Is there a conflict of interest here?

[Mitch Kronowit]

This isn't quite a hypothetical question, but I'll keep it general in nature.

I've noticed a few husband/wife teams (or couples in alternative relationships) where both are real estate professionals. If one were the listing agent of a certain property and the other were acting as the buyers agent for the same, could this be construed as a conflict of interest as both of them share a household together? Would you trust the buyers agent with confidential buyer information you wouldn't want shared with their partner?

Thanks for the advice, BP team!
