What should be included in the change-of-name notification to the department?

The correct choice is to include a certified copy of the legal document in the change-of-name notification to the department. This ensures that the department has official and verifiable proof of the name change. Legal documents, such as marriage certificates or court orders, serve as authoritative evidence that supports the request to update the name within the department's records. This requirement helps maintain accuracy in official documents and prevents any fraudulent claims or identity mismatches.

While other choices may seem plausible, they do not meet the necessary legal standard required for such notifications. Simply providing the new name does not substantiate the change without accompanying legal proof. An explanation for the change, while informative, is not typically a requirement for the department's records. Personal identification, although important for verifying identity, does not replace the need for a certified legal document specifically stating the name change.
