The Wisconsin FA-4170V Notice of Motion and Motion to Change: Legal Custody, Physical Placement, Child Support or Spousal Maintenance is a legal document used in Wisconsin to notify a court of a motion to change legal custody, physical placement, child support or spousal maintenance. The FA-4170V must be filed in the circuit court of the county in which the child resides, and the filing party must also serve the other parties with a copy of the form.

This could include a change from one parent's home to the other, or a change in the amount of time the child spends with each parent. 3. Motion to Change Child Support or Spousal Maintenance: This motion is used to request a change in the amount of child support or spousal maintenance. This could include a change in the amount of support paid, or a change in the payment schedule.
