Under Missouri fence law, neighbors who share a property boundary are generally expected to split the fence between them, with each side maintaining the portion that falls to their right when standing at the middle of the line and facing the fence. How much your neighbor actually has to pay, and what happens when livestock get loose, depends on whether your county follows the general fence law or the local option system set out in Chapter 272 of the Missouri Revised Statutes.
What Counts as a Lawful Fence
A lawful fence in Missouri must be built of posts and wire or boards, stand at least four feet high, and be either mutually agreed on by the neighboring landowners or approved by the associate circuit court of the county. Posts have to be set firmly in the ground no more than twelve feet apart, and the wire or boards must be fastened securely enough to contain horses, cattle, and similar livestock.1Missouri Revisor of Statutes. Missouri Revised Statutes RSMo Section 272.020 – Fencing Requirements
The statute does not name electric fence systems or high-tensile wire. Whether that kind of setup qualifies as a lawful fence generally comes down to whether both neighbors agree on it or a court approves it.
The Right-Hand Rule for Dividing a Shared Fence
Missouri uses the right-hand rule to split responsibility for a division fence. Each landowner maintains the portion that falls to their right when they stand at the center of the common property line on their own land, facing the fence.2Missouri Revisor of Statutes. Missouri Revised Statutes RSMo Section 272.060 – Division Fences, Rights of Parties in, How Determined The result is roughly a fifty-fifty split, with each side owning a specific stretch to build and keep up.
If you and your neighbor cannot agree on who handles what, either of you can apply to the associate circuit judge. The judge sends three disinterested residents from the area to inspect the property and assign each person’s share in writing.2Missouri Revisor of Statutes. Missouri Revised Statutes RSMo Section 272.060 – Division Fences, Rights of Parties in, How Determined
You are also allowed to agree on a different split. That agreement has to be in writing, signed by both parties, and recorded with the county recorder of deeds. Once recorded, it binds not just the two of you but also future owners of both properties.2Missouri Revisor of Statutes.

General Law Counties Versus Local Option Counties
Missouri does not use one uniform fence rule statewide. Counties operate under either the general fence law (the default) or the local option fence law, which a county adopts by citizen vote. Twenty counties currently follow the local option system: Bates, Caldwell, Cedar, Clinton, Daviess, Gentry, Grundy, Harrison, Knox, Linn, Macon, Mercer, Newton, Putnam, St. Clair, Schuyler, Scotland, Shelby, Sullivan, and Worth. Every other county uses the general fence law. The system that governs your county changes the answer to two questions: who pays for the fence, and who is on the hook when livestock get out.
Who Pays for the Fence
Under the general fence law, a landowner who does not keep livestock is not required to share the cost of building or maintaining a division fence. The neighbor who needs the fence pays for the whole thing.3Missouri Revisor of Statutes. Missouri Revised Statutes RSMo Section 272.132 – Total Cost of Fence Attributable to One Landowner, When If that non-livestock neighbor later puts animals against the fence, they owe the original builder half the construction cost.
In local option counties, cost sharing is mandatory even if you do not own a single animal. Both landowners contribute equally. If your neighbor asks for a fence and you ignore the request for ninety days, that neighbor can apply to the associate circuit court for an order allowing them to build the whole thing and bill you for half, though your share cannot exceed the cost of a standard four-barbed-wire lawful fence.4Missouri Revisor of Statutes. Missouri Revised Statutes RSMo Section 272.240 – Partition Fences, Owner May Demand Payment, When Court costs are charged to the landowner who ignored the request.
Who Is Liable When Livestock Escape
Under the general fence law, a livestock owner whose animals break through a lawful fence is liable for damages only if the owner was negligent.5Missouri Revisor of Statutes. Missouri Revised Statutes RSMo Section 272.030 – Owners of Stock Liable for Damages, When If the animals escaped through a stretch of fence the injured neighbor was supposed to maintain and failed to keep up, the livestock owner generally is not liable for the resulting damage.
In local option counties the framework is similar, but the statute also lets the injured neighbor have the livestock owner’s defective stretch of fence repaired at that owner’s expense when the owner neglects or refuses to fix it. The local option system leans harder on keeping livestock owners responsible for containment.
