D. The notice shall state that the person served shall respond to the petition within twenty days if the person intends to contest the adoption and shall state that the failure to so respond shall be treated as a default and the person’s consent to the adoption shall not be required.

Ann. shall investigate the whereabouts of the parent and shall file by affidavit the results of the investigation with the court. Upon a finding by the court that information as to the whereabouts of a parent has been sufficiently investigated and is still insufficient to effect service in accordance with the Rules of Civil Procedure for

the District Courts, the court shall issue an order providing for service by publication.
