Okla. Stat. tit. 58, § 58-412: Application for sale of realty

To obtain an order for the sale of real property, the executor

or administrator must present a verified application to the court

setting forth that the sale of the real property will be in the best

interest of the estate and a general description of all the real

property except the homestead of which the decedent died seized, or

in which he had any interest, or in which the estate has acquired

any interest, and the value thereof; the names of the heirs,

legatees and devisees of the decedent, if any, so far as known to

the petitioner. If any of the matters here enumerated cannot be

ascertained, it must be so stated in the application; but a failure

to set forth the facts showing the sale to be supported by good

cause will not invalidate the subsequent proceedings, if the defect

be supplied by the proofs at the hearing, and the general facts

showing such good cause be stated in the decree.
