(a) This subsection applies to money the status of which is undetermined or that is awaiting the time when it can be taken into the treasury. The money shall be placed with the comptroller and credited to the suspense account. The comptroller shall maintain information about the deposit of funds into the suspense account in accordance with § 403.052.
(b) When the status of money placed in the suspense account is determined, the money shall be transferred from the suspense account by placing the portion of it belonging to the state in the appropriate fund in the treasury, and the part not belonging to the state shall be refunded. The refund shall be made either to the payor of the money or to the payor’s estate, assignee, devisee, or other successor-in-interest.

(c) When a deposit is made, it and any refunds shall be entered in the suspense cash book, and the balance shall represent the aggregate of the items still in suspense. Warrants shall be used for making refunds. The warrants shall be charged against the suspense funds to which they apply.
