Okla. Stat. tit. 58, § 58-344: Partial allowance of claim

Whenever any claim is presented to an executor or administrator,

or to the judge of the district court, and he is willing to allow

the same in part, he must state in his endorsement the amount he is

willing to allow. If the creditor refuse to accept the amount

allowed in satisfaction of his claim, he shall recover no costs in

an action therefor, brought against the executor or administrator,

unless he recovers a greater amount than that offered to be allowed.
