Arizona courts determine legal decision-making (custody) and parenting time (visitation) based on the child's best interests under A.R.S. § 25-403. Arizona uses unique terminology and requires a detailed parenting plan, an automatic preliminary injunction at filing, and completion of a Parent Education Program.
This comprehensive guide covers Arizona's best interest factors, legal decision-making types, the parenting time credit system, the 60-day waiting period, mandatory education requirements, and Income Shares child support calculations.

Arizona's Best Interest Factors
Under A.R.S. § 25-403, Arizona courts must consider multiple factors when determining legal decision-making and parenting time:
- Parent-child relationship: The past, present, and potential future relationship between each parent and the child
- Child's adjustment: The child's adjustment to home, school, and community
- Child's wishes: If the child is of suitable age and maturity
- Mental and physical health: Of all individuals involved
- Meaningful contact: Which parent is more likely to allow frequent, meaningful, and continuing contact with the other parent
- Domestic violence: Whether there has been domestic violence or child abuse
- Coercion or duress: Whether a parent used coercion or duress to obtain an agreement
- Compliance: Whether a parent has complied with court orders
- False reporting: Whether a parent has been convicted of making a false report of child abuse or neglect
Important: Under A.R.S. § 25-403.03, courts cannot award joint legal decision-making where there has been significant domestic violence. Lesser domestic violence creates a presumption against awarding sole or joint decision-making to the perpetrator.
Legal Decision-Making Types
Arizona uses the term "legal decision-making" instead of "custody" to describe decision-making authority:
Joint Legal Decision-Making
- Both parents share the right and responsibility to make major decisions about the child
- Includes decisions about education, healthcare, religious training, and personal care
- Does not require equal parenting time
Sole Legal Decision-Making
- One parent has exclusive authority to make major decisions
- The other parent typically still has parenting time
- May be appropriate when parents cannot communicate or cooperate effectively

Parenting Schedule Calculator
Visualize common custody schedules and calculate parenting time percentages. See how different schedules work for your child's age and your co-parenting situation.
Select Your Situation
50/50 Equal Time Schedules
Child spends one full week with each parent, alternating every week.
Child alternates between 2 days with each parent, then 3 days, ensuring no more than 3 days apart.
Each parent has the same weekdays every week, with alternating 5-day weekends.
Alternating 3 and 4-day blocks provide balance between contact frequency and stability.
Unequal Time Schedules
Child lives primarily with one parent, spending every other weekend with the other parent.
Every other weekend plus one overnight during the week increases non-custodial parent time.
One parent has 4 days, the other has 3 days each week, creating a 60/40 split.
Different ages have different developmental needs
Alternating Weeks (Week-On/Week-Off)
Child spends one full week with each parent, alternating every week.

Parenting Plan Requirements
Under A.R.S. § 25-403.02, every Arizona parenting plan must include:
- Decision-making designation: Whether joint or sole legal decision-making
- Residential schedule: A detailed schedule including weekdays, weekends, holidays, school breaks, and special occasions
- Exchange provisions: Where and how custody exchanges will occur
- Dispute resolution: A process for resolving future disagreements (mediation, arbitration, or court)
- Communication protocols: How parents will communicate about the children and how the child will communicate with each parent
Automatic Preliminary Injunction
Under A.R.S. § 25-315, an automatic preliminary injunction takes effect when you file for divorce. This restrains both parties from:
- Transferring, selling, or hiding community property (except for normal expenses)
- Molesting or harassing the other spouse or children
- Removing the children from Arizona without consent or court permission
- Removing the other party or children from existing insurance coverage
The injunction binds the petitioner upon filing and the respondent upon service. It remains in effect until the case is dismissed or the final decree is entered.
Residency and Waiting Period
Arizona has specific requirements before filing and finalizing a divorce:
- 90-day residency: Under A.R.S. § 25-312, at least one spouse must be domiciled in Arizona or stationed here on military duty for 90 days before filing
- 60-day waiting period: Under A.R.S. § 25-329, no decree can be entered until 60 days after service or acceptance of the petition
- Home state for children: Arizona must be the child's "home state" (6 months residency) to make custody orders
Parent Education Program
Under A.R.S. § 25-352, Arizona courts must order both parents to attend an educational program when custody, parenting time, or support is at issue:
- Programs address the impact of divorce on children and co-parenting strategies
- County-specific programs are available (in-person or online)
- Fees vary by county and provider (typically $40-$100)
- Exceptions may be granted in certain circumstances

Child Support Under Arizona Guidelines
Arizona uses the Income Shares model under A.R.S. § 25-320 and the 2022 Arizona Child Support Guidelines. Both parents' incomes are combined to estimate what would have been spent on children in an intact household, then divided proportionally.
Key Support Thresholds (2025)
- Combined income cap: $30,000/month Combined Adjusted Child Support Income (CACSI)
- Self-support reserve: $2,038.40/month (80% of full-time minimum wage at $14.70/hour)
- Minimum order: No order if calculated amount is less than $8/month (clearinghouse handling fee)
- Older-child add-on: +10% to the support portion for each child age 12 or older

Support Duration and Termination
Arizona child support follows specific termination rules:
- Standard termination: Age 18
- High school exception: Continues while actually attending high school or equivalency program, but not beyond age 19
- Disabled adult children: Support may continue if the child has severe mental or physical disabilities that began before majority
Interest on Arrears

Relocation Requirements
Under A.R.S. § 25-408, a parent with joint legal decision-making or parenting time must provide 45 days' advance written notice before relocating:
- Out of Arizona, OR
- More than 100 miles within Arizona
The non-relocating parent may petition to prevent the relocation. Courts consider the impact on the child's relationship with both parents.
Modifying Orders
Arizona allows modification under specific circumstances:
Support Modification
- Standard: Requires a "substantial and continuing change" in circumstances
- Simplified procedure: Available if recalculation differs by 15% or more from the current order
- Effective date: Generally the first day of the month after notice of the petition
Parenting Time Modification
- Requires a change in circumstances affecting the child's best interests

Arizona provides robust enforcement through the Division of Child Support Services (DCSS):

- Tax refund intercepts: Federal ($500+ arrears) and state refunds applied to arrears
