In a criminal case—especially complex white-collar matters—an indictment, an information, and a complaint all serve the same core purpose: they officially initiate the case, inform the defendant of the charges, and ensure the prosecutor has enough evidence to establish probable cause.
However, the path a case takes depends heavily on whether it is in Federal or State court.
Under the Fifth Amendment, the federal system requires a felony prosecution to begin with an indictment.
The Process: A prosecutor presents evidence to a grand jury—a group of citizens who investigate crimes in secret.
The Result: If the jury finds sufficient cause, they issue an indictment. This acts as a formal "road map" of the criminal charges.
The Reality: While the Framers intended the grand jury to be a buffer against overzealous prosecutors, it is often a low hurdle. Since prosecutors control all evidence and legal instructions shown to the jury, they almost always obtain the indictments they seek.
Like an indictment, an information is a formal charging document. The key difference is that it does not require a grand jury’s vote.
The Process: The document is presented directly to a judicial officer (usually a magistrate judge) who decides if there is probable cause.
Usage: In the federal system, this is often used for misdemeanors or when a felony defendant chooses to waive their right to a grand jury—frequently as part of a plea negotiation.
A complaint is a sworn statement of facts provided by a law enforcement official.
The Purpose: It is designed to establish probable cause quickly so an arrest warrant can be issued.
Temporary Nature: A felony case cannot proceed to trial on a complaint alone. It must eventually be "upgraded" to an indictment or information.

Federal vs. State: A Key Distinctiion
While these terms are used across the country, it is important to note that the process varies significantly by state.
The Preliminary Hearing: Unlike the federal system, many states do not require a grand jury. Instead, a defendant often has the right to a Preliminary Hearing.
Public vs. Secret: While a grand jury is a secret meeting, a Preliminary Hearing is a public proceeding held before a judge. During this hearing, the defense often has the opportunity to see the evidence and cross-examine witnesses before the judge decides if the case (the Information) can move forward.
