Child Support
A.R.S. 25-320 — by the guidelines, back to separation for up to three years, and in high school until nineteen years of age
In a dissolution, legal separation, maintenance or support proceeding, the court may order either or both parents to pay an amount reasonable and necessary for the child's support, without regard to marital misconduct, and applies the child support guidelines back to the date of filing.
Back to the separation, up to three years. If the parents lived apart before filing and no order was in place, the court may order support back to the date of separation, but not more than three years before the filing, after considering the circumstances, including any efforts to frustrate service.
Support continues for a child who reaches majority while attending high school or an equivalency program, while attending, until nineteen years of age. A parent is presumed capable of full-time work at least at the applicable minimum wage, unless evidence shows otherwise.
