The court shall, after the expiration of the time provided in section 77-1903 and on the motion of the plaintiff, examine the proceedings and, if they are found to be correct and if the subsequent taxes have been paid to date, in case the purchaser is not a land reutilization authority or a governmental subdivision of the state, a municipal corporation or an irrigation or drainage district interested in the distribution of the proceeds of the foreclosure sale, make and enter an order of confirmation of the sale, shall direct the disposition of the proceeds of the sale and order the sheriff to make and deliver to the purchasers, without further cost to them, a sheriff’s deed for any real estate not redeemed; Provided, if a private purchaser at any sale held by the sheriff in tax foreclosure proceedings shall fail to pay the subsequent taxes levied and assessed against the property under foreclosure, any governmental subdivision of the state, municipal corporation or drainage or irrigation district, interested in the distribution of the proceeds of the foreclosure sale, may apply for and have issued to it a certificate of tax sale covering such subsequent taxes in the manner provided by sections 77-1809 and 77-1810, and, upon production of such certificate in the court conducting said foreclosure proceedings, such court may thereupon order confirmation of such foreclosure sale, notwithstanding the private purchaser has failed to pay the subsequent taxes levied and assessed against the property.
