Sworn declaration
（重定向自Sworn statement）
A sworn declaration (also called a sworn statement or a statement under penalty of perjury) is a document that recites facts pertinent to a legal proceeding. It is very similar to an affidavit, but unlike an affidavit, it is not witnessed and sealed by an official such as a notary public. Instead, the person making the declaration signs a separate endorsement paragraph at the end of the document, stating that the declaration is made under penalty of perjury.
