Apportionment of sale proceeds--Disposing surplus proceeds

The proceeds of the tax deed sale, after deducting the expenses incurred by the county in the proceeding to take tax deed and in the sale proceeding, must be distributed by prorating the proceeds on the basis of the tax levies for the most recent year for which taxes are included in the proceeds of the sale, until all tax and interest have been paid.
Any surplus proceeds of the tax deed sale that remain after payment of the taxes, penalty, interest, county liens and other costs, must be returned to the prior owner of record. If the prior owner of record cannot be found within one hundred eighty days, the surplus must be transferred to the Unclaimed Property Division pursuant to chapter 43-41B .
