What Is the Difference Between Being Arrested and Being Charged?
Criminal DefenseMost people who call us after a run-in with law enforcement use the words “arrested” and “charged” like they mean the same thing. They don’t. And that distinction, while it sounds like legal hairsplitting, can have real consequences for how your case unfolds in St. Louis City, St. Louis County, or anywhere else in Missouri.
We get this question regularly, and it makes sense why people are confused. Criminal defense law involves a process most people never think about until they’re suddenly in the middle of it. So let’s walk through what each term actually means, how they connect, and why the gap between them matters more than most people realize.
What an Arrest Actually Is
An arrest is an actual restraint or submission to police custody. It typically happens when law enforcement has probable cause to believe you’ve committed a crime, which might stem from direct observation, a police investigation, or a report by someone else. Probable cause means the police have enough evidence to reasonably believe you were involved in criminal activity.
Being taken into custody, handcuffed, transported to a police station, and booked — that’s an arrest. It is not a conviction. It is not even a formal accusation in the legal sense. Being arrested and being charged are two different things. An arrest occurs when law enforcement takes you into custody because they believe you’ve committed a crime. Charges, however, can only come from the prosecutor’s office after reviewing the evidence.
That’s a point worth sitting with for a moment. The police officer who arrests you does not decide whether you get charged. Although many people believe that police decide who will be charged for a crime, that is not the case. Law enforcement officers are responsible for arresting the perpetrator and searching for evidence. State and district attorneys are the ones who decide who will be charged for a certain offense.
What a Formal Charge Means
A charge is a formal accusation filed by a prosecutor claiming that a person has committed a criminal offense. The prosecutor must file a document in court — a Complaint, Information, or Indictment — and there will be a court file, with a case number.
That document is what makes something official. Until it exists, you may have been arrested, but you have not been formally charged. If an arrest is made, the case is handed over to a prosecutor who decides whether to file formal charges, marking the start of the criminal legal process, which includes several key stages: arraignment, pre-trial motions, and potentially a trial.
About that review process — it matters a great deal. After your arrest, the prosecuting attorney reviews the evidence and decides whether to file formal charges. In some cases, charges are filed immediately. In others, charges are upgraded or modified after further investigation. The prosecutor may also decline to file charges due to insufficient evidence. That last scenario — no charges filed — is more common than people expect.
You Can Be Arrested Without Ever Being Charged
This surprises people. It’s possible to be arrested but never charged, or to be charged without being arrested first. Both scenarios happen in Missouri.
Consider a situation where someone is arrested near a scene of suspected criminal activity. The officer has probable cause in the moment. But when the prosecutor reviews the full picture — the evidence, witness accounts, and investigation reports — the case simply doesn’t hold up. No charges get filed. The arrest still happened, but the legal process stops there.
The reverse is also true. A prosecutor can file charges against someone who was never physically arrested. When the charging document is filed, a summons or arrest warrant may be issued. In white-collar cases, tax matters, or complex fraud investigations, this path is actually fairly common.
Your Rights the Moment You Are Arrested
Regardless of whether charges eventually follow, your rights attach the moment you’re taken into custody. Before custodial interrogation, law enforcement generally must inform you of your rights, including the right to remain silent and the right to an attorney. You are also entitled to a fair legal process, including a timely arraignment and the opportunity to be heard in court.
Missouri law requires jails to provide inmates reasonable access to phone services. Use one of them wisely. Calling an attorney before saying anything else is, in our experience, one of the most protective decisions a person can make in that moment.
We encourage clients to reach out early. The hours between an arrest and any formal charging decision are not downtime — they’re an opportunity. An attorney who is engaged early may be able to communicate with the prosecutor’s office before charges are even filed, which can sometimes affect what gets charged and at what level.
What Happens After Charges Are Filed
Once the prosecutor files charges, the process moves into a more structured phase. An arraignment in Missouri is a formal court hearing where the accused is brought before a judge to be informed of the charges filed against them. Court proceedings begin when the charging document is filed, and the judge will explain what crime or crimes the prosecutor has charged you with.
At the arraignment, you’ll be asked to enter a plea. Missouri permits pleas of guilty, not guilty, and not guilty by reason of mental disease or defect.
For felony cases specifically, preliminary hearings are only held for felony cases and involve a judge determining if sufficient evidence exists to proceed with a trial. This is actually a meaningful opportunity. A skilled defense attorney can challenge the prosecution’s evidence at this stage, and in some cases, charges can be reduced or dismissed before the case ever reaches a jury.
The Practical Takeaway
An arrest sets the process in motion. A charge is what formally places you in the criminal justice system with a case number, a court date, and a legal record. In a criminal case, the state has the burden of proving beyond a reasonable doubt that the defendant committed the alleged crime. Defendants are presumed innocent and never have the burden of proving their innocence.
That presumption of innocence is not just a phrase. It’s the legal foundation your defense is built on, from the moment of arrest through every stage that follows.
