Okla. Stat. tit. 58, § 58-594: When certain expenses paid

The executor or administrator, as soon as he has sufficient

funds in his hands, must pay the funeral expenses, and the expenses

of the last sickness, and the allowance made to the family of the

decedent. He may retain in his hands the necessary expenses of

administration, but he is not obliged to pay any other debt or any

legacy until, as prescribed in this chapter, the payment has been

ordered by the court.
