If your co-parent wants to move with your children — or if you're the one who needs to move — Arizona law sets strict rules about when and how it can happen. The good news: you have rights either way. The hard part: the clock starts ticking the moment notice is given, and missing a deadline can end the fight before it starts.
When Arizona's relocation rules apply
The 45-day notice rule applies in a specific set of circumstances. All of these must be true:
- Both parents have legal decision-making rights, parenting time, or both by court order or written agreement
- Both parents currently live in Arizona
- The proposed move is either out of state or more than 100 miles within Arizona
If you're moving across town or even across the Valley, the relocation statute doesn't apply — though you still need to keep the other parent informed of your new address. If one parent already lives out of state, different rules apply under the Uniform Child Custody Jurisdiction and Enforcement Act (UCCJEA).
If you want to move with your children
The procedure is narrow and unforgiving of mistakes:
- Send written notice to the other parent at least 45 days before the planned move. It must be sent by certified mail with return receipt requested, or served under the Arizona Rules of Family Law Procedure.
- Include the destination in the notice — address, contact information, and reasons for the move.
- Wait 30 days. If the other parent doesn't file a petition to prevent relocation, you can generally proceed.
- If they object, prepare for a hearing. The burden of proving the move is in the child's best interests falls on you.
If your co-parent wants to move with your children
You have 30 days from receiving notice to file a petition with the court asking to prevent the relocation. Miss this window and you lose the right to object in most cases, so don't wait.
Once you file, the court will hold a hearing. The judge applies the best interests of the child standard under A.R.S. § 25-408(I), looking at factors including:
- The reasons for the move (and the reasons for opposing it)
- The impact on the non-moving parent's ability to maintain a relationship with the child
- Whether the move is motivated by a desire to interfere with the other parent's relationship
- The potential benefit to the child's quality of life
- The likelihood the relocating parent will comply with future parenting time orders
- The feasibility of a realistic parenting time schedule after the move
- The child's age, relationships, and stability
- The child's wishes, if old enough to express a reasoned preference
What happens if a parent just moves without notice
This is where people get into real trouble. Moving a child out of state or more than 100 miles without notice, or over the other parent's objection without court approval, can have serious consequences:
- The court can order the child returned to Arizona immediately
- Attorney's fees and court costs can be assessed against the moving parent
- Custody can be modified in the non-moving parent's favor
- In extreme cases — particularly across state lines without notice — criminal charges for custodial interference or parental kidnapping are possible under A.R.S. § 13-1302
The 100-mile rule inside Arizona
Arizona is a geographically large state. A move from Phoenix to Tucson (roughly 115 miles) triggers the statute. Phoenix to Flagstaff (about 145 miles) does too. Even Phoenix to Prescott (roughly 100 miles) can qualify depending on exact distances.
If you're close to the threshold, don't assume. Measure driving distance and, if unclear, treat the move as if the statute applies. Following the notice procedure when you didn't have to costs you nothing. Not following it when you should have can cost you custody.
Sole custody and relocation
Having sole legal decision-making does not mean you can move freely. The statute still applies. If the other parent has any court-ordered parenting time, you need to give the 45-day notice. Legal decision-making and physical location are separate issues in Arizona family law.
The exception is when the other parent has no parenting time and no legal decision-making rights — in that case, the relocation rules generally don't restrict the custodial parent. But this is rare and fact-specific.
How the court actually decides relocation cases
In contested relocation cases, outcomes usually depend on how well each parent addresses the statutory factors. The moving parent's strongest arguments are usually:
- A concrete, specific employment or educational opportunity that substantially improves the family's circumstances
- A support system (family, community) in the destination
- Specific proposals for how the other parent's relationship with the child will be maintained — extended summer visits, holidays, technology
- Willingness to share travel costs
The non-moving parent's strongest arguments are usually:
- Strong existing bond with the child, demonstrated by consistent parenting time
- Stable, high-quality current circumstances for the child (school, community, extended family)
- Evidence that the motivation for the move is something other than the stated reason — particularly to interfere with the relationship
- A concrete proposal for what happens if the court denies relocation (for example, the non-moving parent assumes primary parenting time if the moving parent moves anyway)
What to do in the first 24 hours after you learn about a move
Whether you're planning a move or just received notice of one, the first day matters:
- Document everything. Keep the written notice. Save emails and texts about the move.
- Do not agree to anything in writing that you haven't thought through carefully. Courts treat written agreements as binding.
- Count the days. If you're objecting, you have 30 days from receipt of notice. Mark the deadline on a calendar today.
- Talk to a family law attorney. Relocation cases are among the most fact-specific in family law; a 30-minute consultation usually clarifies whether you have a strong case.
Frequently asked questions
Can my child choose which parent to live with?
Arizona doesn't have a bright-line age at which a child's preference is controlling. Judges may consider the preferences of a child who is old enough to express a reasoned preference — generally somewhere around age 12 and up — but the child's wishes are one factor among many, not a veto.
Does it matter why my ex wants to move?
