New York requires disclosure of agency relationship:

Closing is too late for agency disclosure. By this point, the consumer may have already provided confidential information or made decisions based on misunderstanding their relationship with the agent, potentially leading to legal issues and invalidating the transaction.

Agency disclosure cannot be optional or based solely on client request. NY law mandates disclosure regardless of whether the consumer asks about agency relationships, ensuring informed consent and protecting consumers who may not understand real estate agency concepts.

Within 10 days of showing property is too late for initial disclosure. NY requires disclosure at first substantive contact, which typically occurs before any property viewings, allowing consumers to understand their agency relationship before making significant decisions.
