The notary commission expires at midnight on the expiration date if not renewed.

• A. Midnight on the expiration date
• B. Noon on the expiration date
• C. End of the expiration date
• D. Immediately after expiration

Answer: (A)

The key idea is the exact time a notary’s authority ends. In Connecticut, a notary public’s commission is valid until a specific calendar boundary: midnight on the expiration date. That means you may perform notarial acts up to and including the moment the clock strikes midnight at the end of that expiration date, and you must stop immediately after that moment if you haven’t renewed. Noon is not the boundary, and “immediately after expiration” would imply you could act for a moment after the limit, which isn’t allowed. Saying it ends at the end of the day captures the same boundary, but the standard phrasing used in practice is midnight on the expiration date, which clearly marks the last moment you’re authorized.
