The criminal defense process is an ordered sequence of stages, beginning at arrest and moving through charging, arraignment, discovery, possible trial, sentencing, and appeals. Understanding where you stand in that sequence, and what decisions each stage demands, is the first practical step toward protecting your rights.
The main stages, as summarized by the Bureau of Justice Statistics, follow this order:
- Arrest, booking, and initial appearance
- Charging (complaint, information, or grand jury indictment)
- Arraignment and entering a plea
- Discovery and pretrial motions
- Plea negotiations
- Preliminary hearing or grand jury (where applicable)
- Trial (jury selection through verdict)
- Sentencing
- Appeals and post-conviction remedies
Approximately 90–97% of criminal cases resolve through plea negotiations rather than at trial. That figure shapes every strategic decision a defense attorney makes, from the first bail hearing to the final pretrial motion.

What happens at arrest, booking, and your first court appearance?
Arrest is the system’s first contact with a defendant, and the decisions made in the first 24–72 hours can affect the entire case. When law enforcement takes you into custody, they transport you to a booking facility where officers record your fingerprints, photograph you, and run a criminal history check. That record follows the case from that point forward.
Miranda warnings apply once you are in custody and subject to interrogation. You have the right to remain silent and the right to have an attorney present during questioning. Invoking those rights clearly and calmly, stating “I am invoking my right to remain silent and my right to counsel,” stops the interrogation. Anything said before or after that invocation can be used against you, so the practical rule is simple: say nothing substantive until you have spoken with an attorney.
The initial appearance typically occurs within 24–72 hours of arrest. A magistrate judge or judge informs you of the charges, advises you of your rights, and makes a bail determination. Bail options include:
- Cash bail: You pay the full amount to the court; it is returned at case resolution if you appear.
- Surety bond: A bail bondsman posts the amount for a non-refundable fee, typically 10% of the bail amount.
- Own recognizance (OR) release: The judge releases you on your promise to appear, without financial conditions.
- Pretrial detention: The judge finds you a flight risk or danger to the community and holds you without bail.
Release conditions can also include electronic monitoring, travel restrictions, no-contact orders, or mandatory check-ins with a pretrial services officer.
Pro Tip: Pretrial detention is not just uncomfortable, it is strategically damaging. Detained defendants have less access to their attorneys, less time to gather evidence, and face greater pressure to accept unfavorable plea offers. Retaining counsel before or immediately after the initial appearance gives your attorney the best chance to argue for release or reduced conditions.
Practical immediate steps: ask for counsel by name or request a court-appointed attorney, avoid making any detailed statements to officers or other inmates, document the names of any witnesses present, and contact a family member or employer who can assist with bail.
How formal charges are filed: complaint, information, and indictment
Arrest does not equal formal charges. Before the prosecution can proceed, a court or grand jury must independently determine that probable cause exists to charge you with a crime.
Three mechanisms bring formal charges:
- Criminal complaint: A sworn statement by law enforcement or a prosecutor alleging probable cause; used to initiate proceedings and support an arrest warrant, but not a final charging document.
- Information: A formal charging document filed directly by the prosecutor after a preliminary hearing establishes probable cause; common in state misdemeanor and felony cases in many jurisdictions.
- Grand jury indictment: A secret proceeding in which the prosecutor presents evidence to a panel of citizens; if at least 12 grand jurors agree probable cause exists, they issue an indictment.
State vs. federal charging: key differences
| Feature | Federal Cases | State Cases |
|---|---|---|
| Who prosecutes | U.S. Attorneys | State/county prosecutors |
| Charging mechanism | Grand jury indictment required for felonies | Information or preliminary hearing common |
| Grand jury | Required for federal felonies (5th Amendment) | Optional or not used in many states |
| Preliminary hearing | Less common; grand jury substitutes | Frequently used to establish probable cause |
| Discovery timeline | Governed by federal rules (Brady, Jencks Act) | Varies by state statute |
Federal criminal cases are brought by U.S. Attorneys and typically require a grand jury indictment for felony charges. State systems vary considerably: some states use grand juries regularly, while others rely almost entirely on informations and preliminary hearings. That distinction matters because grand jury proceedings are secret, you generally cannot attend or present evidence, and the indictment itself signals that the prosecution has already built a presentable case. A state information, by contrast, is tested at a public preliminary hearing, where your attorney can cross-examine witnesses and challenge probable cause.
