What are They? An easement is a permanent right of one person to use another’s real estate for some specific use. The area covered by the easement is typically a portion of a property, the area of which is calculated by a surveyor and depicted on a recorded document that creates it. The easement boundaries are defined as to length, width, and if necessary height or depth. Once recorded, the easement is discoverable and will show on a commitment for title insurance and a survey. Since they can be good or bad for the affected landowners, they should be scrutinized carefully when you are buying a property. Next: Types of Easements.
