The criminal justice process steps run from investigation and arrest to charging, pretrial hearings, a plea or trial, sentencing and appeal. Your first question is whether the case is state or federal, because that decides who prosecutes.
Each branch below shows what changes the path: the level of government, the felony or misdemeanor label, whether the defendant is held, and whether the case ends in a plea or a verdict. Follow the branch that matches your situation, then use the linked guides for detail on a single stage.
Choosing your starting point
A criminal case is better read as a series of branches than as one straight line. Four questions place almost any case on the map, and the answers tell you which sections of this guide matter most.
- State or federal. The U.S. Department of Justice explains that state cases are brought by prosecutors or district attorneys, while federal cases are brought by United States Attorneys. Most local arrests start in the state system. If a federal agency or a federal prosecutor is involved, read the federal stages in the table near the end first.
- Felony or misdemeanor. This label changes the pretrial route. A felony can pass through a preliminary hearing and a grand jury, while a misdemeanor can move straight to a plea hearing. The felony and misdemeanor section below explains the split, and the guide on felony vs misdemeanor goes deeper into examples.
- Held or released. A person held in jail after arrest faces fixed timing rules for seeing a judge. A person who can post bail, or who is released, still follows the same court stages but with less urgency in the first days.
- Plea or trial. Most cases do not reach a trial. The choice between accepting an agreement and going to trial is the biggest fork in the process and gets its own section.
The federal government lists the stages of a federal case as investigation, charging, initial hearing or arraignment, discovery, plea bargaining, preliminary hearing, pretrial motions, trial, post-trial motions, sentencing and appeal. The Justice Department stresses that its list is not exhaustive: some cases are much simpler, and others include more steps. State systems follow a similar outline with their own names and deadlines, so treat the examples here from California, Tennessee, Iowa and Washington as illustrations of common patterns, not a rule for every court.
Lower-level violations raise a separate threshold question. If you are unsure whether a ticket-type offense belongs in this process at all, start with is an infraction a crime before reading further.
Investigation and arrest
Every case begins with an investigation, and the DOJ lists it as the first stage of the federal process. An arrest is the point at which the person suspected of the offense is taken into custody, and it can happen with or without a warrant that a judge has signed beforehand.
A Tennessee district attorneys’ guide defines an arrest warrant as a written order from a judge that a person be arrested. That definition matters because it places a neutral decision-maker before the arrest in the cases where a warrant is used. Beyond that, the supplied court guidance does not describe every circumstance in which police act without one, so check your state’s rules for specific situations.
Time limits on bringing a case also begin to matter at this point. How long prosecutors have to file charges depends on the offense and the jurisdiction, and the guide to the criminal statute of limitations covers that separate question.
If you are the person arrested, the practical priority is the next hearing. The next section explains how quickly it must happen.
After an arrest: the first court appearance and bail
After an arrest, a person who stays in custody must be brought before a judge quickly. The deadline is set by state law, so the number of hours differs by place.
Timing of the first appearance
A county attorney’s office in Iowa states that persons taken into custody must be taken before a judge within 24 hours of arrest. In Washington, Franklin County explains that when a suspect is arrested and held in jail, the preliminary appearance must take place within 72 hours, and that it often happens the next court day. The gap between those two figures is a good reminder that a deadline you read online may not be the one your state applies. Find the rule for the state where the arrest happened.
What bail is
Bail is, in the words of the Tennessee district attorneys, an amount paid or pledged by the defendant to make sure he or she will appear in court. Its purpose is attendance, not punishment. Whether it is set at the first appearance, and how, varies by state, and the full mechanics are covered in how does bail work.
Choosing what to do first
- If you are held in jail. Focus on the first appearance. It is the earliest chance to hear the accusation and to have bail considered.
- If you are released. Treat the release conditions and the next court date as binding, because bail exists to secure attendance.
- If you cannot afford a lawyer. Ask early about court-appointed counsel, and see how to get a public defender for the steps.
Once the first appearance is done, the prosecutor’s charging decision shapes everything else, and that is where the felony-misdemeanor split starts to matter.
