Any person entitled to receive support payments either personally or on behalf of another person, by reason of any support order that does not direct that payments be made to the office of child support, may apply to the appropriate child support enforcement agency for the administration of the order. On receipt of the application, the agency has authority to administer the order. The agency shall notify the obligor by any method of service authorized under the Civil Rules to make all support payments due after service of the notice on the obligor to the office. An obligor so notified by an agency shall make all subsequent payments to the office unless the court, on the obligor’s application filed within thirty days after service of the notice on the obligor, orders the child support enforcement agency not to administer the support order.
