When parents go through a divorce or legal separation in Arizona, child support orders are often a key part of the final judgment. But what happens when the cost of living goes up? Gas, groceries, rent, and child care are all more expensive than they were just a few years ago. If child support amounts stay the same over time, the paying parent may struggle to afford it—or the receiving parent may not be able to meet the child’s needs.
This is where inflation and cost of living adjustments (COLA) come into play. Arizona courts recognize that child support orders are not set in stone. As economic conditions shift, it may be necessary to modify support payments to ensure they remain fair and adequate.
In this article, we’ll break down how Arizona law treats inflation and rising living costs in child support cases, when you can ask to modify child support, and how CHM Law can help guide you through a child support modification.

Adjusting Child Support Payments for Inflation and Cost of Living in Arizona
How the Child Support Calculation Determines the Support Obligation
Arizona child support is calculated using a standard formula established under the Arizona Child Support Guidelines, which are authorized by Arizona Revised Statutes § 25-320. The child support calculation takes several financial factors into account, including:
- The income levels of both parents
- Childcare costs
- Health insurance premiums for the child
- Educational expenses
- The amount of parenting time each parent has
The goal is to determine child support in a way that reflects both parents’ financial ability, while ensuring the child’s standard of living is preserved post-divorce. The final child support order establishes a support obligation that remains in effect unless modified.
That said, the calculation is based on current financial conditions. It does not automatically adjust in the future unless a judge or an agreement includes a Cost of Living Adjustment (COLA) clause. If child support payments are not adjusted over time, the support amount may lose value.
Including Cost of Living Adjustments in a Support Agreement
A Cost of Living Adjustment, or COLA, is an increase in a support payment based on inflation or changes in the cost of living over time.
COLA provisions are common in long-term financial arrangements, such as:
- Social Security payments
- Spousal maintenance orders
- Long-term lease agreements
In the context of child support payments in Arizona, a COLA clause is a way to ensure the support agreement keeps up with inflation without the need to go back to court every year.
How COLA Clauses Affect the Amount of Child Support
- The clause typically links the adjustment to a government index, such as the Consumer Price Index (CPI).
- It may state that child support payments will increase annually on a specific date based on the percentage change in the CPI.
- COLA clauses are not automatic in Arizona. The parents or the judge may agree to include a COLA clause in the original child support order at their discretion.
If no COLA clause was included, you may still request a child support modification, but it must be done through the formal process with the court.
When Can You Request to Modify Child Support Due to Inflation?
Yes. Arizona law allows parents to request to modify child support under A.R.S. § 25-327 and § 25-503 when there is a substantial and continuing change in circumstances. Although the statute doesn’t list inflation explicitly, rising costs of living can fall under this category if they significantly affect the ability to pay or the child’s financial support needs.
Examples of economic changes that may justify a modification of child support include:
- A steady increase in the cost of basic necessities like food, housing, and transportation
- A significant rise in educational or medical costs for the child
- A change in either parent’s income, especially if income has not kept up with inflation
- Increases in childcare costs due to changes in availability or pricing
If you’re paying child support and feeling the squeeze of rising costs, or if your child’s needs have grown while support payments have stayed the same, it may be time to modify child support payments.
How to File a Petition and Modify Child Support in Arizona
In Arizona, you can request to change child support at any time, as long as there is a significant change in circumstances. There is no waiting period or requirement that a certain number of months pass between requests to modify.
To request a child support modification:
- File a Petition to Modify – This is typically filed with the court that issued the current child support order.
- Include Financial Information – You’ll need to submit pay stubs, tax returns, childcare receipts, and evidence of inflation.
- Serve the Other Parent – As with any family law case, the other parent must be notified.
- Attend a Hearing (if needed) – The court may approve the request based on paperwork or require a hearing.
You can also request a Simplified Modification if your new child support calculation differs by at least 15% from the last child support order. Whether you are the support recipient or paying parent, the court may grant the modification if support is warranted.
What Financial Information Supports a Request to Change Child Support?
To make your case stronger, it’s important to present clear evidence showing how inflation or rising costs are affecting your situation. Examples include:
- Updated income statements for both parents
- Receipts for childcare, school, or extracurricular expenses
- Proof of increased health insurance premiums
- Data from the Bureau of Labor Statistics (BLS) showing inflation trends in AZ
- A comparison of monthly budgets from the original support order and now
This documentation shows how support payments over time may have lost value due to inflation, justifying a request to modify child support.
How Rising Cost of Living Affects Child Support Orders
Example 1: Inflation Over Time
In 2015, a mother and father divorced and the father was ordered to pay $500 per month. The child support order did not include a COLA clause. By 2025, the cost of living in Arizona had risen dramatically. The mother filed to modify child support, citing the rising cost of housing, food, and childcare. The court agreed the support payment should be increased.
Example 2: Change in Childcare Costs
A father receiving child support filed to modify the support amount after daycare costs increased by $200 per month. He submitted receipts and inflation data, along with proof of his financial situation. The court granted the modification of child support.
These examples show how support modifications can help keep up with inflation and ensure children receive the financial support they need.
FAQs About Child Support Without a COLA Clause in Arizona
Does Arizona automatically adjust support payments for inflation?
No. Support agreements must include a COLA clause or parents must file a request to modify child support.
Can I change child support without a lawyer?
You can, but working with a family law attorney is often recommended to ensure the process is done correctly.
Can a parent request an increase in child support if only costs have gone up?
Yes. Due to inflation and rising expenses, the court may increase the amount of the child support even if income stays the same.
Does the other parent have to agree to modify the support order?
No. If you meet the legal standard for a change in circumstances, the court can modify support without agreement.
What if the court denies my request?
If the court finds that your financial information does not show a significant change in circumstances, your petition may be denied. An experienced child support lawyer can help you prepare a stronger case.
Important Things to Remember About Support Modifications
- Child support payments in Arizona do not automatically adjust for inflation.
- Parents must file a modification if inflation affects child support significantly.
- A cost of living adjustment clause can help avoid future disputes.
- You must show a continuing and substantial change in circumstances.
- CHM Law offers free consultations to review your support agreement and help you modify child support.

