(A) The voluntary written surrender of all parental rights from one of the parents or the guardian of a child; or

(B) An order of a court of competent jurisdiction terminating all of the rights of one of the parents or the guardian of a child,

and the court shall set the matter down to be heard in chambers not less than 30 and not more than 60 days following the receipt by such remaining parent of the notice under subsection (b) of this Code section and shall enter an order terminating such parental rights if it so finds and if it is of the opinion that adoption is in the best interests of the child, after considering the physical, mental, emotional, and moral condition and needs of the child who is the subject of the proceeding, including the need for a secure and stable home.

(b) Whenever a petition is filed pursuant to subsection (a) of this Code section, the parent whose rights the petitioner is seeking to terminate shall be personally served with a conformed copy of the petition, and a copy of the court's order setting forth the date upon which the petition shall be considered or, if personal service cannot be perfected, by registered or certified mail or statutory overnight delivery, return receipt requested, at his last known address.
