Summary
Wisconsin's partition fence statute (WI Stat 90.03) requires adjoining rural/agricultural landowners to share cost of boundary fences. In urban Madison, the line fence statute rarely applies; disputes are civil matters.
90.02 Legal fences; space between ground and bottom. (1) In this section, "high tensile wire" means wire with a tensile strength of 1,235 to 1,450 mega pascals or 179,000 to 210,000 pounds per square inch. (1m) The following and none other are legal and sufficient fences: (a) A fence of strong woven wire not less than 26 inches wide with 3 barbed wires or 3 high tensile wires above. (b) A fence of strong woven wire not less than 30 inches wide with 2 barbed wires or 2 high tensile wires above.

[...] (3) Fences shall not be less than 50 inches high, and the bottom of the fence shall be not more than 4 inches from the ground, measurements to be made at the posts. 90.03 Partition fences; when required. The respective occupants of adjoining lands used and occupied for farming or grazing purposes, and the respective owners of adjoining lands when the lands of one of such owners is used and occupied for farming or grazing purposes, shall keep and maintain partition fences between their own and the adjoining premises in equal shares so long as either party continues to so occupy the lands, except that the occupants of the lands may agree to the use of markers instead of fences, and such fences shall be kept in good repair throughout the year unless the occupants of the lands on both sides otherwise mutually agree.
Full Breakdown
WI Stat Chapter 90 is Wisconsin's historic line fence (partition fence) law. It requires adjoining landowners of agricultural or rural parcels to share the cost of boundary fences equitably, with town supervisors empowered to adjudicate disputes (WI Stat 90.03 and 90.05). Within Madison city limits, the vast majority of parcels are urban residential and the partition fence statute does not apply directly. City ordinances do not force neighbors to share fence costs. Fences must be installed on or inside your own property line; straddling the line requires a written agreement. The good side of the fence generally must face the neighbor. Disputes over fence location, maintenance, damage, or encroachment are civil matters handled through small claims court or private mediation. Dane County Extension and mediation services can help. A survey is strongly recommended before installing a line fence to avoid encroachment claims.
