What term describes physical property that crosses into a neighboring landowner's property?

The term that describes a physical property that crosses into a neighboring landowner's property is encroachment. Encroachment occurs when a structure or other improvement, such as a fence, tree, or building, intrudes on a neighbor's land without permission. This can lead to disputes between neighboring property owners and can affect property values and rights.

Encroachment is significant in property law because it can result in legal action, such as an injunction to remove or modify the encroaching structure or a claim for damages. Understanding encroachment is crucial for property owners to ensure they respect their neighbors' property boundaries and to be aware of their rights in the event of an encroachment issue.
