In some Chicago custody law matters, parents wonder whether they can waive Illinois child support in exchange for sole custody. Parents have a legal obligation to provide financial support to their children. This obligation is for the child’s benefit and not for the custodial parent’s benefit. Generally, a custodial parent cannot waive the child’s right to financial support. In a particular case, Illinois courts decide whether to order a parent to pay child support and other child-related expenses. The obligation to pay child support is independent of whether the parent has a relationship with the child. In high income cases, the judge may deviate downward from the statutory guideline amounts.
