(a) When a child asks to continue or to reenter foster care after age 18 under section 260C.451, the child and the responsible social services agency may enter into a voluntary agreement for the child to be in foster care under the terms of section 260C.451. The voluntary agreement must be in writing and on a form prescribed by the commissioner.
(b) When the child is in foster care pursuant to a voluntary foster care agreement between the agency and the child, and the child is not already under court jurisdiction pursuant to section 260C.193, subdivision 6, the agency responsible for the child's placement in foster care shall:
(1) file a motion to reopen the juvenile protection matter where the court previously had jurisdiction over the child within 30 days of the child and the agency executing the voluntary placement agreement under paragraph (a) and ask the court to review the child's placement in foster care and find that the placement is in the best interests of the child; and
(2) file the out-of-home placement plan required under subdivision 1 with the motion to reopen jurisdiction.
(c) The court shall conduct a hearing on the matter within 30 days of the agency's motion to reopen the matter and, if the court finds that placement is in the best interests of the child, shall conduct the review for the purpose and with the content required under section 260C.203 at least every 12 months as long as the child continues in foster care.
