Types of Custody in Arizona
Arizona recognizes several types of custody arrangements:
| Type | Description |
|---|---|
| Legal Custody | The right to make major decisions about the child’s education, healthcare, and religious upbringing. |
| Physical Custody | Where the child primarily lives on a day-to-day basis. |
| Joint Custody | Both parents share legal custody, physical custody, or both. |
| Sole Custody | One parent has exclusive legal or physical custody. |
Joint custody presumption: YES — qualified. Arizona does not have a statutory presumption of exactly equal (50/50) parenting time, but ARS § 25-403.02(B) requires the court to “adopt a parenting plan that provides for both parents to share legal decision-making regarding their child and that maximizes their respective parenting time.” Arizona public policy under ARS § 25-103(B)(1) establishes that it is in the child’s best interest to have “substantial, frequent, meaningful, and continuing parenting time with both parents.” Arizona courts have held that a trial court commits reversible error by applying a presumption AGAINST equal parenting time. Equal parenting time is the “starting point” but not a mandatory outcome — the court must still apply the best interest factors. Joint legal decision-making is presumed unless the court finds it would not serve the child’s best interests.
Arizona Best Interest of the Child Standard
The best interests of the child standard is the primary framework Arizona courts use for all custody decisions. This standard considers what arrangement will best serve the child’s physical, emotional, and developmental needs.
Arizona courts evaluate these best interest factors when making custody decisions:
- Under ARS § 25-403(A)
- the court shall consider ALL relevant factors including: (1) The past
- present and potential future relationship between the parent and the child; (2) The interaction and interrelationship of the child with the child’s parent or parents
- the child’s siblings and any other person who may significantly affect the child’s best interest; (3) The child’s adjustment to home
- school and community; (4) If the child is of suitable age and maturity
- the wishes of the child as to legal decision-making and parenting time; (5) The mental and physical health of all individuals involved; (6) Which parent is more likely to allow the child frequent
- meaningful and continuing contact with the other parent (the “friendly parent” factor); (7) Whether one parent
- both parents or neither parent has provided primary care of the child; (8) The nature and extent of coercion or duress used by a parent in obtaining an agreement regarding legal decision-making or parenting time; (9) Whether a parent has complied with Chapter 3
- Article 5 of Title 25 (domestic relations education requirements); (10) Whether either parent was convicted of an act of false reporting of child abuse or neglect under ARS § 13-2907.02; (11) Whether there has been domestic violence or child abuse pursuant to ARS § 25-403.03. The court must make specific findings on the record about all relevant factors in a contested case.
Child’s preference: In Arizona, a child’s custody preference may be considered when the child reaches No specific age. Arizona uses a “suitable age and maturity” standard under ARS § 25-403(A)(4). The child’s wishes are one factor among many — never the sole determining factor. In practice, courts tend to give greater weight to preferences of children around age 12 and older, but this is discretionary. The court evaluates whether the child can express a thoughtful, logical reason for their preference. Note: SB1373 (2024) attempted to set age 14 as a threshold for child preference but did NOT pass into law (status: Dead).. The weight given to the child’s preference increases with age and maturity. The court considers the child’s reasoning and whether the preference is influenced by a parent.
Arizona Parenting Plans
Arizona requires parents to submit a parenting plan as part of custody proceedings. Under ARS § 25-403.02(A), a parenting plan must include at minimum: (1) A designation of legal decision-making as joint or sole as defined in ARS § 25-401; (2) Each parent’s rights and responsibilities for the personal care of the child and for decisions in areas such as education, health care, and religious training; (3) A practical schedule of parenting time for the child, including holidays and school vacations; (4) A procedure for the exchanges of the child, including location and responsibility for transportation; (5) A statement that each party has read, understands and will abide by the notification requirements of ARS § 25-403.05(B). The court may also determine other factors necessary to promote and protect the child’s emotional and physical health.
Key elements of an effective parenting plan:
- Regular residential schedule (weekdays, weekends, overnights)
- Holiday and school vacation rotation
- Transportation arrangements and pickup/drop-off logistics
- Decision-making authority (education, healthcare, extracurriculars)
- Communication methods between parents and between parent and child
- Dispute resolution process (mediation before court)
- Right of first refusal when a parent is unavailable
Arizona Custody Relocation Rules
Under ARS § 25-408, if both parents have joint legal decision-making or parenting time and both reside in Arizona, a parent must provide at least 45 days’ advance written notice (via certified mail) before relocating the child outside Arizona or more than 100 miles within the state. This applies even if the relocating parent has sole legal decision-making. The non-moving parent has 30 days after notice to petition the court to prevent the relocation. After those 30 days, a petition to prevent relocation may only be granted on a showing of good cause. The burden of proving the relocation is in the child’s best interests falls on the parent seeking to relocate.

Notice requirement: The relocating parent must provide 45 days advance written notice required (ARS § 25-408). Non-moving parent has 30 days to file a petition to prevent relocation. days advance written notice to the other parent.
