Final answer:
To confirm a client's Legal/Business Name, an identification card, passport, and driver's license are among the documents that can be used. These government-issued IDs include the legal name. For business verification, additional official documents may be necessary.
Step-by-step explanation:
To confirm a client's Legal/Business Name, one could check various forms of identification that include this information. Commonly accepted documents for verifying a person's legal name include their identification card, passport, and driver's license. Each of these documents is issued by governmental agencies and typically includes the full legal name, which can be used for official and legal purposes. However, it is important to note that a driver's license could indicate a residential requirement as seen in some places like California, where a commercial licensed driver must maintain a residence address, or the license will be downgraded. For business-related contexts, additional documentation such as business registration certificates, tax identification documents, or other legal documents establishing the business entity may also be required for confirmation.
