The arrest warrant a judge issues from the bench when a defendant misses a court date or violates a court order - what it authorises, the separate failure-to-appear charge and bond forfeiture that often follow, and how a person clears one by surrendering on their own terms rather than being picked up.
A bench warrant is issued by a judge, on the court's own motion, when a person under the court's authority fails to do what the court ordered: most often failing to appear for a scheduled hearing, but also failing to pay a fine, complete a programme, comply with a subpoena, or appear for jury duty. Unlike an arrest warrant, it does not rest on probable cause that a new crime was committed; the authority is the court's power to compel attendance and punish contempt. Once issued it is entered in the state and, for serious cases, national warrant databases, and any officer who encounters the person - at a traffic stop, an airport, a routine record check - may arrest and hold them until they are brought before the issuing court. A bench warrant does not expire.
Missing court has consequences beyond the warrant. In most states failure to appear on a criminal case is itself a crime, graded according to the seriousness of the underlying charge, and it can be prosecuted even if the original case is later dismissed. If the defendant was released on bail, the court forfeits the bond, a surety who posted it may pursue the defendant and any co-signer for the full amount, and release on the same terms is unlikely a second time. A driver's licence may be suspended for failing to appear on a traffic matter. The court may also proceed in the defendant's absence in some circumstances, and a defendant who absconds mid-trial can be tried and sentenced without being present.
Clearing a warrant is done by appearing. A person who learns of one may, with a lawyer, file a motion to recall or quash it and ask for a hearing date, or surrender at the courthouse at a time when the judge is sitting so that the appearance, the explanation and a new release decision happen the same day; a self-surrender arranged in advance is treated very differently from an arrest on the roadside at night, and in many courts a good reason - hospitalisation, a notice sent to a wrong address, incarceration elsewhere - persuades the judge to reinstate the prior release. Ignoring a warrant in the hope it will lapse is the one strategy that never works.
A lawyer can usually clear a bench warrant faster and more safely than the person can alone - by filing a motion to recall it, arranging a walk-in surrender at a time the judge is available, and presenting the reason for the absence with documents - and can sometimes have the failure-to-appear charge dropped as part of resolving the underlying case. Anyone who has missed a date should call a lawyer or the clerk that day: the difference between a warrant recalled at a scheduled hearing and an arrest on a Friday night with a weekend in custody is entirely a matter of who moves first.
Choose your state. Each link opens the directory page for the city in that state with the most currently published law firms in this practice area; a +n beside the city is how many other cities in the state also have one. The list is generated when this page loads, so a state whose listings have lapsed drops out rather than becoming a dead link.
