Attorney and law firm advertising involves legal ethics standards and is regulated by the state bar associations in which the attorney is licensed, or in which the advertisements appear. The disclosures and required and prohibited advertising content varies from state to state, whether the advertisements appear on television, radio, social media, print, billboards, or another medium.

In Tennessee, attorney and law firm advertising is governed by the Tennessee Rules of Professional Conduct, specifically Rule 7.1 through 7.5, which address communications concerning a lawyer's services, advertising, and solicitation. These rules mandate that any communication about a lawyer or law firm's services must be truthful and not misleading. Attorneys are prohibited from making false or unsubstantiated comparisons of their services or suggesting that they can achieve results by means that violate the Rules of Professional Conduct or other law. Disclosures may be required to clarify the context of an advertisement and to avoid any potential deception. For example, if an advertisement includes actors, there must be a disclosure informing the viewer of this fact. The use of testimonials or endorsements is permitted, but they must be accompanied by disclaimers if they are not representative of all clients' experiences. The Tennessee Supreme Court through its Board of Professional Responsibility oversees the enforcement of these rules. Attorneys must also comply with any applicable federal regulations, such as those from the Federal Trade Commission (FTC) regarding truth in advertising.
