A notarized document should be formatted to include the notarial certificate that includes a notary seal, but the exact wording varies from state to state. The notarial certificate portion is needed to completely authenticate the document.
For a notarized document to be officially recognized, it must contain the notarial certificate that includes the date of notarization, location of notarization, the type of identification provided by the affiant to the notary, statement of appearance before a notary and the notary's name and signature. The notary must also affix his official seal, which should include the words "notary public" as well as the location of the notary's commission.
Notarized documents should also be formatted to include the type of notarization being performed. This refers to the act being an affirmation, oath or acknowledgement. An affirmation is a simple statement that the notary affirms the document is authentic. An oath is a sworn statement that attests the document is authentic, and an acknowledgement is used by the notary when an individual acts within his own rights. When a photocopy needs to be notarized, the notary may use a certification that attests to the fact the copy is a true and original copy of the original document.
