Mississippi AI Ethics Rules for Lawyers

The official instruments

Two instruments, one of them the opinion

Mississippi is a two-document jurisdiction, and the cleanest way to use it is to keep the two documents in their lanes. The first is Ethics Opinion No. 267, a formal opinion of The Mississippi Bar issued November 14, 2024. The second is “AI Tools for Lawyers: A Practical Guide,” published roughly eight months later, on July 1, 2025, by the Bar’s Law Practice Management and Technology Committee. They are easy to blur, because both carry the Bar’s name and both address AI, but they do different jobs and carry different weight. Opinion 267 is where the ethics duties live. The Practical Guide is guidance: a practitioner-oriented survey that defers to the opinion on the questions that actually bind. Cite 267 for what lawyers must do, and cite the Guide for what it is, a tool survey, not a second opinion.

That separation is worth stating plainly because it is the kind of distinction trackers routinely get wrong. A jurisdiction with both a formal opinion and a later committee guide can look like it has “two AI opinions,” which overstates the authority of the guide and understates the primacy of the opinion. Mississippi has exactly one formal AI ethics opinion, Opinion 267, plus a separate guidance document that points back to it.

What Ethics Opinion No. 267 actually requires

Opinion 267 builds on existing duties rather than inventing a new regime, and four threads carry the analysis. Confidentiality first: the opinion recognizes an affirmative duty to protect client confidentiality under Rule 1.6, which means a lawyer must account for how a tool handles inputs before client information goes anywhere near it. Verification second, and this is the opinion’s most citable feature: it imposes a duty to verify the accuracy of AI work by expressly adopting ABA Formal Opinion 512’s trust-but-verify analysis. Mississippi did not write its own verification standard from scratch; it took the ABA’s and made it the state’s, which means an AI output is a draft to be confirmed, never a result to be trusted. Billing third: the opinion treats reasonable billing as efficiency gains belonging to the client, with time spent learning the tool falling on the firm as overhead. And consent fourth: informed client consent is required in certain situations under Rule 1.4, a fact-driven trigger rather than a blanket rule.

For implementation, those four threads map onto a familiar artifact set. An approved-tools register that documents each tool’s confidentiality behavior satisfies the Rule 1.6 inquiry. A verification workflow that gates every filing and client deliverable operationalizes the adopted ABA 512 standard. Billing discipline that excludes learning time and passes efficiency to the client satisfies the fee analysis. And an engagement-letter approach to AI disclosure handles the Rule 1.4 consent situations at intake. The policy template assembles those pieces, and the state comparison table places Mississippi’s consent posture among the states.

How to use the Practical Guide, and what to do now

The Practical Guide earns its place on the shelf, as long as you use it for what it is. It surveys AI tools by category, covering case management, e-discovery, research, contract analysis, and more, which makes it a useful orientation to the market. Its ethics section is short by design and defers to Opinion 267, and the Guide is explicit that it is not an endorsement of any tool. So treat it as a map of the landscape, not as a compliance authority: when the Guide and the opinion both touch a question, the opinion governs. That is the honest reading, and it keeps the Guide from being over-cited.

For a Mississippi practice, the to-do list comes from Opinion 267. Protect confidences under Rule 1.6 with a register that documents tool behavior; verify every AI output to the ABA 512 standard the opinion adopted; bill only actual time and keep learning time as overhead; and capture informed consent in the Rule 1.4 situations that call for it. Use the Practical Guide to shortlist tools, then run each candidate through the opinion’s duties before you adopt it. The home page tracks both Mississippi instruments with honest labels, formal opinion and guidance, and the changelog records any update to either.

One layer neither instrument resolves is the courtroom. Mississippi has no single statewide court rule dictating AI disclosure in every filing, so the obligations that bite on a given matter are driven case by case, including judge-by-judge standing orders, particularly in the federal districts. The court orders guide covers the per-filing check Mississippi practice still requires, and the Ropes & Gray tracker is the place to confirm a specific judge’s order before you file.
