Okla. Stat. tit. 10, § 10-7700-623: Admission of paternity

A. A respondent in a proceeding to adjudicate parentage may

admit to the paternity of a child by filing a pleading to that

effect or by admitting paternity under penalty of perjury when

making an appearance or during a hearing.

B. If the court finds that the admission of paternity satisfies

the requirements of this section and finds that there is no reason

to question the admission, the court shall issue an order

adjudicating the child to be the child of the man admitting

paternity.
