Okla. Stat. tit. 20 § 106.6
The presiding judge may assign a court reporter to serve anywhere within the administrative district in which the court reporter is appointed. A court reporter shall be paid travel expenses incurred in connection with his official duties outside the county wherein he resides. No expenses shall be paid by the state to a court reporter for travel in his county of residence. Expense vouchers shall be submitted to the Supreme Court for approval. The expense vouchers or claims submitted to the Supreme Court shall have endorsed thereon the signed approval of the presiding judge of the district in which the court reporter incurred the expense for which claim is made.
The Supreme Court may, with the consent of the presiding judge of his district, assign a court reporter to temporary service outside his own administrative district. A court reporter shall be paid travel expenses incurred in connection with his official duties during such periods of temporary assignment. Whenever a court reporter is assigned to serve a district court outside his judicial administrative district, he shall submit a claim for his mileage, subsistence expense or per diem, as the case may be, to the court clerk in the county where he is assigned to serve and the claim, at the rate authorized by the state, shall, upon its approval by the chief judge, be paid by check or warrant drawn against the court fund.
