South Dakota requires agency disclosure:

Disclosure at closing is far too late to be meaningful — by that point, the buyer and seller have already negotiated, signed contracts, completed inspections, and made major financial commitments. Any confidential information shared during the transaction process would have already been potentially compromised. Closing-time disclosure would render the entire purpose of agency disclosure meaningless.

Agency disclosure is not optional or conditional upon a consumer's request in South Dakota. Requiring consumers to ask for disclosure before receiving it defeats the protective purpose of the law, as most consumers don't know to ask and may not understand what agency relationships are. The disclosure obligation rests entirely on the licensee, not the consumer.

South Dakota absolutely requires agency disclosure — answering 'never' is factually and legally incorrect. All U.S. states have implemented some form of agency disclosure requirement, and South Dakota is no exception. Selecting 'never' would indicate a fundamental misunderstanding of consumer protection principles in real estate.
