A tree comes down across the property line. The damage is real, the tree was clearly theirs, and the instinct is obvious: they own the tree, they pay for the tree. In Maryland that instinct is usually wrong, and understanding why — before the storm, ideally — is worth real money.
We're a tree company, not attorneys or insurance adjusters. What follows is the general framework as it plays out on jobs we run in Howard County. For anything contested or expensive, talk to your carrier and, if it's serious, a Maryland attorney.
The default rule: your tree, your problem — and their tree, also your problem
Maryland treats a tree that falls from natural causes as an act of God. Wind, saturated soil, ice load, a summer thunderstorm — nobody caused it, so nobody is at fault. The consequence: the owner of the damaged property handles the damage. Your house, your fence, your car, your claim, your deductible — even though the trunk is rooted in the yard next door.
This feels unjust the first time you hear it, but it's the same principle that protects you when your tree lands on their shed. It cuts both ways, and it's the reason both of you carry homeowners insurance in the first place. Your policy generally covers the structural damage and the removal of the tree from the structure; what it typically won't cover is a tree that fell in the open yard and hit nothing. We go through the coverage mechanics in detail in our Maryland tree removal insurance guide, including the debris-removal sublimit most people don't know they have.
The exception that actually matters: negligence
Liability shifts to the tree's owner when the fall wasn't really an act of God at all — when the tree was already failing and the owner did nothing. As Maryland courts have framed it, the owner is responsible if they knew or reasonably should have known the tree posed a danger to adjoining property.
In practice, three things have to line up:
- The tree was visibly hazardous. Dead or largely dead, major decay, a significant lean that developed recently, a split trunk, mushroom conks at the base, a hollow cavity. Not "it was big and old" — big and old is not a defect.
- The owner knew, or a reasonable person would have. A completely dead tree in a front yard is hard to claim ignorance of. Decay visible only from your side of a fence is a harder argument.
- They had a reasonable chance to act and didn't.
Where cases are won and lost is that middle element. Which brings us to the single most useful thing in this entire post.
Build the record before the tree falls
If a neighbor's tree genuinely worries you, what you do now determines who pays later. Verbal conversations over the fence are close to worthless afterward — they're deniable and undated.
- Photograph the tree. Wide shot showing its position relative to your house, plus close-ups of the specific defect. Photos carry timestamps; that matters.
- Put your concern in writing. A dated letter or email describing the specific condition you've observed and asking them to have it assessed. Keep a copy. Certified mail is stronger still. This is the step that converts "should have known" into "was told."
- Get an arborist's written assessment. This is the piece that carries real weight. A professional inspection documenting decay, structural defect, or mortality, dated and on paper, is very difficult for an insurer to wave off. It's inexpensive relative to what it protects.
- Notify your own insurer if the risk is significant. It puts the concern on record with the party who'll be writing the check.
Homeowners who do these four things and then have the tree come down are in a genuinely different position from homeowners who were also worried but said nothing. Same tree, same storm, very different outcome.
What happens after it falls
Photograph everything before anything moves. The position of the trunk, the root plate, the damage, the visible condition of the wood at the break. If the tree was rotten, the break face will show it — and once the tree is cut up and hauled away, that evidence is gone permanently. This is the most common mistake we see: the cleanup happens fast, and the proof leaves with it.
Then make it safe. Documentation matters, but not more than an unstable trunk over a bedroom. If there's an active hazard, that comes first — see what to do when a tree falls on your house, and call our 24/7 emergency line.
File with your own carrier. Even if you believe the neighbor was negligent. Your insurer pays out, then pursues theirs through subrogation — and if they recover, you typically get your deductible back. Letting your insurer fight that battle is far better than fighting it yourself.
Get an itemized invoice. Removal, debris hauling, and any tarping or temporary repair listed separately, with a cause note. Adjusters move quickly on clean paperwork.
Overhanging branches: the self-help rule
Different situation, different rule. Branches or roots crossing onto your property are yours to cut — back to the property line, at your own expense. You cannot enter their yard to do it, and you cannot cut so aggressively that you kill or destabilize the tree. That last part is not a technicality: Maryland allows substantial damages for wrongful destruction of a tree, and "I was only trimming my side" is not a defense if the tree dies.
Practical advice: for anything larger than a few limbs you can reach from a ladder, have it done professionally and have the cut line documented. A proper reduction cut at the line protects both the tree and you.
A note on staying neighbors
Most of these situations resolve without anyone involving a lawyer, and the ones that go badly usually went badly on tone before they went badly on law. Leading with a shared quote — "I had someone look at it, here's what they found, want to split it?" — works far more often than leading with liability. A hazardous tree removed cooperatively costs both of you less than the same tree removed after it lands on something.
