Which states require AI disclosure in court filings?

As of 2026, most states have no mandatory AI disclosure rule. New York adopted Part 161 (effective June 2026), Missouri's 20th Circuit requires disclosure, and Wisconsin's Waukesha County has a family court rule. Most states rely on existing ethics rules.

Do state bar associations have AI ethics guidance?

Several do. Oregon issued the first formal bar opinion. California, Florida, Maryland, and others have issued guidance or formed AI task forces. But guidance is not a mandate -- it's advisory.

Are state AI disclosure rules different from federal rules?

Yes. Federal rules come from individual judges or district-wide standing orders. State rules come from supreme courts, legislatures, or bar associations. They often have different scope, different triggers, and different enforcement mechanisms.
