If you have an account with an investment advisory firm, you are generally required to bring claims for losses to arbitration conducted by either AAA (American Arbitration Association) or JAMS (Judicial Arbitration and Mediation Services). Customer disputes that are filed with AAA or JAMS may be heard by one to three arbitrators. AAA and JAMS have their own procedural rules, but the decision of one of these arbitration panels is ordinarily final and cannot be appealed. Claims against insurance companies, issuers of securities, and others sometimes can be filed in a court of law.
