AI adoption in legal moves beyond licenses to real business model change
Law firms and legal departments across Europe have moved past the early stages of AI experimentation and are now focused on implementing the technology to fundamentally reshape how they work and charge for services, according to Olivier Chaduteau, founder of Day Two, an AI consulting firm for the legal sector.
Chaduteau identified three phases of AI adoption in legal. The first dismissed AI as irrelevant. The second saw organizations buy licenses to signal market readiness without meaningful implementation. The third phase, where the market now sits, treats AI adoption as non-negotiable and focuses on genuine integration.
The shift matters because it changes the economics. Chaduteau's advisory business, built on AI from the ground up, generates significantly higher revenue than his previous non-AI consulting practice. This directly contradicts a common concern among lawyers: that AI will reduce their earnings.
"AI expands what you can do," Chaduteau said. "It allows a business to take on more matters and do more, resulting in higher revenues."
French law firms and legal departments are now asking consultants how to manage the transformation, he added. The pressure comes from clients-particularly in-house legal teams and general counsel-who expect their external counsel to demonstrate AI capabilities around quality, innovation, and efficiency.
The business model shift
The most significant change involves moving away from hourly billing and cost-plus pricing models that have defined legal services for over a century. Law firms are exploring value-based pricing structures that align with AI-driven productivity gains.
This requires more than software implementation. It demands changes to target operating models, staffing structures, and how lawyers approach their work.
New AI-native law firms entering European markets are forcing incumbents to accelerate. Traditional firms face pressure from both new competitors and their own clients to adopt AI or lose business.
What lawyers should focus on
The opportunity for legal professionals lies in using AI to offload routine work so they can focus on higher-value tasks: strategy, innovation, critical thinking, and client advice.
"AI can help me manage things I don't want to manage anymore because AI is better than me," Chaduteau said. "But also AI can help me innovate and do more interesting work."
Data privacy, confidentiality, and data sovereignty remain essential considerations, particularly in Europe. These are implementation details, not blockers.
Chaduteau will speak at the Legal Innovators Europe conference on June 24-25 in Paris. The event brings together law firm leaders and in-house legal teams to discuss AI adoption strategies and best practices.
