Okla. Stat. tit. 12A, § 12A-2A-306: Priority of certain liens arising by operation of law

PRIORITY OF CERTAIN LIENS ARISING BY OPERATION OF LAW

If a person in the ordinary course of his business furnishes

services or materials with respect to goods subject to a lease

contract, a lien upon those goods in the possession of that person

given by statute or rule of law for those materials or services

takes priority over any interest of the lessor or lessee under the

lease contract or this article unless the lien is created by statute

and the statute provides otherwise or unless the lien is created by

rule of law and the rule of law provides otherwise.
