§10-7505-4.3.
   
   A. If, at any time in a proceeding for adoption or for termination of
   a relationship of parent and child pursuant to the Oklahoma Adoption
   Code, the court finds that an unknown father or putative father of the
   child may not have received notice, the court shall determine whether
   he can be identified. The determination must be based on evidence that
   includes inquiry of appropriate persons in an effort to identify an
   unknown father or putative father for the purpose of providing notice.
   
   B. The inquiry required by subsection A of this section must include
   whether:
   
   1. The woman who gave birth to the child was married at the probable
   time of conception of the child, or at a later time;
   
   2. The woman was cohabiting with a man at the probable time of
   conception of the child;
   
   3. The woman has received payments or promises of support, other than
   from a governmental agency, with respect to the child or because of
   her pregnancy;
   
   4. The woman has named any individual as the father on the birth
   certificate of the child or in connection with applying for or
   receiving public assistance; and
   
   5. Any individual has formally or informally acknowledged or claimed
   paternity of the child in a jurisdiction in which the woman resided
   during or since her pregnancy, or in which the child has resided or
   resides, at the time of the inquiry.
   
   C. If inquiry pursuant to subsection B of this section identifies as
   the father or putative father of the child an individual who has not
   received notice of the proceeding, the court shall require notice to
   be served upon him pursuant to Section 7505-2.1 or 7505-4.1 of this
   title.
   
   D. If, in an inquiry pursuant to this section, the woman who gave
   birth to the child fails to disclose the identity of a possible father
   or reveal his whereabouts, she must be advised that the lack of
   information about the father's medical and genetic history may be
   detrimental to the child. She should also be advised that any false
   statement that she might make under oath or affirmation at a hearing
   or trial before the court regarding her knowledge of the identity or
   whereabouts of a possible father, if she knows or believes that the
   statement is not true or intends thereby to obstruct the ascertainment
   of the truth, could constitute grounds for a criminal prosecution for
   perjury.
