Colorado Rules of Professional Conduct, Rules 7.1–7.3 (as restructured by Rule Change 2020(29)). Colorado adopted the ABA Model Rule framework via Rule Change 2020(29): no filing requirements, no mandatory ad labels, and one distinctive required disclosure tied to specialist claims. Enforcement runs through the general false-or-misleading standard, which Colorado applies to unsubstantiated comparisons and unjustified expectations of results.
Not legal advice. Educational reference only — confirm with the state regulator or your ethics counsel before running any ad.
§ 1
No false or misleading communications
A communication is false or misleading if it contains a material misrepresentation of fact or law or omits a fact necessary to make the statement, considered as a whole, not materially misleading; if it compares the lawyer's services with other lawyers' services in a way that cannot be factually substantiated; or if it is likely to create an unjustified expectation about results.
Colo. RPC 7.1(a)
On Meta: Comparative superlatives (“Colorado's top injury firm”) and results-implying hooks are where Colorado creative fails. Substantiate or cut.
§ 2
Any media allowed; responsible contact information
Lawyers may communicate about their services through any media. Communications must include the name and contact information of at least one lawyer or law firm responsible for their content.
Colo. RPC 7.2(a), (d)
On Meta: Same operational rule as amended New York: firm name plus phone, address, or website in the ad unit itself.
§ 3
Specialist claims require the Colorado disclaimer
“Colorado does not certify lawyers as specialists in any field.”
A lawyer may not state or imply certification as a specialist unless certified by an organization approved by an appropriate state authority or accredited by the ABA, with the certifying organization clearly identified. And any advertisement affirmatively claiming certification as a specialist must carry the disclosure: “Colorado does not certify lawyers as specialists in any field.”
Colo. RPC 7.2(c) and Comment [11A]
On Meta: If the creative says “board-certified,” the Colorado line goes on the creative. If it doesn't claim certification, the disclaimer isn't needed — don't waste the pixels.
§ 4
Solicitation limits
Solicitation means a communication directed to a specific person the lawyer knows or reasonably should know needs legal services in a particular matter. Live person-to-person solicitation for pecuniary gain is prohibited outside the standard exceptions (lawyers; family, close personal, or prior business/professional relationships; routine business users of the service type), and all solicitation stops where the target has declined contact or the approach involves coercion, duress, or harassment.
Colo. RPC 7.3
On Meta: Broad-targeted Meta campaigns are advertising under Rules 7.1–7.2, not solicitation. No filing, no labels, no waiting periods at the rule level — Colorado is one of the lightest-touch states in the country for compliant mass tort creative.
Exhibit — compliant Colorado Meta ad (specialist claim variant)
Colorado imposes no filing, labels, or mandatory generic disclaimers. The one verbatim requirement appears only when the ad affirmatively claims specialist certification — shown here so the required line is visible in context.
Frequently asked
Does Colorado require lawyer ads to be filed or labeled?
No. Colorado follows the ABA Model Rule framework: no pre-filing, no review process, and no mandatory “advertising” label. Compliance turns on the false-or-misleading standard in Rule 7.1 and the content requirements in Rule 7.2.
When is the “Colorado does not certify lawyers as specialists” line required?
Only when an advertisement affirmatively claims the lawyer is certified as a specialist. In that case the disclosure must appear, and the certifying organization must be an approved or ABA-accredited body identified in the ad (Rule 7.2(c), Comment [11A]).
Can Colorado ads mention past results?
Only carefully. Rule 7.1 treats communications likely to create an unjustified expectation about results as misleading, so results references need context and substantiation — and outcome promises are off the table.
