Wisconsin rules for demand letters
Small claims court in Wisconsin
The general small claims limit in Wisconsin is $10,000. The Wisconsin small claims sources we checked do not require a demand before filing, but a written demand is still useful evidence. No pre-suit demand requirement was found in the small claims statutes or the court's self-help pages.
The small claims court finder shows the filing fee for your amount, where to file and how to serve; our Wisconsin small claims guide walks through the whole case.
Security deposits in Wisconsin
The landlord must deliver or mail the full deposit, less lawful deductions, within 21 days (for a tenant who moves out when the rental agreement ends, 21 days after that date). If anything is withheld, the landlord must send, in the same period, a written statement accounting for every amount withheld. A tenant who suffers a monetary loss from a violation of these rules can recover twice the loss, plus costs and a reasonable attorney fee. Wis. Admin. Code ATCP 134.06(2)
Consumer protection notice in Wisconsin
The sources we checked show no general written-notice requirement before a consumer lawsuit under the Wisconsin Deceptive Trade Practices Act (Wis. Stat. § 100.18). No pre-suit demand letter is required. A person who suffers a monetary loss from a violation may recover that loss plus costs and reasonable attorney fees, and must sue within 3 years after the unlawful act or practice.
What a demand letter should say
A demand letter is a short, factual request for payment. It names who owes whom, how much, and why; it sets a date to pay; and it says what you will do next if you are not paid. Keep it to what you could prove to a judge: the agreement, the dates, the amount, and any payments already made.
- Your name and mailing address, the date, and the other side's name and address.
- The amount you are asking for and how you got to it.
- A short account of what was agreed and what went wrong.
- A clear deadline and how to pay.
- Your next step if you are not paid, such as filing in small claims court.
Send it in a way you can prove, such as certified mail with a return receipt, and keep a copy for the court file.
