Lexis+ AI Projected to Deliver 344% ROI: What This Means for Hong Kong Law Firms

The Total Economic Impact of LexisNexis Lexis+ AI for Large Law Firms, a commissioned study conducted by Forrester Consulting on behalf of LexisNexis, May 2025, projects that large law firms could achieve a 344% return on investment (ROI) over three years by adopting Lexis+ AI—a pioneering legal technology solution developed by LexisNexis, designed to redefine how legal professionals conduct research, draft documents, and analyse legal content. The study outlines how AI can drive measurable business value through increased efficiency, improved client delivery, and enhanced profitability.

Key Findings from the Study
The study models a composite global law firm with 950 attorneys and 15 research staff, projecting the following three-year, risk-adjusted benefits:

• 344% projected return on investment (ROI) over three years
• Payback in under six months
• $6.5m in net present value profit for the model large law firm

“The Lexis+ AI products can increase the capacity of the firm, meaning that will either grow the top line or reduce the expense that the law firm requires to maintain the same business.”

Implications for Hong Kong Law Firms
While the study focuses on North American firms, the findings are highly relevant to Hong Kong’s legal sector, where firms face similar pressures to:

• Enhance productivity without increasing headcount.
• Deliver faster, higher-quality client service in a competitive regional market.
• Attract and retain top legal talent, particularly younger lawyers who expect access to cutting-edge tools.

Lexis+ AI’s secure, enterprise-grade infrastructure and integration with trusted legal content make it a strong fit for firms operating in Hong Kong’s bilingual, cross-border legal environment.

A Strategic Investment, Not Just a Tech Upgrade
The study emphasises that Lexis+ AI is not a point solution—it is a platform-wide enhancement that supports attorneys across litigation, transactional, and research functions. Key use cases include:

• Accelerating legal research and reducing write-offs.
• Drafting clauses, memos, and correspondence more efficiently.
• Summarising and analysing large volumes of legal documents.
