A tree from next door is now lying across your fence, your car, or your roof. The first question everyone asks is who pays for this, and the answer is less intuitive than most people expect.
What follows is general information about how these situations typically work, not legal advice. For an actual dispute with real money involved, talk to an attorney licensed in Washington.
The general rule: healthy tree, act of nature
If a healthy tree falls because of a genuine storm event, the property owner where it landed is generally the one who deals with it, typically through their own homeowners insurance. Your neighbor is usually not liable simply for having owned a tree that the wind knocked over.
This strikes people as unfair, and it is worth understanding the logic: the neighbor did not do anything wrong. A sound tree came down in weather nobody controls. Liability generally requires fault, and there was none.
The exception that changes everything: negligence
The picture shifts substantially if the tree was already a known problem. If a tree was visibly dead, obviously decayed, clearly leaning, or had been the subject of prior complaints, and the owner did nothing about it, the analysis moves toward negligence — the owner knew or reasonably should have known there was a hazard and failed to act.
The practical question becomes: was this failure foreseeable?
A green, structurally sound Douglas fir that came down in a windstorm is one thing. A tree that had been dead for two years, with mushrooms at the base, that the neighbor had been asked twice to deal with, is another.
Which is why documentation matters so much
If you are worried about a neighbor’s tree before it falls, what you do now determines your position later.
- Photograph the tree. Date-stamped, showing the defect clearly — the lean, the deadwood, the fungus, the crack.
- Put your concern in writing. A polite letter or email creates a record that the owner was notified. A conversation over the fence does not.
- Get a written assessment. This is the strongest step available to you. A hazard tree assessment from an ISA Certified Arborist is documentation from a credentialed professional that the tree presented a foreseeable hazard on a specific date. That is a materially different piece of evidence than your own opinion.
- Keep copies of everything, including any reply.
Most neighbors, shown a professional report saying a tree is likely to fail toward their house, deal with it. Most of these situations resolve without lawyers.
What you can and cannot do about overhanging limbs
Different question, different answer. Branches from a neighbor’s tree that extend over your property line can generally be trimmed back to the property line at your own expense — but with real limits:
- You can generally trim only to the line, not beyond it
- You cannot enter their property to do it without permission
- You cannot prune so severely that you damage or kill the tree, which can expose you to liability for the value of the tree
- The trunk belongs to whoever owns the land it stands on, regardless of where the canopy reaches
A tree whose trunk straddles the line is typically treated as jointly owned, and neither owner can remove it unilaterally. Those situations need agreement, and often a professional to help both parties understand the actual condition of the tree.
What to do in the first day after a tree comes down
- Safety before anything else. Stay clear of downed lines and assume they are energized. Call the utility. A fallen tree can also hold enormous stored tension and shift without warning.
- Photograph everything before any cleanup — the tree, the damage, the base and root plate, and any visible decay or defect. The base of the fallen tree often shows whether it was rotten, and that evidence disappears once the wood is hauled away.
- Call your insurer and open a claim. Do this even if you think the neighbor is responsible; your carrier can pursue their carrier if warranted.
- Get the immediate hazard handled. If a tree is on a structure or blocking access, emergency removal comes before the liability question is settled. Do not let a dispute leave a tree on your roof.
- Keep receipts for everything you spend.
Insurance realities worth knowing now
Homeowners policies commonly cover damage to structures from a fallen tree, often with limited coverage for debris removal, and frequently exclude damage to landscaping and fences or cover it only minimally. Coverage for removing a tree that fell without hitting anything is often limited or absent.
Read your policy before you need it. The single most useful thing you can do this fall is find out what your coverage actually says about tree damage, debris removal, and deductibles — while the sun is still out.
