Okla. Stat. tit. 58, § 58-336: Claim by district judge - Proceedings

The judge of the district court may present a claim against the

estate of a decedent, for allowance, to the executor or

administrator thereof; and if the executor or administrator allows

or rejects the claim, he must, in writing, present the same to the

county clerk of the county, who shall thereupon be substituted in

the settlement of said estate in place of the judge of the district

court, as provided by law, and the judge of the district court

presenting such claim, in case of its rejection by the executor or

administrator, or by such county clerk, acting as judge, has the

same right to sue in a proper court for its recovery as other

persons have when their claims against an estate are rejected.
