Wisconsin: buyer-agreement requirements.

This page lists what Wisconsin requires, at the state level, before a licensee represents a buyer: who regulates real-estate licensees, whether a written buyer agreement is required by state law or rule, the statute or rule that says so, and whether the state mandates an agency-disclosure form or publishes an approved agreement form.

It is built for broker-owners and transaction coordinators who need the state rule in one place before setting office policy. Read it alongside your brokerage's own forms and your broker of record's guidance — the written-agreement question became a national practice issue in 2024, but the rule that binds you is your state's, and it is the state rule this page cites.

Wisconsin, field by field.

Regulating authority

Wisconsin Real Estate Examining Board — Dept. of Safety and Professional Services (DSPS)

Written agreement required by state law

Not verified

Statute or rule

Wis. Stat. § 452.135 (written disclosure to a party who is not the firm's client), read at docs.legis.wisconsin.gov. Board-approved form WB-36 Buyer Agency Agreement, marked 'Approved by the Wisconsin Real Estate Examining Board,' optional use date 2024-07-01, MANDATORY use date 2024-08-15 (dsps.wi.gov/Documents/BoardCouncils/REB/Forms/WB-36.pdf, form read 2026-08-15). THIS CITE COVERS THE DISCLOSURE DUTY AND THE APPROVED FORM — IT DOES NOT ANSWER THE WRITTEN-AGREEMENT QUESTION.

Agency disclosure form

Yes — the wording is statutory. § 452.135: no firm and no licensee associated with a firm may negotiate on behalf of a party who is not the firm's client unless the firm provides that party a copy of the written disclosure statement whose exact text the statute sets out. For residential property of 1–4 units, if the disclosure is not incorporated into the agency agreement, the firm must request the client's signed acknowledgment that the client received it.

State-approved form available

Yes — mandatory use

Notes. Wisconsin's answer is a FORM answer rather than a duty answer. The Real Estate Examining Board approves the WB-series forms, and WB-36 (Buyer Agency Agreement) carries a mandatory use date of 2024-08-15 — so if you use a buyer agency agreement in Wisconsin, it is WB-36 unless an exception applies. Whether you must have one at all is a different question and we did not verify it. WB forms are dated and superseded; check the date line at the top of the form before you send it.
