One important consideration when selecting an attorney to represent you is conflict of interest. This principle holds that some pre-existing relationships should preclude a lawyer from taking a case. For example, few plaintiffs would want their attorney to be married to the person they are suing. How could the attorney possibly represent you to the best of his or her ability?
Most of the time, the relationship between a law firm and its clients is good. The attorneys work hard on behalf of the client. Win or lose, the client knows his or her lawyers did their best.
