Okla. Stat. tit. 10, § 10-7505-4.3: Inquiry to identify unknown or putative father

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.
