Arizona's child support calculation follows a multi-step Income Shares Model. It begins by determining each parent's Child Support Income, which is then adjusted for factors like spousal maintenance. These adjusted incomes are combined to establish the Combined Adjusted Child Support Income. This combined figure is used with a Schedule of Basic Support Obligation to find the Basic Child Support Obligation. Further adjustments are made for medical insurance, childcare, education, and extraordinary child expenses. The resulting Combined Child Support Obligation is then allocated between parents proportionate to their Adjusted Child Support Incomes. Finally, adjustments for parenting time and a self-support reserve test are applied to determine the Presumptive Child Support Award.
A substantial change in either parent's income — voluntary or involuntary — can trigger a modification.
Changes in childcare costs or the children's health insurance premiums directly adjust the support amount.
If the custody schedule changes significantly, support can be recalculated under Arizona guidelines.
Medical conditions, disabilities, or educational needs can justify a departure from the guideline amount.
Common questions
An uncontested divorce in Arizona takes a minimum of 61 days due to the mandatory 60-day waiting period after papers are served. Most uncontested divorces are finalized within 90 to 120 days. Contested divorces can take significantly longer.
No, you are not required to have a lawyer to get divorced in Arizona. However, it is often recommended to seek legal advice, especially in cases involving complex property division or child-related issues, to ensure a fair and legal outcome.
Yes, Arizona is a no-fault divorce state. This means that either spouse can file for divorce on the grounds that the marriage is "irretrievably broken," without needing to prove fault like adultery or abandonment. (A.R.S. § 25-312)
Arizona is a community property state. All property acquired by either spouse during the marriage is considered community property and is generally divided equally (50/50) between divorcing spouses. Separate property, acquired before marriage or by gift/inheritance, is not subject to division. (A.R.S. § 25-211)
Arizona law mandates a 60-day waiting period after divorce papers are served or accepted before a divorce can be finalized. This period, often referred to as a "cooling-off" period, is intended to allow spouses time to reflect and potentially reconcile, though it is primarily a statutory requirement before the court can issue a final decree. (A.R.S. § 25-329)
