How to sue your landlord for a security deposit in Wisconsin

A landlord may still pursue an unpaid accepted charge in a separate claim or counterclaim, so net recovery can be lower. Money already paid or retained toward that charge must be credited. The $200 rent balance retained in this sample is already excluded from the demand.

RE: Demand for return of security deposit - [Fictional Wisconsin rental address]

Dear Daniel Reed (fictional landlord):

I vacated the above rental property on August 01, 2026 and paid a security deposit of $2,000.00. Under Wis. Admin. Code § ATCP 134.06 (Wisconsin Security Deposit Law), the applicable return rule is: Deposit less lawful withholdings due within 21 days after the termination date (or the date a new tenancy begins if re-rented sooner; or, for late vacates, the date the landlord learns the tenant left).

DISPUTED DEDUCTIONS
I dispute the following deductions under Wis. Admin. Code § ATCP 134.06 for the reasons below. Please provide the records supporting each disputed charge, including the work, cost, and condition at issue. For replacement charges, explain the item's age and how you calculated the amount charged:

  • Repainting ordinary wall scuffs - $900.00
    Ordinary wear and tear - not deductible. Repainting after a tenancy is ordinary wear and tear unless the walls were damaged beyond normal use (large holes, unauthorized colors). Dated move-in and move-out photos help distinguish ordinary wear from tenant-caused damage.

I do not contest the following deductions, totaling $200.00: Unpaid rent balance ($200.00).

This demand does not cancel any accepted debt. Any separate claim or counterclaim must credit amounts already paid or retained toward that debt.

DEMAND
I demand payment of $900.00, the amount improperly withheld from my deposit.

This demand is limited to the amount improperly withheld. The applicable statutory remedy is conditional: under Wis. Stat. § 100.20(5), I may recover twice my pecuniary loss together with costs and a mandatory reasonable attorney's fee, with damages doubled on the entire deposit where no accounting was provided. I reserve the right to seek that remedy if its conditions are established in court.

Please deliver payment to the address above no later than September 22, 2026 (14 days from the date of this letter). This requested date does not shorten any statutory notice or cure period. If this remains unresolved after the applicable notice, service and waiting requirements are satisfied, I intend to file suit in small claims court. I have retained dated photographs of the property's condition, the lease, our correspondence, your itemized statement, the repair receipts you provided, and this demand letter.

Sincerely,


Maya Patel (fictional tenant)
