Public Access to Platte County Records
The Missouri Sunshine Law (Chapter 610 RSMo) governs records access in Platte County. All government records are presumed open. A specific statute must exist to close them. This applies to the Circuit Clerk, the Sheriff's Office, and every other county office.
Section 610.023 requires a response within three business days. The office must produce the records, explain the delay, or deny the request in writing. Any denial must cite the exact law that justifies withholding. You do not need to say why you want the record.
Law enforcement records follow Section 610.100. Arrest logs are always public. They include names, charges, and arrest dates. Investigative files may be closed during an active case. Once charges are filed or the case wraps up, more records open to the public. Given that Platte County has multiple police departments and the Sheriff's Office, each agency handles its own requests under this law.
Expungement in Platte County
Section 610.140 RSMo allows certain Platte County criminal records to be expunged. The law excludes Class A felonies, dangerous felonies, and sex offenses. Many misdemeanors and lower-level felonies may qualify.
Misdemeanors require a three-year wait. Felonies need seven years. The time starts after you finish your full sentence. That means jail, probation, parole, fines, and restitution must all be complete. No new criminal charges can occur during the wait.
