Easements encumber a space that gives others a legal right to use, cross or access another space for a specific purpose without having to title ownership of the land. This is common among utility companies for running and maintaining utility lines. Easements may be for driveways, pathways, encroachments, or various other needs. Easements can even be spaces of air with vertical and horizontal limits. It's important to know the location of easement boundary lines as they may affect what rights you or others may have to the specific space defined within the easement.
