Okla. Stat. tit. 58, § 58-106: Executor disqualified by absence or minority

Where a person absent from the state, or a minor, is named

executor, and there is another executor who accepts the trust and

qualifies, the latter may have letters testamentary and administer

the estate until the return of the absentee, or the majority of the

minor, who may then be admitted as joint executor. If there is no

other executor, letters of administration with the will annexed,

must be granted; but the court may, in its discretion, revoke them

on the return of the absent executor, or the arrival of the minor at

the age of majority.
