Verify at FINRA BrokerCheck
FINRA BrokerCheck provides the full official disciplinary record, including individual registered advisors. Always verify before hiring a financial advisor.
Every firm registered with FINRA or the SEC must report regulatory actions, customer
complaints, arbitrations, and civil judicial events on its public BrokerCheck and Form ADV
records. A disclosure is not automatically a finding of wrongdoing, it can range from a
settled customer dispute to a formal regulatory sanction, but a heavy disclosure load
relative to a firm's size is a signal worth examining before you hire. Because larger firms
naturally accumulate more disclosures across more offices, PlainAdvisorCheck grades each firm
against same-size peers rather than on raw counts. Read each disclosure's underlying detail on
the official record rather than relying on the headline number alone. Registration itself
confirms only that a firm is authorized to do business, not that its compliance history is clean.
