Post-Decree Modifications FAQ

Arizona requires you to demonstrate a "substantial and continuing change in circumstances" since the original order was entered. The change must be significant and not temporary — minor or short-term shifts generally won't qualify. This standard applies to child support, parenting time, legal decision-making, and spousal maintenance modifications.

Common examples include a significant job loss or income change, a parent relocating, a child's evolving needs, or a material change in either party's health. Courts evaluate whether the change is ongoing rather than temporary. The burden of proof falls on the party requesting the modification.

For child support and spousal maintenance, you can petition as soon as a qualifying change in circumstances occurs. For legal decision-making (custody), Arizona generally requires you to wait one year after the prior order unless the child is in danger. There is no mandatory waiting period for parenting time modifications.

Generally, no. Under Arizona community property law, once a court divides marital assets and debts in the decree, that division is final and cannot be modified. Exceptions exist for fraud, mistake, or failure to disclose assets. Only ongoing obligations like support and parenting arrangements are modifiable.

No, but mutual agreement makes the process significantly faster and less expensive. If both parties agree, you can submit a stipulated modification to the Superior Court for approval. If you disagree, a judge will hold a hearing and decide based on the best interests of the child or other applicable legal standards.

Yes — a significant, involuntary job loss is one of the most common grounds for modifying child support in Arizona. You must show the income change is substantial and continuing, not temporary. File a Petition to Modify Child Support with the Superior Court in your county as soon as possible, since modifications are rarely backdated.

Arizona uses the Income Shares Model, which considers both parents' gross incomes, parenting time, childcare costs, and health insurance premiums. A modification resets the calculation using current figures. The Arizona Child Support Guidelines worksheet is required to be submitted with any modification petition.

You must file a Petition to Modify Parenting Time or Legal Decision-Making in the Superior Court where the original order was entered. The court's primary consideration is always the best interests of the child. For legal decision-making changes, you must typically wait one year after the last order unless there is a safety concern.

Arizona law requires a parent wishing to relocate with a child to provide the other parent at least 45 days written notice before the move. The other parent can file a petition to prevent the relocation, and a judge will decide based on the child's best interests. Relocating without proper notice can result in serious legal consequences, including loss of custody.

Yes, spousal maintenance (alimony) can be modified if there is a substantial and continuing change in circumstances, such as a significant income change for either party, remarriage of the recipient, or serious illness. The original decree must not have explicitly made the maintenance non-modifiable. File a Petition to Modify Spousal Maintenance in the issuing Superior Court.

You can file a Petition for Order to Show Cause (contempt of court) with the Superior Court that issued the original decree. If found in contempt, your ex may face fines, attorney's fee awards, or even jail time. Document every violation carefully with dates and details before filing.

Arizona offers several powerful enforcement tools including wage garnishment, bank account levies, interception of tax refunds, and suspension of a delinquent parent's driver's or professional license. The Arizona Department of Economic Security (DES) Division of Child Support Services can assist with enforcement at no cost.

Parenting time violations can be addressed by filing a Petition for Contempt or a Petition for Enforcement of Parenting Time with the Superior Court. Courts take these violations seriously and may sanction the offending parent with make-up parenting time, fines, or modification of the existing custody arrangement.

DIY filings typically cost $400–$600 in court filing fees. Attorney-assisted modifications range from $1,500–$3,500 for uncontested matters, while contested hearings can cost $15,000–$30,000 or more. Reaching a written agreement with your ex before filing can dramatically reduce both cost and time.

Yes — post-decree modification rules for child support, parenting time, and spousal maintenance apply equally to covenant marriages in Arizona. The covenant marriage designation affects the grounds required to obtain the original dissolution, but does not change the standards used to modify orders after the decree is entered.
