When a couple who have dependent minor children separates, it may be necessary for one parent to pay the other parent child support.
The purpose of child support is to help spread the available resources in order to serve the best interests of the child. Both parents should be involved in, and should share the responsibility ... and burdens ... of paying for childcare.
Child support in California is calculated by a computer program. This is called "guideline support".
The court will plug in a number of different pieces of information into the guideline support program. While there are many factors, the main ones are the number of children, the timeshare to each parent, and the parent's incomes.
