Wisconsin Chapter 90 Fence Law: Who Pays for Agricultural and Boundary Fences?

Sharing a property line in Wisconsin often means sharing the responsibility for the fence that divides it. However, fence disputes are one of the most common sources of conflict between neighbors. Whether you are running a dairy farm in Dane County or managing a hobby farm in Outagamie County, understanding your legal obligations regarding boundary fences is essential to protecting your property and your wallet.

In Wisconsin, fence disputes are heavily governed by state statutes rather than just local unwritten rules. The law distinguishes clearly between rural farming properties and suburban residential lots. If your neighbor is refusing to pay their fair share to fix a rotting partition fence, this guide will explain your rights under Wisconsin Chapter 90 and outline the exact steps to legally force compliance.

The "Equal Shares" Rule for Agricultural Fences

The foundation of Wisconsin's fence law is found in Wis. Stat. § 90.03, which establishes the "equal shares" rule. This statute mandates that the owners of adjoining lands used for farming or grazing must maintain partition fences in equal shares. This means that if a fence needs to be built or repaired to keep livestock in (or out), both neighbors are legally responsible for 50% of the cost and labor, even if only one neighbor actually owns livestock.

The law is designed to promote agricultural harmony. A "legal fence" is explicitly defined in Wis. Stat. § 90.02, which details acceptable materials, such as woven wire, barbed wire, or high-tensile wire, and specific height requirements. If you build a fence that meets these statutory requirements, your agricultural neighbor is obligated to share the burden.

Farming Communities vs. Residential Zoning

A frequent point of confusion is whether Chapter 90 applies to residential neighborhoods. Generally, the strict mandatory cost-sharing rules of Chapter 90 do not apply to standard suburban or city subdivisions. The law specifically targets lands where at least one parcel is used for farming or grazing. If you live in a residential neighborhood in Milwaukee or a subdivision in Waukesha, you cannot simply build a privacy fence and send your neighbor half the bill under Chapter 90. In residential areas, fence costs are typically governed by private agreements or local municipal zoning codes.

What to Do When a Neighbor Refuses to Pay

When an agricultural neighbor flat-out refuses to repair their half of the fence or pay their share, Wisconsin law provides a unique and historical remedy: calling the "Fence Viewers." You do not have to immediately rush to the local courthouse and file an expensive lawsuit.

Calling the Fence Viewers (Town Supervisors)

Under Wis. Stat. § 90.01, the town supervisors in your local municipality automatically act as the official "Fence Viewers." If there is a dispute, you can formally request that the Fence Viewers come to the property line. For example, if you live in Verona, you would contact the Town of Verona Board of Supervisors, Verona.

The Fence Viewers will physically inspect the boundary, listen to both sides, and issue a written binding decision. They will determine which portion of the fence each neighbor is responsible for building or repairing. They can also dictate a specific timeline (usually 30 days) for the work to be completed.

Enforcing the Fence Viewer's Order

If your neighbor ignores the written order from the Fence Viewers, the law empowers you to take action. Under Wis. Stat. § 90.11, you are legally permitted to build or repair the neighbor's assigned portion of the fence yourself. Once the work is done, the Fence Viewers will inspect it and issue a certificate specifying the actual expense of the work along with their fees.

You do not need to file a small claims lawsuit to get paid. In Tomaszewski v. Giera, 260 Wis. 2d 569 (WI Court of Appeals 2003), the Wisconsin Court of Appeals confirmed that the administrative remedy in Wis. Stat. § 90.11 is the exclusive remedy for recovering these expenses. You first demand the certified amount and fees from the neighbor. If they fail to pay within one month, the amount accrues interest at 1% per month under Wis. Stat. § 90.11(1)(c). Under Wis. Stat. § 90.11(2), you then file the certificate with the town clerk (such as the Town of Verona, Verona). The town treasurer pays you the certified amount directly from the town treasury, and the municipality places that sum, plus interest, as a special charge and tax lien against the delinquent neighbor's property. Unlike viewer compensation disputes under Wis. Stat. § 90.15, which allow viewers to recover double their unpaid fees, landowners can only recover the actual repair costs and statutory interest.
