Okla. Stat. tit. 58, § 58-185: Release, application by surety for - Issuance and service

of citation.

When a surety of any executor, administrator or guardian desires

to be released from responsibility on account of future acts, he may

make application by petition to the judge of the district court for

relief. The judge must issue a citation to the executor,

administrator, or guardian, to be served personally upon him

requiring him to appear at a time and place, to be therein

specified, and give other security. If he has absconded, left or

removed from the state, or cannot be found after due diligence and

inquiry, service may be made as provided when the citation is to

require further security.
