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 New Jersey, attorney and law firm advertising is governed by the New Jersey Rules of Professional Conduct, specifically Rule 7.1, which addresses communications concerning a lawyer's services. These rules are enforced by the New Jersey State Bar Association. The regulations require that all attorney advertisements must be truthful and not misleading, and they must not make comparisons with other lawyers' services unless they can be factually substantiated. Attorneys must also refrain from making any guarantees about the outcome of a case. Specific disclosures may be required in the advertisement to avoid any potential deception. For example, if an advertisement includes a dramatization, it must be clearly indicated. The use of testimonials or endorsements is permitted but comes with certain restrictions to ensure they are not misleading. Additionally, any advertisement must be kept for a period of at least three years after its last dissemination along with a record of where and when it was used. These rules apply to all forms of advertising, including television, radio, social media, print, billboards, and other mediums.
