Definition from Nolo’s Plain-English Law Dictionary
From an old term meaning measures and directions, a method of coming up with a "legal description" of a parcel of real estate that is much more precise than a street address or parcel number. The description exactly describes the perimeter of the property,using carefully measured distances, angles, and directions. The description must start at an identifiable point and end there as well. It is recorded in the county land records office in the county where the property is located.
