The legal description of your property appears on your deed. Do not use the legal description from your tax statement as that is an abbreviated version and does not contain the complete legal description.
Simple Concise Legal Description May Not Exist
While this seems simple enough, it can be complicated by two factors. If your property consists of a number of small parcels that have been combined over time, a simple concise legal description may not exist. The opposite can also be a problem. Your property may have previously been a large parcel from which smaller parcels were sold off. In both of these cases, several documents and some interpretation may be required to construct a legal description.
If the history of your parcel fits into either of the above descriptions, you should contact a professional land surveyor for additional assistance in writing an accurate, updated legal description.
