An easement is a legal right to use someone else s land for a particular purpose.
Easements are part and parcel of the land they affect.
They don t change when the property changes hands. Subsequent owners are obliged to let whoever owns the easement use the property. Whoever owns the property may not interfere with the purpose of a legal easement. A property owner who does interfere with an easement can be liable to the easement owner for any damage he causes. The most common kind of easement is one given to a utility company or a city.