When Your Neighbor Does Not Want a Fence
In a general-law county, you may own livestock while your neighbor sees no reason to help pay for a boundary fence. Under Section 272.132, you can build the whole fence yourself and report the total cost to the associate circuit judge, who will authorize the cost to be recorded on each deed.3Missouri Revisor of Statutes. Missouri Revised Statutes RSMo Section 272.132 – Total Cost of Fence Attributable to One Landowner, When Recording the cost matters. If your neighbor later starts keeping animals against the fence, the recorded figure is what you use to collect half the construction costs.
Both neighbors can also agree that no fence is needed at all. Section 272.134 makes clear that nothing in Chapter 272 stops adjoining landowners from reaching that understanding.6Missouri Revisor of Statutes. Missouri Revised Statutes RSMo Section 272.134 – Agreement for No Fence Permitted Put it in writing and record it with the county. A handshake will not bind the next owner.
Written Notice Before You Build or Repair
You cannot skip ahead to building or repairing a fence and then demand your neighbor pay half. Missouri law requires written notice first, and the timeline depends on your county’s system.
In general-law counties, a landowner who wants to build or repair a division fence must give written notice to the adjoining landowner before starting work.2Missouri Revisor of Statutes. Missouri Revised Statutes RSMo Section 272.060 – Division Fences, Rights of Parties in, How Determined If the neighbor does not respond or refuses to cooperate, you can repair their portion at their expense after a reasonable time. The statute does not put a specific number of days on “reasonable time,” so document everything in writing in case a judge has to sort it out later.
In local option counties, the timeline is concrete: you have to wait ninety days after giving written notice before you can apply to the associate circuit court for permission to proceed.4Missouri Revisor of Statutes. Missouri Revised Statutes RSMo Section 272.240 – Partition Fences, Owner May Demand Payment, When Jumping the gun can cost you the right to recover half the expense.
How Fence Disputes Get Resolved
Fence disputes run through the associate circuit court, not township trustees or a local government office. When a landowner files a complaint about a trespassing livestock situation or a fence disagreement, the associate circuit judge issues an order appointing three disinterested residents from the area who are not related to either party.7Missouri Revisor of Statutes. Missouri Revised Statutes Section 272.040 – Judge May Appoint Viewers to View Fence These fence viewers inspect the fence, take notes, and testify in court, and their evidence determines whether the fence qualifies as lawful. The statute directs the judge to act “without delay.”
Either party can seek review of the outcome in circuit court the same way as any other civil case.8Justia Law. Missouri Revised Statutes Chapter 272 – Fences and Enclosures In practice, most fence disputes settle once a judge is involved.
Double Damages for Neglecting Your Share
The biggest penalty in Missouri fence law hits landowners who neglect their portion of a division fence. Section 272.110 imposes double damages on any owner who fails to keep their share in good repair or, if the fence is a hedge, fails to trim it at least once a year to no more than four and a half feet high and three feet wide.9Missouri Revisor of Statutes. Missouri Revised Statutes RSMo Section 272.110 – Division Fences to Be Kept in Repair A five-thousand-dollar crop loss becomes a ten-thousand-dollar judgment.
On top of the double-damages penalty, the injured neighbor has the right to repair the neglected portion at the failing owner’s expense and then restrain any livestock that break through because of the disrepair.9Missouri Revisor of Statutes. Missouri Revised Statutes RSMo Section 272.110 – Division Fences to Be Kept in Repair The associate circuit court can also apportion construction or repair costs between neighbors and issue orders compelling compliance. Ignoring a court order pulls contempt proceedings into the picture.
If Your Property Is Inside City Limits
Chapter 272 was written with agricultural land and livestock in mind. Within city limits, local ordinances typically add their own layer of fence regulations, and those can be stricter or simply different: bans on barbed wire in residential zones, prohibitions on electrified fences outside agricultural districts, height limits that differ from the state’s four-foot standard, and setbacks near streets or intersections.
Check your city code before assuming Chapter 272 is the only rulebook that applies. A fence that is perfectly lawful under state statute can still violate a local ordinance, and city code enforcement does not defer to state agricultural law. Landowners in rural unincorporated areas generally only need to work with Chapter 272 itself.
