Okla. Stat. tit. 58, § 389

Partnership interests, or interests belonging to any estate by virtue of any partnership formerly existing, interest in personal property pledged, and choses in action, may be sold in the same manner as other personal property, when it appears to be for the best interest of the estate. Before confirming the sale of any partnership interest, whether made to the surviving partner or to any other person, the judge must carefully inquire into the condition of the partnership affairs, and must examine the surviving partner, if in the county and able to be present in court.
