Sending a certified letter warning your neighbor about a dead, visibly hazardous tree, having him ignore it entirely, and then being told you bear partial responsibility for the resulting damage because the warning made him “aware of the risk” is one of the more backwards liability arguments to come from an insurance company in recent memory.
That’s what one Washington homeowner is facing after a dead tree on his neighbor’s property finally came down during a windstorm last month, totaling his car and damaging the neighbor’s own fence on the way. He has photo documentation going back more than a year showing the tree was unmistakably dead, with no leaves, falling bark, and an already-split major branch. He sent a certified letter last October specifically asking his neighbor to remove it because it was leaning toward his parking area. The neighbor never responded.

His auto insurance is now pursuing subrogation against the neighbor for the totaled car, which is proceeding as expected. What’s unexpected is the neighbor’s homeowner’s insurance company contacting him directly to suggest he shares responsibility for the fence damage because his warning letter “contributed to his awareness of the risk,” and asking him to sign a document acknowledging shared causation.
Why This Argument Doesn’t Hold Up
The legal theory the insurance company appears to be advancing inverts the basic logic of premises liability and negligence law. A property owner has a duty to address known hazards on their own property, and a neighbor who identifies and reports that hazard is doing exactly what the law expects a reasonable person to do. Documenting a dangerous condition and notifying the responsible party isn’t a contributing cause of the harm that follows from inaction. It’s evidence that the responsible party had actual notice and failed to act, which typically strengthens a negligence claim against the property owner rather than diluting it.
If anything, the certified letter is one of the most damaging pieces of evidence against his neighbor. It establishes that the tree’s danger was identified, documented with photos, and communicated formally more than a year before it fell, and that the neighbor did nothing in response. An insurance company attempting to flip that documentation into shared liability for the person who sent the warning is making an argument that doesn’t track with how negligence and causation actually work under Washington law or anywhere else.
What “Shared Causation” Would Actually Require
For him to bear any legal responsibility for the fence damage, there would need to be some action or inaction on his part that contributed to the tree falling or to the fence being in the path of its fall. Warning the property owner about a hazard he didn’t create and had no authority to remove doesn’t meet that standard under any reasonable interpretation of comparative negligence principles. He doesn’t own the tree, didn’t cause its condition, and took the appropriate step of notifying the person who did have control over it.
The document they’re asking him to sign, acknowledging shared causation, would be an admission against his own interest with no clear legal basis supporting it. Signing it could complicate his own insurer’s subrogation case and potentially expose him to liability he doesn’t actually have. There’s no scenario where signing that paperwork benefits him.
Why an Attorney Is Worth Involving Now
This is exactly the kind of situation where a brief consultation with an attorney, even a single paid hour, pays for itself many times over. An attorney can confirm in writing that the shared causation theory has no legal merit, that he has no obligation to sign anything, and can communicate directly with the insurance company on his behalf going forward. Having an attorney respond on his letterhead also tends to end this kind of overreach quickly, because insurance companies testing liability theories against unrepresented individuals often back off once a represented party signals they understand their rights.
A consumer protection or personal injury attorney in Washington could also flag whether the insurance company’s tactics here, pressuring an uninvolved third party to sign a liability admission with no legal basis, cross into bad faith insurance practices, which is regulated conduct in Washington State.
What He Should Do in the Meantime
He’s already doing the most important thing, which is declining to sign anything without understanding what it means. He should continue that approach and stop communicating directly with the neighbor’s insurance company at all once he has an attorney or at minimum should redirect all communication to be in writing only, so there’s a clear record of what was asked and what was said. He should also preserve every piece of documentation he has, the photos of the dead tree, the certified letter and its return receipt, and any correspondence from the insurance company, since all of it supports both his position and his own insurer’s subrogation claim.
His own auto insurer’s subrogation team has an interest in establishing that the neighbor was negligent, since that’s the basis for recovering the deductible and the loss from the neighbor’s homeowner’s policy. Sharing his documentation with his own insurer, if he hasn’t already, reinforces that case and works in the same direction as protecting himself from the fence liability claim.
The Neighbor Relationship
Six years of living next door without conflict, now followed by complete silence since the incident, suggests the neighbor may be aware of how clearly the documentation establishes his own negligence and is avoiding the conversation entirely. That silence doesn’t change the legal facts. The tree was visibly dead, he was formally warned with photographic evidence, he didn’t act, and the consequences that followed are the predictable result of that inaction. An insurance company trying to redirect part of that liability onto the person who did everything right isn’t a reflection of any actual exposure he has. It’s a tactic, and it’s one that doesn’t hold up once someone with legal training is looking at the actual facts.
