Okla. Stat. tit. 58 § 596
Subject to the provisions of Section 5 of Title 46 of the Oklahoma Statutes, if there is any claim not due, or any contingent or disputed claim against the estate, the court may direct that the amount thereof, or such part of the same as the holder would be entitled to if the claim were due, established or absolute, be paid into the court, and there remain, to be paid over to the party when he becomes entitled thereto, or the court may direct that such claim be satisfied in some other manner as determined by the court in its discretion; or, if the party fails to establish his claim, to be paid over or distributed as the circumstances of the estate require. If any creditor whose claim has been allowed, but is not yet due, appears and assents to a deduction therefrom of the legal interest for the time the claim has yet to run, he is entitled to be paid accordingly. The payments provided for in this section are not to be made when the estate is insolvent, unless a pro rata distribution is ordered.
