Frequently Asked Questions

What is the difference between a misdemeanor and a felony in Missouri?

In Missouri, misdemeanors are less serious offenses divided into Classes A, B, C, and D, with Class A being the most serious and carrying up to one year in jail and a fine of up to $2,000. Felonies are more serious crimes classified from Class A through Class E, with penalties ranging from four years up to life imprisonment or the death penalty depending on the offense. Understanding which classification your charge falls under is critical, as felony convictions carry long-term consequences including loss of voting rights, restrictions on firearm ownership, and difficulties obtaining employment.

Can a criminal charge be expunged from my record in Missouri?

Missouri law does allow for the expungement of certain criminal records under Section 610.140 RSMo, which was significantly expanded in 2018 to include many misdemeanor and felony offenses. Generally, you must wait three years after completing your sentence for a misdemeanor or seven years for a felony before petitioning for expungement, and certain serious offenses such as dangerous felonies and sex crimes are not eligible. Consulting with a criminal law attorney can help you determine whether your specific charges qualify for expungement under Missouri law.

What should I do if I am arrested in Jefferson County, Missouri?

If you are arrested in Jefferson County, you have the constitutional right to remain silent and the right to an attorney, and you should exercise both of these rights immediately. Do not make any statements to law enforcement without legal counsel present, as anything you say can be used against you in court. Contact a criminal defense attorney as soon as possible so they can advise you on your options, potentially attend your arraignment, and begin building your defense strategy from the earliest stage of the process.

How does a DWI charge work in Jefferson County, Missouri?

In Missouri, a first-offense DWI is typically charged as a Class B misdemeanor if your blood alcohol content is 0.08 percent or higher, and it can result in up to six months in jail, fines, and a 90-day license suspension. Repeat offenses or aggravating factors such as a very high BAC or a minor passenger in the vehicle can elevate the charge to a felony with significantly harsher penalties. Jefferson County prosecutors actively pursue DWI cases, so retaining an experienced attorney early can make a meaningful difference in how your case is resolved, including whether you may be eligible for a diversion program or limited driving privilege.

What happens at an arraignment in Jefferson County Circuit Court?

An arraignment in Jefferson County Circuit Court is typically your first formal court appearance after being charged with a crime, during which the judge will read the charges against you and ask you to enter a plea of guilty, not guilty, or no contest. Bail conditions may also be reviewed or set at this hearing, and it is important to have legal representation present so your attorney can argue for reasonable bail and protect your interests from the outset. Entering a not guilty plea at arraignment preserves your options and gives your attorney time to review the evidence, investigate the facts, and explore potential defenses or plea negotiations.
