what legal form do i need to give my employer for my final child support payment, while in court i was asked to go get a copy of that form or online, i don't know what form that would be?
I'm not sure what form you are talking about. Most court forms can be obtained for free from the California Court's website at: http://www.courtinfo.ca.gov/forms/
You may also want to check your local court's website, to determine whether there is a county specific form that covers your situation.
