In determining the Indian child's tribe: (A) The court shall ask each participant in an emergency or voluntary or involuntary child-custody proceeding whether the participant knows or has reason to know that the child is an Indian child.

The court shall order the party to provide the information no later than seven business days after the date of the hearing or prior to the next hearing on the matter, whichever occurs first. The information should be filed with the court and provided to the county department of human or social services and each party no later than seven business days after the date of the hearing.(II) The court, upon conducting the inquiry described in subsection (1)(a)(I) of this section, has reason to know that a child is an Indian child if:(A) Any participant in the child-custody proceeding, officer of the court involved in the child-custody proceeding, Indian tribe, Indian organization, or agency informs the court that the child is an Indian child;(B) Any participant in the child-custody proceeding, officer of the court involved in the child-custody proceeding, Indian tribe, Indian organization, or agency informs the court that it has discovered information indicating that the child is an Indian child;(C) The child who is the subject of the child-custody proceeding gives the court reason to know he or she is an Indian child;(D) The court is informed that the domicile or residence of the child, the child's parent, or the child's Indian custodian is on a reservation or in an Alaska native village;(E) The court is informed that the child is or has been a ward of a tribal court, as defined in 25 U.S.C. sec. 1903; or(F) The court is informed that the child or the child's parent possesses an identification card indicating membership in an Indian tribe.(b) If the court knows or has reason to know, as defined in subsection (1)(a)(II) of this section, that the child who is the subject of the proceeding is an Indian child, the petitioning or filing party shall send notice by registered or certified mail, return receipt requested, to the parent or parents, the Indian custodian or Indian custodians of the child and to the tribal agent of the Indian child's tribe as designated in 25 CFR 23, or, if there is no designated tribal agent, the petitioning or filing party shall contact the tribe to be directed to the appropriate office or individual. In providing notice, the court and each party shall comply with 25 CFR 23.111.(c) The petitioning or filing party shall disclose in the complaint, petition, or other commencing pleading filed with the court that the child who is the subject of the proceeding is an Indian child and the identity of the Indian child's tribe or what efforts the petitioning or filing party has made in determining whether the child is an Indian child. If the child who is the subject of the proceeding is determined to be an Indian child, the petitioning or filing party shall further identify what reasonable efforts have been made to send notice to the persons identified in subsection (1)(b) of this section. The postal receipts indicating that notice was properly sent by the petitioning or filing party to the parent or Indian custodian of the Indian child and to the Indian child's tribe must be attached to the complaint, petition, or other commencing pleading filed with the court; except that, if notification has not been perfected at the time the initial complaint, petition, or other commencing pleading is filed with the court or if the postal receipts have not been received back from the post office, the petitioning or filing party shall file the postal receipts with the court. Any responses sent by the tribal agents to the petitioning or filing party, the county department of human or social services, or the court must be distributed to the parties and deposited with the court.(2) If there is reason to know the child is an Indian child but the court does not have sufficient evidence to determine that the child is or is not an Indian child, the court shall: (a) Confirm, by way of a report, declaration, or testimony included in the record, that the petitioning or filing party used due diligence to identify and work with all of the tribes of which there is reason to know the child may be a member, or eligible for membership, to verify whether the child is in fact a member, or a biological parent is a member and the child is eligible for membership; and(b) Treat the child as an Indian child, unless and until it is determined on the record that the child does not meet the definition of an Indian child.(3) If the court receives information that the child may have Indian heritage but does not have sufficient information to determine that there is reason to know that the child is an Indian child pursuant to subsection (1)(a)(II) of this section, the court shall direct the petitioning or filing party to exercise due diligence in gathering additional information that would assist the court in determining whether there is reason to know that the child is an Indian child. The court shall direct the petitioning or filing party to make a record of the effort taken to determine whether or not there is reason to know that the child is an Indian child.(4) The requirements of the federal "Indian Child Welfare Act of 1978", 25 U.S.C. sec. 1901 et seq., in effect as of February 9, 2003, and the related regulations located at 25 CFR 23, in effect as of February 9, 2023, are incorporated into and adopted as state law.Amended by 2023 Ch. 150,§ 1, eff. 5/4/2023.Amended by 2019 Ch. 305, § 2, eff. 5/28/2019.Amended by 2018 Ch. 38, § 33, eff. 8/8/2018.L. 2002: Entire section added, p. 784, § 3, effective May 30.
