If the court terminates the rights of a parent and places the child with an individual or agency, the court may vest in such individual or agency authority to consent to the adoption of the child. Provided, that when the court places the child with the Department of Human Services, it shall vest the Department with authority to place the child and, upon notice to the court that an adoption petition has been filed concerning the child, vest the Department with authority to consent to the adoption of the child, and the jurisdiction of the committing court shall terminate upon a final decree of adoption.
