Okla. Stat. tit. 10, § 10-7700-637

A. Except as otherwise provided in subsection B of this

section, a determination of parentage is binding on:

1. All signatories to an acknowledgment or denial of paternity

as provided in Article 3 of the Uniform Parentage Act; and

2. All parties to an adjudication by a court acting under

circumstances that satisfy the jurisdictional requirements of

Section 601-201 of Title 43 of the Oklahoma Statutes.

B. A child is not bound by a determination of parentage under

the Uniform Parentage Act unless:

1. The determination was based on an unrescinded acknowledgment

of paternity and the acknowledgment is consistent with the results

of genetic testing;

2. The adjudication of parentage was based on a finding

consistent with the results of genetic testing and the consistency

is declared in the determination or is otherwise shown; or

3. The child was a party or was represented in the proceeding

determining parentage by an attorney or guardian ad litem.

C. In a proceeding to dissolve a marriage, the court is deemed

to have made an adjudication of the parentage of a child if the

court acts under circumstances that satisfy the jurisdictional

requirements of Section 601-201 of Title 43 of the Oklahoma Statutes

and the final order:

1. Expressly identifies a child as a “child of the marriage”,

“issue of the marriage”, or similar words indicating that the

husband is the father of the child; or

2. Provides for support of the child by the husband unless

paternity is specifically disclaimed in the order.

D. Except as otherwise provided in subsection B of this

section, a determination of parentage may be a defense in a

subsequent proceeding seeking to adjudicate parentage by an

individual who was not a party to the earlier proceeding.

E. A party to an adjudication of paternity may challenge the

adjudication only under law of this state relating to appeal,

vacation of judgments, or other judicial review.
