Under Florida boundary tree law, a tree whose trunk crosses the property line is jointly owned by both neighbors, and neither one can remove it or significantly alter it without the other’s consent. Routine pruning on your own side is fine. Cutting the tree down, poisoning it, or doing anything that compromises its structural integrity is not, and doing it anyway can cost you thousands of dollars in damages.
The Trunk Rule Decides Ownership
Florida uses one rule to sort out who owns a tree: look at the trunk. If the trunk sits entirely on your land, the tree is yours, even if branches sprawl across the fence and roots run under your neighbor’s driveway. Ownership brings the duty to maintain the tree and liability if you don’t.
When any part of the trunk crosses the property line, the tree becomes a boundary tree and both neighbors share ownership equally. This catches people off guard, because a tree can look like it belongs almost entirely to one yard while still qualifying as jointly owned. The visual impression doesn’t matter. The trunk’s position does.
What Shared Ownership Actually Means
Joint ownership means joint decision-making on anything that affects the tree as a whole. You can prune what hangs over your side. You cannot remove the tree, poison it, or take actions that compromise its health or structure without your co-owner’s agreement.
In Elowsky v. Gulf Power Co., a Florida court awarded damages when a boundary tree that provided shade was removed without the co-owner’s permission. The court recognized the value the tree contributed to the property owner’s comfort and property value, not just the cost of replacing it.
That valuation matters, because unauthorized removal of a mature boundary tree can be expensive. Species like live oaks are often appraised at thousands or tens of thousands of dollars once you account for replacement cost, lost property value, shade and energy savings, and stormwater management benefits. Courts can award damages reflecting what the neighborhood lost, not just what a new sapling would cost to plant.
If you and a neighbor disagree about what to do with a shared tree, the safest step is to hire a certified arborist together and get a written recommendation before anyone touches the tree. Written consent from your co-owner before any major work is what keeps a disagreement from becoming a lawsuit.
Trimming Your Side of the Line
Florida common law gives every property owner a “self-help” right to trim branches or roots back to the property line without asking permission and without going to court. The person doing the trimming pays for it. In Scott v. McCarty, a Florida court reaffirmed that landowners handle encroaching vegetation on their own side at their own expense.
The right has real limits, and they matter more for a boundary tree than for a tree owned entirely by your neighbor. You can only cut what’s on your side of the line. You cannot enter the co-owner’s yard, and you cannot trim so aggressively that you kill the tree or destroy its structural integrity. If overzealous pruning causes a shared tree to die or become hazardous, you can end up liable for its full value. A useful test: if removing the encroaching branches would require cutting a major limb back to the trunk on the co-owner’s side, stop and get professional guidance first.
Florida law doesn’t require you to notify a neighbor before trimming your side, but a short conversation prevents most disputes. It also gives you a chance to find out whether a local ordinance protects the tree before you start cutting.
Who Pays When a Boundary Tree Falls
Storm damage liability turns on whether the tree was healthy. When a sound, well-maintained tree falls during a hurricane or severe storm, Florida courts treat the event as an “Act of God.” The tree’s owner or owners bear no liability, and whoever’s property was damaged pays for cleanup and repairs. Many Florida homeowners assume the neighbor with the tree should pay. Under current law, that’s not how it works.
Liability shifts when the tree’s owner knew or should have known the tree was dangerous. A dead tree, a trunk riddled with fungal decay, a major limb hanging at a dangerous angle — those conditions create a duty to act. Ignore them, and the owner can be held liable for the resulting damage because it was foreseeable and preventable.
“Should have known” does most of the work in that sentence. You don’t get a pass because you never looked at the tree. If a reasonable homeowner would have noticed the problem, a court can find you negligent whether or not you actually saw it.
For a boundary tree, both co-owners share the maintenance duty, which means both can share the exposure if the tree fails from neglect. If you’re worried about a shared tree, get a written assessment from an ISA-certified arborist and send your co-owner a copy by certified mail. That paper trail is difficult to dispute later, and it puts the other owner on formal notice.
A Florida Senate bill known as the Fallen Tree Act would have made tree owners liable for storm damage regardless of the tree’s health. It died in the Banking and Insurance Committee during the 2025 legislative session, so the traditional rule still applies.
Removing a Hazardous Boundary Tree
Many Florida municipalities require permits before you can remove a residential tree above a certain trunk diameter. Heritage trees, specimen trees, and certain native species often carry extra protection under local ordinances, and unauthorized removal can bring steep fines and mandatory replacement plantings. Orange County, for example, requires replacement trees totaling five times the trunk diameter of a removed heritage tree.
Florida Statute 163.045 creates an important exception. If a tree on residential property poses an unacceptable risk to people or property, your local government cannot require a permit, application, fee, or mitigation for removing it, provided you have documentation from an ISA-certified arborist or a Florida-licensed landscape architect confirming the risk. Under the statute, “unacceptable risk” means removal is the only practical way to bring the tree’s risk level below moderate, based on industry-standard tree risk assessment procedures. The local government also cannot force you to replant.1The Florida Legislature. Florida Statutes 163.045 – Tree Pruning, Trimming, or Removal on Residential Property
None of that overrides the joint-ownership rule. Statute 163.045 removes the local permitting barrier when a tree is genuinely hazardous. It doesn’t authorize you to remove a boundary tree over your co-owner’s objection. Before removing a shared tree even for safety reasons, get the arborist’s written assessment, share it with your co-owner, and get consent in writing.
Insurance When a Shared Tree Causes Damage
When a healthy boundary tree falls on your house during a storm, you file the claim on your own homeowners insurance, not your neighbor’s. Dwelling coverage typically pays for structural repairs, and your policy may include some allowance for debris removal, though that amount is often capped and may not cover removing a large tree.
The calculus changes if the co-owner ignored a known hazard. If you notified your neighbor in writing that a shared tree was dead or dangerous, and they did nothing, their homeowners liability coverage may be on the hook. This is where the certified-mail arborist report pays for itself, because it establishes the notice that insurers and courts rely on when assigning fault.
If a tree falls in your yard without hitting a structure, most standard policies won’t cover removal at all. Hurricane season makes this a common surprise. It’s worth checking your policy’s debris removal sublimit before the next storm.
Settling a Boundary Tree Dispute
Most tree disputes never need a courtroom. A direct conversation resolves the majority of them. When it doesn’t, a few practical steps can keep the fight from consuming more than the tree is worth.
If the underlying disagreement is really about where the property line falls, a professional land survey settles it. Residential boundary surveys typically run several hundred to over a thousand dollars depending on lot size and complexity. That cost stings, but it eliminates the guesswork that fuels most boundary tree fights.
Mediation is often the most efficient next step. A neutral mediator helps both neighbors reach a written agreement without litigation costs. Many Florida counties operate dispute resolution centers that offer mediation at low or no cost for neighborhood conflicts.
When informal routes fail and the dispute involves quantifiable property damage, Florida’s small claims court handles claims up to $8,000, which covers most tree-related damage and removal cost disputes. Larger amounts go to county court and typically require an attorney, at which point the legal bill can outrun the tree’s value for all but the most serious cases. The neighbor who documented the problem early, communicated in writing, and got a professional arborist assessment starts every one of these fights in the strongest position.
