Wyo. Stat. Ann. § 34.1-9-333
(a) In this section, 'possessory lien' means an interest, other than a security interest or an agricultural lien:
(i) 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;
(ii) Which is created by statute or rule of law in favor of the person; and
(iii) Whose effectiveness depends on the person's possession of the goods.
(b) 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.
