15-17-326 . Voided tax lien -- refund -- limitation on action for royalty interest. (1) If a tax lien attached under the provisions of this chapter is declared void by a court for irregularity in the assessment, levy, or assignment or if a tax lien is assigned in error, the money paid by the assignee must be refunded, with interest at the rate payable upon delinquencies, as provided in 15-16-102 , from the date of the payment, to the assignee, together with any penalty paid by the assignee.
(2) Following the payment of a refund as provided in subsection (1), the county is the possessor of the tax lien upon the property for the legal taxes on the property accruing from the date of delinquency, plus penalties and interest as provided in 15-16-102 . Any money refunded that was received, as provided in 15-17-323 , and distributed by the treasurer to the state or a city, town, or district must be charged to the state, city, town, or district, respectively, by the treasurer and deducted from the next money due the state, city, town, or district on account of taxes paid or collected. An assignment made by a city or town that by resolution or ordinance collects its own taxes instead of having the taxes collected by the county treasurer must be reimbursed in similar manner and in similar circumstances out of the city or town treasury upon order of the mayor or, when applicable, the city manager or presiding officer of the city commission. The city or town clerk or city or town treasurer, as appropriate, shall make proper charges and deductions against the respective funds of the city or town upon the next collection of taxes by the city or town.
(3) The assignee has a lien upon the property for the amount of taxes, penalties, interest, and costs paid, with the interest to be at the rate specified for delinquencies in 15-16-102 . If the assignee is in possession of the property and resides on the property, the assignee may not be ejected from the property until the assignee's lien has been liquidated.
(4) All affirmative defenses at law or equity, including but not limited to estoppel, laches, and adverse possession, may apply in a suit brought to challenge the title to a royalty interest in land claimed to have been acquired by a county by tax deed.
(5) An action against a county to recover a royalty interest in land acquired by the county by tax deed must be brought within the period prescribed in 27-2-210 .
