Sec. 23e. (1) Not later than 14 days after the filing of a petition by the prosecutor as required by section 23d(4) of this chapter,  1 by a prospective adoptive parent as permitted in section 23d(6) of this chapter, or by a child placing agency as required by section 23d(7) of this chapter, the court shall hold a hearing to determine the custody of a child for whom a temporary placement has been made.

(2) Upon receiving a petition filed under section 23d(5) of this chapter, the court shall immediately issue an ex parte order directing the prospective adoptive parent to return the child to the parent or guardian with legal custody within 24 hours after receipt of the order, unless the court proceeds under subsection (3).

(3) The court may appoint an attorney to represent the child or refer the matter to the department.

(6) The court may appoint a guardian ad litem for the child or for a minor parent of the child.

(7) This act provides the exclusive remedy for all custody disputes arising out of a temporary placement.
