Particulars

Detailed, formal, written statement of charges or claims by a plaintiff or the prosecutor given upon the defendant's formal request to the court for more detailed information. A bill of particulars may be used in either criminal defense or in civil litigation. In criminal law, defense attorneys may file a motion requesting a bills of particulars from prosecuting attorneys. However, prosecuting attorneys can not request the same of the defense. This request may be part of an omnibus motion, motion in limine, or similar motion.

In a civil action such as a tort or breach of contract case, either attorney or party can request it. It is rarely used in American small claims cases. It is not entirely clear whether this can be done in practice in Britain on the Allocation questionnaire. An insufficient response to a request for a bill of particulars may be grounds for dismissal of the claim, or other sanctions against the responding party. In civil cases, a bill of particulars is a pleading, which "amplifies" the complaint, but can also act as a discovery device or tool. The bill of particulars was abolished in nearly all U.S. court systems in the 1940s and 1950s due to the widespread recognition that much of the information requested could be obtained more efficiently through the discovery process. Today, only a minority of U.S. states, like New York, use the bill of particulars. The closest modern equivalent, though rarely used, is the motion for a more definite statement.
