How To Modify Child Support In Arizona


When a couple with children gets a divorce, they must negotiate certain issues related to their children’s care, such as custody arrangements and child support payments. Child support plays a crucial role in ensuring that a child’s basic needs are met after a separation. However, circumstances sometimes change, and parents may find it necessary to modify an existing child support agreement.

In Arizona, parents have the legal right to modify child support payments under certain conditions. This article aims to provide a step-by-step guide on how to modify child support in Arizona, with the goal of ensuring a thorough understanding of the process.

Reasons for Modifying Child Support

Before attempting to modify a child support agreement, it is essential to understand the valid reasons recognized by Arizona law.

Significant Change in Circumstances

The primary reason for modifying child support in Arizona is when there is a significant alteration in circumstances that directly impacts the child’s financial needs. These changes may include:

  • The paying parent experiencing job loss or reduction in income
  • The receiving parent receiving a significant pay raise or promotion
  • Changes in the child’s needs, such as medical treatment requirements, starting school, or entering college

Time Interval

Another reason to seek modification of child support payments is if it has been three years or more since the existing order was issued or modified, and if the new support amount would differ by at least 15% or $75 per month.

Step-by-Step Guide to Modifying Child Support in Arizona

To ensure a successful modification of child support in Arizona, it is important to follow these step-by-step guidelines:

Step One: Gather Necessary Documents

The first step in modifying child support is to gather all necessary documentation. This includes:

  • The original or most recent child support order, along with any modifications made
  • Documentation proving any significant changes in circumstances since the original order was issued
  • Supporting documents relevant to your case, such as medical bills, school fees, or job loss notices

Step Two: Fill Out The Appropriate Forms

Proceed by completing the appropriate forms for modifying child support in Arizona. These forms include:

  • Petition to Modify Child Support: This form is used to formally request a modification of the existing child support order.
  • Income Worksheet: This form helps calculate the appropriate amount of child support based on both parents’ incomes.
  • Notice to Attend Conciliation Court Conference: This form schedules a meeting with a court-appointed conciliator to discuss the proposed child support modification.

Step Three: File the Forms with the Court Clerk

Once the forms are completed, they must be filed with the court clerk in the county where either you or the other parent resides. The court clerk will then set a hearing date and provide you with a copy of the filed forms for your records.

Step Four: Serve the Other Parent

It is crucial to serve the other parent with a copy of the Petition to Modify Child Support and the Notice to Attend Conciliation Court Conference. This can be done in two ways:

  • Personal Service: Either you or an authorized representative can physically deliver the documents to the other parent.
  • Certified Mail: The documents can be sent to the other parent via certified mail. Retain a copy of the mailing receipt for your records.

Step Five: Attend the Conciliation Court Conference

After the other parent receives the documents, both parents must attend the conciliation court conference. This conference provides an opportunity to discuss the reasons behind the proposed child support modification and work towards reaching an agreement. If an agreement is reached, it can be submitted to the court for approval.

Step Six: Attend the Child Support Modification Hearing

If both parents are unable to reach an agreement at the conciliation court conference, a hearing will be necessary. It is strongly recommended that you seek representation from an experienced Arizona family law attorney for any hearings. During the hearing, the judge will hear arguments from both parties before making a decision on whether to grant the modification.


Modifying child support in Arizona may involve an intricate process, but it is essential to ensure that your child receives adequate support. By following the steps outlined above and enlisting the help of an Arizona family law attorney, you can navigate the necessary procedures for modifying your child support agreement easily and effectively.