The charging mechanism also affects discovery timelines and available defenses. Federal cases carry specific disclosure obligations under the Brady doctrine and the Jencks Act; state rules differ. Consulting an attorney experienced in the specific jurisdiction is not optional, it is necessary.
What arraignment means and why your plea choice matters
Arraignment is the hearing at which formal charges are read to you in open court. The judge recites your rights, sets future hearing dates, and asks you to enter a plea. The entire proceeding often takes less than 15 minutes, but the plea you enter has lasting consequences.
Common plea options:
- Not guilty: You deny the charges. This is the standard arraignment plea and preserves all defense options, including motions, negotiations, and trial.
- Guilty: You admit to the charges as stated. Sentencing typically follows, either immediately or at a later hearing.
- No contest (nolo contendere): You accept the criminal penalty without admitting guilt. This plea cannot be used as an admission in a related civil lawsuit, which makes it strategically useful in certain cases.
- Plea open: You plead guilty without a negotiated agreement, leaving sentencing entirely to the judge’s discretion. This is a high-risk option that eliminates any guaranteed sentence recommendation from the prosecutor and should only be considered after thorough counsel consultation.
Pleading guilty at arraignment without first reviewing discovery, consulting counsel, and exploring all defenses is one of the most consequential mistakes a defendant can make. Charges are sometimes reduced, evidence is sometimes suppressed, and cases are sometimes dismissed entirely during the pretrial phase. A not-guilty plea at arraignment costs nothing and preserves every option.
Defendants almost universally plead not guilty at arraignment, even when they ultimately intend to negotiate a plea deal. The not-guilty plea simply keeps the case open while the defense investigates, reviews evidence, and evaluates the prosecution’s actual strength.
Discovery, pretrial motions, and plea negotiations: where most cases are decided
Discovery and pretrial motions are the practical battleground of criminal defense. Most cases are won, reduced, or resolved here, not at trial.
What discovery includes:
- Police reports and incident narratives
- Body camera and surveillance footage
- Lab results (DNA, toxicology, forensic analysis)
- Phone records, GPS data, and digital evidence
- Witness statements and prior criminal records of prosecution witnesses
- Any evidence favorable to the defense (Brady material)
The prosecution has a constitutional obligation to disclose evidence that is material to guilt or punishment. Failure to disclose exculpatory evidence is a Brady violation and can result in dismissal or reversal of a conviction.
Key pretrial motions:
- Motion to suppress: Challenges evidence obtained through an unlawful search, seizure, or interrogation. If granted, that evidence is excluded from trial, which can gut the prosecution’s case.
- Motion to dismiss: Argues the charges lack legal or factual basis, or that the defendant’s rights were violated.
- Brady request: Formally demands disclosure of all exculpatory and impeachment evidence the prosecution holds.
Motions to suppress are often case-dispositive. When a court excludes critical evidence, prosecutors frequently offer significantly better plea terms or drop charges entirely rather than proceed to trial with a weakened case.
Pro Tip: Discovery review is not passive. Ask your attorney specifically which witnesses the prosecution intends to call, whether any lab results are contested, and whether any search or seizure in your case was supported by a valid warrant. Those questions often surface the motion arguments that change outcomes.
Plea negotiations typically intensify after discovery closes and pretrial motions are resolved. The defense’s leverage in those negotiations comes directly from the strength of its motions and the weaknesses it has identified in the prosecution’s evidence. A well-timed motion to suppress can shift a felony offer to a misdemeanor, or a misdemeanor offer to a dismissal. For a deeper look at building that kind of leverage, Narolaw’s guide on effective defense strategy walks through the motion and negotiation process in New Hampshire specifically.
Preliminary hearings and grand jury: when each applies
Both the preliminary hearing and the grand jury serve the same threshold function: determining whether probable cause exists to proceed to trial. Which one you face depends on jurisdiction and the nature of the charges.
Preliminary hearing
A preliminary hearing is a public court proceeding before a judge. The prosecutor presents evidence and witnesses; your attorney can cross-examine those witnesses and challenge the sufficiency of the evidence. If the judge finds probable cause, the case proceeds. If not, charges are dismissed, though the prosecution can often refile.
Defendants in many state systems have the right to a preliminary hearing but may waive it strategically. Waiving can make sense when the defense does not want to tip its hand before trial, or when the hearing would expose a key defense witness to early cross-examination.
