Neighbor's Tree Over Your Property? New York Rules (2026)

General information, not legal advice. For an active dispute, talk to a real estate attorney.

Branches over your yard: you can trim to the line

New York follows the self-help rule. A neighbor whose yard is overhung can cut the branches back to the boundary, and several New York trial courts have said the neighbor should trim back to the line first rather than sue. If branches or roots actually damage your property, you may also have a nuisance claim. The limits on trimming:

• Only to the property line. Not one cut past it.
• From your side. You or your contractor can't go onto the neighbor's land, or climb their tree from their yard, without permission.
• Don't kill or wreck the tree. Taking so much that the tree dies or becomes unstable is treated as injuring it.
• You pay. The neighbor generally isn't required to pay for trimming you choose to do.

In practice, a short conversation first makes the job easier. A crew working from both sides can make proper pruning cuts at branch collars instead of flat cuts at a survey line. See tree trimming on Long Island.

Roots under your driveway or patio

The same back-to-the-line idea applies to roots that cross onto your land, but roots are trickier than branches. Cutting large structural roots close to the trunk can kill the tree or leave it ready to tip, and on Long Island's sandy soil a tree with cut anchor roots is a real wind risk. That damage could land you in the penalty below, and the tree could land on someone. Have an arborist say which roots can safely be cut before you dig.

Cutting a tree on the wrong side of the line is expensive

RPAPL § 861 lets an owner sue anyone who cuts, removes, injures or destroys a tree on their land without consent, for treble the stumpage value or $250 per tree, or both, plus the cost of restoring the land. In 2025 New York's highest court described the treble part as punitive. A defendant who proves by clear and convincing evidence that they believed the land was theirs can avoid the treble amount, but still owes the single damages.

Before any removal near a fence or hedge line, find your survey (it's usually in your closing papers) or have the line staked. Contractors are liable too, so a good crew will ask where the line is.

Their tree fell on your property: who pays?

Start with your own homeowners policy. It typically covers damage to your house, garage or fence from a neighbor's tree, minus your deductible, and often pays a limited amount to remove it from the structure, commonly about $500 per tree and $1,000 per storm. See who pays when a tree falls.

Your neighbor is a different story. New York courts generally hold a tree owner liable only if they had actual or constructive notice that the tree was defective: they knew, or a reasonable look would have shown, that it was dead, rotten or failing. Owners aren't expected to keep inspecting healthy-looking trees for hidden decay. A healthy tree blown down in a storm is usually nobody's fault, legally.

A dead tree next door: put the owner on notice

You can't cut down a neighbor's dead tree, but you can make sure they can't later say they didn't know. Send a short, dated letter or email with photos of the dead branches, fungus, cracks or lean, and keep a copy. If the tree later fails and damages your property, that notice is what turns "act of nature" into a claim. The warning signs to photograph are in the leaning tree guide.

Town and village rules still apply

Even with your neighbor's blessing, the tree may need a permit. North Hempstead (6"+), Oyster Bay (8"+) and Huntington regulate many private-property trees, and incorporated villages often have their own codes. Trees in the strip between the sidewalk and the curb usually belong to the town or village. Check the permit guide.

Splitting a removal with your neighbor

Many disputes end with the two of you splitting a removal. Get one written quote that covers the tree, the stump, cleanup and who's paying what, and have both owners sign it. A tree that straddles the line needs both owners' agreement before anyone cuts. Typical prices are in the tree removal cost guide.
