Frequently Asked Questions
How is child support calculated?
Most states use income-shares or percentage-of-income models considering both parents' income, number of children, and custody time. Official state calculators give exact numbers.
Can support be modified?
Yes — a significant income change or custody change can justify a modification, typically filed through your state's child support agency or court.
