34 CFR 34.20 - Amount to be withheld under multiple garnishment orders.
(a) Unless other Federal law requires a different priority, the employer must pay us the amount calculated under § 34.19(b) before the employer complies with any later garnishment orders, except a family support withholding order.
(b) If an employer is withholding from a debtor's pay based on a garnishment order served on the employer before our order, or if a withholding order for family support is served on an employer at any time, the employer must comply with our garnishment order by withholding an amount that is the smaller of -
(1) The amount calculated under § 34.19(b); or
(2) The total amount withheld from the debtor's pay for orders we issue under paragraph (c)(1) of this section does not exceed the amounts specified in the orders, the amount specified in § 34.19(b)(2), or 15 percent of the debtor's disposable pay, whichever is smallest.
