A search warrant authorizes law enforcement officers to search a place or person and to seize evidence. A search warrant must contain (1) a particularized description of the place and person to be searched; (2) a particularized description of the thing or things to be seized; and (3) probable cause for the search and seizure.. An affidavit, which is a sworn statement under oath, lists the facts and circumstances believed to establish probable cause.
Provide a particularized description of the place or person to be searched. Examples include a house at a street address or a specific vehicle.
Provide a particularized description of the things to be seized. Examples include stolen televisions or weapons. A description such as "illegal materials" is too vague.
