ILTA 2026 Survey: Law Firm AI Usage Soars, Copilot Leads
In 2026, the International Legal Technology Association (ILTA) released its technology survey findings, revealing that Microsoft 365 Copilot is the most popular generative AI tool among law firms globally, with 76% usage or exploration, significantly outperforming dedicated legal AI vendors like CoCounsel and Harvey.
This development is highly significant for legal practitioners as it indicates a strong and growing preference for integrated, general-purpose AI tools over specialized legal AI solutions within the legal industry. The survey, spanning over 500 law firms across a dozen countries, highlights a substantial increase in generative AI adoption, with 94% of firms now using or exploring these tools, up from 80% last year. This trend suggests that law firms are increasingly leveraging existing enterprise technology ecosystems for AI capabilities, potentially influencing future technology procurement strategies, vendor partnerships, and the overall development trajectory of legal tech. The data also reveals interesting variations in AI adoption based on firm size, with larger firms showing a narrower gap between Copilot and other leading legal AI products like Harvey.
While not a legal ruling, this survey reflects the evolving regulatory and ethical landscape surrounding AI in legal practice across various jurisdictions. Law firms operating in different countries, including those represented by ILTA members, must navigate complex ethical guidelines for AI use, data privacy concerns (e.g., GDPR, CCPA, local data protection laws), and professional responsibility rules concerning competence, confidentiality, and the unauthorized practice of law. The preference for Microsoft 365 Copilot suggests firms may be leveraging existing enterprise agreements and security frameworks, which are often subject to stringent compliance requirements, thereby integrating AI within established IT governance structures. This also underscores the competitive market where general tech giants are becoming formidable players in the legal tech space.
The key parties involved in this report are the International Legal Technology Association (ILTA), which conducted the survey, and the over 500 law firms, representing 140,000 lawyers across a dozen countries, who participated. The prominent AI vendors mentioned include Microsoft (365 Copilot), Thomson Reuters (CoCounsel), Harvey, Anthropics (Claude), Legora, Lexis+AI, ChatGPT Enterprise, iManage, and Litera One. The survey's findings provide a snapshot of the current market penetration and perceived value of these various AI solutions within the legal sector.
Attorneys and law firms should closely monitor the continued evolution of AI tools, particularly the integration of general-purpose AI into existing enterprise platforms. Practitioners should critically evaluate their current AI strategies, considering the balance between specialized legal AI solutions and broader, integrated tools like Microsoft 365 Copilot, especially regarding data security, ethical compliance, cost-effectiveness, and interoperability with existing systems. Understanding the market trends revealed by this comprehensive survey can inform strategic technology investments, guide internal training initiatives, and ensure that legal professionals remain competent and competitive in an increasingly AI-driven legal landscape, while also being mindful of the ethical obligations associated with AI deployment.
