The Lawyer's Duty of Technology Competence and AI

ABA Model Rule 1.1 requires competent representation; Comment 8 says lawyers should keep abreast of changes in law and practice, including benefits and risks associated with relevant technology. The ABA’s 2024 Formal Opinion 512 applies existing professional duties to generative AI, including competence, confidentiality, communication, supervision, candor, and fees. The opinion is guidance based on the ABA Model Rules; states adopt and interpret professional rules differently. Competence does not mean that every lawyer must use a particular AI product or become a machine-learning engineer. A lawyer should understand enough about a tool to decide whether it fits the task, what data it receives, how its output may fail, and what review is necessary. Generated legal research can contain nonexistent cases, false quotations, stale law, or unsupported summaries. A citation that looks plausible still needs to be checked against the actual authority and current law. Before relying on output, identify the task, governing jurisdiction, source material, tool limits, and consequences of error. Review facts, authorities, calculations, and drafting; supervise staff or vendors who use AI; and document important decisions. Consider privacy and client communication duties before entering information into a service. The required level of review depends on the task and risk.
