Subd. 1. Requirements of Consent. If the child to be adopted is an Indian child, the consent of the parent or Indian custodian shall not be valid unless:
Subd. 2. Revocation of Consent to Adoption of an Indian Child. In any voluntary proceeding for adoptive placement of an Indian child, the consent of the parent may be withdrawn for any reason at any time prior to the entry of an adoption decree and the child shall be returned to the parent.
Subd. 3. Vacation of an Adoption Decree of an Indian Child. After the entry of an adoption decree of an Indian child in any State court, the parent may withdraw consent thereto upon the grounds that consent was obtained through fraud or duress and may petition the court to vacate such decree. Upon a finding that such consent was obtained through fraud or duress, the court shall vacate such decree and return the child to the parent. No adoption of an Indian child which has been effective for at least two (2) years may be invalidated under the Indian Child Welfare Act, 25 U.S.C. § 1913, unless otherwise permitted under state law.
Minn. R. Adop. P. 33.09
Rule 33.09 mirrors the provisions of the Indian Child Welfare Act, 25 U.S.C. § 1913. The Guidelines of the Bureau of Indian Affairs provide additional guidance as follows:
"A consent to termination of parental rights or adoption may be withdrawn by the parent at any time prior to entry of a final decree of voluntary termination or adoption by filing an instrument executed under oath by the parent stipulating his or her intention to withdraw such consent. The clerk of court where the withdrawal of consent is filed shall promptly notify the party or agency by or through whom the adoptive placement has been arranged of such filing and that party or agency shall insure the return of the child to the parent as soon as practicable." The Commentary to the guideline further provides that "This provision recommends that the clerk of court be responsible for notifying the family with whom the child has been placed that consent has been withdrawn. The court's involvement frequently may be necessary [because] the biological parents are often not told who the adoptive parents are."
