On one hand, child support seems simple. Both parents have to support the child, so the court order just evens things out, ordering the parent without custody to help by paying the parent with custody. That money isn't income for the second parent, per se, but helps buy food, buy clothing, and pay for the other many expenses of raising a child.
Child support is a critical issue in any divorce. Whether you expect to pay child support or hope to receive it, child support will have a major financial impact on your life and the lives of your children. In Illinois, courts consider the respective incomes, assets and financial circumstances of each parent to determine a monthly child support payment. However, financial circumstances change.
