Minn. Stat. § 332.73
Subd. 1. Notification.
(a) Before taking an affirmative action under section 332.74, a debtor must, by certified mail, notify a creditor that the debt or a portion of a debt on which the creditor demands payment is coerced debt and request that the creditor cease all collection activity on the coerced debt. The notification and request must be in writing and include documentation. If not already included in documentation, the notification must include a signed statement that includes:
Subd. 2. Sale or assignment of coerced debt.
A creditor may sell or assign a debt for which the creditor has been notified is coerced debt to another party if the creditor selling or assigning the debt includes notification to the buyer or assignee that the debtor has asserted the debt is coerced debt.
Subd. 3. No inference upon cessation of collection activity.
The fact that a creditor ceases collection activity under this section or section 332.74 does not create an inference or presumption regarding the validity or invalidity of a debt for which a debtor is liable or not liable. The exercise or nonexercise of rights under this section is not a waiver of any other debtor or creditor rights or defenses.
