When the failure to state a claim is used

Timing: usually before the answer. 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

  • A motion asserting a Rule 12(b) defense must be made before pleading if a responsive pleading is allowed.
  • This defense may also be raised later — in a pleading, by a Rule 12(c) motion, or at trial (Rule 12(h)(2)).

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 failure to state a claim 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 failure to state a claim 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.
