MO HB1318

Defines "relocation" as a change in a child's principal residence for 90 days or more, excluding temporary absences.

Requires written notice by certified mail at least 60 days in advance of a proposed relocation to any party with custody or visitation rights, including the new address, phone number, move date, reasons, and proposed custody adjustments.

Allows relocation to proceed 60 days after notice unless a parent files a motion within 30 days to prevent it, with the relocating parent bearing the burden of proving the move is in good faith and in the child's best interest.

When relocation is permitted, courts must ensure the non-relocating parent has frequent, continuing, and meaningful contact with the child, and must allocate transportation costs and adjust child support accordingly.

Failure to provide proper relocation notice can result in custody modification, return of the child, payment of the other party's reasonable expenses and attorney fees, and contempt of court.
