A boundary line agreement is a legally binding document that sets clear boundaries between neighboring properties, providing certainty and preventing conflicts.

Boundary treaties are treaties, but are distinctive. They constitute a special. category of treaties. Boundary treaties may constitute a root of title to territory. and, as such, will have widespread effect within the international community.
Under such an agreement, the parties acknowledge the true boundary line between the properties, and the encroaching owner releases any claim to the strip of land encroached upon.

Boundary lines help determine the extent of a property and its legal ownership. Specifically, these lines define a property's physical limits and help prevent conflicts between neighboring property owners.
