Do I have to stay with the attorney who represents me?
The short answer the your question is no, you do not. Typically most clients are represented on a contingency fee basis. However, some may pay hourly. Regardless of the financial arrangement, clients have the right to switch attorneys as they see fit. It's just an issue of public policy. If a client isn't happy with the attorney they've hired they absolutely have the right to switch attorneys at any point during the proceedings.
