Section 409.333 - Priority of certain liens arising by operation of law(1) POSSESSORY LIEN. In this section, "possessory lien" means an interest, other than a security interest or an agricultural lien: (a) Which secures payment or performance of an obligation for services or materials furnished with respect to goods by a person in the ordinary course of the person's business;(b) Which is created by statute or rule of law in favor of the person; and(c) Whose effectiveness depends on the person's possession of the goods.(2) PRIORITY OF POSSESSORY LIEN. A possessory lien on goods has priority over a security interest in the goods unless the lien is created by a statute that expressly provides otherwise. A lien under s. 779.43(3) is contingent on possession and is a possessory lien under sub. (1) with priority over a security interest. Premier Community Bank v.
