A self-declaration form is a formal statement signed by an individual that certifies that the information provided is correct. In other words, it is a legal document that verifies that all of a person's information is truthful and correct. A self-declaration form, unlike an affidavit, does not require witnesses or notarization. A self-declaration form can be viewed as a two-factor verification that double-checks information that has already been provided. Self-declaration is a distinct form that refers to the principal document containing the information in particular scenarios.
