Child Support in Arizona

Where to start

Your best first step depends on whether you already have a child support order. If you are unsure, gather any court papers, payment records, and letters from DCSS before you call.

For plain background before you call, see ASMOM’s

child support basics

. Arizona DCSS handles support services; custody, parenting time, and most divorce questions need the court or a lawyer.

How Arizona calculates child support

Arizona uses an

income shares model

. The court looks at the incomes of both parents to estimate each parent’s share of a child’s support. The

2022 Arizona Child Support Guidelines

, revised in September 2022, remain listed as current by the Arizona courts. The court calculator is for planning, not a promise of what a judge will order.

Arizona law says parents must support their natural and adopted minor, unemancipated children. If a child turns 18 while still attending high school or a certified high school equivalency program, support can continue while the child attends, but no later than age 19 under that rule. A court can also make certain orders for an adult child with a qualifying disability that began before adulthood. See the state

support duties law

and

adult disability exception

. Do not assume an order ends or changes without checking its terms.

The court may account for child care costs, health insurance, medical support, parenting time, other children, and other factors in the guidelines. The amount may also depend on the date of the case and the guideline worksheet used. If you are comparing states, the ASMOM

child support law comparison

explains why a high estimate in another state does not mean you can choose that state for your case.

How to apply for child support services

You can ask Arizona DCSS for help with a child support case. DCSS can help parents and caretakers find the other parent, establish legal parentage, seek a support and medical support order, collect and enforce payments, and request a review. DCSS may also handle spousal support when it is part of a court order it enforces.

DCSS lawyers represent the state, not either parent personally.

For advice about your own rights, ask a family-law lawyer or legal aid.

DCSS explains that a new order can be sought for a child under 18 when the legal conditions are met. Parents may be separated or divorced without a support order, may never have married, or the child may live with a relative, guardian, or other caretaker. Legal parentage must be established when required, and both parents must receive proper notice. If a parent does not respond after valid service, the court may enter a default order. Support orders also address health coverage or cash medical support.

You can apply online through the

AZCARES portal

, or use a signed paper application sent by mail, email, or secure office drop box as Arizona DCSS directs. If applying for more than two children with the same father, DCSS says a supplemental page is needed for each additional child. An unsigned form can delay a case. If you have a privacy concern, ask for a safe contact method

before

sending personal details.

You may also file through your county Superior Court. The Arizona Judicial Branch has a

resources page

with child support information, and

Find My Court

can help you locate the right court.

Application fees and what happens next

Applying for Arizona DCSS services is free.

Fees may apply after a case opens. The state

DCSS customer guide

lists an annual $35 collection fee for a qualifying case after $550 in support has been collected during the federal fiscal year (October 1–September 30), where the receiving parent has never received the public help covered by the fee rule. It also lists an $8 monthly handling fee for the paying parent on an Arizona order, and possible genetic-testing costs. Ask DCSS which fees apply to

your

case; do not assume every family pays them.

When DCSS has a complete application, it starts a case and sends the parties information about next steps. The state guide says a case should be opened within 20 calendar days after a complete application or referral. That is

not

a promise of an order or payment in 20 days. The time needed to find a parent, confirm parentage, give notice, and get an order is separate. A case can take longer if an address is unknown or someone contests the facts. Save your application confirmation and every letter you receive.

Some families receiving TANF, Medicaid/AHCCCS, or federally assisted foster-care services may be referred to DCSS rather than applying on their own. If you receive cash assistance, ask how collected child support may be handled and whether a good-cause exception may apply if there is a safety risk.

Payments, direct deposit, and the portal

After an order exists, DCSS can help with payment records and distribution. Arizona says a parent receiving support may use direct deposit or an Electronic Payment Card. A payment does not appear simply because it was ordered; funds must first be received, processed, and sent under the case rules. Ask DCSS about any payment delay or balance.

Parents who pay support can use DCSS

payment options

, including online, phone, mail, mobile, and in-person options. Some methods may have fees. Keep receipts and confirmation numbers.

DCSS also has

online services

for questions, document submission, and case updates. If you move, change phone numbers, or change email, update your information right away so notices do not go to the wrong place.

What to do when payments stop

Do not wait months before asking for help. Check your payment history and notices, then contact DCSS or the court that issued your order. Ask whether wage withholding is active, an employer changed, or an enforcement review is needed. Arizona may use tools such as income withholding, tax refund collection, liens, or license actions when the law allows. These steps do not guarantee payment when money cannot be found.

USAGov explains that state or tribal child support agencies can help get, change, or enforce an order, even if the other parent lives somewhere else, but the government does not pay child support for the parent. Read the federal overview at

Changing a child support order

Either parent may ask for a modification review when there has been a significant and continuing change. DCSS examples include income changes, job loss, disability, adding or changing health insurance, incarceration of the paying parent, or a change in custody or parenting time.

The

DCSS modification FAQ

says a review may be appropriate when the new support figure would differ by at least

15% or $50 per month, whichever is less

. This is agency screening guidance, not automatic approval. The office says review and modification should generally be completed within six months, but the court schedule and missing information can affect the time. You may also ask your local Superior Court about filing on your own.

Important:

A review may raise, lower, or leave support unchanged. Under

Arizona law, A.R.S. § 25-503(E)

, a modification usually takes effect on the first day of the month after notice of the petition. For good cause, a court may choose a different effective date, but not earlier than the filing date. Amounts already owed from before the legally allowed period generally remain due. Do not stop paying or expect old debt to disappear while you wait. Ask legal aid about arrears (past-due support), old support, service, and filing dates. In Title IV-D cases, the law also allows a review request every three years without the usual showing of changed circumstances.

For free or reduced-fee legal screening, use

AZLawHelp

. If you can afford a consultation, a family law attorney can review your order, payment history, and risks before you file.

Documents and information checklist

Gather what you have before applying or asking for a change. Do not delay forever because you are missing one document, but send as much correct information as you can.

Keep a copy or screenshot of anything you submit, plus the date, delivery receipt, agency reply, and your case number. Tell the office which paper is missing and ask how to provide it later. Never send Social Security numbers or other private data through an unconfirmed email or website.

If DCSS delays, denies, or closes your request

Ask DCSS for the reason in writing, the form or record it needs, and the time limit to respond. If it is about a court order, use the court shown on the notice. If you disagree with an agency decision, ask which review or complaint process applies; an agency review is not always the same as a court appeal. Do not guess the deadline. Save the notice and contact the

Arizona legal-aid finder

if you need help with your rights or a hearing.

If the paying parent lives in another state, on tribal land, or outside the country, tell the office. State and tribal agencies may need to work together. The

federal child support office

explains where to start, but it does not pay a parent’s support debt.
