SDCL § 25-7A-24: Order for withholding of income served upon obligor where delinquent or support arrearage owed.

If an order for support does not contain a provision for immediate withholding of income or property and an obligor becomes delinquent in any part of the payment of support obligations pursuant to the order for support, or an arrearage exists, the department shall prepare and serve an order for withholding of income on the payor as provided by § 25-7A-30. The department shall also advise the obligor of the procedures to contest the withholding.
