Okla. Stat. tit. 63, § 63-1-315: Judicial proceeding for record of birth

(a) Any citizen of the United States who has resided in this

state for not less than ten (10) years, the last three (3) of which

must have been continuous within this state and the last one (1) of

which must have been continuous within the county of his

application, the birth of whom has not been recorded by the State

Commissioner of Health, or his predecessor, may petition the

district court of the county in which he resides or was born for an

order establishing a public record of the time and place of his

birth and his parentage. He may have the record of such information

entered in the following manner: Such applicant may appear before a

judge of the district court in the county of which he is a resident

and file his verified petition in writing, which petition shall

state the time and place of his birth and his parentage and such

other facts as he deems pertinent; the petition shall be filed in

the office of the court clerk and given a number in the probate

files thereof; thereupon the applicant shall produce all the

evidence he has in his possession, which may consist of personal

testimony, affidavits or records, and shall include a statement from

the State Commissioner of Health, or similar official in the state

of applicant's birth, to the effect that a birth certificate is not

recorded in his office; and if the judge of the district court shall

be satisfied with the proof offered, he shall make and enter an

order establishing the time and place of birth, the age and the

parentage of the applicant, which order shall be final and

conclusive of all the facts therein adjudged.

(b) A certified copy of the order shall be filed in the office

of the State Commissioner of Health, and a certified copy thereof

shall be issued by the Commissioner in the same manner as

certificates of birth.
