Arizona Child Custody: The "Best Interest" Factors

Arizona courts decide custody (called "legal decision-making" and "parenting time") using a list of best-interest factors set by statute. The factors aren't ranked — judges weigh them all together based on the specific family. Knowing what's on the list helps you focus your case on what actually matters.

1. The relationship between each parent and the child

Courts look at history of caretaking, bonding, and involvement — not who earns more. A parent who has consistently been the primary caregiver typically gets weight here.

2. The child's relationships with siblings and others

Existing bonds with siblings, extended family, friends, schools, and community count. Disruption matters — courts try not to upend a child's whole life when avoidable.

3. The child's adjustment to home, school, and community

If a child is thriving in a particular school or neighborhood, courts hesitate to move them away. If they're struggling, courts may consider whether a different environment would help.

4. The mental and physical health of everyone involved

Untreated mental health issues, addiction, or domestic violence can dramatically affect what the court orders. So can a parent's history of addressing those issues responsibly.

5. Cooperation, communication, and good faith

ARS §25-403 explicitly weighs which parent is more likely to encourage the child's relationship with the other parent. Badmouthing or interfering can backfire badly in court.
