(a) In all cases where notice has been properly given as set out in § 14-123-413 and where no answer has been filed, or, if filed and the cause decided for the plaintiff, the court by its decree shall:
(1) Grant the relief as prayed in the complaint;
(2) Direct the commissioner to sell the land described in the decree at the courthouse door of the county wherein the decree is entered, at public outcry, to the highest bidder for cash in hand, after having first advertised the sale weekly for two (2) weeks, consecutively, in some newspaper published in the county, if there is one. If no newspaper is published in the county, then the advertisement shall be published in some newspaper of an adjoining county. The advertisement may include all the lands described in the decree.
(b) If all of the lands be not sold on the day as advertised, the sale shall be continued from day to day until completed.
(c) The commissioner shall by proper deeds convey to the purchasers the lands so sold, and the titles to the lands shall thereupon become vested in the purchasers as against all others whomsoever, saving to infants and insane persons having no guardians or curators, but who now have the rights by law to appear and except to the proceedings within twelve (12) months after their disabilities are removed.
(d) In any case where lands are offered for sale by the commissioner as provided by this act, and the sum of the assessment due, together with interests, costs, and penalty, is not bid for the lands, the commissioner shall bid the lands off in the name of the plaintiff levee district, bidding therefor the whole amount due as aforesaid, and shall execute his deed therefor, as in all other cases under this act, conveying the lands to the plaintiff levee district. The deed, when duly executed in conformity with the provisions of this act and recorded shall be received as evidence in all cases showing an indefeasible title in the purchasers, unassailable either in law or equity.
