Lately, I have seen a number of minor document errors create major headaches for my clients. A simple inversion of 2 digits on a Deed can create hours of work and hundreds of dollars in additional filing fees to correct. It is important that you make sure that whoever is preparing your legal documents takes the time to review and double check everything carefully. Additionally, the client should check things over themselves to prevent typos that can create future problems.
While the client is not responsible for the legalese, the client can at least check the spelling of names and proper addresses inserted into the documents as errors are made very commonly, especially once a misstatement gets inserted into a computer.
