A survey is a legal document prepared by a licensed surveyor that defines the exact boundary, size and features of a tract of land. It can be used to determine the exact dimensions of the tract of land that is being transferred from one party to another. A survey drawing will show property corners, adjacent tracts, easements or any other encumbrances, existing physical features such as buildings or fences, and the exact area of the tract. When preparing a survey, the surveyor will visit the site to find property corners and other physical features. They will take precise measurements of the location of everything to be shown on the drawing. Additionally, they will visit the courthouse or receive a title report that shows all easements and other legal instruments that affect the tract. Once the information is gathered, they will prepare the drawing that clearly shows all of the information so that the buyer and seller can clearly review what is being transferred.
