Connecticut: Does an agent have to disclose they are an agent?

[Trace LeDogge]

Greetings-

In Connecticut, if a real estate agent is selling their own property (not on MLS), do they have to notify the potential purchaser that they are a licensed real estate agent? If it not a legal requirement, is it ethically "required"?

The thought is that if two private individuals are discussing a non-agency linked, non-MLS sale and the seller is a licensed real estate agent, should that be disclosed.

Please and thank you.
