Okla. Stat. tit. 12, § 12-774: Reversal of judgment after sale of land

If any judgment or judgments, in satisfaction of which any lands

or tenements are sold, shall at any time thereafter be reversed,

such reversal shall not defeat or affect the title of the purchaser

or purchasers; but in such cases, restitution shall be made, by the

judgment creditors, of the money, for which such lands or tenements

were sold, with lawful interest from the day of sale.
