A. When a biological parent, legal guardian, or other person exercising custodial control cannot be located in a juvenile case it shall be sufficient that a person authorized to serve a summons on the individual serves the absent parent, guardian, or other custodial person's nearest known adult relative pursuant to KRS 620.070(2) or by constructive service through a warning order attorney as authorized by the CR 4.07.

B. The 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 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.
