23 Pa.C.S. § 7501.2: Compliance with multiple income-withholding orders.

If an obligor's employer receives multiple income-withholding orders with respect to the earnings of the same obligor, the employer satisfies the terms of the multiple orders if the employer complies with the law of the state of the obligor's principal place of employment to establish the priorities for withholding and allocating income withheld for multiple child-support obligees.
