A properly executed notarial certificate must include which of the following?

• A. The signer's address
• B. The notary's commission expiration date
• C. The witness signature
• D. The notary's email

Answer: (B)

The key point is proving the notary’s authority at the time of notarization. A properly executed notarial certificate must show the notary’s commission expiration date to confirm the notary was legally commissioned and authorized to act when certifying the document. The signer’s address, a witness signature, and the notary’s email are not required elements of a standard notarial certificate. In short, the expiration date on the certificate demonstrates the notary’s valid authority, making it the essential item.
