In general, arrest warrants and bench warrants do not have an inherent time decay or expiration date in the sense that they automatically become invalid after a certain period. These types of warrants remain active until they are resolved by arrest or other means, such as appearing before a judge or satisfying the conditions of the warrant.

Yet, search warrants, which authorize law enforcement officers to search a specific location for evidence of a crime, typically have a limited duration. The duration of a search warrant is usually specified in the warrant itself and may range from a few days to several weeks, depending on the circumstances of the case and the terms set forth by the issuing judge. Once the specified period expires, the search warrant becomes invalid, and law enforcement officers are no longer authorized to execute the search.

Note that while arrest warrants and bench warrants may not have a time decay or expiration date, law enforcement agencies and courts may prioritize serving warrants based on factors such as the seriousness of the offense, the availability of resources, and the length of time the warrant has been outstanding. Further, individuals with active warrants may be subject to arrest at any time if encountered by law enforcement officers.
