Missouri lets you clear a misdemeanor one year after you finish your sentence, and a felony after three. Those waiting periods are far shorter than most people assume, and a great many people walking around with an old record are already eligible and do not know it. But the law is also strict in ways that surprise people: there is a hard lifetime cap, and some offences can never be expunged no matter how long you wait.
The waiting periods
Under Section 610.140 of the Revised Statutes of Missouri, the clock starts when you complete the authorised disposition — meaning the sentence, the probation, the fines, all of it. Not the date of arrest, and not the date of conviction.
- Felony — at least three years after completing the authorised disposition.
- Misdemeanor, municipal violation or infraction — at least one year after completing the authorised disposition.
You also have to have paid what you owe and have no other charges pending. The single most common reason an otherwise eligible petition fails is unpaid court costs from years ago that the person had forgotten about.
The lifetime cap almost nobody knows about
Expungement in Missouri is not an unlimited resource. The statute caps how much you can clear across your entire life:
Reading that correctly matters. The three-misdemeanor allowance applies to misdemeanors and ordinance violations that carry a possible term of imprisonment. Infractions are not capped. And because the cap is for life, the decision of which two felonies to clear is a real strategic choice if you have more than two — you generally want to spend the allowance on whichever conviction is actually costing you work or housing.
What can never be expunged
This is where hope usually meets the statute. Section 610.140 excludes, among others:
- Class A felonies and dangerous felonies as defined in Section 556.061
- Offences requiring sex offender registration
- Felonies where death is an element of the offence
- Felony assault, domestic assault (misdemeanor or felony), and felony kidnapping
- Intoxication-related traffic or boating offences
- Motor vehicle violations by holders of a commercial driver licence
- Most firearm offences under Section 571.030
- Ordinance violations substantially equivalent to any of the above
Two exclusions that catch people out. A DWI is an intoxication-related traffic offence and is not expungeable under this section — Missouri handles those separately, under narrower rules, and most people asking about it do not qualify. And if you hold a CDL, motor vehicle violations are off the table regardless of how minor they were. If you drive for a living, that is worth knowing before you spend money on a petition.
What expungement actually does
An expungement in Missouri does not delete history. It closes the records and, for most purposes, restores you to the position you were in before the arrest — meaning you can generally answer that you have not been convicted, with certain exceptions written into the statute for particular licensing and employment situations.
What it changes in practice is the background check. The conviction stops appearing on the ordinary commercial screens that employers and landlords run, which is the reason most people file in the first place.
The practical process
- Pull your record first. Not your memory of it — the actual record. Cases get disposed of in ways people do not remember accurately, and old costs go unpaid without anyone realising.
- Check eligibility against each conviction separately. The waiting period, the exclusions and the lifetime cap all apply per offence.
- File in the court where the case was heard. If your convictions are in several counties, that is several petitions, not one.
- Expect the prosecutor to be served and to have the chance to object. A hearing gets set.
- Follow through on the order. The order has to reach the agencies holding the records for the practical benefit to arrive.
Common questions
Does the waiting period start at conviction or at the end of probation?
At completion of the authorised disposition. If you were sentenced to two years of probation, the clock starts when probation ends, not when you were sentenced. This is the single most common misunderstanding.
I have unpaid fines from years ago. Does that stop me?
Generally yes. Outstanding financial obligations from the case are a standard reason a petition is denied. The good news is it is usually a fixable problem rather than a permanent bar.
Can I expunge an arrest that never led to a conviction?
Missouri has a separate provision for certain arrest records where no charges followed or charges were dismissed. That is a different route with different requirements — worth asking about specifically, because people often assume the three-year felony wait applies when it does not.
Will it come off a federal background check?
A Missouri expungement operates on Missouri records. It does not control federal databases or records held in other states. If you have out-of-state convictions, those need to be handled under that state’s law.
Do I need a lawyer for this?
It is a civil filing and people do file on their own. Where it goes wrong is eligibility: filing on an excluded offence, filing before the waiting period has run, or spending one of only two felony slots on the wrong conviction. Those mistakes cost you the filing fee and, in the case of the cap, something you cannot get back.
Find out whether you already qualify
A lot of people are eligible and assume they are not, because they remember a seven-year rule that no longer reflects the statute. If you have an old conviction in Jackson, Clay or Lafayette County that is still showing up on background checks, it is worth ten minutes to find out where you stand.
