Summary
The article analyses the effect of AI on the business model of law firms. A trained AI can analyse a 50-page contract in 30 seconds, compared with three hours for a junior associate. According to the author, this automation breaks the link between time spent and value billed, making the billable hour model obsolete. Corporate legal departments are said to now refuse to pay for learning time or basic research, demanding results and informed risk-taking. The article distinguishes between firms that remain attached to the billable hour, and face eroding margins, and those that shift to fixed fees, subscriptions or success-based premiums, which may achieve higher profitability. The author calls for a commercial and managerial transformation, not just a technological one.
