What may triggers an investigation into a notary public's conduct?

A written complaint by an individual alleging a violation is a significant trigger for an investigation into a notary public's conduct. This is because a written complaint provides a formal record of the concerns raised and often includes specific details about the alleged misconduct. The documentation allows for a more structured and thorough evaluation of the claim, as it can be reviewed against the notary's actions and relevant laws or regulations.

In contrast, a verbal complaint might lack the necessary detail and formality needed to initiate an official investigation. Random audits, while part of oversight measures, generally do not stem from specific allegations against an individual notary but are part of routine checks. Lastly, public sentiment, while it may reflect general concerns about the profession, typically does not lead to targeted investigations without concrete allegations. Therefore, a written complaint is critical as it directly prompts the authorities to take action based on defined allegations.