The court evaluates whether the move serves the child’s best interests, considering the reason for the move, the impact on the child’s relationship with the non-moving parent, and whether a modified visitation schedule can preserve that relationship.
Modifying Arizona Custody Orders
Under ARS § 25-411, a motion to modify legal decision-making cannot be filed within one year of the original order UNLESS the court permits it based on affidavits showing reason to believe the child’s present environment may seriously endanger the child’s physical, mental, moral or emotional health. After one year, modification requires proof of a substantial and continuing change in circumstances AND that modification serves the child’s best interests. Parenting time may be modified whenever modification serves the child’s best interests, but the court shall not restrict parenting time unless it finds parenting time would seriously endanger the child’s health. Special exception: at any time after a joint legal decision-making order, a parent may petition for modification based on evidence of domestic violence (ARS § 13-1201 or § 13-1204), spousal abuse, or child abuse occurring since the original order.
Common modification triggers: parent relocation, change in child’s needs, substance abuse, domestic violence, parent’s work schedule change, child reaching an age where preferences are considered, or one parent consistently violating the existing order.
Special Circumstances in Arizona Custody
Domestic violence: Significant impact under ARS § 25-403.03. If the court finds that a parent has committed an act of domestic violence, there is a REBUTTABLE PRESUMPTION that awarding sole or joint legal decision-making to the offending parent is CONTRARY to the child’s best interests. The court SHALL NOT award joint legal decision-making if it finds significant domestic violence or a significant history of domestic violence. The offending parent bears the burden of proving that parenting time will not endanger the child or significantly impair the child’s emotional development. To rebut the presumption, the parent must demonstrate: (a) the award is in the child’s best interests; (b) completion of a batterer’s prevention program; (c) completion of alcohol/drug counseling if appropriate; (d) completion of a parenting class if appropriate; (e) no active protective orders if on probation/parole; (f) no further acts of domestic violence. The presumption does NOT apply if both parents committed acts of domestic violence.
Grandparent visitation: YES, under ARS § 25-409. Grandparents or great-grandparents may petition for visitation if it is in the child’s best interests AND at least one of the following is true: (1) One legal parent is deceased or has been missing for at least 3 months; (2) The child was born out of wedlock and the parents are not married to each other; (3) The parents’ marriage has been dissolved for at least 3 months. The court gives special weight to the legal parents’ opinion of what serves the child’s best interests. The court considers: the historical relationship between child and petitioner, the petitioner’s motivation, the amount of visitation requested, and potential adverse impact on the child’s activities. If a parent through whom the grandparent claims access has parenting time, the court shall order grandparent visitation during that parent’s time if logistically possible. Visitation rights automatically terminate if the child is adopted.
Unmarried parents: An unmarried father must first establish paternity before asserting any rights to legal decision-making or parenting time. Without paternity establishment, the mother has sole legal custody by default. Paternity may be established by: (1) voluntary acknowledgment of paternity (both parents signing a form at the hospital or later); (2) court-ordered DNA/paternity test; or (3) court adjudication. Either parent, a guardian, conservator, or public welfare agency may file a paternity petition under ARS § 25-803. Once paternity is established, the father has equal rights to petition for legal decision-making and parenting time — the same best interest factors under ARS § 25-403 apply to both married and unmarried parents.
Guardian ad litem: YES. Arizona courts may appoint a best interests attorney, child’s attorney, or court-appointed advisor (CAA) under ARS § 25-405. A court may appoint a guardian ad litem when there are allegations of child abuse or neglect, persistent significant parental conflict, history of substance abuse or family violence, serious concerns about a parent’s mental health, when the child is an infant/toddler or has special needs, or for any other reason the court deems appropriate. ARS § 25-405 also allows the court to order a custody evaluation by a qualified evaluator or mental health professional. The appointment order must state its terms, reasons, duration, rights of access, and compensation.
Additional Arizona rules: (1) TERMINOLOGY: Arizona eliminated the word “custody” from its family law statutes effective January 1, 2013, replacing it with “legal decision-making” (major decisions about education, healthcare, religion, personal care) and “parenting time” (physical schedule). (2) SPLIT DECISION-MAKING: A judge may grant joint legal decision-making overall but give one parent final authority in a specific area (e.g., education or healthcare) when parents consistently cannot agree. (3) FRIENDLY PARENT FACTOR: ARS § 25-403(A)(6) specifically requires the court to consider which parent is more likely to allow the child frequent, meaningful and continuing contact with the other parent — this can weigh heavily in contested cases. (4) FALSE REPORTING: ARS § 25-403(A)(10) — a conviction for false reporting of child abuse or neglect (ARS § 13-2907.02) is an explicit best-interest factor working against that parent. (5) MAXIMIZATION MANDATE: ARS § 25-403.02(B) requires the court to maximize each parent’s respective parenting time, consistent with the child’s best interests. (6) ONE-YEAR BAR: Under ARS § 25-411, modification of legal decision-making generally cannot be sought within one year of the original order absent serious endangerment.
