Judges Are Checking AI Citations. Are You?
If one citation in your filing is wrong, it is your responsibility — not the AI's.
NeXa checks every citation against primary US legal databases before it reaches a court. Every claim is source-linked. Every output is defensible. No invented cases.
Upload a brief. Get every citation verified with source links in under 10 minutes.
Lawyers who file unverified AI citations are getting sanctioned. Lawyers who use NeXa aren't.
Verified vs. Unverified
This Is What Verified Research Looks Like
The same query. One output is defensible in court. One is a sanctions risk. You can't tell the difference until a judge does.

The Problem
AI Citation Errors Are Reaching the Courts
documented AI citation error cases — and analysts are logging four to five new cases every day. This started with Mata v. Avianca in 2023. It hasn't slowed down.
Lacey v. State Farm — C.D. Cal. 2025
Attorneys at K&L Gates and Ellis George used three separate AI tools for research. The citations were still hallucinated. The tools were working as advertised — they just didn't verify.
City of Athens — Sixth Circuit, March 2026
An appellate brief filed with more than two dozen citations that were incorrect, misrepresented, or entirely nonexistent. The court sanctioned the firm and flagged the brief for AI-generated content.
Courts are not waiting for AI to mature. They are already enforcing standards.

The Standard
Courts Expect Verification
Wadsworth v. Walmart — D. Wyo. February 2025
Morgan & Morgan attorneys were sanctioned $5,000 for filing motions containing AI-hallucinated citations. The ruling was direct.
“As attorneys transition to the world of AI, the duty to check their sources and make a reasonable inquiry into existing law remains unchanged”
— Judge, D. Wyo. · Wadsworth v. Walmart (Feb. 2025)
- • Bar associations are issuing guidance on AI use in legal filings
- • Courts are holding attorneys personally accountable for unverified citations
- • ABA Opinion 512 (July 2024) makes competence obligations explicit
- • Under ABA Rules 5.1 and 5.3, supervising attorneys are responsible for AI-assisted work produced by associates and paralegals they oversee — even if they did not generate it themselves
If you use AI, you verify it. NeXa makes that verification instant.

Common Objections
“ But I Already Verify Citations Myself ”
Most lawyers already verify AI outputs. The challenge isn't whether verification happens.
It's how long it takes, how consistent it is, and whether you have a documented record when a judge asks how you verified.