Charging, and how felony and misdemeanor cases diverge
Charging is the stage where the prosecutor formally states the accusation. The California courts’ self-help site explains that, typically, the prosecutor files a complaint saying who is accused of a crime, what crime, and when. From here, the route splits.
The preliminary hearing
A preliminary hearing tests whether the case should continue. An Iowa county attorney describes its purpose as determining whether there is sufficient evidence to support the charges against the defendant. California’s courts note that in a felony case there will be a preliminary hearing.
Felony: toward a grand jury
In the Tennessee description, when probable cause is found for a felony, the case is “bound over” to the grand jury. The grand jury is an independent group of private citizens who listen to information about the crime and decide whether the case should go to trial. At the federal level, the Justice Department says indictment by a grand jury is required in federal felony cases unless the defendant waives it. The difference between the two screening bodies is explained in grand jury vs preliminary hearing.
Misdemeanor: straight to a plea hearing
The same Tennessee guide says that when probable cause is found for a misdemeanor, the case goes straight to a plea hearing. A misdemeanor therefore skips the grand jury step entirely, which usually makes the pretrial phase shorter and simpler.
So the answer to the difference between a felony and a misdemeanor, in procedural terms, is the route each takes: a felony passes through a preliminary hearing and then a grand jury, and a misdemeanor goes directly to a plea hearing. Because the label drives so much, it is worth confirming exactly how the prosecutor has charged the case before planning anything else. Ask which offense is named in the complaint and which court will hear it.
Not every step is identical across states. Some states combine or rename hearings, so use these descriptions as a map of the typical order. Victims also have a role at this stage and later ones, which is explained in crime victim rights.
Arraignment and entering a plea
The arraignment is the hearing where the defendant is formally told of the charge and responds to it. Iowa’s county attorney describes it as the formal accusation of the defendant where a plea of guilty or not guilty is entered. California’s court guide adds that defendants at this point find out what they are charged with and what their rights are, and the judge asks whether they are ready to enter a plea.
The federal system treats this as the initial hearing or arraignment. Because the stage combines notice and a first response, it is often the first moment a defendant sits with the full accusation in front of them. For a walk-through of what the hearing looks like, see what is an arraignment.
The decision at this stage is simple to state and hard to make. A not-guilty plea keeps the case moving toward negotiation or trial, and a guilty plea moves it toward sentencing. Before entering either, a defendant benefits from a lawyer’s advice, since a plea affects every later option.
Discovery, motions and alternatives
Between arraignment and trial, the federal list includes discovery, pre-trial motions and plea bargaining. In general terms, these are the stages where each side sees the other’s information and asks the court to rule on legal questions before a jury is ever seated. Some jurisdictions also offer alternatives to the standard path, and what is pretrial diversion explains how those programs fit in.
Plea bargain or trial
This is the largest fork in the process, and the supplied guidance is clear about the likely direction. California’s courts say that most cases do not go to trial, and the defendant may end up making a deal with the prosecution.
Choosing a plea bargain
A plea bargain is an agreement in which the defendant pleads guilty in exchange for something from the prosecutor. The Tennessee district attorneys say the defendant may agree to plead guilty to the crimes charged or to a lesser offense. Franklin County, Washington, adds that the prosecutor may reduce charges or recommend a sentence in exchange for the plea, and that many times the prosecuting attorney will agree to a plea bargain before the trial date. A plea bargain suits a defendant who weighs the strength of the evidence and prefers a more predictable outcome. A full explanation of the trade-offs is in what is a plea bargain.
Choosing a trial
If there is no agreement and the case is not dismissed, California’s guide says it will go to trial, and this is usually a jury trial. In Tennessee, the state must prove beyond a reasonable doubt that the defendant committed the crime, and the defendant chooses between a judge and a petit jury. That burden of proof is the defendant’s main protection, and it is the reason a weak prosecution case can justify a trial over a plea.
A trial has its own internal sequence, covered in stages of a criminal trial. Before it begins, jurors are chosen, and how does jury selection work explains that process.
How to weigh the choice
- Lean toward a plea when the evidence is strong and the offered terms reduce the charge or the recommended sentence.
- Lean toward trial when the prosecution may struggle to meet its burden, or when no acceptable offer has been made.