Yes, significantly. Motives are an explicit statutory factor. Moves for genuine career advancement, education, or remarriage tend to be received more favorably than moves that appear motivated by distance from the other parent.
What if we agree on the move?
If both parents agree, you can submit a stipulated modification to the court and avoid a contested hearing entirely. Get the agreement in writing, file it with the court, and have it made a formal order. Verbal agreements are not enforceable in family court.
Can the non-moving parent still object if I've already given notice?
Yes — that's exactly what the 30-day window is for. Giving notice doesn't entitle you to move; it starts the clock for the other parent to challenge.
What if my ex moves with our child before I can object?
File an emergency motion immediately. Arizona courts can and do order children returned when a parent violates the notice requirements. Speed matters — the longer the child is in the new location, the more the court has to weigh established stability.
How much notice do I have to give before relocating with my child in Arizona?
Under A.R.S. § 25-408(A), a parent who shares legal decision-making or parenting time and intends to move the child either outside Arizona or more than 100 miles within Arizona must give the other parent written notice at least 45 days in advance. The notice must be sent by certified mail, return receipt requested. The 45-day clock gives the other parent time to petition the court to prevent the relocation. Skipping notice — or moving before the period expires — exposes you to emergency court orders, contempt findings, and a presumption against the relocation in any later best-interests review. Send the notice certified, and document everything.
What happens if the other parent objects to the relocation?
Under A.R.S. § 25-408(B), the non-relocating parent has 30 days from the date of the notice to file a petition with the court asking the judge to prevent the relocation (or to modify parenting time if the move proceeds). If the petition is filed, you cannot move the child until the court rules — and the moving parent bears the burden of proving the relocation is in the child's best interests under the eight factors in A.R.S. § 25-408(I). If no petition is filed within 30 days, the relocation can proceed. Even then, keep a copy of the certified-mail receipt and the un-filed-objection timeline in case parenting time needs to be modified later.
Does the Arizona court consider the child's wishes for relocation?
Yes, but the child's wishes are one factor among many. A.R.S. § 25-408(I) directs the court to consider the eight enumerated relocation factors, which incorporate the broader best-interests test in A.R.S. § 25-403. Under A.R.S. § 25-403(A)(4), the court considers "the wishes of the child as to the legal decision-maker and parenting time" — but only when the child is old enough to form and express a reasoned preference. There is no bright-line age; Arizona judges generally start giving meaningful weight to a child's preference around age 12, though younger children with mature reasoning may be heard. A child's preference never overrides the best-interests analysis as a whole — it is evidence, not a veto.
Can a parent relocate within Arizona without court approval?
It depends on distance. A.R.S. § 25-408(A) only applies when (a) the relocation is out of Arizona, OR (b) the move is more than 100 miles from the current residence within Arizona. Moves of less than 100 miles within Arizona generally do not require advance notice or court approval — though if the move significantly affects the existing parenting-time schedule (e.g., school district change, commute distance for visitation), the other parent can still petition under A.R.S. § 25-411 to modify the parenting plan. Practically: if you're moving across town, you don't need court permission, but if you're moving from Phoenix to Tucson (~120 miles), you do. When in doubt, give notice anyway — it's the cheap insurance.
What factors do Arizona courts use to decide relocation cases?
A.R.S. § 25-408(I) lists eight factors the court must consider when ruling on a contested relocation: (1) the factors in A.R.S. § 25-403 (the standard best-interests test); (2) whether the move is being made in good faith or to interfere with the other parent's contact; (3) the prospective advantage of the move in improving the general quality of life for the relocating parent and child; (4) the likelihood that each parent will comply with future parenting time orders; (5) whether the court will be able to fashion a reasonable parenting time schedule if the move is allowed; (6) the reasons each parent supports or opposes the move; (7) the relationship between the child and each parent and significant others; and (8) practical considerations like the age and developmental needs of the child. The moving parent has the burden of proof.
What if I have sole custody — do I still need court approval to relocate?
A.R.S. § 25-408 applies when "joint legal decision-making" or parenting time has been ordered — meaning the 45-day notice and 30-day objection structure is most clearly triggered in joint-custody and shared-parenting-time cases. If you have sole legal decision-making AND the other parent has no court-ordered parenting time, you generally have more latitude to relocate. However, if the other parent has any court-ordered parenting time (even minimal visitation), the relocation statute still applies — sole legal decision-making is not the same as sole physical custody. Even where the statute may not strictly require it, giving notice and seeking a written modification protects you against later contempt actions and is the path most family-law attorneys recommend.
How long does the relocation court process typically take?
If both parents agree on the relocation and submit a stipulated modification, the process can finish in 4-8 weeks — basically just the time the court needs to docket and sign the order. A contested relocation is much longer. After the petition is filed under A.R.S. § 25-408(B), expect: 30-60 days for initial response and discovery; 60-120 days for a temporary orders hearing if needed (parenting time during the pendency); and 6-12 months for a final evidentiary hearing, depending on the county's docket. Maricopa and Pima counties typically run 9-12 months; smaller counties can be faster. Plan for at least 6 months, and don't move the child until the court rules — moving prematurely can be devastating to your case.
