Both parents are responsible for the financial support of all of their children until the children reach the age of 18. If the child or children are still in school at the age of 19, and still live at home and are unable to provide their own support, it is up to the parents to provide that support.
The state of California mandates the amount of child support that is paid from one parent to the other. The amount is figured by the computer generating of the payer’s financial status. The parent’s income, the amount of taxes that they pay, the amount of time that the parent has with the child, mandatory items that are deductible such as health insurance and retirement and the custodial parent’s ability to earn and their income are the main factors that determine the amount of child support to be paid. Child support can be altered should financial changes occur with the parent paying the support, or if the time share between the two parents should change at any time.
