(1) In a case in which only arrears are owed, if the obligor pays the total amount of child support in arrears within 15 days after service of the notice specified in 40-5-305, an order for deduction may not issue. This discharge of delinquency does not affect or otherwise limit any action as a result of any subsequent delinquencies.
(2) If there is a current support obligation, payment of arrears after service of the notice required under 40-5-305 or after service of the income-deduction order on the payor does not prevent the issuance or continuance of an income-deduction order for the payment of current support.
