Terms in the Criminal Legal System

This glossary is intended to provide a brief explanation of words commonly used in the criminal legal system.



A person who knowingly and intentionally helps someone else commit a crime, either before by encouraging the crime or after by concealing the crime.


A person who helps someone else commit a crime. Can be on purpose or not.


When a judge or jury finds that the person on trial is not guilty. An acquittal is not a declaration of the accused’s innocence; it simply means that the judge or jury was not convinced that the defendant was guilty beyond a reasonable doubt.


In general, a final judicial determination of a case.

In Juvenile Court, it means the equivalent of a “conviction” in adult criminal cases, when the court formally takes jurisdiction of the minor due to a plea or a trial verdict.


An explanation by a judge of the charges against a defendant.

  • 1st Advisement: A hearing in which the judge informs a suspect of the charges for which the suspect is being investigated.
  • 2nd Advisement: A hearing in which the judge advises the defendant of the formal filing of charges against him or her.


A person’s written statement of fact or facts made under oath or affirmation in front of someone authorized to administer the oath or affirmation, like a judge or notary public.

A hearing at which the defendant is advised of the charges and the defendant’s rights, and a plea of guilty or not guilty is entered.


Taking custody of a person in order to detain him or her to answer for a criminal charge.

Arrest warrant

A written order issued by a judge based on a sworn affidavit establishing probable cause that an offense has been committed which authorizes a police officer to arrest the suspect.



The amount of money, in cash or secured by property or surety (a third-party guarantor of the amount) required to ensure that a person released from custody after arrest will appear at all future court dates. Bond is set by a judge or magistrate, not the police or the district attorney.

A personal recognizance bond releases a person from custody based on that person’s word that he or she will return to court.

Bail/bond forfeiture

A court order to let the court keep the bail deposit because the defendant failed to appear in court as promised. A cancellation of the bond.

Bench trial

A trial without a jury. The judge or magistrate decides the case. Also known as a “trial to the court.”

Bench warrant

A warrant issued by the court for the arrest of a person for violating the judge’s orders. If a defendant fails to appear for a court appearance as scheduled, a “Failure to Appear” (FTA) warrant is issued by the judge.

Bind over

Finding at a felony preliminary hearing in County Court that probable cause exists to proceed to trial in District Court on the charges filed against the defendant.

Bond reduction or modification hearing

A hearing requested by the defendant or by the prosecution asking the judge to modify, reduce or increase the bond originally set.


The process of formally recording a person’s arrest. Includes taking fingerprints, photographs, and writing down other identifying information about the arrestee.

Burden of proof

The level of proof required to show or prove the facts and elements of a crime against a suspect or defendant. Different burdens of proof exist in the law:

  • Probable cause—a reasonable belief that a person has committed a crime. Level of information needed for arrest. Sufficient facts and circumstances within the officer’s knowledge that are sufficient to warrant a prudent person to believe a suspect has committed a crime.
  • Preponderance of the evidence—the burden of proof in civil cases and in some motions hearings in criminal cases. Evidence which, as a whole, shows that the fact sought to be proved is more probable than not. Something more than 50% of the credible evidence.
  • Clear and convincing—the burden of proof in selected proceedings, such as termination of parental rights. A little more difficult to quantify, but something more than “preponderance” and less than “beyond a reasonable doubt.”
  • Beyond a reasonable doubt—the burden of proof in criminal cases. The degree of belief a juror or judge must have regarding all factual elements of a charged crime.



A dispute between opposing parties resolved by a court, or by some equivalent legal process. A case may be either civil or criminal.

Case number

The number assigned by the court to identify each case. It includes the year in which the case is filed, followed by “CR” for felonies, or “M” for misdemeanors, then followed by numbers indicating the sequence of the case among those cases filed in that particular judicial district: “17CR01235” or “16M04552.”

City Attorney criminal cases will have will have “GS” or “D” in the case number.

Change of venue

The transfer of a case to another jurisdiction. Frequently used in the juvenile court system to refer to the transfer of probation supervision to another jurisdiction.


In criminal law, each crime the defendant is accused of. Also referred to as a “count.”

Charging document

Competency examination

A court-ordered examination of the defendant to determine if they are mentally competent to understand the nature of the criminal trial and to assist their attorney in their own defense. Insanity and competency are two different things. An insane person may still be competent to proceed to trial. All persons found “not guilty by reason of insanity” at trial have been determined competent to stand trial.

Competency hearing

A court-ordered hearing to determine if a defendant is competent to understand the nature of the criminal trial and to assist his attorney in his own defense. The court usually holds the hearing after a psychologist or psychiatrist completes an examination of the defendant.

Deferred judgment

The result of a plea agreement in which a defendant pleads guilty to a crime but is given a chance to avoid a conviction by complying with certain conditions (which are generally similar to those imposed when a defendant is sentenced to probation) for a specified period of time. If the defendant completes the conditions successfully, the judgment of conviction that would normally enter on the defendant’s record after a guilty plea is never entered. If the defendant fails to complete the deferred judgment, then the deferred judgment is generally revoked and a judgment of conviction is entered.

  • Adult direct file—for adults charged with the most serious of felonies, such as homicide, the prosecution may request the case be immediately filed in District Court without first beginning in County Court. Grand Jury indictments are also directly filed in District Court.

Not all felony offenses receive a preliminary hearing.

Pre-sentence investigation (PSI)
