Montana Relocation Statute

          Mont. Code Ann. § 40-4-217

§ 40-4-217.  Notice of intent to move.

   (1)  A parent who intends to change residence shall, unless precluded under 40-4-234, provide written notice to the other parent.

(2)  If a parent's change in residence will significantly affect the child's contact with the other parent, notice must be served personally or given by certified mail not less than 30 days before the proposed change in residence and must include a proposed revised residential schedule. Proof of service must be filed with the court that adopted the parenting plan. Failure of the parent who receives notice to respond to the written notice or to seek amendment of the residential schedule pursuant to 40-4-219 within the 30-day period constitutes acceptance of the proposed revised residential schedule.
