Ohio does not require lawyers to disclose AI use as a general rule. The Ohio Board of Professional Conduct's AI ethics guide applies the existing duties to AI, and routine AI-assisted research generally needs no disclosure. The lawyer must verify every AI-generated citation before filing.
Ethics guidance
Ohio Board of Professional Conduct, AI Ethics Guide for Lawyers and Judicial Officers
2026
Ohio's reference point is the Ohio Board of Professional Conduct's ethics guide on artificial intelligence for lawyers and judicial officers, released in 2026.
The guide treats AI as a relevant technology under the competence rule. It directs lawyers to understand the tools, verify output, protect confidentiality, and bill fairly. Routine AI-assisted research generally needs no disclosure; disclosure matters more where AI shapes the work product or involves client data.

Disclosure rules
Are Ohio lawyers required to disclose AI use?
Ohio has no statewide rule requiring disclosure of AI use. The Board's guide frames disclosure as situation-dependent and points lawyers to each court's own rules.
Counsel should review the assigned judge's standing order in each matter.

Sanctions on record
AI hallucination sanctions in Ohio
No Ohio state-court AI-hallucination sanction is on record as of June 2026. A federal court in the Southern District of Ohio sanctioned two attorneys, held them in contempt, and referred them to the Ohio disciplinary authorities for filing fabricated AI citations, but that matter arose in federal court rather than an Ohio state court.
Competence duty
The competence rule and AI (Rule 1.1)
The competence duty in Ohio is Ohio Rule of Professional Conduct 1.1. The Board's guide treats AI as a relevant technology, so competence includes understanding a tool's risks and verifying its output.

How to stay compliant
A practical checklist for Ohio lawyers
Ohio's Board of Professional Conduct has issued a formal AI guide, and its throughline is verifying AI output.
Review the assigned judge's standing order and the court's local rules at the start of every matter. AI disclosure obligations generally sit at the court and judge level rather than in a single statewide rule.
Verify every citation and quotation before filing, and read the underlying authority. Most AI sanctions have resulted from citations the lawyer never personally verified.
Do not enter confidential client information into public AI tools without confirming how the tool handles data and, where there is material confidentiality risk, obtaining the client's informed consent.
Inform the client when AI use materially affects the matter, and honor any client instruction that limits AI use.
Bill only for time actually spent drafting prompts and reviewing output, not for time the tool saved.
Keep any required technology or AI continuing-education credit current, and treat AI competence as part of your duty under the competence rule.
When evaluating tools, look for citation grounding that ties output to verifiable authority, a vendor commitment not to train on client data, and audit trails. These reduce risk, but they do not replace the lawyer's own review.
