Child support guidelines are based on what is called an Income Shares model — meaning the award is calculated from the parents’ collective gross income.
Support presumptively terminates at 18, when the child legally marries or when the child graduates from high school. The Court may NOT order the parents to pay for the child’s college education costs.
Also, child support payments must NOT stop, even if visitation is being prevented by the non-custodial parent. Unfortunately, the legal obligation to pay is separate from the duty of custodial parents to comply with the parenting plan and/or Court’s order pertaining to visitation.
If a parent is deprived of visitation, he or she MUST still provide support. Arizona will allow for modification of child support as long as a substantial change has occurred and the change is not something that has previously been addressed.
The change will typically be associated with living arrangements and income.
