If a court or opposing counsel has flagged AI-fabricated citations in your filing: stop, preserve everything (the prompts, the outputs, the drafts, the tool), do not quietly refile, read the order to show cause twice, and answer exactly what was asked, completely. The documented pattern is that candor mitigates and cover-ups compound, and the compounding starts in the first 72 hours.

The pattern, in four cases
Ordered by severity. Note what escalated each one, because it was never the AI use alone.
Mata v. Avianca, Inc., 678 F. Supp. 3d 443 (S.D.N.Y. June 22, 2023)
Two lawyers filed six ChatGPT-invented cases. When challenged, they stood by the fake opinions, submitted the chatbot's own false assurance that the cases were real, and, in Judge Castel's words, engaged in acts of conscious avoidance. The $5,000 joint fine was modest; the bad-faith finding and the required letters to the client and to the judges falsely named as authors were not. The sanction rested on the doubling down, not the initial error.
Wadsworth v. Walmart Inc., 348 F.R.D. 489 (D. Wyo. Feb. 24, 2025)
Eight of nine cases in a firm's motions in limine did not exist, produced by the firm's in-house AI tool. The attorneys admitted it promptly, withdrew the papers, apologized, paid the other side's fees, and adopted new policies. The court noted all of it, and still fined the drafting attorney $3,000, revoked his pro hac vice admission, and fined the signing and sponsoring attorneys $1,000 each. The lesson runs both ways: the good response was credited, and it still had a floor.
People v. Crabill, No. 23PDJ067 (Colo. O.P.D.J. Nov. 22, 2023)
The attorney discovered before the hearing that his ChatGPT-sourced cases were fictitious, said nothing, and when the judge asked, blamed a legal intern. Six days later he filed an affidavit admitting all of it. The stipulation records violations of competence, diligence, candor, and honesty rules, and the cover story was the aggravator: a suspension of one year and one day, 90 days actually served, the rest stayed on two years of probation. The AI mistake was survivable. The intern was not.
Couvrette v. Wisnovsky, No. 1:21-cv-00157-CL (D. Or. Dec. 12, 2025, and Mar. 23, 2026)
Fifteen nonexistent cases and eight fabricated quotations across three summary-judgment briefs. After the defendants identified the fabrications, lead counsel refiled by Notice of Errata rather than withdrawing, and the refile still misstated the law. Magistrate Judge Clarke called it an attempted cover-up: the briefs were stricken, the client's claims dismissed with prejudice, a $15,500 sanction ordered to the clerk (calibrated at $500 per fake case and $1,000 per fake quotation), and a $94,704.38 fee award apportioned 85 percent to lead counsel and 15 percent to local counsel, $110,204.38 in total, with the order sent to the Oregon State Bar. The largest AI-citation penalty on record, built almost entirely after the flag.
The first 72 hours, step by step
- Stop. File nothing further in the matter until you understand exactly what is wrong. Every additional filing is a new representation to the court, and in two of the cases above the second filing was worse than the first.
- Preserve everything. The prompts, the outputs, the drafts, which tool and which version produced the text. Do not delete the chat history. Destruction after a flag converts a verification failure into a destruction problem, and the preserved record is also the only way to reconstruct how the error entered the filing, which is the first question you will be asked.
- Do not quietly refile. A silent correction leaves the court and your opponent working from a record you know is false. In Couvrette the corrective filing itself became the aggravation. If you correct, correct completely, verify every remaining citation line by line, and disclose the correction on the record.
- Read the order to show cause twice. Then calendar the deadline. These orders ask specific questions: which passages, which tool, who reviewed, when. Mata's order to show cause listed the exact filings and the exact conduct at issue. Answer the order that was issued, not the one you expected.
- Get ethics counsel if the amount or your license is at stake. The same flag can implicate the court's sanctions power, the bar's discipline process, your malpractice carrier's notice requirements, and your duties to your client. Those run on different clocks. This is the step that is cheapest to take early.
- Answer exactly what was asked, completely. The candor duty (Rule 3.3, and Rule 11's certification by signature) does not pause because the answer is embarrassing. The mitigators the courts actually credit are consistent across the record: prompt admission, withdrawal or complete correction, apology, remedial measures, and, in Wadsworth, paying the other side's fees. Rule 11 also has a withdrawal safe harbor in some postures; whether it applies to yours is a question for your ethics counsel, not for a web page.
- Tell your client. In Mata the court ordered the letters to the client itself. Your duty to keep the client informed does not wait for the court to order it.
What the record looks like going forward
Every case above lacks the same document: a record, made before the question was asked, of what the human actually checked. Reconstructed after a flag, that account is your word against the court's doubt. Made at the time, it is evidence.
So the honest version of the product pitch: a receipt made today cannot evidence yesterday's filing. What it does is make sure there is never a next time. The Regulayer Receipt seals, per filing, which AI tools were used, what you personally verified, and your attestation over all of it, signed on your own machine at the moment of filing, verifiable free by the judge deciding whether to believe you. Prevention, not cure. What it is · What your judge's order requires
Questions people ask in week one
Should I tell the court I used AI, now that a citation is flagged?
The candor duty already answers the direction of the question: in the documented cases the denial or the cover story drove the worst outcomes. The specifics, what to say, in what form, and in what order, belong to ethics counsel in your jurisdiction. This page is information, not legal advice.
Can I just refile a corrected brief and move on?
Quietly refiling is one of the documented failure modes: in Couvrette the corrective filing still misstated the law and was treated as a cover-up, and in Lacey v. State Farm the revised papers contained further bad citations on the way to a $31,100 fee award. A correction should be complete, verified line by line, and disclosed, not silent.
Will I lose my license over this?
Not for the AI use itself, on the current record. License consequences have followed candor failures layered on top: Crabill's suspension followed the intern cover story. Fines, stricken filings, revoked admissions, dismissals, and bar referrals are all documented. The amount and your license are exactly the stakes at which ethics counsel stops being optional.
Does deleting the chat history help?
No. It converts a verification failure into a destruction problem. Preserve the prompts, the outputs, the drafts, and the tool and version. That record is also the only way to show, concretely, how the error entered the filing.
Never a next time.
