My Neighbor's Fence Is on My Property in New York. What Can I Do? Boundary Disputes, Adverse Possession and Quiet Title, Explained by a Long Island Real Estate Attorney (2026)

What can I do if my neighbor's fence is on my property in New York?

You can compel removal, recover damages, and have a court fix the boundary permanently, but each of those starts with a survey, not a confrontation. In New York the remedy for a structure that encroaches on your land is an action under RPAPL 871, which authorizes the court to grant an injunction directing removal of the encroaching structure or, where that would be unfair, damages instead. In practice that claim is joined with a cause of action under RPAPL Article 15 to compel a determination of the claim to the disputed strip, which is what people mean by a quiet title action.

Before any of that, you need to know where the line is. Most fence disputes I see in Nassau and Suffolk begin with a homeowner reading a tax map, a listing diagram or a survey from 1987 and concluding the neighbor took two feet. Sometimes they did. Sometimes the old survey was wrong, the monuments moved, or the fence was set inside the line by the prior owner on purpose. A licensed land surveyor who stakes the corners is the only evidence a court will take seriously, and a survey that is current is what an attorney will put in the demand letter. New York City's own 311 guidance tells residents the same thing for fence encroachments: both sides end up with surveys, and the court wants them recent.

Then the sequence is a letter, a conversation, and only then a lawsuit. The large majority of fence encroachments are resolved by the neighbor moving the fence, by a written agreement that lets it stay until it is replaced, or by a recorded boundary line agreement that redraws the line where both owners actually treat it. Court is for the cases where the neighbor refuses to acknowledge the survey or claims the strip is theirs.

Can my neighbor claim my land because their fence has been there for years?

Usually not anymore, if the fence went up after July 7, 2008. RPAPL 543(1), added in the 2008 overhaul of New York's adverse possession law, provides that the existence of de minimis non-structural encroachments, including fences, hedges, shrubbery, plantings, sheds and non-structural walls, is deemed permissive and non-adverse. Subdivision 2 does the same for lawn mowing and similar maintenance across the line. Permissive use is the opposite of adverse use, so a de minimis fence encroachment cannot start the ten year adverse possession clock running at all.

The 2008 law also changed what the neighbor has to prove. Adverse possession in New York requires ten years of possession that is hostile, under a claim of right, open and notorious, exclusive and continuous (RPAPL 501 and CPLR 212). Since 2008, a claim of right means a reasonable basis for the belief that the property belonged to the possessor. A neighbor who had a survey in the drawer showing the fence was over the line cannot honestly claim that belief, and that is exactly what the 2008 Legislature set out to stop. I break down every element in my post on adverse possession in New York.

Now the hard truth, which is the part most online answers skip. Two things can still cost you the strip. First, the word is de minimis. An eight foot encroachment by a hedge was held by the Second Department in Wright v Sokoloff to raise a question of fact about whether it was de minimis at all, so a fence set several feet into your yard, or a fence with a structural footing, is not automatically protected by RPAPL 543. Second, and more important, the 2008 amendments do not reach title that had already vested. If the fence was installed in 1995 and sat there openly and exclusively for ten years, the neighbor's title to the strip may have vested in 2005 under the old law, and the Second Department applies the pre-2008 rules to those claims. It said so again in Kuhbach v Mordas in October 2025, a case about a livestock fence installed in 1993 to 1995. If your dispute involves an old fence, the date it went up is the single most important fact in the case, and it is worth real effort to pin down.

How does a New York boundary dispute get resolved, step by step?

