How do I register with the State Disbursement Unit?

You need your Social Security number, your 13 or 15-digit Participant ID number, and contact information. If you do not have a Participant ID, call 1-866-901-3212 to get one. When you are ready with this information, register at www.casdu.com and follow the below steps:

Select the “Parent Paying Support” button.
Select “Register Now”
Enter the required information, including a valid email address.
A temporary password will be emailed to you.
Log in with your temporary password and follow the instructions to update your password to something of your own choosing.
You will only need to register once.
