What if the employee already has other assignments of garnishments on his or her income?
Answer in detail:
While the total amount withheld may never exceed the permissible limit, the child support withholding obligation takes priority over any other claim, secured or unsecured, on income except claims for current federal, state and local taxes. Thus, child support withholding takes precedent over creditor garnishments to the extent that the total withholding would otherwise exceed the permissible limit. If there is more than one child support withholding order against the same employee, the orders must be complied with on a pro rata basis.
Example: An employee is already subject to a child support income withholding order in the amount of $100 per week. The maximum that may be withheld from this particular employee's weekly earnings is $120 per week. A second child support income withholding notice for the same employee is received by the employer for $50 per week. The employer would withhold and submit $80 per week on the first order and would begin withholding and submitting only $40 per week on the second.
