Perfection of security interests in property subject to certain statutes, regulations, and treaties
Wis. Stat. § 409.311
in effect(1) Security interest subject to other law. Except as otherwise provided in sub. (4), the filing of a financing statement is not necessary or effective to perfect a security interest in property subject to:
(a) A statute, regulation, or treaty of the United States whose requirements for a security interest’s obtaining priority over the rights of a lien creditor with respect to the property preempt s. 409.310 (1).
(b) The following vehicle title statutes: ss. 342.19 and 342.20.
(bm) The following boat title statutes: ss. 30.57, 30.572, and 30.573.
(c) A statute of another jurisdiction which provides for a security interest to be indicated on a certificate of title as a condition or result of the security interest’s obtaining priority over the rights of a lien creditor with respect to the property.
(d) Sections 182.025 and 190.11 and other statutes providing for central filing.
(e) A master lease entered into by the state under s. 16.76 (4).
(f) The manufactured home security interest provisions under subch. V of ch. 101.
(2) Compliance with other law. Compliance with the requirements of a statute, regulation, or treaty described in sub. (1) for obtaining priority over the rights of a lien creditor is equivalent to the filing of a financing statement under this chapter. Except as otherwise provided in sub. (4) and ss. 409.313 and 409.316 (4) and (5) for goods covered by a certificate of title, a security interest in property subject to a statute, regulation, or treaty described in sub. (1) may be perfected only by compliance with those requirements, and a security interest so perfected remains perfected notwithstanding a change in the use or transfer of possession of the collateral.
(3) Duration and renewal of perfection. Except as otherwise provided in sub. (4) and s. 409.316 (4) and (5), duration and renewal of perfection of a security interest perfected by compliance with the requirements prescribed by a statute, regulation, or treaty described in sub. (1) are governed by the statute, regulation, or treaty. In other respects, the security interest is subject to this chapter.
(4) Inapplicability to certain inventory. During any period in which collateral subject to a statute specified in sub. (1) (b), (bm), or (f) is inventory held for sale or lease by a person or leased by that person as lessor and that person is in the business of selling goods of that kind, this section does not apply to a security interest in that collateral created by that person.
