What can be done if he is trying to double charge?

You are entitled to your entire file from the attorney and point out to them that you have that right under the State Bar rules. Demand that you get the entire file, including his notes and papers showing what happened to the money involved. ?At that point you can then re-post your question with the facts of the case. Be sure to state the facts clearly, as your current post is not clear [were you the care giver, what was the basis of the suit, what do you think was double billed, what does your contract with the attorney say about that, etc.