Most boundary disputes on Long Island follow the same path, and the ones that end early end because the owner did the first three steps correctly:

1. Get a current licensed survey with the corners staked (weeks 1 to 4). The surveyor locates the recorded boundary from the deed description and the filed maps, sets stakes, and measures how far the fence sits over the line. Ask for the encroachment to be noted on the survey itself.
2. Pull the history (weeks 2 to 6). When was the fence built? Who built it? Were there earlier surveys showing it? Permits at the town building department, prior listing photos, aerial imagery and your own closing survey all help date the fence. This step decides whether RPAPL 543 protects you or whether you are looking at a pre-2008 adverse possession problem.
3. Send a written demand with the survey attached (week 4 to 8). The letter identifies the encroachment, asks for removal or relocation within a stated time, and proposes alternatives: a written license that lets the fence stay until it is replaced, or a boundary line agreement. A letter from an attorney changes how seriously the neighbor and their insurer take it.
4. Negotiate (months 2 to 4). Many fence cases settle here. If the encroachment is a few inches, a recorded license or agreement is often cheaper for both sides than moving the fence. If it is feet, the neighbor usually moves it once they see a survey and a lawyer's letterhead.
5. File the action (month 3 to 6). The complaint pleads RPAPL 871 for removal of the encroaching structure and RPAPL Article 15 to compel a determination of title to the strip, and a notice of pendency is filed under CPLR 6501 so the dispute is on the public record against the neighbor's title.
6. Discovery and expert surveys (months 6 to 14). Each side's surveyor produces a report. If the neighbor pleads adverse possession, discovery focuses on the age of the fence, who maintained the strip, and what each owner believed.
7. Summary judgment or trial (months 12 to 24). Boundary cases turn on documents and surveys more than on testimony, so many are decided on motion. Where the date of the fence or the de minimis question is disputed, there is a trial.
8. Judgment and recording (final weeks). The judgment under RPAPL 1521 declares who owns the strip, orders removal or awards damages, and forever bars the losing party from reasserting the claim. A certified copy is recorded with the county clerk so every future buyer and title company sees it.

How much does it cost to fight a fence encroachment in New York?

The court's filing fees are $210 for the index number under CPLR 8018 and $95 for the request for judicial intervention under CPLR 8020. The money that matters is the survey, the attorney, and whether the case goes past the demand letter. In my practice, a boundary matter that ends with a survey, a letter and a signed agreement costs a small fraction of one that goes through two expert surveyors and a trial on adverse possession. For the full fee picture, including title searches and uncontested cases, see what a quiet title action costs in New York.

Think about the value of the strip before you decide how far to go. A two foot strip along a 100 foot side yard in Nassau County is 200 square feet. On a quarter acre lot that is a real number, and it can matter enormously for a pool setback, a future addition, or a buyer's title insurance. A three inch overlap on a chain link fence is a title objection that a license agreement cures for a few hundred dollars in legal time. Spending five figures to litigate inches is a decision people regret. Spending it to recover a strip that blocks the addition you planned is not.

Damages are available but modest in most residential cases. RPAPL 871 lets the court award damages instead of removal where an injunction would be inequitable, and a trespass claim can recover the loss of use. The realistic prize in a fence case is the land and a clear title, not a check. If a neighbor removed or damaged trees on your side of the line in the process of putting up the fence, that changes. RPAPL 861 allows treble the stumpage value of each tree, or $250 per tree, or both, plus the cost of restoring the land, against anyone who cuts or injures trees on another's land without consent, with a reduced recovery only where the defendant proves by clear and convincing evidence a reasonable belief the land was theirs.

Can I just remove my neighbor's fence if it is on my land?

Do not. Even when the survey is on your side, cutting down or pulling out a fence you did not build is the fastest way to turn a strong case into a two way lawsuit. The fence is your neighbor's property even if it is sitting on your land, and destroying it invites a claim for the cost of the fence, a police report, and a judge who now sees two neighbors behaving badly instead of one. If the survey turns out to be wrong by a few inches, you have destroyed a fence that was legally placed.

There is a second, quieter reason. If your neighbor intends to claim the strip by adverse possession, the fence is their evidence of a substantial enclosure under RPAPL 522. Removing it does not erase a claim that already vested before 2008, and it hands them a story about an owner who knew the line was disputed and resorted to force. The court is the place that strong facts are rewarded. The backyard is not.

