Okla. Stat. tit. 58, § 58-712: Revocation of letters for contumacy

Whenever an executor, administrator, or guardian is committed

for contempt, in disobeying any lawful order of the district court

or the judge thereof, and has remained in custody for thirty (30)

days without obeying such order or purging himself otherwise of the

contempt, the district court may, by order reciting the facts, and

without further showing or notice, revoke his letters and appoint

some other person, entitled thereto, executor, administrator or

guardian in his stead.
