No such proceeding

Generally, a person may become a minor's guardian "by acceptance of a testamentary appointment [made by the minor's parent] or upon appointment by the court." Mont. Code Ann. § 72-5-201.  A court is permitted to "appoint a guardian for an unmarried minor if all parental rights of custody have been terminated or if parental rights have been suspended or limited by circumstances or prior court order." § 72-5-222(1).

Accordingly, because there appears to be no method of appointing a guardian for a minor child through the probate code absent a separate proceeding having occurred that terminated parental rights, this development is classified as "No such proceeding."
