Many of you will notice that on a Notary certificate such as an acknowledgment certificate or jurat certificate there is no place for the signer to sign. The certificate forms are for the notary to fill out — for the notary ONLY. The notary indicates the venue, date, who the signer(s) are, and entering the name of the notary. The notary signs and seals (stamps) but the signer should not inscribe any information on that form.

BTW, this is a beginner question. If you are advanced and don’t know this — good God!
