The Financial Industry Regulatory Authority (FINRA) provides rules, standards, and practices for securities brokers. One of its most notable rules is Rule 12200, which governs all disputes related to the business activities of securities brokers. The rule provides that a dispute between a securities broker and an investor must proceed to arbitration if the broker and the investor agree to arbitration, or if the investor requests it. Other FINRA rules define arbitration procedures, including the selection of arbitrators and the structure of hearings. Decisions in FINRA arbitration are usually final and binding.
