The difference between an arraignment and an indictment comes down to what each one is and when it happens. An indictment is a formal written criminal charge handed down by a grand jury. An arraignment is the courtroom hearing where the defendant is told what the charges are and enters a plea. The indictment creates the case; the arraignment opens it in court. One happens in secret without the defendant; the other requires the defendant to be present.
What an Indictment Is
An indictment is a written document that formally accuses someone of a crime. It comes from a grand jury — in the federal system, a group of 23 ordinary citizens who review evidence a prosecutor presents and decide whether there’s enough reason to believe a crime was committed and that the accused is responsible.1Cornell Law School. Indictment The standard they apply is probable cause, a much lower bar than the “beyond a reasonable doubt” standard used at trial. The grand jury isn’t deciding guilt. It’s deciding whether the case is strong enough to move forward.
The Fifth Amendment requires a grand jury indictment for any federal felony.2Constitution Annotated. Amdt5.2.2 Grand Jury Clause Doctrine and Practice Grand jury proceedings are closed. The prosecutor presents evidence and witnesses, but the defendant and defense attorney aren’t in the room and often don’t even know the proceedings are happening.1Cornell Law School. Indictment There’s no cross-examination, no opposing argument, and no judge presiding over the evidence. If at least 12 of the 23 grand jurors agree the evidence meets probable cause, they return a “true bill,” which becomes the indictment.3United States Courts. Handbook for Federal Grand Jurors Because the process is one-sided, grand juries return indictments in the vast majority of cases prosecutors bring to them.
What an Arraignment Is
Once charges have been filed, the defendant must appear in court for an arraignment. This is the first point in the process where the defendant is formally involved. Federal Rule of Criminal Procedure 10 requires that the arraignment take place in open court and do three things: make sure the defendant has a copy of the charges, read or summarize those charges, and ask the defendant to enter a plea.4Legal Information Institute. Federal Rules of Criminal Procedure Rule 10 – Arraignment
The available pleas are not guilty, guilty, or nolo contendere (no contest). A no-contest plea has the same practical effect as a guilty plea for sentencing, but the defendant doesn’t formally admit guilt, which can matter in related civil lawsuits. A no-contest plea requires the court’s approval; the judge must consider the parties’ views and the public interest before accepting one.5Legal Information Institute. Federal Rules of Criminal Procedure Rule 11 – Pleas If a defendant refuses to enter any plea, the court enters a not-guilty plea automatically.
The arraignment is also when the Sixth Amendment right to counsel attaches as a “critical stage” of the prosecution.6Legal Information Institute. Overview of When the Right to Counsel Applies If the defendant can’t afford a lawyer, the court will appoint one.7United States Probation and Pretrial Office. Court Hearings
How the Two Differ
The sequence is always the same. Charges come first, the arraignment follows. You cannot have an arraignment without a charging document already on file.7United States Probation and Pretrial Office. Court Hearings
The differences go beyond timing:
- An indictment happens behind closed doors with only the prosecutor and grand jurors present. The arraignment is public and requires the defendant to appear.
- A grand jury decides whether probable cause exists. A judge presides over the arraignment, and that question is not revisited there.
- The indictment is a written accusation. The arraignment is a hearing that records the defendant’s plea, addresses counsel and bail, and sets the case on a path toward trial or resolution.
- The defendant has no role in the indictment and often no knowledge it is happening. The defendant is the central participant at the arraignment.
Confusing the two is understandable because both involve criminal charges. They sit at different ends of the early process and serve entirely different functions.
Not Every Case Starts With an Indictment
Grand jury indictments are required for federal felonies, but they aren’t the only way criminal charges begin. In roughly half of states, prosecutors can file a charging document called an “information” and then present their evidence at a preliminary hearing before a judge. Even in the federal system, a defendant can waive the right to a grand jury indictment in open court and agree to be charged by information, as long as the defendant is first advised of the charges and their rights.8Legal Information Institute. Federal Rules of Criminal Procedure Rule 7 – The Indictment and the Information
A preliminary hearing works differently from a grand jury in one important way: the defense gets to participate. The defendant can be present, see the prosecution’s witnesses, and cross-examine them. A judge, not a group of citizens, decides whether probable cause exists. Either way — indictment or information — the next step is the same. The defendant is brought to court for an arraignment to hear the charges and enter a plea.
What Else Happens Around the Arraignment
Several things typically fall into place at or near the arraignment that help explain why this hearing matters so much more than the indictment does to the defendant’s day-to-day situation.
Bail and Release Conditions
Bail is usually addressed at or near the arraignment. Under federal law, the default is release. A judge should let a defendant go on personal recognizance (a promise to return) or an unsecured bond unless there’s a specific reason to impose stricter conditions. When a promise isn’t enough to ensure the defendant appears or to protect public safety, the court can add conditions like a cash bond, property forfeiture agreement, GPS monitoring, or travel restrictions. A judge cannot set a financial condition so high that it effectively keeps the defendant locked up before trial.9Office of the Law Revision Counsel. 18 U.S. Code 3142 – Release or Detention of a Defendant Pending Trial The purpose of bail is to guarantee appearance, not to punish someone who hasn’t been convicted.
The Speedy Trial Clock
In federal court, the government has 30 days from arrest or summons to file an indictment or information. If no grand jury is in session during that window, the deadline extends to 60 days. Once charges are filed and the defendant has appeared, the trial must begin within 70 days from whichever event happens last.10Office of the Law Revision Counsel. 18 U.S. Code 3161 – Time Limits and Exclusions Various delays, including time spent on pretrial motions and agreed continuances, are excluded from the count, so complex cases often take much longer in practice. State timelines vary and are governed by each state’s own speedy trial rules.
Discovery
The arraignment also marks the point where evidence starts flowing between the sides. Under Federal Rule of Criminal Procedure 16, the government must turn over categories of evidence on request, including the defendant’s statements to law enforcement, prior criminal record, physical evidence the government plans to use at trial, and reports from scientific tests or expert examinations. Many federal courts have standing discovery orders that make these disclosures automatic. The government also has a continuing duty to turn over additional evidence it discovers later if it falls within the scope of what was already requested.11Legal Information Institute. Federal Rules of Criminal Procedure Rule 16 – Discovery and Inspection This is where the defense gets its first real look at the prosecution’s case, and the strength of that evidence often drives plea negotiations from here forward.
