What is a monument in legal terms?

A monument, in legal terms, is defined as a permanent land marker that is used in legal descriptions of property. This can include physical markers such as stones, stakes, or other established landmarks that are used to delineate the boundaries of a parcel of land. Monuments play an essential role in defining property lines and aiding in boundary surveys, making them critical in the field of real estate and property law.

The other choices represent different concepts related to land but do not capture the legal definition of a monument. For instance, 43,560 square feet refers to an acre, which is a unit of area measurement rather than a physical marker. A point from which elevations are measured relates to benchmarks or reference points used in surveying for vertical measurements, rather than boundary identification. Finally, the subdivision of air above the land pertains to air rights and does not pertain to the concept of physically marking land boundaries. Therefore, the identification of a monument as a permanent land marker used in legal descriptions is accurate and highlights its important role in property delineation.
