CasewellThe law in plain words
Under Wis. Stat. § 767.41, "the court shall presume that joint legal custody is in the best interest of the child."
Wondering who usually ends up with custody? Our page on the chances of getting full custody in Wisconsin explains what the figures can and cannot show.
Legal custody and physical placement
Wisconsin law splits every case into two separate questions, each with its own name.
- Legal custody: the right to make major decisions. The law lists health care that is not an emergency, school and religion, among others.
- Joint legal custody: both parents share those decisions, and neither has the final word. A court can still give one parent certain decisions.
- Sole legal custody: one parent makes the major decisions alone.
- Physical placement: the time a child is with a parent. During that time, the parent makes routine daily decisions.
- Primary placement: where the child lives most of the time.
A parent can share legal custody and still have less placement. Each parent can see the child's medical, dental and school records, unless a court orders otherwise.
Is Wisconsin a 50/50 state?
No. Wisconsin presumes joint decision-making, not equal time.
- Legal custody: joint legal custody is the starting point in a first order.
- Placement: the schedule must give regular, meaningful time with each parent. It must also maximize each parent's time, given distance and the two households.
- Not a 50/50 rule: court decisions noted in the official statutes say this duty is not a presumption of equal placement.
- Under 25%: if one parent gets less than 25% of the time, the judge must explain why in written findings.
Bills filed in 2025 would have presumed equal placement. They did not pass before the session ended in 2026.
The best-interest factors
Under § 767.41(5)(am), the court must weigh these factors. They are not ranked.
- what each parent wants, shown by agreements or proposed parenting plans
- what the child wants, told directly or through the guardian ad litem
- how well the parents cooperate and communicate, and whether one refuses without good reason
- whether each parent supports the child's bond with the other, or is likely to interfere
- the child's bonds with siblings and others who matter to the child
- the child's bond with each parent, and how much time each has spent with the child
- any serious alcohol or drug problem of a parent, a dating partner or a household member
- how settled the child is at home, at school, in their religion and in the community
- the child's age and changing needs
- any physical or mental health problem in the household that harms the child
- any criminal record, child abuse or neglect by a parent, dating partner or household member
- any evidence of battery or domestic abuse
- reports from professionals, if admitted as evidence
- anything else the judge finds relevant
The court may not prefer a parent because of sex or race. If the case is contested, the judge must explain the decision in writing.
Your child's preference
Wisconsin sets no age at which a child chooses. The child's wishes are one factor among 14.
- The guardian ad litem: this is a lawyer for the child's best interests. They tell the court what the child wants, unless the child asks them not to.
- Not bound: the guardian ad litem weighs the child's wishes but can recommend something else.
- Mediation: a court mediator may interview the child, with or without a parent present.
The judge makes the final decision.
Mothers' and fathers' rights
Married parents start equal. The law forbids preferring a parent because of sex, and joint legal custody is presumed for both.
Unmarried parents are different. The mother has sole legal custody until a court rules, so an unmarried father must go to court.
Once he does, the same 14 factors apply to both parents. A father's past caregiving and his plans for the child matter as much as a mother's.
A possible call to active military duty cannot count against a parent in a legal custody decision.
If you were never married
Under § 767.82(2m), the mother has sole legal custody of a child born outside marriage. That lasts until a court orders otherwise.
This stays true even after paternity is acknowledged or shown by genetic tests. The father's name on the birth record does not, by itself, give him legal custody or a placement schedule.
- Voluntary Paternity Acknowledgment: both parents can sign it at the hospital or later. It cannot be used if the mother was married to another man at conception or birth.
- Changing your mind: either signer can rescind it within a short window set by law. After that, it has the same effect as a court judgment.
- Undoing it later: a court can void it for fraud, threats or pressure, or a mistake of fact.
- No acknowledgment: a parent or the county child support agency can start a paternity case. It must be brought before the child turns 19.
After an acknowledgment, either parent can file directly for legal custody and placement. A paternity judgment must also include custody and placement orders.
Domestic violence
Abuse changes the starting point. If the court finds a pattern or serious incident of domestic abuse or battery, the joint custody presumption no longer applies.
- Presumption against custody: it is presumed harmful to give that parent joint or sole legal custody.
- Rebutting it: the parent must finish a certified batterer treatment program and not be abusing alcohol or drugs. Custody must also serve the child.
- Both parents violent: the court decides who was the primary physical aggressor. If only one has a domestic abuse conviction against the other, that parent is.
- Safety first: the child's safety and the victim's safety become the main concerns.
- Placement conditions: the court must order protections, such as supervised time, safe exchanges, no overnights or a bond.
Evidence of abuse also creates a presumption that parents cannot share decisions. A parent abused by the other can give a general area, not an exact address, in a parenting plan.
Emergency and temporary orders
Wisconsin family law does not use the phrase "emergency custody." The tools are temporary orders and, where abuse is involved, a domestic abuse injunction.
- Temporary orders: while a case is open, the judge can set temporary legal custody and placement. They do not bind the final decision.
- Sole custody: a temporary order can give one parent sole legal custody without the usual findings.
- 30 days: the court must rule on a request for temporary placement within 30 days of filing.
- Same factors: temporary decisions use the same best-interest factors as final ones.
- Danger: a court can deny a parent's placement at any time if it would endanger the child's health.
A domestic abuse restraining order and injunction comes from section 813.12. Ask the clerk of circuit court or a local domestic violence program for help.
Moving with your child
Under § 767.481, a parent needs court permission to move 100 miles or more from the other parent. This applies when both parents have court-ordered placement.
- File a motion with a relocation plan: the date, the new town, the reason and a proposed schedule.
- Mail it to the other parent, with an Objection to Relocation form.
- Initial hearing: the court holds one within 30 days. The child may not move before it.
- If the other parent objects: the case goes to mediation, a guardian ad litem is usually appointed, and a further hearing follows within 60 days.
The moving parent usually carries the burden. Two presumptions favor the move: the objecting parent rarely used their placement, or the move relates to abuse.
If parents already live over 100 miles apart, give 60 days' written notice instead. Taking the child away for over 14 days in a row needs notice too.

