Montana Title 40. Family Law § 40-4-217. Notice of intent to move

(2)(a) If a parent's change in residence will significantly affect the child's contact with the other parent, the parent who intends to change residence shall, pursuant to 40-4-219, file a motion for amendment of the residential schedule and a proposed revised residential schedule with the court that adopted the residential schedule or the court to which jurisdiction or venue over the child has been transferred. The motion must be served personally or by certified mail on the other parent and served pursuant to the Montana Rules of Civil Procedure on the parent's attorney of record, if the parent has an attorney of record, not less than 30 days before the proposed change in residence.

(b) The notice pursuant to this subsection (2) is not sufficient unless it contains the following statement: “The relocation of the child may be permitted and the proposed revised residential schedule may be ordered by the court without further proceedings unless within 21 days you file a response and alternate revised residential schedule with the court and serve your response on the person proposing the move and all other persons entitled by the court order to residential time or visitation with the child.”
