What is a 'designated broker' and why is the role critical?

DESIGNATED BROKER (also called Principal Broker, Managing Broker, or Responsible Broker depending on the state) is the individual who: holds the brokerage licence; bears legal responsibility for all licencees operating under their licence; is personally responsible for trust account maintenance and reconciliation; must supervise salespersons and ensure they comply with state law; is the named responsible party in any brokerage disciplinary action. If a salesperson under their supervision violates fair housing, mishandles client funds, or engages in fraud, the designated broker can face their own disciplinary action under their supervisory responsibility. This is why the broker's supervision of agents is a fiduciary obligation — not just an administrative one.
