Wis. Stat. § 815.20
A defendant who has moved to Michigan intending to stay there lost his Wisconsin homestead exemption. He cannot have an exemption in 2 states. Plan Credit Corp. v. Swinging Singles, Inc. 54 Wis. 2d 146, 194 N.W.2d 822 (1972). A vendee in a land contract has an interest sufficient to sustain a homestead exemption. The holder of a judgment lien is subject to a mortgage dated after the judgment. A homestead exemption does not depend on a formal claim to it. Occupancy at the time a lien attaches is sufficient. Lueptow v. Guptill, 56 Wis. 2d 396, 202 N.W.2d 255 (1972). Rental income from a rented portion of a homestead is exempt under the homestead exemption. Schwanz v. Teper, 66 Wis. 2d 157, 223 N.W.2d 896 (1974). Property purchased by a debtor subsequent to the docketing of a judgment and immediately occupied as a homestead becomes exempt to the extent of the statutory protection. Northern State Bank v. Toal, 69 Wis. 2d 50, 230 N.W.2d 153 (1975). The homestead exemption may arise in a partition action. Reckner v. Reckner, 105 Wis. 2d 425, 314 N.W.2d 159 (Ct. App. 1981). Homestead rights are no greater than the underlying property rights when those property rights have been limited by the owners themselves. Master Lock Credit Union v. Rayford, 119 Wis. 2d 301, 349 N.W.2d 737 (Ct. App. 1984). Owners who permanently remove themselves from a home that is for sale with the intent of using the proceeds to procure another home are entitled to a homestead exemption in the sale proceeds. Moore v. Krueger, 179 Wis. 2d 449, 507 N.W.2d 155 (Ct. App. 1993). Because a judgment lien was subject to the homestead exemption while a federal tax lien was not, the operation of the homestead exemption effectively subordinated the otherwise superior judgment lien to the status of a junior lien, which was discharged by operation of federal law by the execution of the IRS's quitclaim deed after judicial sale. CVW, Ltd. v. Stress, 230 Wis. 2d 450, 602 N.W.2d 162 (Ct. App. 1999), 99-0252. When equity in a homestead exceeds $40,000, the homestead is partially exempt, and a docketed judgment is a lien upon the debtor's equity in excess of the $40,000. If a debtor has less than $40,000 in equity, the homestead is fully exempt, and the debtor has no interest to which a judgment lien may attach. Accordingly a debtor-seller can give clear title to the purchaser of fully exempt property. Rumage v. Gullberg, 2000 WI 53, 235 Wis. 2d 279, 611 N.W.2d 458, 98-1276. An in-court oral stipulation could create a mortgage interest in property, but under s. 706.02(1) (f), a homestead conveyance must bear the conveyor's signatures. Because the stipulation lacked signatures, it was not a mortgage that could defeat the homestead exemption under sub. (1). Equitable Bank, S.S.B. v. Chabron, 2000 WI App 210, 238 Wis. 2d 708, 618 N.W.2d 262, 99-2639. A homestead created and maintained with stolen or embezzled property, or by the wrongful appropriation of property rightly belonging to others, is not protected by the homestead exemption. Estate of Paulman v. Pemberton, 2001 WI App 164, 246 Wis. 2d 909, 633 N.W.2d 715, 98-3021. Although debts were contracted prior to the effective date of an increase in the homestead exemption, the debtors were entitled to higher the exemption. Matter of Zahn, 605 F. 2d 323 (1979). The homestead exemption is void under the supremacy clause of the U.S. constitution to the extent that it impedes a federal court restitution order. U.S. v. Lampier, 89 F.3d 1316 (1996). Establishment and abandonment of a Wisconsin homestead. Kreitler, 1973 WLR 876.
