Missouri Bar Rule 4-7.3 Explained: Attorney Solicitation Rules

If you're a Missouri attorney considering direct mail to court filing defendants, the first question is always the same: "Is this even legal?" The short answer is yes — and it's not a gray area. Written solicitation is explicitly permitted under Missouri Supreme Court Rule 4-7.3, protected by the First Amendment, and used by hundreds of attorneys across the state every day.

But there are rules. This guide breaks down Rule 4-7.3 in plain English so you know exactly what's allowed, what's required, and what to avoid.

What Rule 4-7.3 Actually Says

Missouri Supreme Court Rule 4-7.3 governs "Solicitation of Clients" — meaning direct, targeted outreach to people you know or believe need legal services. The key distinction is between written solicitation (letters, emails) and in-person solicitation (showing up at someone's door or approaching them in a courthouse hallway).

• Written solicitation: Permitted. You can send letters to individuals you reasonably believe need legal services, as long as you follow specific requirements.
• In-person solicitation: Generally prohibited. You cannot approach potential clients in person for the purpose of obtaining employment, except in limited circumstances (like pro bono work).

This distinction is crucial. Sending a letter to someone who was just charged with a DUI? Perfectly fine. Walking up to them in the courthouse lobby? Not fine.

Requirements for Solicitation Letters

When you send a written solicitation under Rule 4-7.3, your letter must comply with several requirements:

1. "ADVERTISING MATERIAL" Label

Every solicitation letter must include the words "ADVERTISING MATERIAL" on the outside of the envelope. This is non-negotiable. The purpose is to let the recipient know immediately that this is a marketing communication, not official court correspondence or a personal letter from someone they know.

Place it clearly on the envelope — typically on the front, below the return address, or on the back flap. Don't try to hide it or make it illegible.

2. Truthful and Not Misleading

Your letter cannot contain false or misleading statements. This applies to:

• Your qualifications and experience
• The nature of the charges or legal matter
• Promises about outcomes ("I'll get your charges dropped" is a no-go)
• Comparisons with other lawyers (unless factually verifiable)
• Fee arrangements — be clear about what you charge and how

3. Not Coercive or Harassing

Your letter cannot use coercion, duress, or harassment. Don't use fear-mongering language like "You WILL go to jail unless you call me immediately." Present the situation factually and offer your services professionally.

4. Respect "Do Not Contact" Requests

If a person has made known to you that they do not want to receive solicitations, you must honor that request. This is where conflict filtering becomes essential — maintaining a list of people who should never receive your mailings.

5. Identify the Source

If your letter references public record information (like the fact that the recipient was recently charged), you should identify the source of that information. A simple line like "This information was obtained from public court records" satisfies this requirement and builds trust with the recipient.

The Constitutional Foundation

Attorney advertising and solicitation rights are rooted in the First Amendment. The U.S. Supreme Court established in Bates v. State Bar of Arizona (1977) that attorney advertising is commercial speech protected by the First Amendment. Later decisions, including Shapero v. Kentucky Bar Association (1988), specifically held that targeted direct mail solicitation by attorneys is constitutionally protected.

Missouri's rules reflect this constitutional framework. The state cannot ban written solicitation — it can only regulate it to prevent fraud, deception, and overreaching. As long as your letters are truthful, properly labeled, and not coercive, you're exercising a protected right.

Common Misconceptions

Best Practices Beyond the Rules

Compliance with Rule 4-7.3 is the floor, not the ceiling. Here are practices that protect your reputation and improve results:

• Use quality paper and professional printing. A cheap-looking letter undermines your credibility before the recipient reads a word.
• Be empathetic in tone. The recipient just got charged with a crime. Acknowledge the stress of the situation without being patronizing.
• Include your credentials briefly. Years of experience, number of cases handled in their court, relevant specializations — but keep it factual.
• Make it easy to respond. Phone number, email, website, office address. Multiple contact methods increase response rates.
• Keep records. Maintain copies of every letter template and a log of who received mailings. If a bar complaint is ever filed, documentation is your best defense.
• Use conflict filtering. Automatically exclude current clients, opposing parties, and anyone who shouldn't receive your letters.
