Which of the following actions could result in a fine when acting as a Notary Public in California?

The action of failing to notify the State of a change of address can result in a fine for a Notary Public in California. This requirement is important because the state needs to maintain accurate records of all Notaries, including their current contact information. Such regulations ensure that Notaries can be reached if there are inquiries into their practices, or if there are any investigations or complaints.

Keeping the state informed of changes in address is essential not only for regulatory compliance but also to uphold the integrity and accountability of the Notary Public's role. Failure to do so could lead to penalties as it demonstrates a lack of adherence to the professional standards expected of Notaries in California. Notaries are also expected to keep accurate records and communicate changes that are essential to their practice.

While the other actions listed may carry their own implications for the practice of notarization, it is specifically the failure to notify the state of an address change that directly leads to penalties, thereby ensuring that Notaries maintain a connection to regulatory bodies.
