Is it all right for the notary public to just sign their name and provide a stamp imprint on the bottom of the document if there is no pre-printed notarial certificate?

No, it is not sufficient for a notary public to simply sign their name and provide a stamp imprint without a pre-printed notarial certificate. Notarial acts require a proper notarial certificate that includes specific language indicating the type of act performed, the date, and details about the signer and their identity. This ensures the legality and validity of the notarization. Without this, the notarization may be considered incomplete or invalid.
