Colorado

Does Colorado require attorneys to disclose AI use in state court filings? Not through a statewide court rule. Colorado's AI disclosure landscape is driven by two forces: individual judge orders in state courts and the Colorado AI Act (SB 24-205), a broad AI governance law with a June 2026 compliance deadline. The AI Act isn't court-specific — it regulates AI across industries — but its transparency and accountability requirements will touch legal practice. Add individual judge orders on top, and Colorado firms face a layered compliance picture.

For managing partners at Colorado firms, the June 2026 AI Act deadline is the hard date on your calendar. Individual judge orders are the immediate concern. Together, they create obligations that a 'no statewide rule' label dangerously understates.

The Colorado AI Act (SB 24-205): What Firms Need to Know

Colorado's AI Act, signed as SB 24-205, is one of the most comprehensive state AI governance laws in the country. It establishes requirements for AI transparency, algorithmic accountability, and consumer protection. The compliance deadline is June 2026. While the Act targets 'deployers' and 'developers' of AI systems rather than attorneys specifically, law firms using AI tools in client-facing work may qualify as deployers under the statute's broad definitions. Key provisions include impact assessments for high-risk AI systems, transparency requirements for AI-generated outputs, and notice obligations when AI is used in consequential decisions. A law firm using AI to draft legal documents that affect client outcomes could trigger these provisions.

Individual Judge Orders: Colorado's Court-Level Requirements

Without a statewide court rule, individual Colorado judges have stepped in with their own AI requirements. These orders appear in district courts across the state — sometimes as standing orders, sometimes as case management directives. The requirements vary: some judges require disclosure of AI use in any filing, others focus on AI-assisted legal research, and some require certification that AI-generated content was human-verified. There's no central database of these orders. Attorneys practicing in multiple Colorado judicial districts must check with each court. Denver County, Arapahoe County, and El Paso County courts are among those where individual judges have addressed AI.

How the AI Act Differs from Court Disclosure Rules

The Colorado AI Act and court-level AI disclosure orders operate on different tracks. Court disclosure orders are procedural — they require you to tell the judge when AI was used in a filing. The AI Act is statutory — it creates substantive obligations around how AI systems are deployed, assessed, and documented. A firm could fully comply with every judge's disclosure order and still violate the AI Act if it hasn't conducted required impact assessments or provided proper notice. The reverse is also true: AI Act compliance doesn't substitute for court-specific disclosure requirements. Colorado firms need parallel compliance tracks.

Federal Courts in Colorado vs. the State Landscape

The District of Colorado has seen individual judges issue AI-related standing orders, consistent with the national pattern of federal courts moving faster than state courts on AI policy. The Tenth Circuit, which covers Colorado, hasn't issued a circuit-wide AI rule, but individual judges within the circuit have addressed AI in their courtrooms. For Colorado attorneys, the federal-state comparison is less relevant than the AI Act vs. court rules distinction. Other states have either court rules or AI legislation — Colorado has both (at different stages), creating a uniquely complex compliance environment.

Compliance Strategy: Preparing for June 2026 and Beyond

Colorado firms need a two-track approach. For court compliance: build a universal disclosure protocol that satisfies the strictest individual judge order you've encountered, and deploy it for every filing statewide. Check standing orders in every district where you practice. For AI Act compliance: start now. First, audit your firm's AI tool usage to determine whether you qualify as a 'deployer' under SB 24-205. Second, conduct impact assessments for AI systems used in high-risk contexts — client-facing legal work likely qualifies. Third, implement documentation and transparency practices the Act requires. Fourth, establish notice procedures for clients when AI is used in their matters. Fifth, assign someone to own the June 2026 deadline — this isn't something to figure out in May 2026.

The Bottom Line: Colorado has no statewide court AI disclosure rule, but individual judges issue their own orders and the Colorado AI Act (SB 24-205) creates statutory AI obligations with a June 2026 deadline. Firms need parallel compliance tracks — court-level disclosure and AI Act statutory requirements.
