The ABA Model Rules of Professional Conduct have not been updated to address the use of AI specifically. That said, it’s likely that Rule 7.1: Communications Concerning a Lawyer’s Services will apply. Under that rule, a lawyer cannot make false or misleading statements, and a communication is false or misleading if it contains a material misrepresentation of fact or law, or omits a fact necessary to make the statement considered as a whole not materially misleading. Comment 2 to Rule 7.1 states that “[a] truthful statement is misleading if a substantial likelihood exists that it will lead a reasonable person to formulate a specific conclusion about the lawyer or the lawyer’s services for which there is no reasonable factual foundation.” This comment could be interpreted to mean that if readers base their opinion of an attorney’s knowledge or skill based on AI-generated content, it would violate the rule. Also, as with untrained human-generated content, AI-generated content may contain statements that violate more specific rules, such as those regarding calling yourself an “expert” or “specialist” in a given area of law.
