Okla. Stat. tit. 12, § 2011.1
In any action not arising out of contract, if requested the court shall, upon ruling on a motion to dismiss an action or a motion for summary judgment or subsequent to adjudication on the merits, determine whether a claim or defense asserted in the action by a nonprevailing party was frivolous. As used in this section, "frivolous" means the claim or defense was knowingly asserted in bad faith, was unsupported by any credible evidence, was not grounded in fact, or was unwarranted by existing law or a good faith argument for the extension, modification, or reversal of existing law or the establishment of new law. Upon so finding, the court shall enter an order requiring such nonprevailing party to reimburse the prevailing party for reasonable costs, including attorney fees, incurred with respect to such claim or defense. In addition, the court may impose any sanction authorized by Section 2011 of Title 12 of the Oklahoma Statutes.
