AI Rules for Maryland Law Firms
Last verified July 8, 2026
Maryland's AI-relevant rules for lawyers come from three different directions: a decades-old evidence rule now doing new work, fresh bar association guidance on ethical AI use, and a proposed court rule that would make citation-checking a certified obligation on every filing. Here is what applies to your firm today, and what is still moving through the rulemaking process.
Where Maryland Stands
Maryland has no AI-specific ethics rule for lawyers yet, but two existing instruments already shape how your firm should operate. Maryland Rule 2-504.3, adopted in 1998 to govern computer-generated evidence, has become the operative vehicle for AI evidence disputes. And in 2025, the MSBA's AI and Legal Technology Task Force issued ethical guidance for attorney use of generative AI, backed by four customizable policy templates.
What Your Firm Must Do
Under Rule 2-504.3, a firm planning to offer AI-generated or other computer-generated evidence at trial must file a descriptive pretrial notice by the scheduling order deadline, or 90 days before trial if no such deadline exists, or risk exclusion of the evidence. Under the MSBA's 2025 guidance, your firm is expected to fact-check all AI output, protect client confidences, communicate material AI use to clients, and adopt a written AI use policy.
What's Still Pending
A proposed amendment to Maryland Rule 1-311 would require an attorney's signature on any filing to certify that counsel confirmed each cited authority exists and is authentic, with willful violations triggering discipline. It has not yet been adopted by the Supreme Court of Maryland. Firms should build mandatory citation verification into AI-assisted drafting now rather than wait for the rule to take effect.
