Boundary Line Trees in Minnesota: Who Owns the Tree on the Property Line?

A tree whose trunk sits on the boundary is a different legal animal than a tree that merely leans over it.

General information for Minnesota homeowners, not legal advice.

Shared trunk, shared tree

The widely applied rule is that a tree with its trunk standing partly on each side of the boundary is owned in common by both property owners. The practical consequences are big:

• Neither owner may remove it unilaterally. Cutting down a boundary tree without your neighbor's consent exposes you to liability for their share of its value, which courts can assess at a meaningful number for a mature shade tree.
• Neither may damage it. Topping it, poisoning it, or trenching through its root plate all count.
• Both may generally maintain their side with proper pruning that doesn't harm the tree.
• Costs are usually shared by agreement. There is no automatic split, which is why written agreement matters.

Where the trunk is measured matters

Owners argue over "it's mostly on my side." The location that matters is where the trunk stands at ground level, not where the canopy sits or where the branches lean. A tree planted three feet inside your neighbor's line that has grown a wide flare touching the boundary is generally still their tree.

If it's genuinely close, get a survey before anyone touches it. A surveyor is a few hundred dollars. A destroyed-tree claim is not.

Getting a shared tree removed

When a boundary tree is dead, hazardous or has to come out for a project, do it in this order:

1. Confirm ownership with a survey if there's any question.
2. Get an arborist's written assessment of the tree's condition. A documented hazard makes the conversation far easier and gives a reluctant neighbor a reason that isn't "because I want to."
3. Agree in writing on the scope, the contractor, who's paying what, and what happens to the stump. Simple and signed beats vague and friendly.
4. Check the city. Some metro cities regulate removal of significant trees, and if any part of the tree is in the boulevard, it belongs to the city entirely.
5. Use one insured contractor for the whole job. Two crews and two invoices creates disputes about who damaged what.

If the neighbor refuses and the tree is genuinely hazardous, put your concern in writing with photos and an arborist's report, and keep the copy. That documentation is what shifts responsibility if it later fails. Our step-by-step: documenting a dangerous neighbor tree.

Fence lines are not property lines

Worth repeating, because it causes half of these disputes: the existing fence may have been set inside the line, outside it, or by eyeball in 1974. Most metro cities require a site plan showing the actual property line when you permit a new fence — see our permit guides by city — and that is often the moment homeowners discover where the line really is.

We work both sides of the line

We regularly do boundary-tree work with both neighbors on the same written scope and a split invoice, so nobody is guessing. Free assessment anywhere in the Twin Cities metro: 612-400-8036.
