An arrest warrant is a court order authorizing law enforcement to take a named person into custody.
In plain language, it is judicial permission to arrest someone based on a showing that the legal standard for arrest has been met. It is not the same as a conviction, and it does not decide whether the person is guilty.
Why it matters
An arrest warrant matters because it connects police action to court oversight. The warrant can affect when and how a person is arrested, what happens at the first court appearance, and whether later arguments focus on probable cause or procedural defects.
It also helps separate an accusation from proof. A warrant may allow custody, but the prosecution still must prove the criminal charge through the required process.
Where it appears
Arrest warrants appear in criminal complaints, grand-jury cases, failure-to-appear situations, police records, extradition matters, and first-appearance hearings.
Practical example
A judge reviews a sworn complaint alleging facts that support a felony charge. If the judge finds probable cause, the judge may issue an arrest warrant for the named person.
How it differs from nearby terms
An arrest warrant differs from a search warrant. An arrest warrant authorizes taking a person into custody. A search warrant authorizes a search of a place, item, device, or record.
It also differs from bail, which concerns release conditions after arrest or appearance.
