Withholding of income under this chapter shall be made without regard to any prior or subsequent legal process under state law, including garnishments, attachments, wage assignments, or any other claims of creditors. Payment as required by the order for withholding shall be a complete defense by the payor against any claims of the obligor or the obligor's creditors as to the sum so paid. A payor who complies with an order for withholding of income that is regular on its face is not subject to civil liability to any individual or agency for any conduct which is in compliance with the order.
