Which legal description does not require a reference to a physical monument?

A legal description that does not require a reference to a physical monument is the Lot and Block system. This method is commonly used in urban or suburban planning and involves dividing land into lots or blocks that are recorded in a plat map. It typically references a specific subdivision and provides clear identifiers like lot numbers and block designations, rather than physical landmarks or monuments.

In contrast, the Metes and Bounds system relies heavily on physical monuments and specific measurements (metes and bounds) to define the boundaries of a parcel of land. This method involves using natural landmarks, man-made structures, and angles or distances.

The Rectangular Survey system, also known as the Public Land Survey System, involves the division of land into townships and sections and refers to specific government-monitored points rather than physical monuments.

The Geo-Coordinated Description method, which is based on exact coordinates provided by global positioning systems (GPS), offers a precise location without necessitating physical markers, but typically relates to an exact aerial location rather than traditional markers.

Thus, the Lot and Block system stands out as the approach that can function without the need for referencing physical monuments.
