AI in legal work: what is real, what is hype, what will get you sanctioned.
Lawyers have been sanctioned for AI hallucinations in real filings. Here is the honest map of where AI works in legal work and where it does not.

Two facts are simultaneously true. AI is meaningfully changing legal work in 2026. AI has also caused several public sanctions of attorneys for citing fictitious cases. Both facts get worse when conflated.
Where AI is working in legal practice
Document review at scale. Reviewing large volumes of documents for relevance, privilege, or specific concepts. AI tools designed for e-discovery have been doing this for years; the recent LLM advances have made them faster and better.
Contract review and redlining. Comparing a draft contract against a playbook, flagging deviations, suggesting language. Several specialized products (Spellbook, Harvey, Ironclad) integrate this into Microsoft Word.
Drafting routine documents. First drafts of NDAs, engagement letters, basic motions, correspondence. The lawyer revises the draft. The draft saves time. The lawyer is still accountable.
Legal research assistance. Summarizing case law, finding relevant authorities, explaining a doctrine. Useful for getting oriented quickly. Not a substitute for actually reading the cases.
Summarizing transcripts, depositions, and long records. Useful, well-bounded, easy to verify.
Where AI will get you sanctioned
Filing a brief that cites cases the AI made up. This has happened in multiple courts since 2023. Sanctions have included monetary penalties, mandatory legal-ethics training, and referrals to bar associations.
The pattern is always the same: the lawyer asked an AI for cases, the AI produced plausible-looking citations, the lawyer did not check whether the cases existed, the lawyer filed the brief, the court noticed.
Providing legal advice that the AI hallucinated. The bar rules on competence have not been suspended for AI. If you give advice that is wrong because you trusted an AI without checking, that is the same competence failure as if you got it from a bad treatise.
Sharing privileged client data with consumer AI tools. If the tool's terms of service give the vendor rights to use the data, you have arguably waived privilege. Several state bars have published opinions to this effect.
What to do
Use AI for everything that benefits from drafting, summarizing, and analyzing content you provide. Verify every specific factual claim, every citation, every quote. Use enterprise plans with appropriate data-use contracts when client data is involved. Read the responses before you act on them.
This is the same standard of care lawyers have always had. AI does not lower it.
The actual disruption
The disruption is not "AI replaces lawyers." It is that the price of competent legal work falls because routine work becomes faster. Firms that adopt AI well will have higher associate leverage and lower hourly rates on routine work. Firms that do not will lose work to firms that do.
This is the same dynamic that follows every productivity-improving technology in legal practice.
