Legal technology used to change slowly enough that firms could wait a year or two before deciding whether a new tool was worth adopting.
That's no longer true.
Legal tech spending just posted its fastest growth in almost two decades, and the trends below explain why: artificial intelligence has moved from a conference talking point to something most attorneys use every week, while investment, cybersecurity, and governance are all shifting to keep up with it.
Law firms have historically moved slower than other industries on new technology, for reasons we've covered in our piece on digital transformation in law firms. That history is part of why the trends below matter: several show the legal industry closing a gap it's had for years, while others show new risks opening just as quickly.
Here are 12 legal technology trends shaping law firms and legal departments in 2026, along with the current data behind each one.
1. Generative AI Adoption Has Gone Mainstream
Generative AI in law firms has gone from pilot project to standard practice. 92% of legal professionals now use at least one AI tool in their daily work, per Wolters Kluwer's 2026 Future Ready Lawyer Survey. Formal, firm-wide adoption is catching up too: the ABA's 2024 survey put it at 30% of law firms, nearly triple the 11% it found a year earlier. Thomson Reuters found a similar jump among the professionals it surveyed: 26% already using generative AI, up from 14% in 2024.
2. AI Use Is Expanding Beyond Research and Into Document Work
Legal research used to be the obvious AI use case. It still ranks high, but it's no longer the only one. Document review tops the list at 74%, followed by legal research (73%), document summarization (72%), and brief or memo drafting (59%), according to Thomson Reuters' 2025 GenAI report.
3. Legal Tech Investment Is Surging
Money is following adoption. Legal tech funding reached $5.99 billion in 2025, up 22% from 2024, even though nearly 30% fewer companies raised money that year. Investors are consolidating around fewer, larger bets.
The legal AI market alone was valued at $1.4 billion in 2024 and is projected to reach $3.9 billion by 2030. Zoom out further and the entire legal technology market, cloud, AI, cybersecurity, and everything between, is worth $29.81 billion in 2025, on track to more than double to $73.32 billion by 2035.
4. Firms Are Backing That Investment With Real Budget Increases
Law firm technology budgets grew 9.7% in 2025, the fastest real spending growth the legal industry has seen since at least the 2007 financial crisis, per the joint Thomson Reuters and Georgetown Law report on the state of the U.S. legal market.
It's paying off in a measurable way: firms with a documented AI strategy are 3.9 times more likely to report meaningful business benefits than firms without one. Building that kind of strategy is the starting point of digital transformation consulting.
5. AI's Return on Investment Is Becoming Measurable
Adoption is one thing; results are another, and firms are starting to see both. 62% of legal professionals report saving 6% to 20% of their work week using AI, per Wolters Kluwer's 2026 survey. On the revenue side, 52% attribute a 6% to 20% increase directly to AI adoption, and nearly a third put that increase above 10%.
6. Confidence in AI Hasn't Caught Up With Its Use
Expectations for AI keep climbing. 95% of legal professionals expect it to become a central part of their daily workflow within five years. But comfort with it hasn't kept pace: 81% of law firm leaders say they're internally concerned about AI's reliability and risk, even as usage grows.
7. Accuracy and Hallucination Risk Are Under Real Scrutiny
75% of attorneys cite accuracy and reliability as their top concern with AI tools, according to the ABA's 2024 survey, and the concern isn't hypothetical. Tracked court filings containing AI-generated hallucinations (fabricated case citations, quotes, or legal arguments) topped 1,500 cases by mid-2026, up from roughly 200 just a year earlier. Closing that gap between adoption and confidence is where AI consulting support pays off.
8. Governance and Training Are Lagging Behind Adoption
Most firms are using AI faster than they're managing it. 52% of legal organizations still have no policy governing GenAI use, and 64% report giving employees no formal training on it, per Thomson Reuters.
9. Cloud Computing Has Become the Default, Not the Exception
Cloud adoption is close to universal now. 75% of attorneys use cloud computing for work, up from 69% in 2023 and 60% three years before that. Firms making that shift often lean on managed IT services with specialties in the legal industry to handle the migration and keep it running. The holdouts have a consistent reason: 55% cite confidentiality or security concerns as their top objection, and only 12% plan to replace legacy software with cloud-based systems in the next year.
10. Cybersecurity Gaps Persist Even as Threats Grow
Security habits still lag adoption. Only 54% of attorneys report having two-factor authentication available to them at all. 29% of law firms reported a security breach in the ABA's 2023 survey, while the share of firms with a formal incident response plan actually fell that year, to 34% from 42%. Cyber insurance coverage moved the same direction: 40% of firms carried a policy in 2023, down from 46% the year before.
11. Corporate Legal Departments Are Prioritizing Cost Control
The pressure isn't limited to law firms. Cost control is the top strategic priority for general counsel in the U.S., U.K., and Canada this year, and a third expect their technology spending to increase regardless, per Thomson Reuters' 2025 State of Corporate Law Department report.
12. Most Attorneys Still Don't Consider AI "Mainstream" Yet
Despite everything above, perception lags reality. Only 13% of attorneys consider AI mainstream in legal practice today, while 45% expect that to happen within three years, per the ABA. That gap between what's already happening and what attorneys think is happening may be the most telling trend on this list.
Where Legal Tech Goes From Here
These trends point in the same direction: the legal industry has crossed a real threshold on AI adoption, even as reliability, governance, and cybersecurity discipline haven't caught up. That gap is where the risk sits for firms that move fast without a plan, and where the opportunity sits for firms that don't.
The firms pulling ahead are treating legal technology as infrastructure, not an experiment, and closing the second gap alongside the first. That combination, not adoption alone, is what will separate the firms that benefit from these trends from the ones that just read about them.
