Direct answer
What does First substantive contact mean?
The point at which a conversation becomes specific enough that agency disclosure may be required for the recipient and role involved.
Exam cue: Do not apply one timing rule to everyone. Section 443 sets different timing for listing agents, buyer or tenant agents and contacts with the opposite side.
What does it look like in a question?
New York example
A seller's agent begins discussing a buyer's needs and a particular residential transaction with that buyer.
Common exam trap
What should you not confuse it with?
A greeting or basic factual exchange is not automatically substantive, and first substantive contact is not every disclosure deadline.
