Missouri attorney advertising rules for law firms
Missouri is one of 51 US jurisdictions whose bar regulates lawyer advertising, mostly within the ABA Model Rules 7.1-7.5 framework. This page summarizes what Missouri's rule requires and prohibits, and what it means for your firm's marketing. Always confirm the current text with the regulator before you publish.
What the Missouri rule requires
Like most US jurisdictions, Missouri follows the American Bar Association's Model Rules 7.1-7.5 framework for lawyer advertising, adapted in its own rules of professional conduct. In summary, an advertisement must be truthful and not misleading, must not create unjustified expectations, and must follow the state's specific rules on disclaimers, testimonials, specialization claims and solicitation.
A lawyer's communications about legal services must be truthful and not false or misleading; must not compare services in a way that can't be factually substantiated; must observe the rules on stating or implying a specialization or certification; and must include any disclaimer the jurisdiction requires.

The lines Missouri marketing can't cross
- False or misleading statements of fact
- Claims that create unjustified expectations
- Unsubstantiated comparisons with other lawyers
- Improper "specialist" or certification claims
- Prohibited solicitation of prospective clients
- Testimonials or past results without a required disclaimer
What this means for your Missouri marketing
In practice, a compliant Missouri campaign keeps three habits: every claim is substantiable, every required disclaimer is present, and no ad promises an outcome. That's exactly how we build. A firm marketing in Missouri should be able to point to the rule behind each ad - and 0 of 17 agencies we audited in 2026 cited rule numbers at all.
- Substantiate everything. If you can't prove a claim, it doesn't run.
- Disclaimer discipline. Where Missouri requires a disclaimer, it appears - not in fine print no one reads.
- No outcome promises. We never publish guarantees of results, which every bar prohibits.
