The Arizona Support Payment Clearinghouse is the payment-processing system used for child support and in some cases spousal maintenance payments in Arizona. Payments go through the Clearinghouse rather than directly between the parties creating an official record of every payment made and received.

The Clearinghouse record is the definitive accounting of payment history. Direct payments do not appear in the Clearinghouse record and can create disputes about what has actually been paid.

The Clearinghouse is accessed through the Arizona Department of Economic Security. Every child support order should include Clearinghouse routing information.
