Motion for Bill of Particulars

In criminal cases, asks the court to require more detail about vague or broad charges.

Governing rule
Fed. R. Crim. P. 7(f)
Read the rule

What it is

A criminal defense motion asking the court to require the government to provide more detail about the charges. It is not full discovery; it clarifies the indictment enough for defense preparation and protection against surprise or double jeopardy.

When it's used

Filed when an indictment or information is broad, vague, or leaves the defendant unable to understand the specific conduct the government will try to prove.

What the other side does

The government argues the indictment, discovery, and other disclosures already provide enough detail and that the defense is seeking an improper preview of trial evidence.

Common outcomes

The court may deny the motion, order limited particulars, or require targeted clarification about dates, transactions, participants, or overt acts.
