From Shepard's to ChatGPT: Same Lesson, New Tool—Verify Everything

Generative AI has transformed legal practice, but it hasn't changed a lawyer's ethical responsibilities. In this episode, attorney Daniel J. Siegel traces the evolution of legal research from the days of Shepard's Citations to today's AI-powered tools like ChatGPT, Westlaw CoCounsel, and Lexis+ AI. The technology has changed dramatically, but one lesson remains constant: lawyers must verify everything before relying on it.Drawing on more than 40 years of practice, Dan examines recent court decisions sanctioning attorneys for AI-generated errors, explains why these cases are really about professional judgment rather than artificial intelligence, and discusses the continuing duties of competence, candor, and supervision under the Rules of Professional Conduct. He also offers practical steps every law firm should implement to use AI safely and ethically.Whether you're an experienced attorney, a new lawyer, or anyone interested in the intersection of law and technology, this episode provides a timely reminder that AI is a powerful assistant—but it is never a substitute for a lawyer's independent judgment.Topics discussed: The history of legal research—from Shepard's to AI  Why lawyers continue to be sanctioned for AI-generated errors  Lessons from recent cases, including United States v.
