A notary public is a public officer who performs official duties like witnessing signatures and administering oaths. Those duties require legal adulthood and the capacity to take on official responsibilities, which Arizona grants at age 18 (the age of majority). So, the minimum age to become a notary is 18. Remember, there are additional requirements beyond age, such as residency or employment in Arizona and meeting character and background standards, but age must be at least 18 to qualify.

In Arizona, the notary’s certificate must clearly attach to the document and show the essentials of the notarization: when and where it happened, what act was performed, who appeared, and that the notary's official authority was used. The date and the county specify the timing and jurisdiction of the act. The wording indicating the act makes it explicit whether it was an acknowledgment, jurat, or other notarization. The notary’s seal authenticates the act, and the signer’s identity confirms who appeared before the notary and proved their identity (either by present identification or personal knowledge). These elements together ensure the notarization is valid and traceable. The full text of the document isn’t required to be part of the certificate, and a photo of the signer isn’t part of the certificate.

The main function of a notary’s journal is to create a contemporaneous record of every notarial act. This log captures essential details such as the date and type of act, a description of the document, the signer’s identity, and the identification shown. Keeping this kind of chronological, verifiable record provides a reliable trail that can be used later to confirm what happened, who appeared, and what safeguards were applied during the notarization. It supports accountability and helps resolve questions or challenges about past acts. This journal is not meant to store full copies of documents, replace the notary certificate, or serve as a marketing address book. The actual documents may be kept by the parties involved, the certificate remains the formal attestation attached to the document, and the journal is a confidential, evidentiary log of the acts performed.

Arizona notary commissions are issued for a four-year term. That means once your commission is issued, it remains in effect for four years, and you must renew before it expires to continue performing notarial acts. Renewal is a straightforward process that typically involves submitting a renewal application, paying the renewal fee, and ensuring your bond and records remain in good standing. The other durations don’t match the established eight—sorry, four—year term, so four years is the correct length.
