Relating to: calculation of miles for purposes of relocation of a child 100 miles or more from the other parent in an action affecting the family.

AB 123 defines "driving miles" as the actual road distance between locations and requires parents with court-ordered physical placement to seek court permission before relocating more than 100 driving miles from the other parent. If parents already live more than 100 miles apart, relocation only requires 60 days' written notice (including new address and move date) instead of a court motion. The bill allows parents to agree on relocation through a stipulation, which the court may incorporate into an order unless it deems the change not in the child's best interest. This directly affects parents in Wisconsin family court cases involving child custody and relocation disputes.
