Texas Fence Laws for Ranchers: Open Range, Lawful Fence, and Who Actually Pays for the Fence Between Two Neighbors

The fence law your neighbor's lawyer cites is probably the wrong one. Most "Texas fence law" articles online are written for suburban homeowners arguing about a back-yard cedar fence. They confidently quote a six-foot height limit, a "good neighbor" rule, and a permit requirement that none of them actually applies to a rancher building a 5-strand barbed-wire perimeter on 800 acres in Brown County.

Texas livestock fence law is its own body of statute, written before electricity, refined over 150 years of cattle drives and range wars, and still in force today. This guide covers what actually applies when you're building a fence around livestock in Texas: the open-range vs closed-range county question, what counts as a "lawful fence" under the Agriculture Code, who's responsible for the fence between two neighboring ranches, and where the modern fence systems (high-tensile electric, polybraid, energizers) fit into a body of law that was written for barbed wire.

If you're building a fence in Texas and want to know what the law actually requires, this is the right page. If you're a homeowner dealing with a backyard property-line dispute, this isn't your guide — search "Texas residential fence laws" instead.

The foundation: Texas is a closed-range state — with exceptions

This is the single most important fact to get right, and the one most "Texas fence law" articles fumble.

The default rule in Texas is closed range. Under Texas Agriculture Code §143.102, a livestock owner is responsible for keeping their animals contained on their own property. If your cow gets out and damages a neighbor's crop or causes a vehicle accident, you can be civilly liable for the damages and the animal can be impounded.

The historical default — open range — still applies in a handful of counties. Open range means a livestock owner is not required to fence cattle in; instead, a landowner who doesn't want cattle on their property must fence them out. Texas inherited open range from Spanish ranching tradition, and the legal framework persisted statewide through the 1800s. Over the 20th century, county after county passed local-option "stock laws" closing the range to specific livestock types — typically starting with hogs, then cattle.

Today, the vast majority of Texas counties are closed range for cattle. A small number — historically including parts of Hudspeth, Hudspeth-adjacent counties in far West Texas, and pockets in the Trans-Pecos — remain open range for one or more livestock types. The exact list shifts as counties hold local elections.

To find out what your county is: call your county clerk's office. Don't rely on what your neighbor told you, what a 1990 article said, or what AI search results return. Local-option stock law elections happen and the list changes. The county clerk will tell you whether your county is open or closed range for each livestock type.

Why this matters for fence building: If you're in a closed-range county (most ranchers in Texas), the legal duty is on YOU to fence your livestock in. A poorly built fence isn't just a maintenance problem — it's a liability exposure. If you're in an open-range county, the legal duty is on your neighbor to fence them out — but you may still want a real fence for management reasons, and the "lawful fence" requirement below still affects how fence-collision liability gets allocated.

What is a "lawful fence" under Texas law?

When Texas fence statutes use the term "lawful fence," they mean something specific. The definition appears in Texas Agriculture Code §143.028, and it applies in both open-range and closed-range contexts — though for different reasons.

Under §143.028, a fence is a "sufficient fence" (the statute's term, commonly called "lawful fence") if it meets one of these specifications:

• Barbed wire fence: At least 3 wires, with the top wire at least 4 feet above the ground, and posts no more than 30 feet apart (with stays between posts if posts exceed 15 feet apart).
• Board fence: At least 5 feet tall.
• Rail fence: At least 4 feet tall.
• Stone or concrete fence: At least 4 feet tall.
• Hedge fence: A live hedge of substantial growth and sufficient density to constitute an enclosure.

A fence that doesn't meet these specs isn't necessarily illegal, but it isn't a "lawful fence" for purposes of the statute. The distinction matters in liability disputes (see below).

