Okla. Stat. tit. 58, § 211

When there is delay in granting letters testamentary, or of administration, from any cause, or when such letters are granted irregularly, or no sufficient bond is filed as required, or when no application is made for such letters, or when an administrator or executor dies, or is suspended, suspended partially, or removed, the judge of the district court may appoint a special administrator to collect and take charge of the estate of the decedent, in whatever county or counties the same may be found, and to exercise such other powers as may be necessary for the preservation of the estate.
