Most states use Promulgated Contracts which are made by attorneys and the Real Estate Commission in the state to be used by licensed real estate agents. Often times the transaction goes smoothly and attorneys would not get involved. However, if you feel as though you would be more comfortable having an attorney review the contract and addenda, and also go over it with you...you always have that right. I tell all of my clients. If there is something here that you do not understand, please consult an attorney. Just because it is not typical, does not mean you can't or should not use one. Good luck.
