The District Judge may permit the temporary removal hearing or the adjudicatory hearing to go forward when the non-custodial parent has not been served in accordance with FCRPP 18(1) if it is established on the record that the petitioner has made diligent efforts to serve all other parties, including initiating contact with the child support division of the County Attorney's Office, in an attempt to locate any absent parent. The petitioner shall make continuing diligent efforts after the hearing to locate and notify all persons who were not served.
