Okla. Stat. tit. 20, § 20-95.1: Places of holding district court

A. Unless and until the Supreme Court or the presiding judge of

the judicial administrative district provides otherwise, and

excluding any business courts established pursuant to Section 91.7

of this title, the district court shall hold court in the county

seat of every county in the district, in any city where a superior

court held sessions and at such other places within the district as

the district and associate district judges shall prescribe.

B. If a governing board of the court fund receives a request

from a municipality that court be held within that municipality and

the board determines that sufficient reasons exist for establishing

a court and that sufficient funds and space for a court are made

available by the municipality, the board may establish a court,

presided over by a special judge, in that municipality. The request

to hold court in a municipality shall be included in the budget

submitted by the governing board of the court fund to the Chief

Justice of the Supreme Court and approved by the Chief Justice.
