Is a jurat a written statement made under oath?

No, a jurat is not a written statement itself; rather, it is a formal certificate or clause at the end of a document that indicates the document was sworn to or affirmed before a notary public or other authorized official. The jurat typically includes the date, the name of the person who made the statement, and the signature of the official. It verifies that the signer took an oath regarding the truthfulness of the contents of the document.
