What must a notary do within thirty days of changing their address?

When a notary changes their address, they are required to send a signed notice of this change to the Attorney General within thirty days. This requirement ensures that the notary's records are kept current and that all legal documents can be accurately processed without delays or issues related to outdated information. A notary's address is crucial for maintaining communication and verifying their credentials, making it essential for them to notify the appropriate authority in a timely manner.

The other options do not align with the formal requirements for notary practice. For instance, while notifying local authorities may be necessary in other contexts, it does not pertain to the responsibilities of a notary in this case. Similarly, filing a report with the Secretary of State might seem plausible, but it is not the correct protocol for address changes. Updating a social media profile, while a good personal practice, has no bearing on the official responsibilities of a notary.