Grand jury
Grand juries operate in secret. The prosecutor presents evidence without the defense present, and grand jurors decide whether to issue an indictment. You may choose to testify before the grand jury, but anything you say can be used against you at trial, and you cannot have your attorney in the grand jury room during testimony (though you may leave to consult with counsel outside).
| Scenario | Likely Process |
|---|---|
| Federal felony charge | Grand jury indictment required |
| State felony, grand jury state | Grand jury or preliminary hearing |
| State felony, non-grand jury state | Preliminary hearing or information |
| State misdemeanor | Information; preliminary hearing less common |
| Defendant waives preliminary hearing | Case proceeds directly to arraignment/trial |
The strategic implications differ sharply. A preliminary hearing gives the defense an early look at prosecution witnesses and their testimony under oath. A grand jury gives the defense nothing, since proceedings are sealed. In federal cases, where grand jury indictments are the standard path for felonies, defense strategy shifts to discovery and suppression motions rather than the preliminary hearing stage.
The six phases of a criminal trial and what the defense does at each one
Only a small percentage of cases, approximately 3–10%, actually reach trial. When they do, the trial unfolds in six defined phases.
1. Jury selection (voir dire)
The judge and attorneys question prospective jurors to identify bias. The defense uses two types of challenges: challenges for cause (unlimited, based on demonstrated bias) and peremptory strikes (limited in number, no reason required, subject to constitutional limits). The goal is a jury that will apply the burden of proof fairly.
2. Opening statements
The prosecutor goes first, outlining what the evidence will show. The defense follows, previewing the weaknesses in the prosecution’s case and the theory of defense. The defense may reserve its opening until after the prosecution rests, though this is uncommon.
3. Prosecution’s case-in-chief
The prosecutor calls witnesses and introduces physical evidence. The defense cross-examines each witness, challenging credibility, inconsistencies, and the reliability of forensic evidence. Motions in limine, filed before trial, can exclude prejudicial or inadmissible evidence before the jury ever hears it.
4. Defense case and rebuttal
The defense is not required to present any evidence. The defendant has an absolute right not to testify, and the jury cannot hold that silence against them. If the defense does present witnesses or evidence, the prosecution may offer rebuttal evidence in response.
5. Closing arguments
Both sides summarize the evidence and argue their interpretation. The prosecutor speaks first and last. The defense uses closing argument to highlight reasonable doubt, attack the credibility of key prosecution witnesses, and reinforce the burden of proof.
6. Jury instructions, deliberation, and verdict
The judge instructs the jury on the applicable law, including the definition of each charged offense and the standard of proof. The jury deliberates in private. Under federal rules and most state systems, a guilty verdict must be unanimous. If jurors cannot agree, the judge may declare a mistrial, and the prosecution can retry the case.
The burden of proof rests entirely on the prosecution. Proof beyond a reasonable doubt is the highest standard in American law. The defense does not need to prove innocence; it needs only to create genuine doubt.
Defendants may also waive the right to a jury trial and request a bench trial, in which the judge decides guilt. Bench trials are relatively rare but can be advantageous when the facts are legally complex or when local jury sentiment is a concern.
Sentencing and what comes after a conviction
Sentencing follows a guilty verdict or a guilty plea. In most jurisdictions, a presentence investigation report (PSI) is prepared before the sentencing hearing. The PSI details the defendant’s criminal history, personal background, employment, family circumstances, and the impact on any victims. Judges rely heavily on the PSI when determining the sentence.
The PSI can be prepared before the sentencing hearing or, in some jurisdictions, at the plea hearing itself. Your attorney should review the PSI carefully and correct any factual errors before it reaches the judge.
Possible sentencing outcomes include:
- Incarceration (jail for misdemeanors, prison for felonies)
- Probation (supervised release in the community with conditions)
- Fines and restitution to victims
- Community service
- Diversion programs or treatment-based alternatives
- A combination of the above
Parole vs. supervised release: Parole is a discretionary early release from prison granted by a parole board, common in state systems. Federal courts use supervised release, a term of community supervision that follows a prison sentence and is set by the sentencing judge, not a board.
Post-conviction remedies:
- Direct appeal: Filed in the appellate court, challenging legal errors made at trial or sentencing. An appeal is not a new trial; it reviews the record for errors of law. Grounds include improper jury instructions, admission of unlawful evidence, or ineffective assistance of counsel.
