In the process of purchasing a home, title revealed judgment that couldnt be paid lender denied loan seller/sellers attorney refuse to release deposit monies held in escrow my attorney has made calls and sent email letters in this regard. My attorney who was charging 1700 for a closing that obviously is not taking place says that I owe him money. How much is he allowed to charge for something like this. I have no retainer agreement or anything signed and have no idea what his fee will be because we were only quoted a closing fee. Is this ethical for him to charge and if so, what is a reasonable amount in an instance like this!
