Application for Child Support Services

Welcome! We're glad you're here.

Enrolling in child support services used to be a long, complicated process, but those days are behind us. 

The NEW California Child Support Services application was designed to allow you to provide as much, or as little information as you choose. 

Ready to Begin?*

Depending on how much information you can provide, it could take between 5 and 15 minutes to complete this application.


You will be asked to provide basic information about yourself, your child(ren), and the person you wish to open this child support case with.

  • Name/age/location/contact details
  • Information about the relationships between the adults and child(ren)
  • Details regarding custody/visitation and prior court orders (if any exist)

NO - You are not required to have or provide a SSN or ITIN to complete this application or receive services from any child support office in the state of California. 

This online application does ask for the last 4 digits of your Social Security Number (SSN) or Individual Taxpayer Identification Number (ITIN) but you can leave that question blank if:

  • you don't have an SSN or ITIN
  • you don't have that information readily available
  • you are not comfortable providing that information in an online platform