- Take advice before deciding. A plea is generally final once accepted, so decisions made without a lawyer are the riskiest.
Sentencing
Sentencing follows a guilty plea or a guilty finding. California’s court guide says that if the defendant pleads guilty or is found guilty by a jury, they will be sentenced.
Washington’s Franklin County explains that sentences are given within a standard range based on the crime and the defendant’s criminal history. That means two defendants convicted of the same offense can receive different ranges, so the history matters as much as the charge. Iowa’s county attorney lists the main possibilities: the court may order the defendant to serve jail or prison time, or may suspend the sentence and place the defendant on probation, and fines and restitution may also apply.
Custody, or supervision in the community
- Incarceration. A sentence to confinement is served in a jail or a prison, and the two are not the same. See jail vs prison for the distinction.
- Probation. Tennessee’s district attorneys say probation means the defendant is left free as long as he or she does what the judge has told him or her to do. A violation can put the suspended sentence back in play.
- Parole. Release under supervision after time in custody is a different arrangement from probation, and probation vs parole compares the two.
Financial penalties are easy to overlook. Fines and restitution can accompany any of these outcomes, so a sentence that sounds light may still carry obligations that last well beyond a court date.
Appeals and clearing a record
A conviction is not necessarily the end. California’s court guide says the defendant can try to appeal the decision and that, later, depending on the charges, it may be possible to have their record cleaned.
Appeal
An appeal asks a higher court to review what happened. Tennessee’s district attorneys give a realistic picture: most appeals are unsuccessful, and the process is very lengthy. The federal list also includes post-trial motions before the appeal stage. An appeal is therefore best treated as a narrow remedy for specific legal errors rather than a second chance at a trial.
Cleaning a record
Record relief depends on the charges and the state. The terms are used differently from place to place, so read expungement vs sealing before assuming what a given court will do.
The whole process at a glance
The table lines up the stages in the order a typical case moves through them, with a note on how to use each one when planning your next step.
| Stage | What happens | Planning use |
|---|---|---|
| Investigation | The first stage in the federal list, before any charge is filed. | Seek legal advice early if you know you are involved. |
| Charging | The prosecutor files a complaint stating who is accused, of what crime, and when. | Read the complaint to see whether the offense is a felony or a misdemeanor. |
| Initial hearing or arraignment | The defendant learns the charges and rights, and a plea is entered. | Have a lawyer’s advice before pleading. |
| Discovery and plea bargaining | Information is exchanged, and the prosecutor may offer an agreement. | Compare any offer with the strength of the evidence. |
| Preliminary hearing | A judge checks whether the evidence supports the charges; a felony may then go to a grand jury. | Expect this stage in felony cases, not as a rule for misdemeanors. |
| Pre-trial motions and trial | Legal questions are decided, then the case is usually heard by a jury. | Prepare for a long wait if no agreement is reached. |
| Sentencing | The court imposes a sentence after a plea or guilty finding. | Ask how criminal history affects the standard range. |
| Appeal | A higher court reviews the decision. | Treat it as a lengthy process with uncertain odds. |
The stage list draws on the Justice Department’s overview of the federal criminal process and the California courts’ criminal case overview.
How long it takes
A single case can move quickly or slowly. An Iowa county attorney says that the whole process may take two to six months, or even longer. That is a general expectation, not a promise, and a case that needs a grand jury, many motions or an appeal can run much longer. Plan for delays and keep every court date, since a missed appearance can undo the protection that bail or release provides.
Keeping your own copies of charging papers, hearing notices and orders makes each stage easier to follow, because every one of the steps above produces a record you may need later.
Frequently asked questions
Is bail set in every case?
It depends on the state. Franklin County, Washington, says bail must be set in all cases regardless of the crime committed, while the Tennessee district attorneys note that not every case has a bail hearing.
Can a judge turn down a plea agreement?
Yes. The Tennessee district attorneys’ guide says the judge may accept or reject the agreement, so a deal between the prosecutor and the defendant is not final until the court approves it.
Does the defendant attend the grand jury?
No. The grand jury is an independent group of private citizens who hear information about the crime and decide whether the case should go to trial, and the defendant is not present while they do.
