Wisconsin Agency Law Guide

Wisconsin's agency law is governed by Wis. Stat. Chapter 452 and DSPS administrative rules. Wisconsin has several unique features — most notably its emphasis on designated agency and the written buyer agency requirement — that are heavily tested on the state exam.

Agency Types in Wisconsin

Seller's Agency The listing broker represents the seller. The seller's agent owes full fiduciary duties to the seller: loyalty, confidentiality, disclosure, obedience, reasonable care, and accounting. Unrepresented buyers dealing with a seller's agent are customers who receive limited duties: honest dealing and disclosure of material facts about the property.

Buyer's Agency The buyer's broker represents the buyer. In Wisconsin, buyer agency agreements must be in writing to be enforceable — this is a state-specific rule that differs from many other states. The written agreement (WB-36 Buyer Agency/Tenant Representation Agreement) specifies the scope of representation, compensation, and term.

Dual Agency A single licensee represents both buyer and seller in the same transaction. Wisconsin permits dual agency only with the written informed consent of both parties. In dual agency, the licensee cannot disclose the seller's minimum acceptable price to the buyer or the buyer's maximum willing price to the seller. The loyalty duty is suspended — the agent is neutral.

Designated Agency (Wisconsin's Preferred Model) This is Wisconsin's distinctive contribution to agency law. Instead of dual agency, a firm may designate one licensee to represent the seller and a different licensee to represent the buyer. Both designated agents can provide full representation to their respective clients without the conflict inherent in dual agency. Designated agency is the norm for in-house transactions at larger Wisconsin firms.

Disclosure Requirements

Wisconsin requires agency disclosure at the first meeting where substantive real estate services are provided. The disclosure must be written and must explain the agency relationship being offered.

For in-house transactions where buyer and seller are both represented by the same firm, the broker must disclose this situation and obtain consent for either dual agency or designated agency.

Customer Duties

When a Wisconsin licensee works with a customer (a party not represented by the licensee), the licensee owes: - Provide information about the property - Present all written offers and counteroffers promptly - Account for all funds received - Disclose material adverse facts about the property that are not readily observable

The licensee does NOT owe customers loyalty, confidentiality, or advice about negotiating strategy.

WB-36: Buyer Agency Agreement

The WB-36 is the Wisconsin standardized buyer agency agreement. It specifies: - The property types and geographic area covered - The term of the agreement - Compensation (how the buyer's agent is paid) - Dual agency consent provisions

The written requirement for buyer agency means a licensee cannot be compensated for buyer representation without a signed WB-36 or equivalent written agreement.

Exam Focus

Designated agency (vs. dual agency), the written buyer agency requirement (WB-36), and the customer vs. client duty framework are the three most tested agency topics in the Wisconsin state section. Know them cold.
