⚠️ Important: This article explains general Tennessee tree law principles. For specific legal advice about your situation, consult a Tennessee attorney. We're tree pros, not lawyers.
Few things create more neighborhood drama than a tree near a property line. Whose tree is it? Who pays when branches damage your house? Can you cut limbs that overhang your yard? Here's how Tennessee tree law actually works for Knoxville homeowners.
The Basic Rule: Where the Trunk Sits Determines Ownership
Under Tennessee law, the location of the tree's trunk determines who owns it. Not the canopy, not the roots — the trunk.
- If the trunk is 100% on your side of the property line, the tree is yours.
- If the trunk is 100% on your neighbor's side, the tree is theirs.
- If the trunk straddles the line ("boundary tree"), you both own it jointly — and both have legal responsibility.
This matters because tree ownership determines who's responsible for maintenance and who pays for damage.
Can I Trim Branches That Overhang My Property?
Yes, with limits. Tennessee follows the "self-help" rule: you can trim branches and roots from a neighbor's tree that extend onto your property — but only up to the property line.
What you can do:
- Cut branches and roots back to the property line
- Hire a tree service to do it for you
- Keep or dispose of the cut material
What you can't do:
- Enter your neighbor's property without permission
- Cut beyond the property line
- Damage the tree's health (over-pruning that kills the tree can make you liable for its value — sometimes thousands of dollars)
- Cut without notifying your neighbor first (this is best practice, not strictly required)
Who Pays When a Neighbor's Tree Falls on My House?
This is the most contentious question — and the answer often surprises people. Generally, your insurance pays — not your neighbor's.
Tennessee follows the "act of nature" rule for tree damage:
- If a healthy tree falls during a storm or natural event, the tree owner is typically NOT liable. Damage = "act of God." Your homeowner's insurance handles your damage.
- If the tree was visibly dead, decaying, or hazardous, and the owner knew (or reasonably should have known), they CAN be liable. This is "negligence."
How to Establish Negligence (And Make Your Neighbor Pay)
If you suspect a neighbor's tree is hazardous and likely to damage your property, document it now:
- Take dated photos of the tree showing visible signs of decay (dead branches, conks/mushrooms, leaning, cracks)
- Send a written notice (text, email, or certified letter) telling them you believe the tree is hazardous and requesting they have it inspected or removed
- Get an arborist assessment if possible — a written report from a tree professional documenting the hazard
- Save everything
If the tree later falls on your property, this paper trail can shift liability to your neighbor.
What If My Neighbor's Tree Roots Damaged My Foundation or Sewer Line?
Root damage is treated similarly to branch damage. You're generally allowed to cut roots that cross onto your property — up to the property line. If the roots damaged your house or sewer line, your insurance likely covers it.
Exception: if your neighbor planted the tree recently and clearly should have known the species would damage neighboring property (some species like Silver Maple are notorious for invasive roots), there may be a case for liability.
What About Trees in Easements or Right-of-Ways?
Many Knoxville properties have utility easements where KUB or another utility has the right to maintain trees that interfere with infrastructure. If a tree on your property threatens a power line, KUB may trim or remove it — usually at no cost to you. But the tree itself is still yours, and you're still responsible for the rest of its maintenance.
The Knoxville Reality Check
Most tree disputes between neighbors are NOT worth pursuing legally. By the time you've paid a Tennessee attorney to file suit, the tree work could have been done many times over. Better path:
- Talk to your neighbor first — most are reasonable when approached politely
- Get an arborist's opinion — neutral third party
- Split the cost if it's truly a shared concern
- Document everything in case mediation fails
