Customer Complaint Process (FINRA)
The FINRA customer complaint process is the formal mechanism through which retail and institutional investors submit written complaints against FINRA-member broker-dealers and their registered representatives, triggering FINRA's supervisory and enforcement review of the alleged misconduct and providing a record that informs regulatory examinations, enforcement investigations, and public disclosure through BrokerCheck.
When an investor believes a broker-dealer or registered representative has acted improperly — through unauthorized trading, misrepresentation, unsuitable recommendations, excessive fees, or other misconduct — FINRA provides multiple channels for raising those concerns. Understanding the process is essential for investors seeking redress or regulatory action.
The most direct avenue is submitting a complaint through FINRA's online complaint center at finra.org. Complaints should be submitted in writing and should include the name and CRD number (if known) of the broker or firm, a description of the transactions or conduct at issue, the approximate dates of the events, and any supporting documentation such as account statements, trade confirmations, or written communications.
FINRA's Office of the Investor Advocate and regional examination teams review incoming complaints to assess whether they warrant a regulatory response. Complaints that allege violations of FINRA rules or federal securities laws may trigger examination requests, referrals to FINRA's enforcement department, or other regulatory action. However, FINRA does not act as an advocate for the individual complainant — its regulatory mission is to protect the investing public broadly, not to recover money for specific investors.
FINRA is required to reflect customer complaints in BrokerCheck, the public disclosure system that provides information about registered broker-dealers and their associated persons. A complaint that is not subsequently resolved in the broker's favor is publicly disclosed on BrokerCheck, where investors can review it when evaluating whether to do business with a particular firm or individual. This public disclosure function creates reputational consequences for brokers that accumulate complaint histories, independent of any formal regulatory action.
For investors seeking to recover losses rather than simply triggering regulatory review, FINRA arbitration is the primary dispute resolution mechanism. Most customer brokerage agreements contain mandatory arbitration clauses requiring that disputes be resolved through the FINRA arbitration forum rather than through court litigation. Filing a complaint with FINRA and pursuing arbitration are independent processes that can proceed simultaneously.
State securities regulators — organized as members of the North American Securities Administrators Association (NASAA) — also accept investor complaints and have independent authority to investigate and bring enforcement actions against broker-dealers and investment advisers operating in their jurisdictions. Filing parallel complaints with FINRA and the relevant state regulator maximizes regulatory pressure and can accelerate resolution.
