What type of identification is required from a client when a mandatary is involved?

The requirement for a type of identification, document number, and issuing jurisdiction is essential when a mandatary is involved because it ensures that the person acting on behalf of a client is properly identified and has the legal authority to do so. This comprehensive identification process helps to prevent fraud, ensures compliance with regulatory standards, and establishes a clear link between the client and their representational agent.

This type of identification serves to authenticate the identity of the mandatary as well as verify the legitimacy of the documents they provide, which is critical in real estate transactions. Proper documentation that includes identifying details such as the type of ID, its number, and where it was issued minimizes risks and protects all parties involved in the transaction.

In contrast, merely requesting a phone number and email address does not provide sufficient verification of identity. A photograph alone could be misleading without accompanying identification details. Additionally, relying on social media profile information is unreliable and does not meet the legal requirements for identity verification in real estate or transactional contexts. Thus, option C stands out as the most robust and legally sound choice.
