Okla. Stat. tit. 58, § 58-314: Additional allowance for maintenance during settlement of

estate.

If the amount set apart as aforesaid be less than that allowed,

and insufficient for the support of the surviving spouse and

children, or either, or, if there be no such personal property to be

set apart, and if there be other estate of the decedent, the court

may in its discretion make such reasonable allowance out of the

estate as shall be necessary for the maintenance of the family,

according to their circumstances during the progress of the

settlement of the estate, which, in case of an insolvent estate,

must not be longer than one (1) year after granting letters

testamentary, or of administration.
