How Missouri Attorney license verification works

A Attorney in Missouri is licensed by the MO State Bar / Supreme Court attorney roll. PrimaryCheck looks the license up live at the board's public verification system (board lookup) by license number, or by name when no number is supplied. The record the board publishes is captured as evidence, hashed, and rendered into a proof PDF.

Fields returned for this board: bar_number name status date_admitted location name_marker.

Board note: mo_bar live 2026-11-04 (plain httpx, iMIS WebForms query grid). GET form for __VIEWSTATE, POST Sheet0 inputs (Last/First Contains, Bar Number Equals), detail Lawyer_Directory_Detail.aspx?ID=<guid> (Full Name, Bar Number, Date Admitted, Location, Current Standing). Directory lists lawyers in good standing only; discipline is OCDC, not here. No DOB so name-only >1 row = ambiguous_match.

`name`	Last name or declared alias matches; first name exact or nickname
`license_type`	The record is a Attorney license, strictly (no near-miss types)
