Frequently Asked Questions Regarding
Child Support in Arizona
Discover what you need to know about Child Support Laws in Arizona.

Both parents’ gross incomes
Parenting Time
Each parent’s proportional share of the combined income
For an estimate tailored to your situation, you can use the Deliberately.ai child support calculator above. However, the court always has final authority over the amount ordered.
Child support in Arizona is influenced by each parent’s income, the number of children, and the amount of parenting time each parent has.
The court may also consider health insurance costs, childcare expenses, and adjustments or deviations allowed under the guidelines. When income or parenting time is disputed, the calculation can become more complex.
There is no single dollar amount that applies to everyone. The amount depends on income, parenting time, and guideline adjustments under Arizona law.
To get a reliable estimate before filing or negotiating, use the Deliberately.ai child support calculator above, keeping in mind that only a court order is legally binding.
In most cases, child support ends when the child turns 18. If the child is still attending high school or a certified equivalency program, support may continue until the child graduates or turns 19, whichever occurs first.
Orders involving disabilities or other special circumstances may follow different rules.
Not always. Even when a child reaches the termination age, child support does not necessarily stop automatically.
Parents may need to take formal steps to ensure the order is properly updated or terminated. Failure to do so can result in continued payments or unexpected arrears.
Yes. Arizona allows child support to be modified when there is a substantial and continuing change in circumstances, such as a significant income change or a change in parenting time.
Modifications generally apply going forward and are not retroactive, so acting promptly is important.
Uncontested modifications may be resolved in a few weeks to a few months. Contested cases—especially those involving self-employment income, disputed expenses, or parenting-time disagreements—can take longer. An experienced family lawyer can help assess realistic timelines.
Child support is intended to cover a child’s basic living expenses, including housing, food, clothing, and other ordinary needs. Certain additional costs, such as medical expenses or childcare, may be addressed separately depending on how the order is structured.
It can, but only if the court properly accounts for those costs under the Arizona Child Support Guidelines. Simply paying health insurance does not automatically reduce child support. Documentation and court approval are required, particularly if parents disagree about how expenses should be credited.
Arizona generally starts with gross income when calculating child support. Income may include wages, overtime, bonuses, commissions, and self-employment earnings.
If a parent is voluntarily unemployed or underemployed, the court may attribute income, which can be legally complex and may require professional review.
Unpaid child support can result in enforcement actions, including income withholding and other collection measures. These actions are intended to enforce compliance but can escalate if arrears accumulate over time.
Back child support does not go away on its own and generally remains enforceable until paid. Arrears may continue to be collected even after the child reaches adulthood. If you dispute the balance or face enforcement actions, legal advice is strongly recommended.
In certain circumstances, unpaid child support can lead to criminal charges. This depends on factors such as the amount owed, payment history, and whether the nonpayment is considered willful.
Because criminal exposure is serious and fact-specific, anyone facing this risk should consult an experienced Arizona attorney immediately.
Wage garnishment is common in Arizona child support cases. Other collection methods may also be available depending on the circumstances. Whether bank accounts or retirement funds can be accessed is highly fact-specific and should not be assumed without legal guidance.
It can. Shared or joint custody may affect how child support is calculated under Rule 32, potentially reducing or shifting the obligation depending on parenting time and income differences. Because these calculations can be complex, using the Deliberately.ai child support calculator above is a good starting point, followed by legal review if accuracy is critical.
It can. Parenting time plays a significant role in Arizona child support calculations, and increased parenting time may reduce or shift the obligation. Because these calculations can be technical, using the Deliberately.ai child support calculator above is a good starting point, followed by legal review if accuracy is critical.
Child support generally ends no later than age 19 if the child is still in high school. Support may continue for a child with a qualifying disability.
College support is not automatic in Arizona and depends on specific legal factors or agreements, which often require a lawyer’s input.
Parents cannot simply waive child support privately and expect it to override a court order. Child support is considered the right of the child, and any change must c omply with Arizona law and be approved through the proper legal process.
You will typically need proof of income, recent tax returns, existing court orders, and documentation of expenses such as health insurance and childcare. Incomplete or inaccurate financial information is a common reason for delays.
Child support cases can be initiated through the Arizona courts or through the state’s child support enforcement services, depending on the situation.
If paternity, parenting time, or income is contested, consulting an experienced Arizona family lawyer before filing can help avoid costly mistakes.
