AI Rules for Mississippi Law Firms
Last verified July 8, 2026
Mississippi regulates attorney AI use through a single bar ethics opinion, while two 2025 and 2026 statutes lay the groundwork for broader state AI oversight that isn't aimed at law firms yet but is worth tracking if you advise business clients. Ethics Opinion No. 267 is the instrument that actually governs your practice today.
Where Mississippi Stands
Ethics Opinion No. 267 is Mississippi's operative guidance on generative AI in legal practice. Separately, the legislature has been active on AI at the policy level: SB 2426 (2025), Chapter 385, created the Artificial Intelligence Regulation Task Force made up of top state officials to recommend how Mississippi should oversee AI going forward, and HB 1723 (2026), Chapter 311, signed March 9, 2026, wrote a federal-style definition of artificial intelligence into the Mississippi Code. Neither statute imposes compliance duties on your firm yet; HB 1723 is purely definitional and sets up the terms future regulation will use.
What Your Firm Must Do
Under Ethics Opinion No. 267, your firm must verify the accuracy and sufficiency of all generative AI work product before relying on it, take reasonable precautions to protect client confidences in any AI tool you use, and not bill a client for time the AI tool did not actually consume. The opinion also requires disclosure of AI use in three specific situations: when you're charging the client for the AI tool itself, when the AI use puts client confidentiality at risk, or when a court rule requires disclosure. The federal court for the Northern District of Mississippi has shown what skipping that verification costs: in Withers v. City of Aberdeen, No. 1:24-CV-218-SA-RP (N.D. Miss. June 8, 2026), the court sanctioned all four attorneys of record after three memoranda cited AI-hallucinated cases, revoking two out-of-state lawyers' pro hac vice admissions and barring them from the district for two years, disqualifying the two local counsel who signed without checking the citations, fining all four a combined $8,000, and directing the order to the Mississippi, Louisiana, and Texas bars.
What's Still Pending
The AI Regulation Task Force created by SB 2426 has not yet issued recommendations captured in this data. Firms advising business or technology clients in Mississippi should monitor the Task Force's output, since it is the likely source of the state's next round of AI obligations.
