Changing A Court Order, Or Making Someone Follow It
Once a court order is in place in Arizona it is legally binding, and every party has to follow it. Life does not always cooperate. Circumstances change, and sometimes one party stops complying.
There are two separate remedies for that, and they are not interchangeable. A modification changes what the order says. Enforcement makes someone follow the order that already exists.
What A Modification Does
A modification is the court reviewing an order it already issued and changing its terms. In family law these are most often child custody and child support orders. One parent asks the court for the change, and generally needs to show that circumstances have shifted significantly since the order was entered.
- Child custody and parenting time
- Child support
- Spousal support
- Parenting plans and visitation schedules
What Enforcement Does
Enforcement is the court stepping in to make a party follow the terms already in place. It protects spouses and children from the harm that follows when one party simply stops complying. Until a modification is granted, the existing order still stands and can be enforced.
- Support goes unpaid
- Parenting time is withheld or missed
- A parenting plan is ignored
- Any ordered term is refused
Orders That Can Be Modified In Arizona
An existing order can be revisited when new evidence or new circumstances affect it. The court puts a child’s stability first, so it takes a significant change, or evidence that a parent is unfit, before an order is revisited.
Child Custody Agreements
Custody arrangements commonly need adjusting as children age and their needs change. Work schedule changes, a sudden change in a parent’s or child’s health, or one parent relocating can all warrant a modification.
Child Support Orders
These can be modified when there is a substantial change in either parent’s financial resources, such as a job loss, a significant raise or pay cut. They can also change when the child’s own costs shift, through medical bills or education expenses.
Parenting Plans & Visitation
Like custody orders, these often need revisiting as children get older and their needs change. A parent moving, or a change in work schedule, can create the same need.
Spousal Support
A change in either spouse’s financial position can justify altering a support order. Remarriage, cohabitation, a major change in income, a job loss, or sudden health issues may all be grounds.
Why People Ask For A Modification
Spousal support, child support and custody all rest on circumstances that can change. These are the changes that most often justify going back to the court.
Relocation
One parent needs to move a significant distance, which puts the existing custody arrangement back in question.
Parental Fitness
A parent develops a mental health or substance use disorder, and the other parent seeks a change to the current orders.
Income & Financial Change
A job loss, a raise or pay cut, or a change in health insurance can call for altering a child support or spousal support order.
Other Life Changes
One party remarries or begins cohabiting with someone, or a parent passes away.
Military Deployment
A parent is deployed or receives orders to relocate, which can require the custody order to change with it.
Endangerment & Refusal To Comply
A parent poses a risk to the child through abuse, neglect, illegal activity or substance use. Persistent refusal to follow the order can support a modification too, alongside an enforcement action.
A Child’s Changing Needs
As children grow, their education costs, medical needs or disabilities can change enough to require a different custody or support arrangement.
When Enforcement Is Needed
These are the situations that most often bring a party back to court asking for the existing order to be enforced.
Unpaid Support
One party refuses to pay the child support or spousal support set out in the decree.
Missed Parenting Time
A parent does not keep to the parenting schedule. That is more than an inconvenience; it goes to the child’s wellbeing.
Parenting Plan Violations
A parent ignores the plan, for instance by refusing to return the child when their parenting time ends.
Ignoring Court-Ordered Terms
Any term of a finalized order that one party will not comply with can be brought back to the court by the other party.
The Steps For Each Route
The two remedies follow different paths through the court. Here is what each one involves.
Modification
- Identify and clearly define the change in circumstances that justifies revisiting the order.
- File a petition with the court setting out the evidence of that change.
- Serve the other party through process service, giving them time to respond.
- Attempt mediation or negotiation, which can be required before the matter is heard.
- If no agreement is reached, proceed to a hearing where the judge decides whether the change is warranted.
- If the judge agrees, a new order is entered replacing the original terms.
Enforcement
- Document every violation: missed exchanges, unpaid child support, unpaid spousal support.
- File a petition asking the court to enforce the order.
- File a motion for contempt to hold the non-compliant party responsible.
What The Court Is Actually Weighing
When a request is filed, the court looks at all the evidence and surrounding circumstances to decide whether a significant change has actually occurred, and whether it justifies modifying or enforcing the order.
In custody matters the child’s best interests are the court’s highest priority. Arizona sets a deliberately high bar before a court will restrict a parent’s time with their child, and courts do not reach that point lightly.
What the court wants to see is that a parent can provide a stable, nurturing environment and will take on the responsibilities of meeting the child’s needs. Its focus stays on the child’s safety, health, development and happiness, whatever else is going on in the case.
A strong case shows the court what your child’s day-to-day life actually looks like, and what it would look like after the change.

Modification & Enforcement FAQs
Can I Modify An Order Without Going To Court?+
Sometimes. If you and your former spouse can reach an agreement in mediation, an order can be modified without a contested hearing. If mediation does not produce an agreement, the matter goes to court and a judge determines the final terms.
What Evidence Do I Need For A Modification?+
It depends on the modification you are seeking. Evidence might include proof of a change in income, documentation of a change in the child’s needs, proof that a parent can no longer pay support, or proof of changes to health insurance or childcare.
What Happens If The Other Parent Refuses To Comply?+
You can file a motion to enforce the order. A parent who will not comply may be found in contempt of court, which carries additional penalties.
How Long Does The Process Take?+
There is no fixed timeframe. Matters involving child support often run several months. How long yours takes depends on how quickly information reaches the court, how complex the matter is, and the court’s own scheduling.
Do I Need A Lawyer For These Cases?+
You are not required to have one. But a family lawyer gives you guidance that is hard to replace, and that matters more the more complex your case is.
