AI Is Starting to Change the Economics of Legal Work.

As AI reduces the effort required for parts of research, review and drafting, legal organisations may need to reconsider productivity, pricing, quality and the structure of professional work.

Adoption Is No Longer the Interesting Question

Legal AI adoption is now broad enough that adoption itself is not the most interesting question left to ask. 92% of legal professionals surveyed now use at least one AI tool in their daily work. Adoption skews meaningfully by firm size, firms with 51 or more lawyers report 39% generative AI adoption, against roughly 20% for firms with 50 or fewer, but solo practitioners and small firms are, counterintuitively, moving fastest of all, with 71% of solo practitioners and 75% of small firms reporting adoption in Clio’s 2026 survey.

The more consequential question is what that adoption is doing to how legal work is measured, priced and structured, because the productivity effect is now large enough to show up in firm-level financial outcomes, not just individual time savings.

The Productivity Numbers Are Starting to Show Up in Revenue

62% of legal professionals report time savings of 6–20% per week from AI use, and 52% report revenue increasing at a roughly proportional rate, a meaningful signal that these efficiency gains are translating into commercial outcomes rather than simply freeing up unbilled time. Broken down further, 38% save one to five hours a week, 14% save six to ten hours, and 5% save eleven to fifteen hours; only 6% report no productivity gain at all.

Firms deploying AI broadly are roughly three times more likely to report revenue growth than non-adopters, a gap wide enough that it is becoming a competitive rather than merely operational consideration. Unsurprisingly, law firm technology budgets had grown almost 40% by the end of 2025 compared with pre-GenAI levels, reflecting a shift from treating AI tooling as discretionary spend to treating it as a core input to firm competitiveness.

Central Insight

The billable hour has always priced legal work by the time it took to produce, which worked reasonably well when time and effort were closely correlated with the amount of value delivered. AI breaks that correlation in specific places, a research task that took four hours now taking forty minutes does not mean the resulting advice is worth a tenth as much to the client, which is precisely the tension now surfacing in how legal work gets priced.

Why Pricing and Role Structure Are the Next Pressure Point

80% of law firm respondents to Thomson Reuters’ 2025 Future of Professionals report expect AI to fundamentally alter how they conduct business, specifically around how firms price, staff and deliver legal work to clients. The direction of travel is toward greater pressure on lawyers to justify fees based on value delivered rather than hours logged, since clients are increasingly aware of how much faster certain tasks have become.

That has direct implications for how legal organisations structure junior roles traditionally built around research and first-draft review, the tasks AI now performs a meaningful share of, and for how firms measure and reward productivity once time spent stops being a reliable proxy for value created. Neither question has a settled answer yet. Both are now unavoidable for any legal organisation with a genuinely embedded AI tool, rather than a tool used occasionally by a handful of enthusiastic associates.
