What is a managing broker's responsibility if a salesperson under their supervision violates a real estate law?

Managing brokers bear vicarious responsibility for the conduct of licensees under their supervision. 'Failure to supervise' is itself a violation, separate from the licensee's underlying violation. Reasonable supervision typically requires: (1) Training new licensees on real estate law, fair housing, agency, ethics, contract requirements; (2) Reviewing contracts and significant transaction documents; (3) Maintaining policies and procedures that direct licensees to compliance; (4) Being available to answer questions and address issues; (5) Investigating complaints promptly; (6) Taking corrective action when violations are identified. Managing brokers cannot delegate this responsibility to others or use 'I didn't know' as a defense — they are expected to have systems in place that detect and prevent violations. Penalties for failure to supervise can include fines, license suspension, or revocation. The managing broker faces these penalties in addition to whatever penalties the violating licensee faces. This vicarious responsibility is a key reason brokerages establish written policies, regular training programs, and review procedures.
