AI Legal Malpractice

The Mississippi State Bar adopted formal ethics guidance on generative AI use that permits lawyers to reduce verification requirements when using legal-specific tools, provided they have prior experience with the system. Mississippi Ethics Opinion No. 267, adopted verbatim from ABA Formal Opinion 512 issued in July 2024, establishes baseline principles requiring lawyers to protect client confidentiality, use technology competently, verify outputs, bill reasonably, and obtain informed consent. The opinion's core permission—allowing "less independent verification or review" for familiar tools—has drawn sharp criticism for creating standards that contradict the ABA's own cited research.

Courts nationwide have sanctioned attorneys for submitting briefs containing fabricated case citations generated by artificial intelligence tools. Rather than targeting the technology itself, judges have held lawyers personally accountable for failing to verify AI output before filing. A Massachusetts attorney faced discipline for citing fictitious cases produced by AI systems. In the federal case Flycatcher Corporation v. Affable Avenue, a judge imposed severe sanctions including a default judgment after the defendant's attorney repeatedly cited fabricated cases despite warnings. These decisions reflect a judicial consensus that reliance on unverified AI constitutes a breach of professional responsibility, regardless of whether the attorney or the system originated the error.
