To Report a Complaint Against FINRA Member Firms or Associated Persons
Investors, issuers or others with complaints against securities firms, individuals associated with securities firms or municipal advisors that are registered with the Financial Industry Regulatory Authority (FINRA) may use FINRA's Investor Complaint Center. If you are unsure whether the firm is a FINRA member, you may check the MSRB’s registered dealer list or registered municipal advisor list. If the MSRB number starts with the letter “A,” the firm is registered with FINRA.

An investor who has a dispute with such a firm or individual may be able to file a claim for monetary damages with FINRA's arbitration program. For information about filing such a claim, visit FINRA's Arbitration and Mediation webpage.

To research the complaint history and professional background of a securities firm or associated individual, use FINRA's BrokerCheck website.
