Tommy, Michael, Alla and Nick have already given you the ownership half of this correctly: it turns on where the trunk stands, not where the branches hang, and the right of way is usually wider than the pavement. Alla's point about locating the trunk is the right first step. Let me add the half that decides most of these cases, and it is not ownership. It is whether the owner knew, or reasonably should have known, that the tree was defective before the limb came down. Ownership tells you who to look at. Notice tells you who actually pays. So, was the defect knowable. A structurally sound tree that loses a limb in a storm is usually treated as an act of nature, and nobody pays. A tree with visible deadwood, a large cavity, fungal conks at the base, prior limb drops, or a fresh lean is a different story, because a court will ask whether a reasonable owner would have noticed and acted. Courts generally describe this as a duty to learn of defective conditions and then remedy them. What I would actually do this week: - Photograph the whole tree now, including the base and any dead limbs, with the date. - Pay for a written report from an ISA certified arborist. It runs a couple hundred dollars and it is the single most useful document in this situation, whichever way it comes out. - If the trunk turns out to be the state's, send written notice to your state DOT district office and keep the receipt. Written notice is exactly what turns "should have known" into "knew," and it shifts the exposure off you. - If the trunk is yours and the arborist says it is defective, either remedy it or accept that you are on the hook. Tell your homeowners insurance carrier before you admit anything to anyone else. Liability coverage generally responds to this, but only if you let them handle it. I am a real estate professional, not an attorney, and tree liability is genuinely state specific, so if someone has already been hurt or property was damaged, talk to a local attorney before you say anything in writing to the other side. My name is Zoltan Peresztegi and I work the South Bay and the Palos Verdes Peninsula here in Los Angeles County, so I am not the right person to walk your property line, but if you tell me the county you are in I am glad to point you to a strong local agent from my network who can pull the plat and the right of way width for you.
