The parent of a minor may appoint by will a guardian of an unmarried minor. A testamentary appointment becomes effective upon filing the guardian’s acceptance in the court in which the will is probated and remains effective upon approval by the court either after or without a hearing, if, before acceptance, both parents are dead or the surviving parent’s rights have been terminated by prior court order. If both parents are dead, an effective appointment by the parent who died later has priority. This state recognizes a testamentary appointment effected by filing the guardian’s acceptance under a will probated in another state which is the testator‘s domicile and upon approval by the court either after or without a hearing. Upon acceptance of appointment, written notice of acceptance must be given by the guardian to the minor and to the person having the minor’s care or to the minor’s nearest adult relative under section 27-20.3-02. Within forty-five days of the filing of acceptance, the testamentary guardian must file with the court a criminal history record check report and affidavit stating whether the proposed guardian has been investigated for offenses related to theft, fraud, or the abuse, neglect, or exploitation of an adult or child and shall provide a release authorizing access to any record information maintained by an agency in this or another state or a federal agency.
