When the motion for a more definite statement is used
Timing: before filing a responsive pleading. These motions usually come early, often before or with the answer. As a result, they can end or narrow a case before discovery starts.
What the rule requires
- The motion must be made before filing a responsive pleading and must point out the defects complained of and the details desired (Rule 12(e)).
In practice, read each requirement closely. Then check whether your court adds anything of its own. For example, many courts set page limits, formatting rules or a duty to confer with the other side first.

The motion for a more definite statement in state court
State courts follow their own rules of procedure. Many states model their rules on the federal rules, so you will often find a similar motion for a more definite statement procedure. However, the name, the deadline and the required form can differ. Therefore, look up the matching rule in your state’s rules of civil procedure. Also read your court’s local rules. Our state procedures guide links to each state’s official rules.
