AI Sanctions Tracker

A live record of attorneys sanctioned for AI-hallucinated citations. Curated from public court filings and press coverage. We publish this so the bar can see the trend, the press can cite the count, and Sentinel customers can show their carrier the risk they have eliminated.

Source coverage: federal and state court filings; live counts via researcher Damien Charlotin (HEC Paris) and reporting in NPR, Reuters, Law360. If you spot a missing case, email tracker@aiesquire.io.

Note
Why Sentinel exists

Most of these attorneys did not lie. They trusted their AI tool. Sentinel is the layer between your firm and that trust.

Note
What gets caught

Every cite checked against real case law. Hallucinated cases flagged in red. Misquoted cases in yellow. Bluebook-clean. Certificate ready to file.

Note
What it costs

Solo Sentinel is $147 per month. Your malpractice premium is roughly $4,500 per year. Even a 5% discount pays Sentinel for eighteen months.
