The AI mistake getting lawyers sanctioned, and how firms avoid it

The mistake getting lawyers sanctioned is filing documents that cite cases the AI invented, fabricated decisions that look real and do not exist. It is avoidable with one habit: never file anything an AI produced without verifying every citation against the actual source.

This is not hypothetical. It started with a widely reported 2023 federal case in New York, where two attorneys were fined 5,000 dollars after submitting a brief full of ChatGPT-generated cases that turned out to be fictitious. In the roughly two and a half years since, dozens more documented incidents have followed.

Why AI invents cases in the first place

General-purpose AI tools are built to produce fluent, plausible text, not to be correct. Ask one for supporting case law and it will happily generate citations that match the format and tone of real ones, complete with invented parties, reporters, and quotations. The output looks exactly like competent legal research. That is what makes it dangerous.

The fix is process, not avoidance

The firms using AI safely did not swear it off. They built a rule into the workflow: AI can draft and summarize, but a human verifies every factual claim and every citation against the primary source before anything is filed or sent. The AI never gets the last word.

• Treat AI output as a starting draft, never a finished product.
• Verify every citation in the actual reporter or database, not by asking the AI again.
• Use tools connected to real legal databases for research, not a general chatbot guessing from memory.
• Put the verification step in writing so everyone on the team follows it.

Where this leaves a small firm

The lesson is not that AI is too risky for law. It is that AI without a verification process is too risky, and most firms adopting it on their own never build that process deliberately. The guardrail is the whole point, and it is easy to install once someone sets it up correctly.

JurisLabs builds AI into firms with that verification step wired in from the start. If you want the upside without the headline, the first call is free.
