Wisconsin Divorce With Children — Physical Placement and Child Support (2026)

Wisconsin uses distinct terminology for child custody matters. Using the correct terms on forms and in agreements is essential.

Wisconsin Terminology: Two Key Terms

Legal Custody

Authority to make major decisions about the child's upbringing — education, healthcare, religious training, extracurricular activities, and other significant matters.

• Joint legal custody: Both parents share major decisions — most common in Wisconsin
• Sole legal custody: One parent has final authority — ordered when joint legal custody is impractical (domestic violence, inability to communicate, etc.)

Physical Placement

Where the child resides and when. Wisconsin does NOT use the term "physical custody" or "parenting time" — the correct Wisconsin term is physical placement.

• Primary physical placement: Child resides primarily with one parent; other parent has a set placement schedule
• Shared physical placement: Child has substantial placement time with both parents (affects child support calculation)

Never use "custody" to mean parenting time in Wisconsin documents — use "physical placement."

Best Interest Standard — Wis. Stat. § 767.41

Courts determine physical placement and legal custody based on the best interests of the child, weighing:

1. Wishes of the child
2. Wishes of each parent
3. Relationship of the child with each parent and siblings
4. Amount of quality time each parent has spent with the child
5. Child's adjustment to home, school, and community
6. Mental and physical health of the parties
7. Availability of child care
8. Whether either parent has or intends to relocate
9. Child's developmental and educational needs
10. Cooperation of each parent in maintaining a relationship with the other
11. Each party's support for the child having a meaningful relationship with the other parent

Wisconsin Child Support

Wisconsin uses a percentage of income formula:

The percentage applies to the payer's gross monthly income adjusted for pre-existing child support obligations.

Shared placement adjustment: If the non-primary parent has 25%+ of the overnights (92+ nights/year), a shared placement formula applies — typically resulting in a reduced child support obligation.

Duration: Child support in Wisconsin ends when the child turns 18 (unless still enrolled in high school — then 19).

Parenting Plan Requirements

The Parenting Plan must address:

• Legal custody (joint or sole)
• Primary physical placement designation
• School-year physical placement schedule (specific days, exchange times and locations)
• Summer physical placement schedule
• Holiday placement schedule (specific holidays listed for each parent)
• School breaks and long weekends
• Vacation advance notice
• Communication: phone/video with non-primary parent
• Transportation: who drives exchanges
• Relocation: Wisconsin requires advance notice before relocating with children — include the applicable notice period (check current Wisconsin statute)

Impact on the 120-Day Period

Having children in the case does not change the 120-day waiting period — it still runs from the service date (or joint petition filing date). Courts will not finalize physical placement or child support orders before Day 121.

Temporary orders for physical placement and child support can be requested during the 120-day period if needed for immediate stability.