Where modern systems fit: The statute was written in an era of barbed wire. It doesn't explicitly address electric fence, high-tensile smooth wire, polybraid, or net wire. Texas courts and AgriLife Extension publications have generally treated electric fence and modern high-tensile systems as equivalent or superior to traditional barbed wire when they're built to comparable height, strand count, and post spacing. If you're building a 5-strand electrified high-tensile perimeter at 4+ feet of top wire with posts on 30-ft centers (well within the 50-ft spacing high-tensile can support — see our high tensile wire buyer's guide), you're building a fence at least as good as the statutory minimum.

The fence that demonstrably contained livestock when properly built is what counts in practice, but if you want belt-and-suspenders compliance, build to (or exceed) the statutory specs.

Who pays for the fence between two neighbors?

This is the question that ends friendships, and Texas law's answer is uncomfortable but clear: there is no general "good neighbor fence law" in Texas requiring shared cost.

Unlike some states (California, Iowa, and a number of others have statutes splitting partition-fence costs between adjoining landowners), Texas has no statewide statute requiring two neighbors to share the cost of a fence on their common boundary. If your neighbor builds a fence on the property line, you owe them nothing. If you build it, they owe you nothing.

The exceptions are local and limited:

1. Some counties have local partition fence ordinances — typically older, established agricultural counties. These vary widely. Call your county clerk.
2. A neighbor who uses a fence you built may be liable for a share of the cost under certain common-law theories — for example, if they tear down their own fence and rely on yours to contain their cattle. This is fact-specific and contested in court; don't count on collecting without a lawyer.
3. Written agreements between neighbors trump default rules. If you and the neighbor agree in writing to split the cost of a new fence, that agreement is enforceable.

Practical advice: If you're rebuilding a perimeter fence on a boundary line with a neighbor who runs livestock, get the cost-share agreement in writing before any post goes in the ground. A short signed statement saying "Neighbor agrees to pay X% of materials and 50% of labor for the new perimeter fence between Properties A and B" is enforceable and prevents the awkward conversation later.

The "7-year fence law" — what it actually is

There's a common reference to a "7-year fence law" in Texas that means almost the opposite of what most people think.

The reference is to adverse possession (Texas Civil Practice and Remedies Code §16.026), which allows a person who has continuously occupied land for 10 years (not 7 — the "7-year" reference confuses it with other adverse-possession periods that apply to claims under deed) to acquire title to it. A fence in the wrong place — built on what is actually the neighbor's property — can, in some circumstances, become evidence of adverse possession over time.

This is NOT a law that says "fences become permanent after 7 years and you can't move them." It's a doctrine that says "if you treat someone else's land as your own continuously for the statutory period, you may eventually be able to claim title to it."

Practical implication: If you suspect your existing perimeter fence isn't actually on the property line, get a survey done before you rebuild. A new fence rebuilt in the wrong place may extend a problem; a survey-correct rebuild fixes it.

Specific situations Texas ranchers actually face

Beyond the foundation rules above, here are the specific fence-law questions that come up most on working Texas ranches:

"My neighbor's cattle keep getting through my fence. Am I responsible for the damage?"

In a closed-range county, no — your neighbor is responsible for containing their animals, and you have a damages claim if their negligence (poor fence on their side, animals known to be escape-prone) caused harm to your property. In an open-range county, you have less recourse; the burden of "fencing out" was on you.

Either way, document everything: photos of the damage, photos of where the animals came through, dates, and the fence condition on both sides.

"Can I build an electric fence in Texas?"

Yes. Texas has no statewide prohibition on electric fences for livestock containment. The only restrictions are typically local (some HOA-bound subdivisions, some city limits) and generally don't apply to working agricultural land. The energizer must be UL-listed or equivalent (a safety standard, not a Texas-specific rule), and most counties recommend signage on perimeter electric fences along public roads — but this is best practice, not statutory.

If you're sizing an electric fence energizer, our charger sizing guide walks through the math. For component selection, see the energizers collection and the polybraid wire buyer's guide.

"Can I tear out an old fence that crosses my property?"

