Wisconsin Divorce Laws (2026): Grounds, Residency, and Process
Wisconsin Divorce Laws (2026): Grounds, Residency, and Process
To get divorced in Wisconsin, at least one spouse must show the marriage is irretrievably broken, which is the only ground under Wisconsin's no-fault-only system. One spouse must have lived in Wisconsin for 6 months and in the filing county for 30 days. No separation period is required before filing, but a 120-day waiting period applies after service.
Grounds for divorce in Wisconsin
Wisconsin is a no-fault-only divorce state. The sole ground for divorce is that the marriage is irretrievably broken, as set out in Wis. Stat. 767.315. All traditional fault grounds, such as adultery or cruelty, have been abolished.
The court finds that the marriage is irretrievably broken in one of two ways. First, if both spouses testify or submit sworn statements that the marriage is irretrievably broken, the court accepts that finding. Second, if one spouse denies the breakdown, the court may find it established if the parties have voluntarily lived apart for 12 or more months and one party states under oath that the marriage is irretrievably broken.
It is important to understand that the 12-month voluntary separation is not a requirement. It is simply an alternate way to prove breakdown when the other spouse contests the case. If both spouses agree, the divorce can proceed without any period of living apart.
Because Wisconsin has eliminated fault grounds entirely, no party can allege adultery, abandonment, or cruelty as the basis for a divorce. The focus is entirely on whether the marriage has broken down beyond repair.
Residency requirement
To file for divorce in Wisconsin, at least one spouse must have been a Wisconsin resident for at least 6 months before filing. That spouse must also have been a resident of the specific county where the petition is filed for at least 30 days before filing (Wis. Stat. 767.301).
Divorce cases in Wisconsin are heard by the Circuit Court in the county where the filing spouse resides. If both spouses meet the residency requirements in different counties, either county's Circuit Court can accept the case.
There is no exception for military service members that shortens the 6-month period under Wisconsin law, though service members domiciled in Wisconsin satisfy the requirement. Residency is measured from the date the petition is filed, not from the date a hearing is scheduled.
Waiting period and separation
Wisconsin imposes a mandatory 120-day waiting period. The waiting period begins the day the respondent spouse is served with the divorce petition, and the final hearing cannot be scheduled until those 120 days have elapsed (Wis. Stat. 767.335). Courts cannot waive this period.
The 120-day waiting period is not the same as a separation requirement. A separation requirement means spouses must live apart before they can file. Wisconsin has no such requirement. You may file the day you decide to divorce, even if you are still living in the same home with your spouse.
During the 120-day window, both parties typically exchange financial disclosures, negotiate a marital settlement agreement covering property, support, and custody, and attend any required mediation. If the case is contested, additional hearings may push the timeline beyond 120 days. Uncontested divorces in Wisconsin often resolve within 4 to 6 months from filing.
How property is divided
Wisconsin is one of only nine community property states in the United States. The others are Arizona, California, Idaho, Louisiana, Nevada, New Mexico, Texas, and Washington. In a community property state, the law presumes that most property acquired during the marriage belongs equally to both spouses, and the court divides it roughly 50/50.
Community property in Wisconsin includes wages earned during the marriage, real estate purchased with marital funds, and debts incurred by either spouse for marital purposes. Property you owned before the marriage, gifts given specifically to you, and inheritances you received remain separate property and are not subject to division.
In practice, Wisconsin courts apply the community property presumption but can deviate from an equal split in limited circumstances, such as when the parties agree to a different division or when equity demands it. The governing statute is Wis. Stat. 766.31.
Separate property is yours to keep. However, if separate property was commingled with marital assets, such as depositing an inheritance into a joint account and using it for household expenses, it can become marital property over time.
Alimony, custody, and child support
Wisconsin courts decide maintenance (the state's term for alimony), legal custody, physical placement, and child support as part of the divorce case or in associated proceedings.
Maintenance is addressed under Wis. Stat. 767.56. The court considers the length of the marriage, the standard of living established during the marriage, each spouse's earning capacity, contributions to the other's education or career, and any agreement between the parties. Wisconsin does not favor permanent maintenance; rehabilitative awards are common for shorter marriages. For more detail on how courts calculate maintenance in Wisconsin, see the Wisconsin alimony laws page at /us-laws/alimony/wisconsin-alimony-laws.
Custody and physical placement are governed by Wis. Stat. 767.41. Wisconsin courts start from a presumption that both parents should have meaningful involvement in a child's life. The court uses a best-interests standard that considers the child's adjustment to home, school, and community; each parent's ability to cooperate; the child's relationship with each parent; and other relevant factors. For a full discussion see the Wisconsin child custody laws page at /us-laws/child-custody/wisconsin-child-custody-laws.
Child support is calculated under Wisconsin's percentage-of-income guidelines (DWD 40). The guidelines set presumptive percentages based on the number of children and the payer's gross income, subject to adjustment for shared or split placement arrangements.

How to file for divorce in Wisconsin
Filing for divorce in Wisconsin involves several steps that the Circuit Court's self-help resources can guide you through. Here is the general sequence.
First, confirm you meet the 6-month state residency and 30-day county residency requirements. If you do not yet qualify, wait until you do before filing.
Second, prepare and file the summons and petition for divorce with the Circuit Court clerk in your county. The Wisconsin Court System provides approved self-help forms through its website at courts.wi.gov. You will pay a filing fee at the clerk's office; the amount varies by county.
Third, serve your spouse with the summons and petition. Service can be completed by personal delivery, by a sheriff, or by a process server. The 120-day waiting period begins on the date of service.
Fourth, both parties complete a financial disclosure statement listing income, debts, and assets. If children are involved, parenting plans and a proposed placement schedule are also prepared.
Fifth, you and your spouse either reach a marital settlement agreement covering all issues or proceed to contested hearings before a judge. Mediation may be required for custody disputes.
Sixth, once the 120 days have elapsed, the final hearing is scheduled. If the settlement is complete and the court approves it, the judge signs the final judgment of divorce. The divorce is effective when the judgment is entered.
