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 Indiana, attorney and law firm advertising is governed by the Indiana Rules of Professional Conduct, specifically Rule 7.1 - 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 with other lawyers' services. They must also refrain from implying that they can achieve results by means that violate the Rules of Professional Conduct or other law. Any advertisement must include the name and office address of at least one lawyer or law firm responsible for its content. Solicitation of clients is subject to strict rules, particularly when directed to someone who has not sought the lawyer's advice or with whom the lawyer has no family or prior professional relationship. The Indiana State Bar Association provides guidance and may review advertisements for compliance. Violations of these advertising rules can result in disciplinary action by the Indiana Supreme Court Disciplinary Commission.
