(b) If the court identifies a father pursuant to the provisions of subsection (a) of this section, then notice of the proceeding for adoption shall be served on the father so identified in accordance with the provisions of section 22-602.
(c) If after consideration of the affidavit and/or the consideration of further evidence, the court finds that proper service cannot be made upon the father because his identity is unknown, the court shall order publication of the notice only if, on the basis of all information available, the court determines that publication is likely to lead to receipt of notice by the father. If the court determines that publication or posting is not likely to lead to receipt of notice, the court may dispense with the publication or posting of a notice.
