What is a point of beginning in a metes and bounds description?

The point of beginning is the fixed, identifiable starting point from which a metes and bounds property description begins and to which it must return to create a closed boundary. It must be a permanent, identifiable landmark or monument such as an iron pin, a concrete marker, or the intersection of two roads. If the point of beginning is vague or impermanent, the entire legal description may be challenged as invalid. The point is typically described by its relationship to a known reference like a section corner, a road intersection, or a recorded monument from a prior survey.
