The court, when it finds the respondent has failed to perform the order of the court concerning the custody or the maintenance and support of the child or support and maintenance of the spouse, or under the existing circumstances is under the duty to render support or additional support to the child or to pay for the support and maintenance of the spouse, may proceed to deal with the respondent as provided in §§ 20-79.1, 20-114, and 20-115. In addition, the court may enter a qualified domestic relations order or other order for the purpose of enforcing a support order by attaching or garnishing any pension, profit-sharing, or deferred compensation plan or retirement benefits pursuant to the United States Internal Revenue Code or other applicable federal laws. The court may revise and alter its decree as to the child or support and maintenance of the spouse, and grant leave to the petitioner to proceed in the appropriate juvenile and domestic relations district court in conformity with any applicable law; or it may, at the application of any party or on its own motion certify its final order granting support of the child or support and maintenance of the spouse to such juvenile and domestic relations district court for enforcement of collection as though such order had been made in such juvenile and domestic relations district court, in accordance with § 20-79 (c). When the petitioner has been granted leave to proceed in a juvenile and domestic relations district court all proceedings thereafter shall conform to the provisions of Chapter 5 (§ 20-61 et seq.).
