Colorado is taking the rule-amendment route on AI regulation for lawyers. The Colorado Supreme Court proposed amendments to the Rules of Professional Conduct explicitly addressing technology and AI competence, with a public hearing held December 17, 2025. For the 23,249 attorneys in Denver, Colorado Springs, Boulder, and Fort Collins, formal AI-specific rules are close to becoming reality.
AI Regulation in Colorado: The Current Landscape
Colorado's approach to AI regulation for attorneys is centered on the Colorado Supreme Court rather than the state bar. The court proposed amendments to the Colorado Rules of Professional Conduct that directly address AI and technology competence. Specifically, the proposed revisions to Comment [8] and the addition of new Comment [9] to Colo. RPC 1.1 establish the obligation to maintain competence in light of technological developments, including AI.
A public hearing on the proposed amendments was scheduled for December 17, 2025. The Colorado Bar Association has contributed to the conversation through published articles on 'Artificial Intelligence and Professional Conduct' and 'Generative AI and the Law' in the Colorado Lawyer magazine, but the real regulatory momentum is coming from the Supreme Court.
Colorado courts have already dealt with the consequences of unregulated AI use. Documented cases exist where attorneys submitted AI-generated filings containing fictitious cases, violating the duty not to make false statements to tribunals. These incidents are part of what's driving the push for explicit rules rather than relying on existing professional conduct rules to cover AI situations implicitly.
What the Colorado Bar Says About AI
The Colorado Bar Association hasn't issued a standalone formal ethics opinion on AI, but it has addressed the topic through substantive publications. The Colorado Lawyer magazine published articles on 'Artificial Intelligence and Professional Conduct' and 'Generative AI and the Law' that analyze how existing ethical obligations apply to AI tools.
These publications aren't binding guidance in the way a formal ethics opinion would be, but they signal the bar's thinking. The articles emphasize that AI use doesn't create new ethical obligations so much as it creates new ways to violate existing ones. Competence, candor, confidentiality, and supervision all apply, and AI makes each of them more complex.
The primary guidance will come from the Supreme Court's rule amendments once finalized. The proposed amendments to RPC 1.1 Comments [8] and [9] specifically reference technology competence, making it clear that understanding AI tools is part of a Colorado attorney's duty of competence. This is more authoritative than bar articles and will be binding once adopted.
Court Rules and Judicial Guidance
The Colorado Supreme Court's proposed amendments to the Rules of Professional Conduct are the most significant development. The revisions to Comment [8] and new Comment [9] to Colo. RPC 1.1 address technology competence directly. The public hearing held December 17, 2025, was the formal step in the adoption process.
Colorado courts have also dealt with AI issues in practice. Cases involving attorneys submitting AI-generated filings with fictitious citations have been documented, with courts finding violations of the duty not to make false statements to tribunals. These cases demonstrate that Colorado courts are already enforcing AI-related accountability under existing rules, even before the proposed amendments take effect.
Practical Implications for Colorado Attorneys
Colorado attorneys should treat the proposed RPC amendments as already applicable in spirit. The Supreme Court has signaled its position clearly: technology competence, including AI competence, is part of a lawyer's duty under Rule 1.1. Waiting for the formal adoption date to start complying is a mistake.
For Denver's large legal market (home to the majority of Colorado's 23,249 attorneys), the practical impact is significant. Firms need AI policies that address competence requirements, supervision structures, and verification protocols. The documented cases of AI-generated fictitious citations in Colorado courts mean that judges here are already sensitized to the issue.
The fact that Colorado is embedding AI competence in the Rules of Professional Conduct rather than issuing a standalone ethics opinion is significant. Ethics opinions are advisory. Rule amendments are binding and enforceable through the disciplinary process. Colorado attorneys who fail to develop AI competence won't be violating a suggestion; they'll be violating a rule.
What Attorneys in Colorado Should Do
First, review the proposed amendments to Colo. RPC 1.1 Comments [8] and [9]. Understand what technology competence means in the context of AI tools. This isn't about becoming a technologist. It's about understanding what AI can and can't do, how it fails, and what verification is required before relying on its output.
Second, build your firm's AI policy before the amendments are formally adopted. Cover approved tools, prohibited uses (client data in consumer AI), mandatory verification of AI-generated content, and supervisory responsibilities. The firms that build policies now will be in compliance on day one; the firms that wait will be scrambling.
Third, train your attorneys and staff. The proposed amendments make technology competence an explicit obligation, which means CLE on AI isn't optional anymore. Ensure everyone in the firm who uses AI tools understands the capabilities, limitations, and ethical boundaries. Document this training as evidence of compliance.
The Bottom Line
Colorado is embedding AI competence directly into the Rules of Professional Conduct through Supreme Court amendments. The public hearing was December 17, 2025, and formal adoption is expected. This is binding, enforceable regulation, not advisory guidance. Colorado attorneys need to treat AI competence as a mandatory professional obligation starting now.
