Listing broker learns prospective buyer owes delinquent child support. Which duty requires disclosure to seller?

Honesty is a general ethical principle but not the specific legal duty that mandates disclosure in this scenario. While honesty is important in real estate, it doesn't have the precise legal definition that would require disclosure of the buyer's child support situation.

Good faith refers to fair and honest dealing in a transaction, but it's not the specific duty that requires disclosure of material facts. Good faith is a broader concept that encompasses many behaviors but doesn't specifically address what information must be revealed.

Disclosure without 'material facts' is too broad and incomplete. Not all information must be disclosed—only material facts. This option lacks the specificity of what makes certain information legally required to be disclosed.