- Habeas corpus: A federal remedy available after state appeals are exhausted, challenging the constitutionality of the conviction or sentence.
- Expungement and record sealing: Available in some jurisdictions for certain offenses after completing a sentence; eligibility rules vary significantly by state.
- Diversion and deferred sentencing: Some defendants, particularly first-time offenders, may qualify for programs that result in dismissal upon successful completion.
Preserving issues for appeal begins at trial, not after conviction. Your attorney must object to errors on the record at the time they occur; failing to object typically waives the issue on appeal.
How long does a criminal case take, and how do most cases resolve?
Setting realistic expectations about timeline and outcome is one of the most practical things a defendant can do early in a case.
Approximately 90–97% of criminal cases resolve through plea negotiations. That means the overwhelming majority of defendants never face a jury. The strategic implication is that preparing for trial, filing strong motions, and building a credible defense is often a tool to improve plea terms rather than a path to a jury verdict.
| Case Type | Typical Timeline | Most Common Resolution |
|---|---|---|
| Simple misdemeanor | 2–6 months | Plea agreement or dismissal |
| Complex misdemeanor | 6–12 months | Plea agreement |
| State felony (non-complex) | 6 months | Plea agreement |
| Complex felony | 1–3 years | Plea agreement or trial |
| Federal felony | 1–3+ years | Plea agreement |
Several factors extend timelines: the complexity of the evidence, the number of co-defendants, the court’s docket, continuances requested by either side, and the time required for forensic testing. Federal cases tend to run longer than state cases because of more extensive discovery obligations and more complex charging documents.
The practical meaning for defendants: do not assume a case will resolve quickly, and do not assume it will go to trial. Most cases land somewhere in the middle, resolved through negotiation after months of pretrial work.
What your criminal defense attorney actually does, and questions to ask
A criminal defense attorney’s role extends well beyond courtroom appearances. Understanding what counsel does at each stage helps you evaluate representation and participate meaningfully in your own defense. Knowing how much an attorney affects your case is itself a reason to retain experienced counsel early.
Attorney tasks by stage:
- Arrest/booking: Advises on invoking rights; contacts family; begins bail advocacy.
- Initial appearance: Argues for release or reduced bail conditions; challenges detention.
- Charging: Reviews the charging document for legal sufficiency; identifies jurisdictional issues.
- Discovery: Requests all evidence; reviews police reports, lab results, and digital records; identifies Brady material.
- Pretrial motions: Files motions to suppress, dismiss, or compel disclosure; argues hearings.
- Plea negotiations: Evaluates offers against likely trial outcomes; advises on risks and benefits of each option.
- Trial preparation: Prepares cross-examination, selects expert witnesses, drafts motions in limine.
- Sentencing: Reviews the PSI; presents mitigating factors; argues for the lowest appropriate sentence.
- Appeals: Preserves issues on the record; files timely notices of appeal; identifies legal errors.
What to bring to a first consultation:
- Any charging documents, summons, or arrest paperwork you have received
- A written timeline of events as you remember them
- Contact information for any witnesses
- Any physical evidence or documentation relevant to the incident
- Questions about fees, representation agreements, and expected timelines
Questions to ask prospective counsel:
- How much of your practice is criminal defense, and in which courts do you regularly appear?
- Have you handled cases with charges similar to mine?
- What is your assessment of the prosecution’s likely evidence?
- What is the realistic range of outcomes, and what factors drive each?
- How will you communicate with me, and how often?
- What are your fees, and what does the representation agreement cover?

The part of this process most people underestimate
Most people facing charges focus on the trial. They picture a courtroom, a jury, a verdict. The reality is that the trial is the least likely outcome in any criminal case, and preparing for it is usually a means to a different end.
The cases I have seen resolved most favorably for defendants share a common thread: the defense attorney used discovery and pretrial motions aggressively, found the weaknesses in the prosecution’s evidence early, and used those weaknesses as leverage in negotiations. A suppressed statement, an excluded lab result, a credibility problem with a key witness, these are the things that move prosecutors toward better offers or dismissals. The courtroom drama most people expect is, in practice, the backstop, not the primary strategy.
What defendants often miss is that the timeline itself is a strategic variable. A case that moves quickly may not give the defense enough time to review discovery thoroughly or develop a suppression argument. Patience, combined with a clear-eyed assessment of the evidence, usually serves defendants better than urgency. The goal is the best outcome, not the fastest one.
