Facing a criminal charge can be confusing and frightening. You may wonder what happens next, whether you need a lawyer, and what it will cost. In Missouri, a criminal defense attorney guides you through every step — from your first court appearance to the final outcome.
This guide explains what a defense attorney does, what to expect at each stage of the process, and how to make clear decisions about your case. For a full breakdown of attorney fees specifically, see our complete guide to criminal defense attorney fees in Missouri.
What Does a Criminal Defense Attorney Do?
A criminal defense attorney’s job is to protect your rights and guide you through the legal process from the moment you’re charged to the final resolution of your case.
That work covers several distinct functions. Your attorney reviews the charges filed against you and examines how the evidence was gathered — including whether the police followed legal rules during any traffic stop or search. If they didn’t, your lawyer can file motions to have that evidence excluded. They’ll explain your rights in plain terms, including your right to remain silent and your right to counsel under the U.S. Constitution, so you avoid mistakes that could hurt your case later.
From there, the attorney builds a defense strategy based on the actual facts — finding alibi witnesses, questioning the accuracy of a breathalyzer in a DUI case, or identifying errors in how evidence was handled. Most criminal cases never reach a jury trial. Your lawyer will negotiate directly with the prosecutor, and in many cases, those conversations produce reduced charges or a plea agreement that avoids the worst outcomes.
If your case does go to court, your attorney represents you at every hearing — bail review, arraignment, pretrial motions, and trial itself. They question witnesses, present evidence, and argue legal points on your behalf. Throughout all of it, they keep you informed: explaining what’s happening at each stage, laying out your options, and making sure you understand what decisions need to be made before they’re made.
Why You Should Consider a Lawyer — Even for Minor Charges
In Missouri, even a charge that seems minor can carry consequences that follow you for years. A defense attorney helps you avoid the mistakes — missed deadlines, inadvertent admissions, overlooked negotiation opportunities — that turn manageable situations into serious ones.
The legal process involves rules and deadlines most people don’t know about. Miss a filing window, and you may lose the ability to challenge certain evidence. Answer a police officer’s questions without counsel, and something you said helpfully can appear in court in a different light. Accept a plea without legal advice, and you may not realize you’ve waived your right to appeal or missed a chance at a better offer.
For charges like a first-offense DUI, the stakes include jail time, license suspension, and fines — plus Missouri’s administrative license rules that run parallel to the criminal case. For drug possession, the details of how the evidence was found can change the outcome entirely. For assault or property crimes, a lawyer can often negotiate a lesser charge that keeps a conviction off your permanent record.
The goal isn’t always a not-guilty verdict. Often it’s probation instead of jail, a misdemeanor instead of a felony, or a diversion program that leaves your record clean. A defense attorney knows what’s realistic in your jurisdiction and fights for it.
The Criminal Case Process: From Arrest to Resolution
Understanding the stages of a criminal case helps you know what your attorney is doing at each step and what decisions will be yours to make along the way.
After an arrest and booking, you have the right to remain silent and to ask for a lawyer immediately. Use it — before answering any police questions. Your attorney can be present for any interview or interrogation.
The initial court appearance (arraignment) usually happens within a day or two of arrest. The judge tells you the official charges and takes your plea — typically “not guilty” at this stage. Your defense attorney will be there to enter that plea, argue for reasonable bail, and assess conditions for release. For a detailed walkthrough of what happens in the critical period after a charge, see our post on what happens after a criminal charge in Missouri — your first 72 hours.
During the pretrial phase, both sides exchange information. Your attorney reviews the prosecution’s evidence and files any necessary motions — for example, to suppress evidence obtained through an illegal search or an improper stop. These motions can change the entire shape of a case.
Plea negotiations happen throughout but intensify before trial. Your attorney meets with the prosecutor to explore whether charges can be reduced, dropped, or resolved through a plea to a lesser offense. Most Missouri criminal cases are resolved this way — not because defendants are guilty, but because negotiations produce outcomes better than what a trial might risk.
If no agreement is reached and you maintain a not-guilty plea, the case goes to trial. Your attorney prepares your defense, identifies witnesses, and contests every weak part of the prosecution’s case before a judge or jury. At sentencing, if a conviction results, the attorney argues for the lightest possible outcome — probation, reduced fines, or a treatment program rather than incarceration. If something went legally wrong at trial, an appeal may be an option.
Common Charges and How Defense Attorneys Handle Them
The defense strategy for any charge begins with the specific facts — how evidence was gathered, what can be challenged, and what outcomes are realistically available in your jurisdiction.
For DWI/DUI charges, attorneys examine the traffic stop itself, the administration of field sobriety tests, and whether the breathalyzer was properly maintained and operated. An improper stop can invalidate everything that followed. Even when the stop was legal, an attorney can negotiate to protect your driving privileges and reduce the charge’s long-term impact on your record. Brandt Law handles DWI and traffic defense across Franklin, Crawford, Warren, and Gasconade counties — see our traffic and DUI defense page for more detail.
