A child support order is a court order. When the other parent stops paying — or never paid consistently to begin with — Arizona law provides different tools to compel compliance and recover what's owed. But enforcement doesn't happen automatically, and how you approach it matters as much as whether you act at all.
Two tracks for enforcement in Arizona
Child support enforcement in Arizona runs on two parallel tracks. The Division of Child Support Services (DCSS) is a state agency that pursues enforcement administratively and through the courts on behalf of parents to whom child support is owed. It handles a large volume of cases and operates at a pace that reflects that volume. For parents dealing with significant arrears or a parent who is actively evading obligations, private legal representation through your own family law attorney tends to produce faster results.
The two approaches aren't mutually exclusive and some parents engage both simultaneously; but understanding the difference helps you set realistic expectations about timelines and outcomes.
Income withholding orders
The easiest and most reliable enforcement mechanism is an income withholding order (IWO). Sometimes also called wage assignment, the IWO requires the employer of the parent who owes child support to deduct support payments directly from each paycheck and send them to the Clearinghouse which then forwards the funds to the parent to whom support is owed. In most cases, an IWO is built into the original support order. When the paying parent changes jobs, a new IWO must be issued to the new employer. If you don't know where they work, a family lawyer can help you obtain this infomration.
Contempt of court
Willful failure to comply with a child support order exposes the noncompliant parent to contempt proceedings. You file a petition for an order to show cause, asking the court to require the other parent to explain their noncompliance. A contempt finding can lead to fines, additional court-imposed payment plans, and in cases of significant and deliberate nonpayment, incarceration.
The operative word is willful. A parent who genuinely cannot pay due to job loss or a serious medical situation may have a valid defense, espeically when compared to a parent who is working under the table, hiding income, or simply choosing not to comply. Courts recognize the distinction, and it meaningfully affects how contempt proceedings unfold.
License suspension
Arizona law authorizes suspension of a noncompliant parent's driver's license, professional licenses, and recreational licenses when arrears reach a certain threshold. For parents in licensed occupations or those who depend on driving for work, this is often one of the most motivating enforcement tools available. DCSS administers the process, and in many situations it can proceed without a court hearing. If the other parent holds professional licenses and owes substantial arrears, this option is worth a specific conversation with your attorney.
Passport denial and tax refund intercept
Federal enforcement mechanisms add further leverage. Parents who owe more than $2,500 in arrears can be reported to the U.S. Department of State, resulting in passport denial or revocation. Federal and state tax refunds can be intercepted through the tax refund offset program and redirected toward unpaid support. These operate largely through administrative channels and don't require you to initiate separate court proceedings, though they work best as part of a broader enforcement strategy rather than in isolation.
Collecting arrears
Unpaid child support doesn't disappear. Arizona arrears accrue interest at a statutory rate, and the obligation survives the child's eighteenth birthday. This means that a parent who falls behind can be pursued for collection well after the child is no longer a minor. That said, collecting from a parent who is self-employed, paid in cash, or has relocated out of state requires navigating additional procedural layers. Interstate enforcement operates under the Uniform Interstate Family Support Act (UIFSA), which provides mechanisms for enforcing Arizona orders across state lines, but those procedures require experience to navigate effectively.
Getting enforcement right
The enforcement tools exist, but deploying them strategically, i.e. choosing the right mechanism, filing correctly, and moving quickly when a parent is evading obligations makes a real difference in results. Filing errors or delay can give a noncompliant parent room to maneuver in ways that are difficult to recover from.
If you are owed child support in Arizona and the other parent isn't paying, Novo Law offers free consultations to help you understand your options and build an enforcement strategy that fits your situation. In most cases where a parent is held in contempt for non-payment of child support, the other parent can seek reimbursement of their attorney's fees and costs as part of the proceeding. This is intended to enable parents seeking to enforce child support to have the option to retain experienced counsel to help them through the processes without additional financial harm.
