Which field indicates the duration of the notary's authority and is included on the certificate?

• A. My commission expires: ________
• B. Instrument number
• C. Signer name
• D. Notary's address

Answer: (A)

The field that shows how long the notary can act is the one that reads “My commission expires: ________.” This is the expiration date of the notary’s commission, so it marks the end of the notary’s lawful authority. Any notarizations performed after that date aren’t valid until a new commission is issued and the certificate updated. The other fields serve different purposes: the instrument number is just a document identifier, the signer name identifies who signed, and the notary’s address is contact information and not related to how long the authority lasts.