The one form of self help New York does allow is on the vegetation side, covered below. For a fence, the lawful path is the demand letter and, if needed, RPAPL 871. If you need to enter the neighbor's land to do work on your own fence or structure and they refuse, RPAPL 881 lets you petition the court for a temporary license to enter, on notice and with liability for any damage you cause. It is not a license to remove their property.

What if my neighbor says the fenced area is theirs now?

Then you are in a title dispute, and the sooner it is decided in court the less it costs you. A neighbor who claims the strip is asserting adverse possession, and the burden is on them to prove every element by clear and convincing evidence: ten years of possession that was hostile, under a claim of right, open and notorious, exclusive and continuous (RPAPL 501, CPLR 212). Since 2008, for claims that had not already vested, they also have to show a reasonable basis for believing the strip was theirs, and a de minimis fence or planting cannot be the basis of the claim at all under RPAPL 543.

The questions that decide these cases are concrete. When was the fence built, and by whom? Did you or a prior owner ever give permission, even casually? Permission defeats hostility, and in Pritsiolas v Apple Bankcorp the Second Department found that a fence allowed to remain as a neighborly accommodation was permissive, not adverse. Did the neighbor ever acknowledge your ownership, offer to buy the strip, or ask to keep the fence there? Each of those undercuts a claim of right. Did anyone have a survey showing the true line? A party who knew the land was not theirs has no reasonable basis for believing otherwise.

If the facts point to a pre-2008 fence that sat undisturbed for ten years, be honest with yourself about the likely outcome. The Second Department has repeatedly applied the old law to those claims, and under the old law the neighbor did not need a good faith belief; a substantial enclosure for ten years could be enough. In that situation a negotiated boundary line agreement, where you concede the strip in exchange for a clean recorded line and perhaps a payment, is often the better result than a quiet title action you may lose. I would want to see the surveys and the fence history before saying which path fits your lot, since those two facts drive nearly everything.

What about trees, hedges and branches over the property line in New York?

You may trim branches and roots back to your property line at your own expense, and you may not cut down, poison or structurally damage the tree. That is the long settled New York rule on overhanging vegetation, and the courts in the Second Department have applied it consistently: self help by trimming to the line is the remedy, and it does not extend to the main trunk or support system of the tree, or past the boundary onto the neighbor's land.

Hedges and plantings along the line fall under RPAPL 543 the same way fences do. A de minimis hedge encroachment is deemed permissive and cannot ripen into ownership, while a large one can raise a question of fact, as the eight foot hedge did in Wright v Sokoloff. A tree whose trunk straddles the line is generally treated as owned by both neighbors together, and neither should remove it without the other's consent.

Two statutes catch homeowners by surprise. RPAPL 843 makes a fence or structure over ten feet high, built to exclude a neighbor from light or air, a private nuisance that a court can enjoin. Ordinary six foot backyard fences are nowhere near that threshold, and their height is governed by your town or village code, not by state law, so a complaint about a tall fence usually starts at the building department. And RPAPL 861 carries treble damages for cutting or injuring a neighbor's trees without consent. A landscaper who clears brush on the wrong side of a disputed line can create a bigger liability than the fence itself.

What mistakes make a New York fence dispute worse?

Acting on a guess about the line, removing the fence yourself, and ignoring an old fence for years are the three that cost the most. A fourth is writing to the neighbor in anger before the survey is in hand, because that letter becomes an exhibit.

Here is the perspective I give homeowners who call about a fence. If the fence went up recently, the law is on your side and the problem is solvable with a survey and a firm letter. If the fence has been there for decades, the problem may already have solved itself in the wrong direction, and the right move is to find out quickly and negotiate from knowledge rather than litigate from hope. In either case, do not wait. A boundary problem that is ignored at your closing becomes a title objection at your sale, and the buyer's title company will not care how long you meant to deal with it. Reading the survey against the fence line is on my Long Island closing checklist for exactly this reason.

The permanent fix for any boundary dispute is a judgment or a recorded agreement. Everything short of that is a conversation that will repeat with the next owner.
