A new survey conducted by Everlaw and the Association of Corporate Counsel (ACC) found that GenAI usage in corporate law more than doubled in a single year – jumping to 52% this year compared to 23% reported in 2024. The GenAI Strategic Value for Corporate Law Departments Survey is conducted annually by the ACC in partnership with Everlaw. The 2025 report, based on a survey of 657 in-house legal professionals across 30 countries, provides a comprehensive look at the current state of GenAI adoption within corporate legal departments.

This year’s findings mark a clear turning point.

• Optimism is rising as adoption grows: Half (50%) say AI’s impact will be significant, and one in five (20%) now call it transformative, nearly double last year’s 11% figure. Those expecting only a “moderate” impact fell from 37% to 25%. Only 2% have no plans to use GenAI.
• Benefits are broadening: 91% of legal professionals cite efficiency gains, up slightly from 86% last year. Far more now see better client service (49%, up from 38%) and stronger decision-making (34%, up from 16%).
• Reliance on outside counsel is shrinking: As in-house legal teams are using GenAI for efficiency and to increase self-sufficiency, nearly two-thirds (64%) expect to rely less on outside counsel, an increase from 58% in 2024, and 50% expect reduced outside counsel costs, up from 46%. Backed by current and anticipated efficiency gains, most respondents see an opportunity to reshape their operations by insourcing drafting (78%), contract management (71%), and research (62%), along with elements of higher-level work such as M&A (29%) and litigation (29%).
• Barriers are falling fast: Only 9% now say company policy prohibits GenAI use, down sharply from 29% last year.
• Clients will challenge the billable hour: While 59% report no GenAI savings from their law firms yet, only about a quarter (24%) are satisfied with how outside counsel are adopting GenAI tools for cost effectiveness. A majority (61%) plan to push for change in how legal services are delivered and priced, and half (49%) predict client demand will be the primary driver of billing changes.
• Europe pulls ahead: With 61% of respondents already using GenAI in legal practice and 29% expecting its impact to be transformative for legal teams, Europe shows the highest rates of adoption and optimism globally. European respondents are also more likely to see cost savings from outside counsel.

“One thing every general counsel says about their outside counsel is they want greater value,” Everlaw Chief Legal Officer Gloria Lee said. “Generative AI — used responsibly and always with a human in the loop — will allow law firms to deliver services faster, smarter, and within clients’ ever-tighter budgets.”

“The speed of adoption of artificial intelligence within the workplace speaks volumes,” said Veta T. Richardson, ACC president and CEO. “In-house counsel are not only using AI to make their departments more efficient — they are reimagining how legal work is delivered, how costs are being managed, and how value is defined. This is a pivotal moment for our profession, and ACC is committed to ensuring our members have the insights, tools, and community to navigate this transformation with confidence.”
