How to Stop Child Support Payments in Arizona: Filing and Arrears

To stop child support payments in Arizona, you file a petition with the superior court that issued your order, serve the other parent, and then get the signed termination order to the paying parent’s employer and to the Arizona Support Payment Clearinghouse. Payments almost never stop on their own, even when the child ages out. Until someone tells the employer and the state’s payment system to shut off withholding, the deductions keep coming.

Confirm Your Obligation Has Legally Ended

Every Arizona child support order carries a presumptive termination date, or PTD, which should appear on the face of the original order. For most families, the PTD is the last day of the month in which the youngest child covered by the order turns 18.¹ If the court determined the child would not finish high school before turning 18, the PTD moves to the expected graduation date or the child’s 19th birthday, whichever comes first.²

Support can also end before the PTD if the child becomes emancipated. Arizona treats a child as emancipated for support purposes when the child marries, reaches the age of majority, is adopted by someone other than the paying parent, or dies.³ The general support duty applies only to minor, unemancipated children.⁴

One extension worth flagging. A court can continue support past the age of majority for a child with a severe mental or physical disability if the child cannot live independently, cannot be self-supporting, and the disability began before age 18.² If your order includes a disability finding, expect it to remain in place unless a judge specifically rules otherwise.

Ending Support for Other Reasons

If you are not aging out but your situation has shifted, the court can modify or terminate support when either parent shows a substantial and continuing change in circumstances. A major income change, the paying parent taking primary custody, or a change in the child’s health insurance coverage all qualify.³ For Title IV-D cases handled by the Division of Child Support Services, either parent or DCSS can request a review every three years without showing any change at all.

Timing matters. A modification or termination takes effect on the first day of the month after the other parent receives notice of your petition, not the date you filed it. The court cannot back-date the change earlier than the filing date, and anything that accrued before the other parent was notified stays enforceable.

A separate route exists if paternity was established by fraud, duress, or a material mistake of fact. The petitioner must prove this by clear and convincing evidence, and the court will order genetic testing of the petitioner, the child, and the mother. If testing confirms the petitioner is not the biological father, the court vacates the paternity determination and terminates future support, though past arrearages usually survive.³

Gather Your Forms and Information

Arizona superior courts publish self-service packets for child support matters. Which packet you need depends on whether the other parent agrees. If both parents agree, an agreement-based packet can stop the income withholding order. If the other parent disagrees or cannot be reached, you file a petition instead. Maricopa County, for example, uses a “Petition to Stop Income Withholding Order” along with a proposed order and a Current Employer Information Sheet. Form names and numbers vary by county, so check with your local clerk or self-service center.⁵

Before you file, pull together:

The original child support case number.
A Sensitive Data Cover Sheet for Social Security numbers and other private information, so those details stay out of the public court file.
The specific legal basis for termination: the child’s age, graduation, an emancipating event, or a changed circumstance.
The paying parent’s current employer name and address, so the court can direct the employer to stop withholding.

If DCSS is involved in your case, a DCSS representative may need to sign any stipulated agreement. Confirm this with your local DCSS office before you file anything.

File the Petition and Serve the Other Parent

File the completed forms with the Clerk of the Superior Court in the county that issued your original order. Bring the originals and several copies for the court to stamp. The filing fee for a postadjudication petition in a domestic relations case is $102.⁶ No fee is charged for a stipulation concerning satisfaction of support obligations, and the fee is waived for requests to terminate an assignment when the employer is already withholding on multiple assignments for the same children. Fee waivers and deferrals are available if you cannot pay.⁷

After filing, the other parent must be formally served. Under Arizona’s Rules of Family Law Procedure, service can be completed by a sheriff, a sheriff’s deputy, a registered private process server, or a person specially appointed by the court.⁸ If the other parent is inside Arizona, certified mail with a signed return receipt also works. You cannot serve the papers yourself. If DCSS is a party to the case, the agency must also be served.

What Happens After Filing

Once served, the other parent has 20 days to file a response if served within Arizona, or 30 days if served outside the state.⁹ The same deadlines apply if the other parent voluntarily accepts service, keyed to where they signed the acceptance.

No response by the deadline lets you ask the court to enter a default order terminating support without a hearing. If the other parent contests the petition, the court schedules a hearing where both sides can present evidence. The court may award attorney fees and court costs to the prevailing parent.³

Make Sure Withholding Actually Stops

A signed order from the judge is only half the job. If child support is coming out of your paycheck, the deduction continues until the employer and the state’s payment system are told to stop. This is where parents most often lose money they no longer owe.

Send a copy of the signed termination order to the paying parent’s employer with a written request to discontinue withholding. Send another copy to the Arizona Support Payment Clearinghouse, the central state agency that receives, tracks, and distributes all child support payments.¹⁰

Notifying the Clearinghouse is not a formality. Its records are the official proof of what was paid and what was not. If the account is not closed out, the system can continue showing a growing balance that looks like unpaid arrears. Direct payments to the other parent are not credited against your obligation unless the court specifically ordered direct payment or both parties had a written agreement allowing it.¹⁰ Paying the other parent directly while withholding continues is how parents end up paying twice.

Recovering Overpayments

If withholding kept running after your obligation ended, Arizona law provides a path to seek reimbursement. A.R.S. § 25-527 allows a parent whose support obligation has ended to file a request for reimbursement of excess payments made after the termination date. Courts respond better to parents who move quickly to stop payments and then petition for a refund than to those who wait months or years to raise the issue. File your termination paperwork and notify the employer and Clearinghouse as soon as the obligation ends. Delay is the single biggest reason parents lose money.

Unpaid Arrears Do Not Go Away

Terminating current support does not erase past-due amounts. Each missed installment becomes enforceable as a final judgment when it comes due, and Arizona exempts these judgments from the normal renewal requirements, so arrearages remain collectible until paid in full.³

Enforcement continues too. State child support agencies can submit past-due balances for federal tax refund offset, with intercepted amounts routed to the state and typically disbursed within 30 days.¹¹ Once past-due support reaches $2,500, the federal government can deny, revoke, or restrict a U.S. passport, and removal from the passport denial list is not automatic once the balance drops.¹² Ending the current obligation stops future charges from accruing, but any back balance follows you until it is resolved.
