When any real estate is sold for taxes, it shall not be necessary to sell it as the property of any person or persons; and no sale of any real estate for taxes shall be considered invalid on account of its having been charged on the tax roll in any other name than that of the rightful owner, but such real estate must be in other respects described on the tax roll as provided by Kan. Stat. Ann. § 79-2316, and the taxes for which it is sold must be due and unpaid at the time of such sale.
