AI Disclosure Requirements by Court: A 2026 Guide for Attorneys
Courts across the United States are rapidly adopting rules that require attorneys to disclose when AI tools were used in preparing legal filings. These requirements range from mandatory certification that AI output has been verified to standing orders requiring disclosure of any AI assistance. Failure to comply has resulted in sanctions, fines, and disciplinary proceedings against over 716 attorneys since 2023.
This guide tracks the current state of AI disclosure requirements across federal and state courts, explains what each requires, and shows how to comply using cryptographic attestation to document your review process.
Federal Court AI Disclosure Requirements
Federal courts have been at the forefront of AI disclosure mandates. The following courts have issued standing orders, local rules, or judicial guidance requiring AI disclosure:
| Court | Requirement | Status |
|---|---|---|
| S.D.N.Y. (Southern District of New York) | Attorneys must disclose AI use and certify human review of all AI-assisted filings | Required |
| N.D. Tex. (Northern District of Texas) | Standing order requiring certification that AI-generated content has been verified | Required |
| E.D. Pa. (Eastern District of Pennsylvania) | AI use must be disclosed; attorney must certify accuracy of all citations | Required |
| D. Colo. (District of Colorado) | Attorneys certify no AI-generated content is included without human review | Required |
| Fifth Circuit | Certificate of compliance required for AI-assisted briefing | Required |
| Sixth Circuit | Proposed rule requiring AI disclosure in appellate filings | Recommended |
| All Federal Courts (Rule 11) | Existing Rule 11 obligation of reasonable inquiry applies to AI-generated content | Required |
State Bar AI Guidance
State bar associations have issued ethics opinions and guidelines addressing attorney use of AI. These do not create independent disclosure requirements for court filings but establish the ethical framework for AI use in legal practice:
| Authority | Guidance | Status |
|---|---|---|
| ABA Formal Opinion 512 (2024) | Attorneys must review AI output, maintain competence with AI tools, protect client confidentiality | Binding Ethics Opinion |
| California State Bar | Practical guidance on AI use; emphasis on duty of competence and confidentiality | Advisory |
| New York State Bar | AI use permitted with attorney supervision; must verify all outputs | Advisory |
| Florida Bar | Proposed ethics opinion on AI use; disclosure recommended | Advisory |
| Texas Bar | Multiple judicial standing orders requiring AI disclosure in state courts | Required (varies by court) |
What Courts Actually Require
While the specific language varies, AI disclosure requirements generally fall into three categories:
1. Disclosure of AI Use
The attorney must state whether AI tools were used in preparing the filing. This is the minimum requirement and applies in most courts with AI-specific rules. A simple statement like "AI-assisted research and drafting tools were used in preparing this brief" typically satisfies this requirement.
2. Certification of Human Review
The attorney must certify that a human attorney reviewed and verified all AI-generated content, including case citations, statutory references, and factual claims. This is where LegalSeal becomes critical — it creates cryptographic proof that the certification is backed by a verifiable review process, not just an attorney's signature.
3. Verification of Citations
Some courts specifically require attorneys to confirm that every case citation in an AI-assisted filing has been independently verified as real and accurately quoted. This arose directly from Mata v. Avianca, where six fabricated citations made it into a court filing. Judges in these jurisdictions expect attorneys to demonstrate — not merely claim — that citation verification occurred.
The compliance gap: Most courts require certification, but no court has specified how to prove that review actually happened. LegalSeal fills this gap with cryptographic attestation — a tamper-proof receipt linking the attorney's bar number to the specific document they reviewed, with a timestamp proving when the review occurred.
Notable Sanctions Cases
Courts have not hesitated to sanction attorneys who submit unverified AI output. These cases illustrate the real consequences:
- Mata v. Avianca, No. 22-cv-1461 (S.D.N.Y. 2023) — Attorney Steven Schwartz submitted a ChatGPT-generated brief containing six fabricated case citations. The court imposed sanctions on Schwartz and his colleague Peter LoDuca. This case triggered the wave of AI disclosure requirements across federal courts.
- Park v. Kim (2024) — Attorneys faced $5,000 in sanctions for filing AI-generated documents containing hallucinated legal citations without adequate verification.
- Ex parte Lee (Texas, 2024) — Texas court required attorneys to certify AI non-use or verify all citations, establishing one of the first state-level mandatory disclosure frameworks.
- Kruse v. Karlen (D. Minn. 2024) — Attorney disciplined for AI-generated filing containing non-existent case law, despite claiming to have reviewed the document.
The pattern across these cases is consistent: courts treat unverified AI output as a violation of the attorney's duty of candor to the tribunal and the obligation of reasonable inquiry under Rule 11 (federal) or equivalent state rules. The sanctions are not for using AI — they are for failing to verify AI output before submitting it.
How to Comply: A Practical Framework
Compliance with AI disclosure requirements involves three steps:
- Disclose AI use in your filing pursuant to local court rules or standing orders. Check your specific court's requirements — some require a separate certification page, others accept a footnote or cover page notation.
- Verify all AI-generated content before filing. This means checking every case citation, confirming statutory references, and validating factual claims. This is not optional — it is an ethical obligation under ABA Opinion 512 and Rule 11.
- Document the verification with a LegalSeal attestation. Create a cryptographic verification receipt that proves a licensed attorney reviewed the specific document at a specific time. This receipt can be filed as an exhibit or retained in compliance records.
The third step is what distinguishes a defensible compliance process from a vulnerable one. If your review process is ever questioned — in a sanctions motion, malpractice claim, or bar disciplinary proceeding — the LegalSeal receipt provides objective, timestamped, cryptographically verifiable evidence that human review occurred.
Staying Current with AI Disclosure Rules
AI disclosure requirements are evolving rapidly. New standing orders and local rules are issued regularly as more courts confront the reality of AI-generated legal work. The trend is clearly toward more disclosure, more certification, and more documentation — not less.
Attorneys should monitor their specific court's local rules and standing orders, review state bar ethics opinions as they are published, and establish firm-wide AI compliance procedures now, before a sanctions motion forces the issue.
