What is a reasonable practice for a broker to supervise the advertising done by affiliated agents?

Advertising is an area where the broker's supervisory duty is clearly tested. Agents' advertising must typically include the brokerage's name (so the public knows the agent works under a broker), must be truthful and not misleading, and must comply with fair-housing rules and any state-specific disclosure requirements. A reasonable broker reviews or sets clear standards for agent advertising — including signs, online listings, and social media — and corrects problems. Because the brokerage can be held responsible for an agent's misleading or discriminatory ad, having a review process and written advertising policy is a practical way the broker meets the duty to supervise.
