Carrier Implications

ALPS is active in New Mexico. Coverage gap risk for AI-generated errors is heightened by Opinion 2024-004's express verification requirement. Carriers are adding AI questions to renewal applications; firms without a written AI policy face uncertain coverage outcomes.

New Mexico moved quickly on AI ethics. Opinion 2024-004 concluded that “the responsible use of Generative AI is consistent with lawyers’ duties” under the New Mexico Rules of Professional Conduct, and attached substantive requirements: lawyers must understand a tool’s training, data access, and limitations (Rule 16-101); independently verify all AI-generated citations and analysis (Rules 16-103, 16-303); refrain from inputting confidential information into tools that share or retain data for training (Rule 16-106); screen AI outputs for conflicts (Rules 16-107, 16-108); develop firm-level AI policies and train staff (Rules 16-501, 16-503); and pass AI efficiency gains to clients rather than billing pre-AI hours (Rule 16-105).

The U.S. District Court for the District of New Mexico has a standing order requiring AI disclosure, identification of the specific tool, and accuracy certification. Magistrate Judge Damian Martinez sanctioned an attorney $1,500 plus mandatory bar reporting and AI ethics training after finding six nonexistent ChatGPT-generated case citations; Senior District Judge Judith Herrera ordered $8,640 in sanctions in a pro se case partly attributable to AI hallucinations. State court Judge John P. Sugg (Carrizozo) has issued an individual order requiring AI disclosure at the top of any AI-assisted filing.

Bottom line for a 5-50 attorney New Mexico firm: The State Bar opinion sets the floor. Before filing in D.N.M. federal court, comply with the standing order. Audit every AI tool for data-sharing and training-data practices. Develop a written AI use policy before your next malpractice renewal.
