What is a Land Title Survey?  If you are purchasing title insurance, often a land title survey is required. This is usually a boundary retracement survey with additional surveying to meet the specific needs required by title insurance companies. The map of such a survey must show particular information in detail and exactness of matters discoverable from survey and inspection, and not necessarily evidenced by public records. Unrecorded easements, access roads to other properties, physical encroachments of buildings and other visible adverse uses of the property by other parties are examples of matters of particular concern for a land title survey.
