Who is responsible for a tree on the property line?

Property-line trees cause more arguments than almost anything else in a yard. The rules depend on your state and sometimes your city, so use this as a starting point only.

A common idea is that a tree belongs to the person whose land the trunk grows from. If the trunk is clearly on one side, that owner is often responsible for its care and for harm it causes. If the trunk sits on the line, both owners may share it, and neither one should cut it down without the other agreeing.

Roots and branches that cross the line are a separate matter. Many places let a neighbor trim branches back to the property line, but not in a way that kills or badly harms the tree. Rules differ, so check before you cut.

If you are not sure where the line is, a property survey can show it. Your county records office may also have a plat map.

Before any work, talk to your neighbor. Show them the problem, offer to share the cost of an inspection, and write down what you both agree. When a tree company comes, tell it that the tree is on a boundary so it can quote properly.

For arguments that do not settle, ask a local lawyer. This is a short explanation, not legal advice.