“Their communication and accessibility was outstanding”
I went through a divorce years ago and never felt confident enough to spend the money and energy in getting custody of my son, nor believe it was possible until I met with Alysa and Whittney at CHM. From beginning to end it was about an 18-month-long process, but it was well worth it and I would recommend them to anyone. I can’t thank them enough. Their communication and accessibility was outstanding. Not only did they give me my son back, but they gave him the best possible chance at life! Aly and Whittney, thank you!!!
Charlie Mic - Google Review
“I appreciate everything more than they will ever know”
Both my attorney Judie Rettelle and paralegal Whitney Stricker made a very difficult situation in my life (a divorce with 2 young children involved) a bit easier with first and foremost, their kindness to me and patience with me. I appreciate everything more than they will ever know. They were also extremely knowledgeable on all fronts and extremely prompt and detailed with their communication. I function the same way, so that really helped a lot. Thank you both again for everything. No one wants to have to go through a divorce, but if it happens, you need someone you can trust and count on – CHM and Judie/Whitney specifically – are those people.

“I Can’t express my gratitude enough and how happy I am with his representation”
Complete stud! Can’t express my gratitude enough and how happy I am with Timothy’s representation. Most say to strike when the iron is hot, but Timothy knew how to play it smoothly, held back his cards, and showed them at the right time. Timothy is your man if you want REAL representation and someone who cares about their clients. He is upfront and walks you through the whole process. It takes time to explain what you’re up against and tells you what could be the outcome both ways. He was able to get my EXTREME DUI along with many other charges dropped down to reckless driving with NO JAIL TIME!!!! Huge victory when the prosecutor wouldn’t budge! I hope to never be in trouble again but if I am Timothy is my man!

“She is very knowledgeable and is there with you through the whole process”
It was a pleasure working with Juanita Peña, she is very knowledgeable and is there with you through the whole process. Excellent customer service. I will be referring my family and friends.
Veronica Navarro - Google Review
“He know’s how to get really good results”
I had an unfortunate DUI arrest a little over 3 months ago. There were many DUI law firms I found online, and the reviews all seemed to be pretty good. What stood out to me about Timothy’s credentials though, was his sheer expertise in the field. After speaking with his firm during my initial consultation, it was clear to me they all took pride in fighting for their clients and achieved outstanding results. Everything was explained to me in great detail, in an honest and easy to understand way, and all my questions were answered thoroughly. Upon taking him on as my legal representation, he appeared for me in court so that I didn’t have to. Tim also called me periodically to keep me updated on my case. The outcome was a complete dismissal of my DUI case, along with a void of the license suspension which I did not think would ever happen. Those are amazing results… This is a very professional law firm, and Timothy knows how to get really good results. I would definitely recommend him to anyone who wants somebody that’s truly on their side and will fight for them.
