Whenever, from time to time, the agency has satisfied the court that the amount deposited with the court is either greater than required or is insufficient to satisfy the claims of all persons interested in the real property, the court may order that the amount of the excess be repaid to the agency or may order additional sums deposited as the court deems necessary. Whenever the agency has satisfied the court that the claims of all persons interested in the real property taken have been satisfied, the unexpended balance shall be repaid immediately to the agency.
