License holders have the general duty to disclose agency relationships to all parties involved in a transaction. There are actually two requirements to disclosing agency:
a) Tell everyone (agents, customers, and prospects) whom you represent (if any) at first contact. This disclosure is required at open houses. This disclosure can be oral or in writing.
b) Give the written statutory statement (IABS Notice) at the first substantive communication about a specific property.
c) Provide the IABS Notice only if requested by the client.
d) Only disclose agency relationships if requested by the client.
