Wisconsin Divorce With Children — Custody & Support

Custody, child support, and parenting plans when children are involved in an Wisconsin divorce

When children are involved, a Wisconsin divorce must address custody, visitation, and child support in addition to property division and spousal support. Courts prioritize the Best interests of the child in every decision §767.41.

💡The presence of children increases the complexity of a divorce. Both parents must provide financial disclosures, and the court requires a parenting plan before it will finalize the case.

How custody is determined §767.41

Courts determine legal custody and physical placement based on the best interests of the child, with a presumption that maximum placement with each parent is in the child's best interests unless a factor weighs against it.

Types of custody

  • Legal custody — the right to make major decisions about the child's education, health care, and welfare
  • Physical custody — where the child lives day-to-day
  • Joint custody — both parents share legal custody, physical custody, or both
  • Sole custody — one parent has primary decision-making authority or residential time

Child support

Wisconsin uses an percentage-of-income model to calculate child support.

  • Based on a percentage of the payer's gross income: 17% for 1 child, 25% for 2, 29% for 3, 31% for 4, 34% for 5+ children
  • Percentage may be adjusted for shared-placement arrangements
  • Deviation from the guidelines requires written findings
  • Income can be withheld directly from the paying parent's employer §767.75

The parenting plan

Most Wisconsin courts require a written parenting plan that addresses:

  • Regular custody and visitation schedule
  • Holiday and vacation time allocation
  • Transportation arrangements and exchange locations
  • Decision-making authority for education, health, and extracurricular activities
  • Communication protocols between parents
  • Relocation restrictions and notice requirements

Temporary orders during the divorce §767.225

Courts may issue temporary orders for maintenance, child support, legal custody, physical placement, and exclusive use of the marital home during the proceedings. Temporary custody and support orders typically remain in effect until the final decree is entered.

✓Document the current parenting arrangement before filing. Courts consider the existing status quo when making temporary and permanent custody decisions.

Modifying custody later

Custody may be modified upon showing that circumstances have substantially changed since the last order and modification is in the child's best interests; within 2 years, modification requires a showing of physical or emotional harm. §767.451

⚠If there is an immediate safety concern involving a child, the court can issue emergency orders on an expedited basis. Do not wait if a child's welfare is at risk.
