Okla. Stat. tit. 58, § 58-383: Petition for orders for sale

All petitions for orders of sale must be in writing, setting

forth the facts showing the sale to be supported by good cause, and

upon the hearing, any person interested in the estate may file his

written objections, which must be heard and determined. 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 good cause be stated in the order directing the sale.