If the fence is on your property and your neighbor doesn't have an easement or prescriptive right, generally yes. But — see the adverse-possession point above. If the old fence has been in place for decades and may be on or near the actual property line, get a survey first. A torn-out fence followed by a survey-driven property-line correction is a clean process; an adversarial property-line dispute after the fence is gone is messy.

"My fence borders a state highway. Are there special rules?"

Yes. Texas Transportation Code and TxDOT rules require landowners to maintain fences along state highway rights-of-way at a height and condition that prevents livestock from entering the roadway. The "lawful fence" standard above generally satisfies this, but if a vehicle hits livestock that escaped through a fence in disrepair, the landowner's liability exposure goes up significantly. Inspect and maintain highway-adjacent fences first when prioritizing repairs.

"Open-range and closed-range — what about the road?"

Texas Transportation Code §347.012 imposes a duty of reasonable care on livestock owners to prevent animals from entering state-numbered highways, regardless of whether the county is open or closed range for fencing purposes. In other words: even in an open-range county, you can't let your cattle wander onto US-90.

Building a Texas-compliant ranch fence: what we'd actually do

Given the body of law above, here's how a modern Texas perimeter fence typically goes together:

For a closed-range cattle operation on a working ranch: - 5-strand 12.5-gauge high-tensile wire with top wire at 48 inches (meets the §143.028 "4 feet above ground" minimum), Class III galvanized for 30+ year service life. See the high-tensile wire and cable collection. - Top wire electrified for active deterrence — most cattle never test the lower wires once they've learned the top wire. Use T-Post Pinlock Insulators on steel posts or screw-in ring insulators on wood posts; see the full insulators collection. - Posts on 25-30 ft centers — comfortably inside the statutory 30-ft maximum, and well within hi-tensile's 50-ft span capability. - Corner H-braces with Gripple Plus Anchor Kits for high-load corner construction. - Mechanical splices with C23 crimp sleeves — no hand-twisted splices; they fail and create liability exposure when the fence stops containing cattle. - Energizer sized to perimeter length — see the energizers collection and our charger sizing guide. - Grounding system sized for Texas soil conditions (3 ft of ground rod per joule of energizer, more in dry caliche/sandy soil — Texas drought conditions can effectively halve grounding performance). See the grounding collection.

For an open-range county: the same fence, with the recognition that the legal duty is shifted but the practical need for a real fence isn't.

For boundary fences between neighbors: the same fence, with a written cost-share agreement before construction.

A correctly built fence on this spec exceeds the §143.028 statutory minimum, holds up for 30+ years, and gives you the documentation (build photos, materials receipts, survey records) to defend any future "your fence is inadequate" claim.

When to call a lawyer (and when not to)

Not every fence question is a legal question. Most are maintenance, sourcing, or design decisions. But these situations are worth a phone call to a Texas agricultural-law attorney before you act:

• Boundary disputes where a survey shows the fence is in the wrong place, especially if the fence is old.
• Adverse possession claims by a neighbor based on a fence location.
• Damages claims from a vehicle-livestock collision involving your animals.
• Partition fence disagreements where you and a neighbor disagree about who pays.
• HOA or subdivision restrictions that appear to prohibit livestock fencing on your property.

Most county Farm Bureaus, AgriLife Extension agents, and county attorneys can also offer guidance on routine questions at no cost. The Texas A&M AgriLife Extension publication "Texas Fence Law" is a free, current, and well-cited resource for ranchers wanting deeper detail.

Bottom line

Texas is closed-range in most counties — your duty is to fence livestock in, not your neighbor's to fence them out. A "lawful fence" under TX Ag Code §143.028 is 3 strands of barbed wire at 4 ft on 30-ft posts (or equivalent in board, rail, stone, or modern high-tensile electric). There is no statewide partition fence law requiring neighbors to share cost — get any cost-share in writing. Modern high-tensile electric perimeter fence meets or exceeds the statutory standard when built to comparable height and post spacing, and gives you a 30-year service life.
