Law firms in Kansas City: the Missouri and Kansas sides compared, and how to find and vet a firm

This page is for people looking at Kansas City law firms: residents and companies hiring a lawyer, people looking for legal work, analysts and companies that sell to law firms. It compares the two sides of the state line, shows the size mix, explains how to check a lawyer in each state and sets out a prospecting plan.

Kansas City law offices in Census data

County Business Patterns (CBP) 2023 counts offices of lawyers (NAICS 541110) in the Kansas City, MO-KS Metro Area (CBSA 28140).

Missouri side and Kansas side

Cass County's employee total isn't shown because the Census Bureau flags it as high-noise: the noise it adds for confidentiality moved the figure by 5% or more. The eight counties hold 1,191 of the metro area's offices, and the other 20 are spread across its smaller counties.

Add up the listed counties and the Missouri side has 744 offices, the Kansas side 447. Jackson County, which includes downtown Kansas City, is where the large offices are: it has 46% of the region's law offices and 64% of the jobs. Johnson County is the suburban counterpart, with nearly 400 offices of about five people each, and Clay and Platte counties north of the river are small-practice markets.

Grouped, 1,133 offices have 1 to 19 employees, 68 have 20 to 99 and 10 have 100 or more. The 10 is the total less the smaller classes, so two offices sit in classes of 250 or more that the Census Bureau doesn't publish, to protect confidentiality.

The count's limits: it counts offices with paid employees, so a firm with offices in downtown Kansas City and Overland Park counts twice, and lawyers without staff aren't included. The Census Bureau's Nonemployer Statistics found 1,757 legal services businesses with no paid employees in the metro area in 2024, a broader category that includes solo lawyers. In-house and government lawyers are counted in their employers' industries, and no Kansas City law firm is an SEC-registered public company.

Checking a lawyer in Missouri or Kansas

Lawyers can hold both licenses. Check the state where your case will be filed, and if a firm says it practices on both sides, confirm the specific lawyer who will handle your matter is licensed in that state.

Finding a Kansas City firm

1. Start with the KC Lawyer Finder, the Kansas City Metropolitan Bar Association's public search for attorneys in the greater Kansas City area. KCMBA has more than 5,000 members, and it also runs an ADR Finder for mediators and arbitrators.
2. In Johnson County, the Johnson County Bar Association's online directory covers its members, more than 1,300 attorneys, judges and legal professionals.
3. Confirm the license in the Missouri directory or the Kansas attorney directory.
4. Choose by court and county, then by size. For a matter that needs a large team, the Jackson County offices are where the region's bigger firms are concentrated.

Prospecting Kansas City law firms

Both bar associations sell access to their members. KCMBA offers advertising, event sponsorship and space in its printed bar directory; the Johnson County Bar runs a business partner program and sponsorships. Those are the fastest ways to meet many firms at once. For regional context, the Kansas City Area Development Council covers an 18-county, two-state region and publishes a major employers list, which shows where the firms' corporate clients are.

Illustrative example. The company, prices and results are invented.

Westport Docs (westportdocs.example) sells and sets up document management software. It targets the 143 mid-size offices of 10 to 99 employees, weighted to Jackson and Johnson counties. It sponsors one KCMBA event a quarter, then follows up with the administrators it met and with the rest of the list. Two contacts per firm (the administrator and the IT lead or partner who owns technology) is about 286 people. At a 5% reply rate from cold email, plus event follow-ups replying at perhaps 20%, it expects around 20 conversations a quarter; four demos and two deals of $18,000 a year each would pay for the sponsorship several times over. Researching which firms run old file servers is the slow part, and Bebop does that research for each account.

Subject: Good to meet you at the KCMBA [event]

Hi [first name],

Thanks for the conversation about [topic they raised] at [event]. You mentioned [firm] still keeps client files on a shared drive with folders by attorney. That's the most common setup we replace at firms your size on both sides of State Line.

I've attached a one-page migration plan for a [number]-person firm. Worth 20 minutes next week to see if it fits?

[Your name]
