can my neighbor cut my tree branches?

In my state, you can cut straight up on the property line. I did that with a rental I own because the tree is HUGE and the branches threatened my garage. The tree people cut straight up from the fence.

Mark, your neighbor probably had the right to trim branches that actually extended onto their side of the property line, but that right has limits. Oklahoma law recognizes a property owner's right to deal with tree branches or roots that encroach onto their property. The Oklahoma Supreme Court has specifically recognized that offending branches or roots may be cut back at the boundary line, and advance notice generally is not required when the work can be done from the neighbor's own property. If your neighbor simply cut the overhanging portions back to the property line, the fact that they did not ask you first probably does not, by itself, make the trimming unlawful. But if they cut branches past the property line, entered your property without permission, or pruned the tree so severely that they unnecessarily injured, destabilized, or killed it, you could have a substantially different situation. Because you describe the trimming as taking a "big slice" out of a mature tree, I would take photographs immediately and have an ISA-certified arborist examine it. Ask the arborist to document whether the cuts were proper pruning, whether any cuts appear to have been made on your side of the property line, and whether the pruning has materially damaged or endangered the tree. If the damage is significant, it would also be worthwhile to confirm the exact boundary with a survey and speak with an Oklahoma real-estate/property attorney before confronting the neighbor or agreeing to anything. The bottom line: your neighbor could generally trim branches extending into their yard, but that does not give them an unlimited right to damage your tree. Whether what happened here crossed that line will depend heavily on where the cuts were made and what effect they had on the tree.

Mark, short version: he was probably allowed to cut what hung over his side, but he was not allowed to hurt your tree doing it, and Oklahoma takes damage to trees seriously enough that you may have a real claim. Oklahoma follows the common law self-help rule. A landowner whose property is intruded on by branches or roots from a neighboring tree can cut those branches or roots off at the property line. That goes back to a 1947 Oklahoma Supreme Court case, Mead v. Vincent. So the act of trimming was not, by itself, trespass, and he did not need your permission. Here is where it turns, and this is your issue. That right ends at the property line and it ends where the cutting starts damaging the tree. If someone trims so aggressively that the tree is damaged or dies, they are liable for it, and Oklahoma allows recovery of up to three times the tree's value for injury to trees. "A big slice out of the tree" is exactly the fact pattern that gets there. Cutting overhanging limbs is one thing. Taking a third of the canopy off one side and destabilizing a mature tree is another. What I would do this week, in order: - Photograph it now, from several angles, with something for scale, and get a shot showing where the cut line sits relative to the actual property line. Photos age badly as evidence if you wait. - Get a certified arborist out (look for ISA certification) and pay for a written assessment. You want three things in writing: whether the tree is now damaged or likely to die, whether it is now a hazard or structurally unbalanced, and a value opinion on the tree. That document is the whole case if this goes anywhere. - Pull your plat or survey and confirm where the line actually is. A surprising number of these disputes turn out to be about a fence that was never on the line. One thing to watch that people miss. If the trimming left the tree unbalanced and it now leans toward his house, the liability can flip onto you as the owner of a known hazardous tree. So the arborist report protects you both ways. Get it either way. And since this is a real estate forum, the resale angle: a damaged mature tree, an unresolved neighbor dispute, and any pending claim are all things that surface later. A neighbor dispute in writing is a disclosure item in most states when you sell, and mature trees are one of the few landscape features an appraiser will actually assign value to. So it is worth resolving cleanly rather than letting it sit. I am a real estate professional, not an attorney or an arborist. For the treble damages piece, an hour with an Oklahoma property attorney after you have the arborist report will tell you quickly whether it is worth pursuing.

The short answer is: usually yes—but with important limits. In most U.S. states, including New York, a neighbor generally has the right to trim branches or roots from your tree up to the property line, even without asking your permission. However, they cannot go onto your property to do it without your consent, and they cannot cut beyond the property line. There are also important restrictions: They cannot intentionally damage or destroy the tree. If they prune so aggressively that the tree becomes unhealthy, unstable, or dies, they may be liable for the damage. They cannot cut branches that are entirely on your side of the property line. They are generally responsible for the cost of trimming branches that overhang their property. Based on what you described—"it's like a big slice out of the tree"—the key question is whether they: Cut only the portions that extended over their property, or Cut so much that they crossed the property line or seriously damaged the tree. If the tree now looks significantly unbalanced or you're concerned about its health, I'd recommend: Take clear photos of the tree from several angles as soon as possible. If possible, find older photos showing what it looked like before. Have a certified arborist inspect it to determine whether the pruning was proper or whether it harmed the tree. If the arborist concludes the tree was damaged, you may have a claim against your neighbor for the loss in value or the cost of treatment.
