(a) An assessment shall not be considered as invalid because the assessment was not correctly listed or because the assessment was not in the name of the true owner or owners.
     (b) If, because of an error by an assessor, a property is assessed in the name of a person who is not the true owner, and that person pays taxes on the property, the amounts so paid shall be refunded. A claim for refund shall be initiated by filing a complaint with the board of review or board of appeals and the board shall allow the refund if the requirements of this Section are met. If the refund is ordered, the refund shall be made by the county collector in the manner provided by Section 20-175. A claim for refund under this Section must be made within 5 years after the taxes were incorrectly paid. Upon allowing a refund, the board of review or board of appeals shall list and assess the property in the name of the correct owner under Section 9-265.
