Law must be precise. A vast number of legal communications are standard form contracts or letters which only require the insertion of the particular client details. There can be serious adverse consequences if these lack accuracy and consistency in any respect. For instance, inadvertently using the wrong middle initial of a name, or misplacing a digit in a house number could be a cause of future dispute. Consequently, careful proofreading of legal documents is an essential, although often, tedious, task.
