An affidavit setting forth diligent efforts to locate a known birth father must accompany any complaint to allow service by publication. The affidavit typically indicates that diligent inquiries have been made at the birth father's last known address, last known place of employment, attempts made to contact him at all known phone numbers and through all known relatives.
Affidavits also often include language that commonly known databases have been searched to no avail. The Responsible Father Registry took effect in July of 2010 The registry should be contacted as part of a diligent effort to find birth fathers. The Registry should be searched on the day the Complaint For Adoption is filed, but may be searched prior to the date of filing the Complaint for Adoption as well.
