Life changes after a custody order is finalized in Arizona, and sometimes those changes are significant enough that the original parenting plan no longer works. Other times, one parent simply stops following the order altogether, leaving the other parent unsure of what recourse is available. Both situations raise real questions: when can a custody order actually be modified, and what happens when someone refuses to follow one?

Arizona family courts take custody orders seriously, and for good reason. Constant requests to revisit custody arrangements create instability for children and drag parents back into conflict long after their case should have been resolved. At the same time, the law recognizes that circumstances evolve, and it provides a path for parents to seek changes when those changes genuinely serve a child’s best interests. Understanding how modification and enforcement work in Arizona can help you know where you stand and what your next step should be.

Why Arizona Limits Custody Modifications in the First Year

When a custody order is put in place in Arizona, it is generally meant to stay in effect for at least one year before either parent can ask the court to change it. The reasoning behind this rule is straightforward. Courts want to avoid a revolving door of hearings where parents are constantly back in the courtroom relitigating parenting time and decision making authority. That kind of ongoing conflict is hard on children and makes it difficult for either household to settle into a stable routine.

There is an exception to the one year rule, but it is a narrow one. If a child would be irreparably harmed by waiting out the year, a parent can ask the court to intervene sooner. That standard is intentionally high. Courts expect substantial evidence before disrupting an order early, so this path is reserved for genuinely serious circumstances rather than everyday disagreements between parents.

The Standard for Modifying a Custody Order After One Year

Once a year has passed, a parent seeking to modify custody must show that there has been a substantial and continuing change of circumstances since the order was entered. This is not a bright line rule with a fixed checklist. Instead, it is a flexible standard that depends heavily on the specific facts of each family’s situation.

Some of the more common examples Arizona courts consider include a child reaching school age and needing a different schedule, parents relocating farther apart so that the existing parenting time arrangement is no longer logistically workable, or one parent being habitually unable to participate in legal decision making in a way that creates ongoing stalemates over things like therapy, medical care, or schooling. There are countless variations on these themes, and what qualifies as a substantial change in one family’s case may look completely different in another. That is part of why it helps to talk through your specific circumstances with an attorney rather than trying to match your situation to a generic list.

It is also worth remembering that disagreeing with an existing order, or simply preferring a different arrangement, is not the same as showing a substantial and continuing change of circumstances. The court is looking for a meaningful shift in the underlying facts, not just a shift in one parent’s preferences.

What to Do When a Custody Order Is Not Being Followed

Modification is not the only issue that comes up after a custody order is entered. Just as often, one parent is following the order and the other is not. Maybe parenting time exchanges are not happening as scheduled, or one parent is making unilateral decisions that were supposed to be shared.

If you believe your child’s other parent is violating the custody order, the appropriate response is to file a petition asking the court to enforce it. This is true even if you think the current order is unfair or outdated. Arizona law does not allow a parent to simply decide, on their own, to stop following an order they disagree with. If you believe the order should change, the correct path is to request a modification through the court, not to unilaterally deviate from what has already been ordered.

The distinction matters because courts in Arizona take violations of custody orders seriously, and choosing to ignore an order rather than seeking a legal change to it can expose a parent to real consequences.

Sanctions and Penalties for Violating a Parenting Plan

When a parent is found to have violated a parenting plan, Arizona courts have a range of tools available to address it. One common remedy is requiring the violating parent to pay the other parent’s attorney’s fees incurred in bringing the enforcement petition. Courts can also order a parent to pay a set amount, such as $100, for every day of parenting time that the other parent missed because of the violation.

These are not the only options. Depending on the severity and frequency of the violations, a court can consider other sanctions as well, and in situations where a parent habitually and repeatedly disregards custody orders, jail time is a real possibility. Arizona courts do not take these issues lightly, and a pattern of violations can escalate the consequences considerably.

If you are dealing with a co-parent who will not follow the custody order, or if you have been accused of violating one yourself, these are not situations to navigate without guidance. Having an attorney walk you through the process, whether you are filing the petition or responding to one, can make a meaningful difference in how the case unfolds.

Getting the Right Guidance for Your Situation

Whether you are wondering if enough has changed to justify modifying your custody order, or you are trying to get an existing order enforced, these cases involve real legal standards and real consequences. What counts as a substantial change of circumstances in one family’s case will not necessarily apply to yours, and the process for enforcing an order correctly is not always intuitive.

Talking with an attorney early can help you understand where your situation stands, what evidence will matter, and what to expect as your case moves forward. Custody issues are personal and often emotional, and having someone who understands Arizona family law walk alongside you can help you move through the process with more clarity and less uncertainty.
