Child Custody in Phoenix: What the Law Actually Says
Arizona hasn't used the word "custody" in its statutes since 2013, and the rules are more specific, and less automatic, than most people assume. Here's what actually determines the outcome.
Reviewed for accuracy against Arizona Revised Statutes § 25-403 and § 25-403.02, 2026.
The Most Common Misconception
Is Arizona a 50/50 Custody State?
Not by statute. There is no Arizona law that guarantees equal parenting time. What the law requires, under A.R.S. § 25-403.02, is that courts give each parent the maximum time consistent with the child's best interests. In practice, many Phoenix-area judges do start from something close to an equal split when both parents are fit and able to cooperate. But the final arrangement always comes down to eleven specific factors, not a default percentage.
The 11 Factors a Judge Must Weigh
Under A.R.S. § 25-403, an Arizona court must consider each of these and put written findings on the record. None of them alone decides the outcome.
- 1 Each parent's past, present, and future relationship with the child
- 2 The child's own wishes, if old enough to express a reasoned preference
- 3 Interaction with parents, siblings, and anyone else affecting the child's best interest
- 4 The child's adjustment to home, school, and community
- 5 The mental and physical health of everyone involved
- 6 Which parent is more likely to allow frequent, meaningful contact with the other
- 7 Whether one parent intentionally misled the court to delay or avoid resolution
- 8 Cooperation between parents in decisions about the child
- 9 Whether domestic violence has occurred
- 10 Whether either parent has used coercion or duress to reach a custody agreement
- 11 Compliance with a parent's court-ordered attendance at parenting classes
Two Separate Questions, Not One
Legal Decision-Making
Who decides on schooling, medical care, and religious upbringing. Can be joint or sole, regardless of how time is split.
Parenting Time
The actual schedule of where the child lives and stays. Decided separately from decision-making authority.
A parent can hold joint legal decision-making while having far less than half the parenting time, or the reverse. Courts treat the two as independent questions, and a parenting plan needs to address both.

Questions People Ask
Frequently Asked, Answered Straight
Is Arizona a 50/50 state for child custody?
Not by statute. Arizona has no law guaranteeing automatic equal parenting time. What the law requires, under A.R.S. § 25-403.02, is that courts maximize each parent's time with the child when it's consistent with the child's best interests. In practice, many judges do start from a roughly equal-time framework when both parents are fit and cooperative, but the final decision rests on 11 specific factors under A.R.S. § 25-403, not an automatic default. A parent who has been largely absent, has safety concerns raised against them, or works a schedule incompatible with equal time should expect the court to deviate from a 50/50 split.
How much does a custody lawyer cost in Arizona?
For an uncontested case where both parents largely agree, total costs including filing fees typically land between $500 and $2,000. Contested cases, especially ones involving disputes over relocation, substance abuse allegations, or extensive discovery, commonly run from $5,000 to $30,000 or more, since attorney rates in the Phoenix area generally fall between $250 and $500 per hour. Filing fees themselves are separate: Maricopa County charges around $349 to $360 for a custody or dissolution petition, plus roughly $50 per parent for the mandatory Parent Information Program.
What is the biggest mistake parents make in a custody battle?
Treating the other parent as the opponent instead of treating the case as a negotiation over the child's needs. Judges weighing the 11 best-interest factors under A.R.S. § 25-403 specifically look at each parent's willingness to foster a relationship between the child and the other parent. Parents who badmouth the other parent in front of the child, withhold parenting time out of spite, or ignore the parenting plan once it's in place tend to hurt their own case far more than they hurt the other side.
What's the difference between legal decision-making and parenting time?
Arizona dropped the word 'custody' from its statutes back in 2013. Legal decision-making is the authority to make major decisions about a child's education, healthcare, and religious upbringing. Parenting time is the actual schedule of where the child physically lives and stays. A parent can have joint legal decision-making with unequal parenting time, or the reverse; the two are decided separately, not as a package.
Can I change a custody order later if circumstances change?
Yes. Either parent can petition to modify legal decision-making or parenting time if there's been a substantial and ongoing change in circumstances, things like a parent relocating, a major shift in work schedule, or new concerns about the child's safety or well-being. Courts don't revisit orders over minor disagreements; the change has to be significant and lasting.
