In which county should John Notary complete the notarial certificate when notarizing for Mary White?

The correct answer is based on the requirement that notaries must complete the notarial certificate in the jurisdiction where they are performing the notarization. In this scenario, if John Notary is located or appointed in Cook County, he is legally obligated to indicate that jurisdiction on the notarial certificate. This practice helps to maintain proper records and ensures that the notarial act complies with local laws and regulations.

When notarizing documents, it is essential for notaries to accurately reflect the details of their location at the time of the notarization. This not only establishes authenticity but also ensures that the notarization has been conducted in accordance with state laws. Hence, if the notarization is to take place in Cook County, that is where the certificate should be completed.
