While no particular organization publishes complaints against law firms, each state has an organization dedicated to reviewing and investigating such complaints. In some cases the state's bar association handles these complaints, and in others the court system's disciplinary board is in charge of them, as FindLaw explains.
Procedures for responding to complaints about attorneys vary slightly from state to state. Generally a board reviews every complaint received and decides whether it merits further investigation. If the board upholds the complaint, it has the option to fine the attorney, to take away his license to practice law, to require him to attend classes, or to sentence him to community service, according to FindLaw.
