Law firm AI adoption statistics 2026: Clio, ABA and others compared

Surveys put lawyer AI use anywhere from about 30 percent to over 80 percent, because they ask different questions of different samples in different years. Clio's reports describe majority use; the ABA's 2024 data, published in 2025, reported about 30 percent. Compare the definition, sample and year before quoting any figure.

How many lawyers use AI?

Last reviewed: 30 October 2026. Figures can change quickly; this page was prepared on 30 October 2026, and the main primary reports could not be opened from our research environment, so every number is attributed to the report or a secondary source and labelled.

The short answer: it depends on the survey. A figure around 30 percent comes from the American Bar Association's technology survey (2024 data, published March 2025). Clio's survey of legal professionals reported adoption of AI to some extent at around 79 percent in an earlier edition, and its 2026 solo and small-firm report is described by Law360 as finding 71 percent of solos and 75 percent of small firms using AI. Those are not contradictory; they measure different things.

The comparison table (source, year, sample, definition)

SourceYear / editionFigure as reportedSample / definitionStatus
ABA Legal Technology Survey2024 data, published March 2025About 30% use AI, up from 11%; about 18% of solos, 30% of firms of 10-49, 46% of 100+Private practice attorneys, reported as 512 respondents; AI use in practiceReported by LawSites and ABA Journal; primary not opened by us

Why do the numbers disagree?

  • Definition: 'adopted some AI' includes a lawyer who tried a chatbot once; 'use in practice' is narrower.
  • Level: personal use differs from firm-level deployment.
  • Sample: Clio's surveys draw on legal professionals including customers, which may skew toward technology adopters. The ABA survey covers private practice attorneys.
  • Year: AI use rose sharply; a 2024 figure published in 2025 is not a 2026 figure.
  • Mislabelling: aggregators repeatedly relabel older surveys as new ones. One of the sources we reviewed noted that blogs describe the ABA data as a '2025 survey' when it is 2024 data.
  • Vendor interest: Clio and Thomson Reuters sell products; their analyses are useful but not neutral.

What do the figures say about policy and results?

Taken as reported, the gap between use and governance is the interesting part. In the data above, usage is a majority or large minority, while reported lack of a formal policy is in the 50s percent for small firms (unverified) and fewer than a third of solo and small firms report growing revenue with AI (Law360 report of Clio data).

If that is also true in your firm, the practical step is not another tool but a one-page policy and a verification routine.

How should you quote these statistics?

  1. Name the survey, publisher and year: 'According to the ABA's 2024 technology survey, published in 2025...'
  2. State the definition: personal use, firm use or any adoption.
  3. Say who was surveyed and how many, if the report says.
  4. Flag vendor-published data.
  5. If you only have a secondary source, say so, and link the primary report if it exists.
  6. Add the date you checked it.

Update log: 30 October 2026, first version. Figures marked unverified should be checked against primary reports before use in client or marketing material.

Frequently asked questions

What percentage of lawyers use AI in 2026?
It depends on the survey. The ABA's 2024 data, published in 2025, reported about 30 percent; Law360's report of Clio's 2026 solo and small-firm survey says 71 percent of solos and 75 percent of small firms use AI. Definitions and samples differ, so quote the survey and year.
Why do AI adoption surveys for law firms disagree?
They measure different things (any adoption, personal use or firm deployment), sample different groups (vendor customers, ABA members), and span different years. Aggregator sites also mislabel older surveys as current, so check the original publisher.
How many solo lawyers use AI?
The ABA's 2024 data reported about 18 percent of solos, while Law360's report of Clio's 2026 survey says 71 percent of solos use AI. Those are different years, definitions and samples, so they are not directly comparable.
How many law firms have an AI policy?
A May 2026 NC Bar article reportedly gave 57 percent of solos and 55 percent of small firms with no AI policy, and Thomson Reuters' 2025 edition was reported at 52 percent with no formal policy. Both are secondary and unverified here.
Are Clio's statistics reliable?
Clio publishes large annual surveys and uses its own customer data, which is valuable but vendor-interested and may skew toward technology adopters. Read the methodology in the primary report and compare with independent surveys such as the ABA's.
