Declaration
Declaration: A written statement of facts signed under penalty of perjury. In federal matters, 28 U.S.C. § 1746 allows an unsworn declaration in place of an affidavit in many situations.

What declaration means
In practice, you will see declaration in pleadings, motions, orders and court rules. The definition above explains the general meaning. Even so, the meaning can shift with context. Therefore, always read it alongside the rule or document where it appears.
Where declaration comes up
For example, the term appears in these procedures:
- Request to Defer Summary Judgment for More Discovery (Fed. R. Civ. P. 56(d)): a request, supported by affidavit or declaration, explaining that the nonmovant cannot yet present facts essential to justify its opposition.
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 declaration 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.