Changing custody
Under § 767.451, the timing of your request matters.
- Within two years of the final order: a big change needs substantial evidence that current conditions harm the child physically or emotionally.
- After two years: you must show a substantial change in circumstances, and that the change serves the child.
- The status quo: the law presumes keeping current decision-making, and the child's main home, is best.
- Equal schedules: if equal time has become impractical, the court can change it on best interests alone.
- Not enough alone: a change in income or a new marriage does not justify a change.
Smaller schedule changes need only best interests. If a parent keeps skipping placement, the court can adjust their time at any point.
When placement is denied, a parent can file an enforcement motion. The court must order make-up time and fees if denial was intentional and unreasonable.
Mediation, parenting plans and classes
Contested cases go to mediation first. Wisconsin calls the county office that runs it family court services.
- Mediation: parents must attend at least one screening session. The court can waive it for undue hardship or danger, including abuse.
- Parenting plan: each parent sends a proposed plan to the mediator at least 10 days before the first session.
- Late plans: if mediation fails or is waived, plans are due within 60 days. A parent who misses this can lose the right to object to the other plan.
- Guardian ad litem: if mediation does not settle it, the court usually appoints one. Parents normally pay their fees.
- Custody study: the court can order an investigation of each home and each parent's role.
- Classes: the court can order a parenting program of up to four hours. If a parent refuses a class, the court may refuse to hear their custody motions.
How to file for custody in Wisconsin
Cases are filed with the clerk of circuit court in your county.
- Choose the case type. Married parents file for divorce or legal separation. Unmarried parents with an acknowledgment file for custody and placement. Others start a paternity case.
- Get the forms. The Wisconsin court system publishes statewide family forms. Your county clerk of circuit court has packets too.
- File and pay the fee with the clerk, or ask for a fee waiver.
- Serve the other parent with the papers.
- Attend mediation screening and submit your proposed parenting plan.
- If no agreement, expect a guardian ad litem, perhaps a study, then a hearing.
The Wisconsin State Law Library custody page links the official forms and county guides. Your county child support agency may help start a paternity case.

What changed recently
- November 1, 2026: court filing fees and surcharges rise under 2025 Wisconsin Act 179, signed April 3, 2026. Family filings, motions, mediation and custody studies all cost more.
- March 2026: bills to presume equal placement, Assembly Bill 151 and Senate Bill 161, did not pass before the session ended.
- 2021-22 session: the last changes to the custody and placement section, per the official statutes' history note.
- April 5, 2018: the current relocation rules took effect for new cases, and for older cases modified after that date.
We found no 2025 or 2026 act changing the custody and placement sections themselves. Last checked October 27, 2026. Laws can change, so check before you rely on this.
Building the record
Wisconsin judges weigh the time each parent has spent with the child, and how the parents cooperate. Both are answered with dates and messages, not memories.
Note each placement period, exchange and school or doctor task as it happens. Casewell keeps those notes and the messages behind them together, so a lawyer can read a clear timeline.
Before you record a call or a handover, check whether you can record your co-parent in Wisconsin.

Is Wisconsin a 50/50 custody state?
No. Joint legal custody, meaning shared decision-making, is the legal starting point. Placement time is set on the child's best interests, with no presumption of equal time.
Who has custody if the parents are not married in Wisconsin?
The mother has sole legal custody until a court orders otherwise. That stays true after a paternity acknowledgment, so a father must file to get custody or placement.
At what age can a child decide where to live in Wisconsin?
There is no set age. The child's wishes are one of 14 factors, often passed on by the guardian ad litem, and the judge decides.
How far can I move with my child in Wisconsin?
If both parents have court-ordered placement, moving 100 miles or more from the other parent needs court permission. You must file a motion with a relocation plan first.
How much does it cost to file for custody in Wisconsin?
A paternity case is listed at $184.50, or $194.50 with a support request. A change motion is $50. These rise on November 1, 2026.
Can you change custody within two years in Wisconsin?
Only with substantial evidence that current conditions harm the child physically or emotionally. After two years, you must show a substantial change in circumstances.
