What ABA Formal Opinion 512 says
ABA Formal Opinion 512 discusses competence, confidentiality, client communication, and supervision. The opinion also covers candor toward the tribunal and fees. Its confidentiality analysis is fact-driven and depends on the client, the matter, the task and the GAI tool. The opinion requires informed client consent before a lawyer inputs information relating to the representation into a self-learning GAI tool. It states that boilerplate engagement-letter language does not provide sufficient informed consent.
Local execution does not replace that assessment.