For drug possession charges, the central question is almost always how the drug was found. If police lacked probable cause for the search — no valid traffic violation, no warrant — the evidence may be suppressible. Without that evidence, prosecutors often can’t proceed. Even when the search was lawful, the type and quantity of the substance, your prior record, and available diversion programs all shape what outcomes are possible.
For assault charges, the facts matter enormously. Was the contact accidental? Was it in self-defense? Did it meet the legal definition of assault under Missouri law? A defense attorney clarifies those questions, and in many cases can negotiate to a non-criminal outcome or a lesser charge. Brandt Law has published a detailed guide to assault charges in Washington County, MO that covers definitions, penalties, and defense strategies specifically.
For theft and property crimes, the value of what was involved determines whether the charge is a felony or a misdemeanor — and that line significantly affects potential penalties. Attorneys often negotiate restitution agreements that result in reduced or diverted charges, keeping a conviction off your record entirely.
For serious felonies — robbery, burglary, violent offenses — the stakes and the work both increase substantially. The attorney investigates the crime scene, identifies alibi witnesses, challenges unreliable testimony, and ensures every element of the charge is genuinely proven before conviction becomes possible.
What Does Criminal Defense Actually Cost?
Criminal defense fees in Missouri depend on the charge, the complexity of the case, and whether the matter resolves through negotiation or goes to trial — but understanding the structure before you hire is the most important step.
Attorneys typically charge either a flat fee (a set price for the case or specific stages) or an hourly rate (billed against a retainer as work is done). Flat fees are more common for straightforward misdemeanor cases. Hourly billing is more common for complex felonies where the total work is harder to estimate upfront. Some attorneys use a tiered structure — one amount for early stages, an additional amount if the case goes to trial.
The factors that drive cost up include the seriousness of the charge, the volume of evidence, whether a trial is likely, and the attorney’s experience.

If you cannot afford a private attorney, Missouri courts may appoint a public defender for serious charges. Public defenders are licensed attorneys who handle criminal cases competently — the practical difference is caseload. A public defender managing many cases simultaneously may have less time for your matter than a private attorney whose schedule is dedicated to it. Either way, having representation matters. Proceeding without any attorney in a criminal case carries significant risk.
Questions to Ask When You Meet With a Criminal Defense Lawyer
A first meeting with a defense attorney is your opportunity to evaluate fit, understand the strategy, and get clear on fees before committing to anything.
Ask about their experience with cases like yours specifically — not just criminal defense generally. Ask whether they’ve practiced in the county where your case is filed, since local knowledge of judges and prosecutors matters. Ask exactly how fees are structured, what’s included, and what happens if the case takes longer than expected. Ask who you’ll communicate with directly and how often.
Ask what the attorney would do first in your case — a clear, confident answer is a good sign. Ask about the range of realistic outcomes: what does a good result look like, what does a bad one look like, and what does it depend on? An honest attorney won’t promise a specific outcome, but they should be able to describe what variables matter most.
Frequently Asked Questions
Do I have to go to court if I hire a lawyer?
For most criminal charges, yes — you’ll still attend key hearings, including arraignment and any trial. Your attorney handles all the speaking and procedural work, which makes those appearances significantly less stressful. In limited circumstances on minor matters, an attorney of record may appear on your behalf without you present — your attorney will tell you when that’s possible.
If I’m innocent, do I still need a lawyer?
Yes. The truth is not self-presenting in a courtroom — it has to be presented correctly, within the rules of evidence and procedure. An attorney ensures that illegal evidence is excluded, that witnesses are properly cross-examined, and that the prosecution is actually required to prove every element of the charge. Representing yourself in a criminal case is almost always riskier than having counsel, regardless of guilt or innocence.
What if I plead guilty without consulting a lawyer?
A guilty plea is a serious, often irreversible decision. You typically waive your right to appeal once you plead. You may also be accepting penalties that could have been negotiated down, or pleading to a charge that could have been dismissed. Even a brief consultation before any plea is strongly advisable — what you learn in that conversation could change the outcome significantly.
Can my charge be dismissed?
It depends on the facts. If the evidence was illegally obtained, if key witnesses are unreliable, or if the prosecution can’t meet its burden of proof, dismissal is possible. A defense attorney will look for every available basis to challenge the charge. Complete dismissal isn’t guaranteed — but a lawyer will find every opportunity that exists and pursue it.
Can my criminal record be cleared after a conviction?
Missouri’s expungement law allows certain convictions and arrest records to be cleared after a waiting period, depending on the offense. Not all charges are eligible. Brandt Law handles expungement as part of its criminal defense services — contact us to find out whether your record qualifies.
What’s the first thing I should do after being charged?
Stay calm. Write down everything you remember about the incident — where you were, what was said, what happened. Don’t discuss the case with anyone other than your attorney. Then contact a criminal defense lawyer as soon as possible. Early action protects your rights from the start and gives your attorney the most time to work with.
