Deloitte: AI Will Handle 30% of In-House Legal Work by 2031
Deloitte projects AI will manage 30% of corporate in-house legal work within five years.
Why it matters: This signals a major shift for in-house legal operations, impacting workflows, costs, and tech strategies across corporate legal departments.
- Deloitte Legal forecasts AI agents will handle 30% of in-house legal work in 3-5 years.
- 20% of in-house attorneys may become hybrid engineer-lawyers in that timeframe.
- 87% of general counsel used generative AI in 2026, up from 44% in 2025.
- 58% of legal departments expect generative AI to reduce reliance on outside counsel.
Deloitte Legal's report, "The AI Imperative: Reshaping of the Legal Industry," predicts that artificial intelligence agents will automate 30% of work within corporate legal teams within the next three to five years. This milestone underscores the rapid pace of AI integration in legal workflows.
In tandem, Deloitte expects that 20% of in-house legal professionals will evolve into "hybrid engineer-lawyers," combining legal expertise with technical skills to manage and optimize AI tools effectively.
The growing adoption is supported by data from the General Counsel Report by FTI Consulting and Relativity, which shows 87% of general counsel using generative AI in 2026, nearly doubling from 44% in 2025. Additionally, 39% of legal departments now view AI as a strategic priority to boost efficiency and efficacy.
Legal departments are formalizing their investments, with 53% having technology roadmaps—more than double the 25% recorded the previous year—and 70% planning new tech investments in the next 12 months.
The shift extends to outside counsel. A survey by the Association of Corporate Counsel and Everlaw found that 58% of legal teams expect generative AI to reduce their dependence on external lawyers, with 25% already reporting cost savings from AI implementation.
Industry leaders emphasize the need for structured training and innovation strategies. Sophie Ross, FTI Technology's CEO, stresses that upskilling and technology roadmaps are essential for managing AI adoption effectively while balancing risk.
By the numbers:
- 30% — projected share of in-house legal work AI agents will handle in 3-5 years
- 87% — general counsel usage of generative AI in 2026, up from 44% in 2025
- 58% — legal departments expecting generative AI to reduce outside counsel reliance
Yes, but: The Deloitte report does not specify which legal tasks AI will automate or detail challenges related to AI integration, leaving some uncertainty about implementation hurdles.
What's next: Legal departments will focus on formalizing AI strategies, upskilling staff, and expanding generative AI adoption over the next year.
