What Is a Criminal Complaint?

A criminal complaint is a court document filed that accuses or charges a suspect with committing a crime. Criminal complaints are usually filed by the prosecutor in cooperation with the police. Sometimes the victim of a crime will individually file a criminal complaint against a suspect.  In many instances, criminal trials start with the filing of the complaint.

An arrest does not begin a formal criminal proceeding. The filing of a criminal complaint is required for the criminal process to begin. Unlike civil complaints, criminal complaints always are filed by the government or the prosecutor of the state who is bringing the charges.

Who Files a Criminal Complaint?

Unlike civil complaints, a criminal complaint is filed by the government of the state that the charges are being brought in. A state prosecutor begins the process after an arrest by the police and presents the case to the prosecution. The prosecution than looks over the police report and determines whether there are enough evidence to bring criminal charges against the prosecutor.

An arrest does not always mean that charges will be filed because the prosecution may determine that there is not enough evidence to bring formal charges against the defendant and may not file a criminal complaint in criminal court. Once the prosecutor files a criminal complaint with the criminal court, then the legal process begins.
