Okla. Stat. tit. 23, § 23-27: Breach of agreement to convey

The detriment caused by the breach of an agreement to convey an

estate in real property, is deemed to be the price paid and the

expenses properly incurred in examining the title and preparing the

necessary papers, with interest thereon; but adding thereto, in case

of bad faith, the difference between the price agreed to be paid,

and the value of the estate agreed to be conveyed, at the time of

the breach, and the expenses properly incurred in preparing to enter

upon the land.
