-4110V with minor children, FA-4111V without) lets you file together and skip formal service. If you're filing alone, you'll use a Summons (FA-4104V or FA-4105V) and Petition (FA-4108V or FA-4109V) instead, and the other spouse must be formally served.
Every Wisconsin divorce needs the confidential Form GF-179 addendum (Social Security numbers and dates of birth, filed under seal) in addition to the petition and summons. The Wisconsin Court System's online Family/Divorce Forms Self-Help Assistant on wicourts.gov walks you through the questions and generates most of these forms for you.
File the completed forms with the Clerk of Circuit Court in the correct county. Expect a filing fee set by the court, higher if you are requesting child support or maintenance — confirm the exact current amount with the clerk, since fees can change. Ask about a fee waiver if you can't afford it.
In a solo filing, the other spouse must be formally served with the summons and petition; the 120-day waiting period starts from the date of service, not the date you filed. In a joint petition, both spouses have already signed on, so there's no separate service step and the clock starts at filing.
Both spouses generally must complete and exchange a sworn Financial Disclosure Statement early in the case. Start gathering tax returns, pay stubs, and account statements as soon as you can so this doesn't become the thing that stalls your case.
If you have children, you'll need a proposed legal custody and physical placement schedule; property and debts get divided under Wisconsin's marital property rules. Courts expect specifics, not vague intentions, so a written proposal carries weight.
Wisconsin law requires a minimum 120 days between filing (or service) and judgment, regardless of how quickly you and your spouse agree on terms. Use this time to finish disclosures, respond to any court deadlines, and prepare for the final hearing.
Once the waiting period has passed and paperwork is complete, the court holds a final hearing (often brief and uncontested if every issue is resolved) and enters the Findings of Fact, Conclusions of Law and Judgment of Divorce, which officially ends the marriage.
Yes. Under the Marital Property Act, property and income acquired during the marriage is generally presumed to belong to both spouses equally, though property owned before the marriage or received individually as a gift or inheritance can generally be classified as separate if you can document it.
At minimum 120 days from filing, since Wisconsin law sets that as a mandatory waiting period before a judgment can be entered — even in fully agreed cases. Contested cases, or ones with complex property or custody disputes, often take longer.
No. Wisconsin is a no-fault state — the only ground for divorce is that the marriage is irretrievably broken, so courts generally don't require or weigh evidence of fault.
A legal separation in Wisconsin settles much of what a divorce settles — support, parenting and, depending on the case, property — and the order binds both spouses. The difference is that it does not end the marriage, so neither spouse can remarry without later obtaining a divorce. People use it for health coverage, religious reasons, immigration status, or because they are not ready to divorce. Changing the order generally requires the court's approval.
No. Wisconsin does not create common-law marriage, and living together for any length of time gives neither partner property division nor spousal support. Unmarried partners rely instead on agreements between themselves and on claims over jointly held property, argued as ordinary civil matters. One important exception: a common-law marriage validly formed in a state that does create them — such as Colorado, Iowa, Kansas, Montana, Oklahoma, Rhode Island, Texas or Utah — is generally recognised here, so that couple would need a divorce. Custody and child support apply regardless of marriage.
