Allege

Allege: To state something as a fact in a court filing, such as a complaint or answer, that the party says it will prove. A statement made this way is an allegation. An allegation is not proof: the court decides whether it is true based on the evidence. Under Federal Rule of Civil Procedure 8(a)(2), a complaint must contain "a short and plain statement of the claim showing that the pleader is entitled to relief," and Rule 9(b) requires a party alleging fraud or mistake to "state with particularity the circumstances constituting fraud or mistake." By signing a filing, a party or lawyer certifies under Rule 11(b)(3) that its factual contentions have evidentiary support or, if specifically so identified, will likely have it after a reasonable opportunity for further investigation or discovery.

What allege means

Put simply, allege is part of the working vocabulary of a civil case. The short definition above covers the usual meaning. Still, a specific rule, statute or contract can give it a narrower meaning. For that reason, check how it is used in your own documents.

Where allege comes up

For example, the term appears in these procedures:

  • Complaint (Fed. R. Civ. P. 3, 8(a)): the pleading that starts a civil action. Under Rule 3, a civil action is commenced by filing a complaint with the court.
  • Answer (Fed. R. Civ. P. 8(b), 12(a)): the defendant's responsive pleading. It admits or denies the allegations of the complaint and states any defenses.

How to research the term

First, read the term where it actually appears. A rule, statute or court decision may define it for its own purposes. Next, check whether your court has a local rule that uses allege in a special way. Then look at recent decisions from courts in your jurisdiction. They show how judges apply the term today. Also, remember that state law can differ from federal law. For that reason, use our state procedures guide to find your state’s rules. Finally, confirm every source is current before you rely on it.
