SDCL § 36-21A-133: Disclosure of client information by seller's or landlord's agent.

Without the express written authority of the seller or landlord, no licensee acting as a seller's or landlord's agent may disclose any confidential information about the client unless disclosure is required by statute or rule or failure to disclose the information would constitute misrepresentation. No cause of action for any person may arise against a seller's agent for making any required or permitted disclosure.

A seller's agent does not terminate the seller's agency relationship by making any required or permitted disclosures.
