Short answer: Missouri’s advertising rules sit under Supreme Court Rule 4 and are cited as Rule 4-7.1 and following, not Rule 7.1. Missouri is also among the states that have required prescribed disclaimer language — specific words, rather than a general obligation not to mislead. That distinction changes how a website has to be built, and it is the subject of this guide. This guide sets out the Missouri attorney advertising rules that apply to a law firm website, and where firms most often fall short.
Most states tell you what your advertising must not do. A handful tell you what it must say, verbatim. Those are different engineering problems.
Prescribed wording is a different kind of requirement
By contrast, a general obligation not to mislead leaves you room. You decide how to qualify a past result, how prominently, in what tone. Reasonable choices are defensible.
However, prescribed wording removes all of that. The words are the requirement. You cannot shorten the sentence because it does not fit the column. Nor can you rewrite it to sound less alarming. Equally, a qualification of your own will not do, however gracefully it conveys the same meaning. The meaning is not what is being regulated; the text is.
In practice, this trips up firms and their designers in a predictable way. Someone shortens the sentence to fit a mobile layout, or splits it in a way that changes it, and the site now fails a mechanical requirement while looking perfectly responsible.
The implementation problem
Moreover, mandated text generally attaches to the advertisement, which for a website means asking which pages carry the obligation rather than treating the domain as one unit. Three practical consequences:
A footer instance may not be enough. For example, firms add the sentence once, globally, and consider it handled. Whether a footer occurrence satisfies a requirement attached to a particular advertisement is a real question, particularly on long pages where the footer is thousands of pixels from the claim.
Campaign landing pages are usually missed. The recurring theme of this entire series. Pages built for paid search sit outside the main template, and global footer text does not reach them.
Design systems fight verbatim text. A component library that truncates, or a designer who tightens copy for rhythm, will quietly break a verbatim requirement. Mandated text needs to be marked as untouchable in whatever system holds it.
Get the current wording from the source
This guide deliberately does not reproduce Missouri’s disclaimer text. That is not caution for its own sake — with prescribed wording, a version that is nearly right is worse than no version, because it looks compliant and is not. Requirements of this kind are also amended, and superseded wording circulates widely in agency templates and older articles.
Therefore, get it from the Missouri Bar or the Office of Chief Disciplinary Counsel, in writing, and store it somewhere your design process treats as authoritative.
Mandated text across the series
| State | Mandated element | Nature |
|---|---|---|
| Missouri | Prescribed disclaimer sentence | Verbatim text |
| New York | “Attorney Advertising” label | Verbatim label, home page |
| New Jersey | Award methodology description | Substance, wording flexible |
| Florida | Past-results qualification | Substance, prescriptive context |
| Virginia | None since 2017 | Judgement only |
The useful distinction is the right-hand column. Verbatim requirements are cheap to satisfy and easy to break. Substance requirements are the reverse: they demand judgement but tolerate rewording. A firm operating in both kinds of jurisdiction needs to know which of its disclaimers can be edited and which cannot — and that information almost never survives a website redesign.
A note on the citation format
Missouri’s “4-” prefix is a milder version of the problem covered in the Maryland guide: a search keyed to the standard numbering may return nothing, and nothing reads as no requirement. Worth knowing if you are auditing a multi-state site.
Missouri attorney advertising rules: frequently asked questions
Does Missouri require specific disclaimer wording on attorney advertising?
Missouri is among the states that have required prescribed disclaimer language rather than leaving the wording to the firm. Requirements of this kind are amended from time to time, so confirm the current text, and whether it still applies, with the Missouri Bar or the Office of Chief Disciplinary Counsel before relying on any wording you find published elsewhere.
Which rules govern attorney advertising in Missouri?
The Missouri Rules of Professional Conduct, which are codified under Supreme Court Rule 4 and cited in the form Rule 4-7.1 rather than Rule 7.1. Searching for Rule 7.1 alone may not surface them.
Can I paraphrase a mandated disclaimer to fit my design?
No. That is the defining characteristic of prescribed wording: the words are the requirement. Shortening it, splitting it across lines for layout reasons, or rewording it for tone all risk failing to satisfy the rule even though the meaning survives.
Where does a mandated disclaimer have to appear?
Generally on the advertisement it qualifies, which for a website means thinking about pages rather than the site as a whole. A single instance in a footer template may or may not be sufficient depending on the requirement. Verify rather than assume.
Do mandated disclaimers hurt conversion?
Less than firms fear. A short standard sentence in a small, legible size below a call to action costs almost nothing. What does cost conversion is a large block of nervous legal text stacked above the form.
Missouri attorney advertising rules: the short version
If you take one thing from this guide, take this: the Missouri attorney advertising rules apply to every page a prospective client can reach, including campaign landing pages built outside your main website. That is usually where the gaps are.
