How the Missouri expungement petition actually works.

By Ty McDuffey, J.D. · Back to the hub

A Missouri expungement petition is filed in the circuit court of the county where the case happened, notice goes to the prosecutor and every listed agency, objectors get thirty days, and a judge decides — the statute allows six months, and uncontested cases commonly resolve in ninety to one hundred twenty days.

Where do I file an expungement in Missouri?

In the circuit court of the county where the offense was charged — not the county where you live now. A record with cases in three counties means three petitions in three courthouses, each with its own filing fee. This venue rule is why "statewide" flat-fee expungement services still have to know their way around individual county practices.

The process, step by step

1. Pull your record and verify the details. Case numbers, exact charges, dispositions, and sentence-completion dates — from Case.net and, where needed, a Highway Patrol criminal record check. Petitions fail on wrong details more often than wrong law.
2. Draft the petition. It must name every entity holding the records — court, prosecutor, arresting agency, Highway Patrol repository — and list each offense to be expunged.
3. File and pay. The statutory surcharge is $250 (waivable for indigency), plus the county's civil filing costs. Full cost breakdown here.
4. Notice and the thirty-day window. The prosecutor and named agencies are served; they have thirty days to object. No objection often means no hearing fight — some counties grant clean petitions on the papers.
5. The hearing. If there's an objection or the judge wants one, you appear and the court weighs the statutory criteria — time passed, conduct since, and whether your circumstances warrant relief. For eligible offenses with clean records, the statute leans toward granting.
6. The order and the cleanup. The court must rule within six months of filing. A granted order goes to every named agency, which then seals its copy of the record. Keep a certified copy of the order forever — it's your proof if a stale database resurfaces the entry.

How long does expungement take in Missouri?

The statute gives courts six months to rule. In practice, uncontested petitions commonly resolve in ninety to one hundred twenty days from filing — faster in counties that rule on the papers, slower where a hearing gets set. Multi-county records run on parallel clocks, one per courthouse.

Petition vs. waiting for the automatic system

If your record is inside the Clean Slate law's automatic lane and nothing urgent rides on it, patience may be free. If it isn't — or you can't wait for a state rollout — this process is the road. Here's exactly what the automatic system covers.
