A legal boundary is an invisible legal line that denotes the extent of land ownership. In most instances this invisible legal line runs along a physical feature, like a fence, wall or hedge. However, this is not always the case, and sometimes there is no physical feature on the ground or features have been moved – such as a fence blowing over and then being re-erected in a different location. In addition, further boundaries are created when a landowner sub-divides his land into smaller pieces or parcels of land. The boundary survey establishes the perimeter of a property as it relates to a site’s legal description. It reestablishes and/or recovers the property corners of a piece of property and accurately defines the limits of the subject property.
