"My neighbor's fence is on my property — what are my options?"

How a fence ends up on someone else's land — and why it happens more than you'd think

When a fence is built without a professional survey — which is the case for the vast majority of residential fences — the builder is usually eyeballing the boundary, guessing based on an old wooden stake that has shifted, or trusting a rough measurement from a deed that doesn't translate cleanly to the ground. The result is that fences routinely end up anywhere from a few inches to several feet off the true property line. Neither neighbor may have known at the time it was installed.

Property boundaries are defined in legal documents — your deed, and the recorded plat map for your subdivision — but those documents describe the line in abstract terms like metes and bounds or lot dimensions. Translating that description onto actual soil requires a licensed land surveyor. Without that step, even a well-intentioned fence installer can get it wrong. In older neighborhoods, the problem compounds over time as original stakes are lost, lots are re-subdivided, and fences are replaced in the same wrong location, generation after generation.

The critical distinction is between a fence that was placed incorrectly by mistake and a fence placed deliberately to grab land. Both situations give you the same legal options, but they tend to resolve very differently in practice. Most encroachments are genuine mistakes, and most neighbors will cooperate once the survey evidence is in front of them.

Fence encroachments show up in several different ways

The underlying problem is the same — a structure sitting on land you own — but the specifics of your situation shape which approach makes most sense.

Leaving an encroachment unaddressed can cost you more than just yard space

The most immediate consequence of ignoring a fence encroachment is the loss of use of your own land. But the legal risk over time is more serious: in most U.S. states, a neighbor who openly, continuously, and exclusively uses a strip of your land for a statutory period — which ranges from 5 years in some states to 21 years in others — can eventually claim ownership of that strip through adverse possession. The fence being there, and you not objecting to it, can be used as evidence that the use was uncontested. Acting now, even just by sending a written notice that you do not consent to the encroachment, interrupts that clock.

There are also practical consequences when you go to sell. Title insurance companies will flag a fence that doesn't align with the surveyed boundary as a defect, which can delay or kill a closing. Buyers will either walk away or demand a price reduction and a legal resolution before they proceed. Dealing with this on your own timeline is considerably less stressful — and less expensive — than dealing with it under the pressure of a pending sale.
