AI Redefines the Billable Hour in Law Firms and In-House Legal Departments

AI Disrupts the Traditional Billing Model
Legal firms in the United Kingdom, Ireland, and the United States are seeing a shift in how productivity is measured. Among firms that have integrated AI, roughly 80 % say they can handle more work without adding resources, while over 70 % report cost reductions from automating administrative tasks. About one-in-five firms adopting AI find traditional billable-hour targets harder to meet, prompting experiments with credit-based billing.
Background & Context
The billable hour has long underpinned firm revenue and associate metrics. Recent AI deployments—such as A&O Shearman’s partnership with Harvey for contract review and Slaughter and May’s firm-wide rollout—have shortened routine document work. Deloitte’s survey of senior legal leaders projects the share of work charged by the hour will fall from 72 % to 44 % within two to three years.

What's Next
Law firms are expanding AI-credit programs, allowing associates to allocate part of their annual billing requirements to AI training. Several U.S. firms, including Akerman, already grant credit for AI-related projects that generate internal value. In-house departments anticipate hiring more data scientists, legal engineers, and AI-governance specialists to sustain rapid integration, while expecting a gradual reduction in reliance on outside counsel for routine matters. Industry panels, such as the Association of Corporate Counsel’s recent AI-focused sessions, suggest continued refinement of governance frameworks and board reporting to balance speed with oversight.
