Which of the following information is NOT legally required on a notary's seal?

The correct answer identifies the information that is not legally required on a notary’s seal as the notary commission expiration date. In many jurisdictions, the essential components of a notary's seal include the notary's name and the phrase "Notary Public," as these elements clearly identify the individual and their official role. Additionally, the county where the notary is commissioned is often included to provide geographical context regarding their authority.

In contrast, the notary commission expiration date, while important for the notary to keep track of their commissioning status, is not typically a requirement for the seal itself. This is because the seal primarily serves as an identification tool for notarization rather than a record of the validity period of the notary's commission. Consequently, while it’s crucial for the notary to be mindful of their commission's expiration date to avoid unauthorized acts, it does not need to be displayed on the seal.
