A back title letter is a document given by a title insurance company to an attorney representing a buyer or seller that describes the history of the title. They are used legally to give the condition of a title, and the title is usually handled by a reliable examiner before a formal letter is released to the attorney. At this point, the attorney is expected to examine the title for whatever legal reasons are deemed necessary by the buyer or seller. Back title letters usually go back to a very specific date but can include the entire recorded history of the title. One of the main purposes of title insurance is to prevent any future issues that may come up due to defects in the title, and the back title letter could be considered a formal legal response for the attorney to examine.
