What is a Misdemeanor?
In Missouri, a misdemeanor is a criminal offense that is less severe than a felony but more serious than an infraction. While felonies often result in lengthy prison sentences, misdemeanors generally carry penalties of up to one year in a county jail, along with potential fines, probation, community service, and other consequences.
Common examples of misdemeanors include petty theft, simple assault, possession of small amounts of marijuana, or driving while suspended. While these offenses may seem minor, the impact of a conviction can extend far beyond the courtroom, making it critical to have skilled legal representation.
Common Types of Misdemeanors in Missouri
Missouri law outlines many offenses that can be charged as misdemeanors. Some of the most common include:
- Assault (3rd Degree): Acts involving the attempt or actual infliction of physical injury to another person, without a weapon or serious bodily harm, may be charged as a misdemeanor.
- Theft & Shoplifting: Stealing property or merchandise valued under a certain amount (often $750 or less) can result in misdemeanor charges.
- Possession of Marijuana or Drug Paraphernalia: While Missouri has changed its marijuana laws in recent years, unlawful possession in certain contexts can still be treated as a misdemeanor.
- DWI (First Offense): A first offense for driving while intoxicated is generally a Class B misdemeanor, but penalties can escalate if aggravating factors are present.
- Driving While Suspended or Revoked: Operating a vehicle with a suspended or revoked license can lead to criminal charges.
- Trespassing: Knowingly entering or remaining on another person’s property without permission is often charged as a misdemeanor.
- Vandalism / Property Damage: Causing damage to another person’s property can lead to misdemeanor penalties if the damage falls under a certain monetary threshold.
Misdemeanor Classes & Penalties in MO
Missouri divides misdemeanors into four classes: A, B, C, and D, with Class A being the most serious and Class D the least.
Class A Misdemeanor
- Maximum Penalty: Up to 1 year in county jail and/or a fine up to $2,000
- Examples: 3rd degree domestic assault, theft under $750, certain DWI charges
Class B Misdemeanor
- Maximum Penalty: Up to 6 months in county jail and/or a fine up to $1,000
- Examples: First-offense trespassing, first-offense property damage
Class C Misdemeanor
- Maximum Penalty: Up to 15 days in county jail and/or a fine up to $750
- Examples: Some traffic offenses, minor in possession of alcohol
Class D Misdemeanor
- Maximum Penalty: Fine up to $500 (no jail time)
- Examples: Certain minor traffic violations, littering
It’s important to remember that misdemeanor charges can sometimes be enhanced to felonies based on prior convictions or aggravating circumstances. Additionally, even the lowest-level misdemeanor conviction will appear on your criminal record, which can impact employment, housing, and licensing opportunities.
St. Louis Misdemeanor FAQs
Can a misdemeanor be expunged in Missouri?
Yes, many misdemeanor convictions can be expunged after a waiting period (often 1 to 3 years after completion of your sentence), provided you meet certain eligibility requirements.
Will a misdemeanor show up on a background check?
Yes. Employers, landlords, and licensing boards can see misdemeanor convictions on a background check unless the record has been expunged.
Can I go to jail for a misdemeanor in Missouri?
Yes, Class A misdemeanors can carry up to 1 year in jail, and other classes can still involve some jail time. However, with a strong defense, jail may be avoided in many cases.
What if I can’t afford a lawyer?
You have the right to request a public defender if you meet income eligibility guidelines. However, many people choose a private attorney for more personalized and focused representation.
Do misdemeanors ever turn into felonies?
Yes. Repeat offenses or aggravating factors—such as using a weapon, causing serious injury, or prior convictions—can elevate a misdemeanor to a felony.
