What does most state law require regarding a licensee's advertising of a property or services?

State advertising rules commonly require that a licensee's advertising — including yard signs, print, websites, and social media — be truthful and not misleading, and that it disclose the name of the brokerage under which the licensee operates. This 'blind ad' prohibition prevents consumers from being misled into thinking they are dealing with a private party or an unaffiliated agent. Some states add requirements about how a team or franchise name may appear, or about disclosing the licensee's status. The details differ by state, but the core principles — honesty, no misleading claims, and identification of the responsible brokerage — appear across the state portion.
