Adjoining landowners are owners of land with common boundaries, and have mutual rights, duties, and obligations related to their adjoining pieces of land.
In Wisconsin, adjoining landowners, also known as adjacent property owners, have certain rights and responsibilities concerning their shared property boundaries. These include maintaining boundary lines, managing shared resources like fences and trees, and addressing any encroachments. Wisconsin's statutes outline specific rules for situations such as the maintenance and construction of partition fences (Wis. Stat. § 90.03), which are fences that divide the properties of different owners. Each owner is typically responsible for the fence lying to the right of their property when facing the dividing line. Additionally, Wisconsin follows the common law rule for tree liability, meaning that if a tree on one person's property falls and damages the adjoining property, the tree owner may be liable if the fall was due to negligence or if the tree was known to be hazardous. Disputes between adjoining landowners can often be resolved through local ordinances or through civil litigation if necessary.
