South Dakota Agency Relationships

South Dakota law defines the types of agency relationships that real estate licensees may have with consumers.

Types of Agency Relationships

Single Agency

A single agent is a licensee who represents only one party in a transaction:

Single Agent RoleRepresents
Seller's agentSeller only
Buyer's agentBuyer only

Single agent duties include:

  • Undivided loyalty to the client
  • Confidentiality of client information
  • Full disclosure of material facts to client
  • Obedience to lawful instructions
  • Accounting for all funds
  • Reasonable care and diligence

Limited Agency (Dual Agency)

Limited agency occurs when the responsible broker represents both parties in a transaction:

  1. Two agents in the same brokerage represent the buyer and seller, OR
  2. One agent works for both the buyer and seller

Requirements for Limited Agency

RequirementDescription
Written consentBoth parties must consent in writing before the relationship
Prior disclosureFull disclosure of the limited agency relationship
Confidentiality limitsCannot disclose price/terms one party will accept
Neutral positionMust remain impartial to both parties

Key Point: Limited agency may only occur with prior written permission of both parties. In a limited agency relationship, the broker may not be able to provide full advocacy to either party.

Appointed Agents (Designated Agency)

Appointed agents allow the responsible broker to designate separate licensees to represent each party:

FeatureDescription
PurposePreserve advocacy for each party in same-brokerage transaction
DesignationResponsible broker appoints specific agents
ConsentRequires knowledge and written consent of both parties
ConfidentialityEach appointed agent maintains client confidentiality

Duties to ALL Parties

South Dakota law imposes certain duties on all licensees to all parties in a real estate transaction, regardless of representation:

Universal Duties

DutyDescription
Material fact disclosureDisclose all known material facts about the property that could affect use or enjoyment
Transaction abilityDisclose information that could impact either party's ability to fulfill obligations
Honest responsesRespond honestly and accurately to questions from any party

What Must Be Disclosed to All Parties

Regardless of who the licensee represents:

  • Known material facts about the property
  • Information affecting transaction ability of either party
  • Honest and accurate responses to all questions

Transition to Limited Agency

All licensees of a brokerage firm owe duties as described in single agency until a purchaser inquires about a property under contract for sale/lease with that same firm. At this point:

  1. A limited agency relationship may exist
  2. Limited agency requires prior written permission of both parties
  3. If no written permission is obtained, the broker cannot proceed with dual representation

Compensation Disclosure

A licensee shall not accept compensation from more than one party without full written disclosure to all parties.

SituationRequirement
Fee from one partyStandard - no special disclosure
Fee from multiple partiesMust disclose to ALL parties in writing
