Law in the Era of AI: Clients, Firms, and the Future of the Legal Industry argues that corporate legal departments, not technology vendors, will drive the most profound disruption of traditional law firms. As generative AI transforms how companies operate, in-house legal teams must revise their service models, creating client-side pressures that will reshape legal service delivery from the outside in. Drawing on three decades of firsthand experience leading digital transformation at major corporations, veteran General Counsel Bjarne P. Tellmann examines why the billable hour and pyramid structure model are increasingly misaligned with the demands of AI-enabled clients. As companies evolve into "AI factories," legal work is being reorganised around automation, data, and new forms of human judgment. Tellmann explores the emerging models now taking shape - from marketplace platforms and Big Four-inspired organizations to new corporate approaches to law firm structure - and outlines strategic pathways legal service providers can pursue to adapt before disruption arrives. Essential reading for leaders of in-house legal teams, law firm leadership, and alternative legal service providers, this book delivers a rare client-centric perspective and practical guidance for navigating the changes ahead. A timely and provocative guide to the future of legal services, Law in the Era of AI shows how client transformation, not firm tradition, will define the next era of the profession. Drawing on disruption theory, Tellmann offers a strategic roadmap for legal departments, law firms, and new providers seeking to remain relevant as AI reshapes corporate decision-making, risk, and the delivery of legal work.
