Transaction / Account / Invoice No.: [____________________]
Amount in Controversy: $[________]
I. Parties
-
Claimant. [CLAIMANT FULL LEGAL NAME] ("Claimant") is a natural person residing at [Claimant Street Address, City, WI ZIP] who is a member of "the public" within the meaning of Wis. Stat. § 100.18(1) and a consumer for purposes of the ATCP rules promulgated under Wis. Stat. § 100.20.
-
Respondent. [RESPONDENT FULL LEGAL NAME], a [corporation / LLC / sole proprietorship / partnership] with principal office at [Address] and registered agent in Wisconsin at [Name and Address] ("Respondent"). Respondent is engaged in the sale, promotion, or advertisement of [merchandise / securities / employment / services / anything offered] for sale, hire, use, or distribution in Wisconsin within the meaning of Wis. Stat. § 100.18(1).
II. Factual Background
-
On or about [__/__/____], Claimant [entered into a transaction with / purchased from / contracted with] Respondent for: [DETAILED DESCRIPTION — what was purchased/leased/contracted, price paid, location of transaction, salesperson, written documents executed].
-
Before and during the transaction, Respondent — through [name(s) of agent/employee] and through [advertising / website / packaging / oral statements / written representations] — made the following representations to Claimant and to the public: [DETAILED, DATED, AND PARTICULAR DESCRIPTION of each representation, including its medium and the audience to which it was made].
-
"Public" Element. Each representation was made "to the public" within the meaning of Wis. Stat. § 100.18(1). The Wisconsin Supreme Court has construed "the public" broadly to include even a single prospective buyer in a one-on-one sales context. State v. Automatic Merchandisers of Am., Inc., 64 Wis. 2d 659 (1974); K&S Tool & Die Corp. v. Perfection Machinery Sales, Inc., 2007 WI 70.
-
Untrue, Deceptive, or Misleading. Each representation was untrue, deceptive, or misleading when made, including:
- [Identify each false statement and the actual truth]
- [Identify each misleading implication and why a reasonable consumer would be misled]
- [Distinguish actionable misrepresentations from non-actionable puffery]
-
Materiality and Reliance. Each representation was material — i.e., likely to influence a reasonable person's decision — and was a material inducement to Claimant's transaction. K&S Tool & Die Corp. v. Perfection Mach. Sales, Inc., 2007 WI 70; Tietsworth v. Harley-Davidson, Inc., 2004 WI 32. Claimant reasonably relied on the representations and would not have [entered the transaction / paid the price] but for that reliance.
-
ATCP Rule Violation (if applicable). Respondent's conduct also violates one or more rules promulgated by DATCP under Wis. Stat. § 100.20, including:
- [Wis. Admin. Code ATCP 110 — Home Improvement Practices]
- [Wis. Admin. Code ATCP 127 — Direct Marketing]
- [Wis. Admin. Code ATCP 132 — Motor Vehicle Repair]
- [Wis. Admin. Code ATCP 134 — Residential Rental Practices]
- [Wis. Admin. Code ATCP 139 — Telemarketing]
- [Other applicable ATCP rule — list each by chapter and section]

-
Notice of ATCP Rule Violation. Respondent is on notice that its acts violate the ATCP rules identified in Paragraph 8 and exposes Respondent to double pecuniary damages and reasonable attorney fees under Wis. Stat. § 100.20(5).

Under Wis. Stat. § 100.18(11)(b)2:
- Pecuniary loss;
- Costs;
- Reasonable attorney fees.
Under Wis. Stat. § 100.20(5) (for ATCP rule violations):
- Twice the amount of pecuniary loss sustained;
- Costs;
- Reasonable attorney fees.
Equitable relief, including injunction against future violations.

About This Template
Consumer protection law gives buyers, borrowers, and renters rights against unfair, deceptive, or abusive business practices. Federal and state laws cover debt collection, credit reporting, product warranties, lemon cars, and more, and most of them have strict deadlines to preserve your rights. A well-drafted demand or complaint puts the business on notice, triggers their legal obligations, and often resolves the issue without a lawsuit.
Important Notice
This template is provided for informational purposes. It is not legal advice. We recommend having an attorney review any legal document before signing, especially for high-value or complex matters.
