Send your lawyer a letter requiring signature verification returned to you requesting your entire file. It is YOUR information. He has no right to keep it. If you don't get a response, go to the attorney registration/ disciplinary committee or state bar association in your state with a complaint in written form that you've been denied your legal and medical files. Your lawyer will either comply, or face discipline.
