Minn. Stat. § 513.75: LIABILITY FOR VIOLATION.

A person who records or files or enters into an agreement imposing a private transfer fee obligation in the person's favor after May 20, 2010, shall be liable for (1) any and all damages resulting from the imposition of the transfer fee obligation on the transfer of an interest in the real property, including, without limitation, the amount of any transfer fee paid by a party to the transfer, and (2) all attorney fees, expenses, and costs incurred by a party to the transfer or mortgagee of the real property to recover the transfer fee paid or in connection with an action to quiet title or register the title or a proceeding subsequent to initial registration. If an agent acts on behalf of a principal to record or file or secure a private transfer fee obligation, liability shall be assessed to the principal, but not to the agent.
