Okla. Stat. tit. 58 § 384
When it appears to the court that there is good cause although the assets of the estate in personalty are sufficient to satisfy all obligations of the estate or that the estate is insolvent, or that it will require a sale of all the property of the estate of every character, chargeable therewith, to pay the family allowance, expenses of administration and debts, there need be but one petition filed, but one order of sale made and but one sale had, except in case of property, which may be sold as provided in Section 387 of this title. The district court, when a petition for the sale of any property, for any of the purposes herein named, is presented, must inquire fully into the probable amount required to make all such payments, and if there be no more estate chargeable therewith than sufficient to pay the same, may require but one proceeding for the sale of the entire available estate. In such case the petition must set forth all the facts required by Section 412 of this title. When the sale is sought, although assets of the estate in personalty are sufficient to satisfy all obligations of the estate, the court may allow the sale if satisfied that it is in the best interest of the estate.
