A notarial certificate is an official document issued by a notary public to provide evidence of the identity, authority, or legality of a transaction. The components of this certificate include: the official seal of the notary, the signature and printed name of the notary, the date of execution, a statement of facts which confirms the identity or authority of the signer, a jurat (an oath or affirmation sworn or affirmed by the signer before the notary), the type of requested service provided by the notary, the name of the document being attested, a legend for notarization, and any required addenda to satisfy state-specific requirements. With these components in place, a notarial certificate offers legal proof that a transaction was properly witnessed, thereby ensuring valid and reliable results.
