At any time within two (2) years after the rendition of the final decree of the chancery or circuit court herein provided for, the owner of the lands may file his petition in the court rendering the decree, alleging the payment of taxes on the lands for the year for which they were sold. Upon the establishment of that fact, the court shall vacate and set aside that decree and provide that any landowner shall have the right to redeem any and all lands sold at that sale within two (2) years thereafter, which shall run from the day when the lands are offered for sale and not from the day the sale is confirmed.
