Wisconsin Adverse Possession Law: What It Means for Your Property

By Attorney Attorney Jack W. Rettler, Schloemer Law Firm, S.C.

Under Wisconsin law, a trespasser can sometimes gain legal ownership to land by occupying it under a doctrine called ‘adverse possession’ if certain elements are met.  For example, if a neighbor places a fence or building over a property line or farms over a property line, and this practice continues for over 20 years and other requirements are met, the neighbor can end up owning that part of your property that they have been using.

The physical character of the possession is key—and the use of the land must be open, notorious, visible, exclusive, hostile and continuous, such as would apprise a reasonably diligent landowner and the public that the possessor claims the land as his own.

The adverse possession must be sufficiently open and obvious to have apprised the title holder of both the fact of the possession and the intent to exclude others from possession.

It’s important to understand how the above terms have been defined through case law.  Below is a summary of the various elements of adverse possession as described in the Wisconsin Jury Instructions:

“Hostile” does not mean a deliberate, willful, or unfriendly intent.  If the characteristics of open, notorious, exclusive, and continuous possession are satisfied, the law presumes the element of hostile intent.  “Hostile” means that the person in actual possession of the land claims exclusive right to it.

Land is “actually occupied” when it is used in a way it is ordinarily capable of being used and in such a manner as an owner would use it.  Actual occupation is not limited to structural encroachment, although that it is a common physical characteristic of possession.

The requirement of “substantial enclosure” must alert a reasonable person of a dispute over the land.  “Usually cultivated or improved” means the one in possession has put the land to the same kind of use that a title holder might generally put the land.

The title holder will always be presumed to be in possession of the land claimed by the adverse possessor.  Thus, the burden is on the adverse possessor to establish the claim.

Finally, the adverse possessor has the burden of proof to clearly define the area of land claimed to be adversely possessed.  While absolute precision or utilization of a surveyor is not required to establish lines of occupancy, the evidence must provide a reasonably accurate basis upon which to determine the boundary of the land adversely possessed.
