A real estate encroachment happens when a neighbor’s fence, shed, addition, driveway, tree limbs, or roots cross your property line and sit on your land. These boundary violations range from a fence a few inches over the line to a garage built partly on your lot, and the consequences fall on you: a clouded title, a stalled sale, and the risk that the neighbor could eventually claim legal ownership of the strip they are using.1An encroachment occurs when a neighbor’s structure, landscaping, or other physical object crosses your property line onto your land. Most encroachments are unintentional. Ignoring one is what turns a fixable problem into an expensive one.
What Counts as an Encroachment
Structural encroachments are the ones that cause the most trouble at closing because they show up on surveys and title searches. The common examples are fences installed a foot or two past the surveyed line, detached sheds or garages that straddle the boundary, and home additions such as decks or sunrooms that extend beyond the lot. Roof eaves, gutters, and drainage systems that project into a neighbor’s airspace count too.
Non-structural items encroach just as easily. Retaining walls, raised garden beds, and paved walkways installed by a neighbor can drift across the line during construction. Tree branches hanging over the boundary and roots spreading underground are among the most common encroachments in residential neighborhoods.
You generally have the right to trim a neighbor’s branches and roots back to the property line, but that right has limits. You cannot enter the neighbor’s yard to do the work, and you cannot damage the tree’s health or structural integrity. Destroying a tree or ruining its appearance with aggressive cutting can make you liable for damages, sometimes up to three times the tree’s value. Give the tree owner written notice and a chance to handle it first. Any branches or debris you cut are yours to dispose of.
Why Encroachments Matter
Sales and Financing
A boundary survey ordered before closing will surface any structures or features crossing the line, and lenders pay attention. Under FHA guidelines, an encroachment by the subject property onto a neighbor’s land can jeopardize loan approval unless the appraiser determines it does not affect marketability. Conventional lenders apply similar scrutiny. A garage sitting partly on the neighbor’s lot is the kind of issue that delays or kills a deal.
Most states also require sellers to disclose known encroachments, usually on a standardized form covering boundary disputes, easements, and encroachments the seller actually knows about. Failing to disclose a known encroachment can expose you to fraud or misrepresentation claims after closing.
Title Insurance
Standard title insurance policies generally do not cover encroachments. Any encroachment identified before purchase gets listed as an exception in the policy, so you have no coverage for it from day one. Encroachments discovered later are rarely covered under a basic policy either. Extended or enhanced policies offer broader protection, but read the exceptions schedule rather than assume you are covered.
Adverse Possession
Ignoring an encroachment can cost you the land itself. Under the doctrine of adverse possession, someone who occupies your property long enough can eventually claim legal title. The required period varies by state, from as few as five years to as many as twenty-one. The occupier must generally show that possession was continuous, hostile (meaning without the owner’s permission), open and obvious, actual, and exclusive.
The “hostile” element is the one you can most easily defeat. If you give written permission for the encroachment to remain, the neighbor’s use is no longer hostile, and an adverse possession claim fails. That is why a written agreement matters even when the current situation feels fine. A handshake understanding does not create the paper trail you need to block a future ownership claim. Once the statutory period runs, the occupier can file to obtain legal title, and you lose the right to object.
Confirming Where the Line Actually Sits
Before you can prove an encroachment exists, you need to know exactly where your boundary runs. The legal description on your deed is the starting point, using either metes-and-bounds descriptions or lot-and-block references. But a deed description alone does not tell you where the line falls on the ground. For that, hire a licensed land surveyor.
The surveyor uses the deed, historical records, and specialized equipment to physically locate your boundary markers, typically iron pins or monuments buried at the corners. The result is a certificate of survey showing the exact dimensions of your parcel and the location of every structure relative to the lines. This document is the factual backbone of any encroachment claim, whether you are negotiating or in court. A standard residential boundary survey generally runs between $500 and $2,500, though large, irregularly shaped, or heavily wooded lots can cost more.
Once markers are placed, do not let anyone tamper with them. In nearly every state, knowingly removing, defacing, or destroying a survey boundary marker is a criminal offense, typically a misdemeanor. The person who disturbs the markers is also usually liable for the cost of a new survey and your attorney fees. If a marker looks disturbed, get a surveyor back out promptly.
Resolving It Without a Lawsuit
Written Encroachment Agreement
The simplest fix that still protects your rights is a written encroachment agreement. It acknowledges that a specific structure or feature crosses the boundary, spells out whether it can remain and for how long, and assigns responsibility for maintenance or eventual removal. Include the legal descriptions of both properties, a detailed description of the encroaching object, and a clear statement that the neighbor’s use is permissive, not a claim of ownership.
Record the agreement with the county land records office. An unrecorded agreement binds only the two neighbors who signed it, so once one sells, the new owner has no obligation to honor terms they never agreed to. Recording puts future buyers on notice and keeps the arrangement in place through a change in ownership. County recording fees are modest, typically $10 to $90 depending on the jurisdiction.
Easement
An easement grants the neighbor a limited legal right to use the strip where the encroachment sits, while you keep ownership and title. It works well when removing the structure would be impractical or disproportionately expensive. Easements should be recorded, and their advantage over an informal arrangement is that they create a legally recognized interest that lenders and title companies can work with in future transactions.
Lot Line Adjustment
When the encroachment involves a meaningful piece of land, selling the encroached strip to the neighbor is sometimes the cleanest fix. A lot line adjustment formally redraws the boundary between the two parcels. Both owners sign new deeds, and the adjustment must comply with local zoning and subdivision requirements. This eliminates the encroachment because the structure now sits on the correct owner’s land. Expect surveyor fees, recording costs, and possibly local planning approval.
Mediation
When direct talks stall but neither side wants a lawsuit, mediation offers a middle ground. A neutral mediator helps both parties work toward a solution, and many courts encourage or require mediation before a boundary dispute goes to trial. The process is confidential, faster than litigation, and can produce creative outcomes like shared-use or compensated boundary adjustments that a judge might not order.
When the Neighbor Won’t Cooperate
A quiet title action asks a court to formally declare who owns the disputed land. You present the deed, the survey, and the chain of title, and the judge issues a ruling that clears competing claims. This is where the certificate of survey earns its keep. A quiet title judgment resolves the ownership question, but by itself it does not force the neighbor to remove anything.
To get the encroachment physically removed, you typically need an ejectment action seeking to recover possession of the occupied land. If you win, the court can order the neighbor to dismantle the encroaching structure within a set timeframe. Courts weigh several factors before ordering removal: whether the encroachment was intentional, how much harm it causes you, and whether removal would be disproportionately destructive compared to the benefit. A fence two feet over the line is an easy removal order. Half a house on your lot is more complicated.
Costs vary widely. Simple cases with clear survey evidence may resolve for a few thousand dollars; contested cases that go to trial can exceed $10,000 in legal fees.
What to Do First
The moment you suspect a boundary violation, get a professional survey. Everything else depends on an accurate, current depiction of where the line runs. Then talk to the neighbor before calling a lawyer. Most encroachments are genuinely accidental, and a direct conversation about the survey often leads to a reasonable agreement.
If the neighbor is cooperative, put the resolution in writing and record it. The right instrument (encroachment agreement, easement, or lot line adjustment) depends on the size of the encroachment and whether you want the structure to stay. If the neighbor refuses to engage, send a written notice stating that any continued use of your land is without permission. That single step protects you against a future adverse possession claim and creates a record if you eventually need to go to court.
Waiting is the worst move. Every year an encroachment goes unaddressed, the adverse possession clock keeps running, removal gets harder, and the impact on your title and resale value grows. Acting early keeps your options open and your costs low.
