First, contact your state Bar Association: many state bar associations will help resolve monetary disputes between attorneys and their clients. If that does not satisfactorily resolve the situation, you could sue your attorney to recover any amounts which he should have turned over to you but did not; an attorney is only entitled to keep that amount of the settlement which you had, in engaging his representation, specifically agreed to pay him. The agreement (whether written or oral/verbal) between you and your attorney as to his representation of you is as enforceable as any other contract.
