A. Except as otherwise provided by Section 7700-607 of Title 10 of the Oklahoma Statutes, in any action concerning the custody of a minor unmarried child or the determination of child support, the court may determine if the parties to the action are the parents of the children. In a paternity action, prior to genetic testing to establish paternity pursuant to the Uniform Parentage Act, the court may award custody to the presumed father if it would be in the best interests of the child. As used in this subsection, “presumed father” means a man who, by operation of law under Section 7700-204 of Title 10 of the Oklahoma Statutes, is recognized as the father of a child until that status is rebutted or confirmed in a judicial proceeding.

B. If the parties to the action are the parents of the children, the court may determine which party should have custody of said children, may award child support to the parent to whom it awards custody, and may make an appropriate order for payment of costs and attorney fees.
