I hired an attorney to represent me against two auto insurance companies. Later I found out that his firm also has represented these same two companies. Wasn't the attorney legally and morally obligated to tell me this? I would not have hired him if I had known.
You are raising issues regarding conflict of interests. These issues are often difficult; more gray areas than black and white areas. You may consider getting copies of your files and then meeting with another local lawyer to discuss your cases.
