When parents separate, one of the most important—and often most contested—questions is how important decisions will be made for their children and how parenting time will be divided.
In Arizona, courts do not simply award custody to one parent over the other. Instead, judges are required to evaluate what arrangement serves the best interests of the child based on a number of statutory factors.
Understanding how these decisions are made is essential, particularly in cases involving high conflict, complex schedules, or significant financial and logistical considerations.
Legal decision-making vs. parenting time
Arizona distinguishes between two components of custody:
- Legal decision-making: Authority to make major decisions (education, healthcare, religion)
- Parenting time: The schedule for when the child is with each parent
These can be shared jointly or allocated differently depending on the circumstances. Although they are both determined considering the same statutory factors, they are independent concepts. One parent could be awarded sole legal decision-making authority while the other parent has the majority of parenting time, for example.
Arizona's "best interests of the child" standard
Arizona law centers all child custody decisions on what serves the child’s best interests—not the preferences of either parent.
Rather than applying a rigid formula, courts evaluate the totality of the circumstances, which gives judges broad discretion in determining outcomes.
This means that how a case is presented—and how each parent’s role is demonstrated—can significantly influence the final result. This can be one of the biggest reasons to consider hiring an experienced child custody lawyer to help you. Child custody orders are modifiable, but not always immediately. So a negative outcome can have lasting implications for the parents and the children.
Joint custody vs. sole custody in Arizona
Courts generally prefer arrangements that allow both parents to remain involved in the child’s life—so much so that the term "sole custody" is kind of a myth. Parents are very rarely excluded from seeing their children, even if circumstances require parenting time to supervised.
However, joint legal decision-making (or legal custody) not automatic. It depends on:
- The parents’ ability to cooperate
- The level of conflict
- Any concerns affecting the child’s well-being
In more complex or high-conflict cases, courts may structure parenting plans with significant detail to minimize future disputes. Courts can award sole legal decision-making to on parent even when they award equal parenting time to both parents. Courts also can give one parent "final say" authority over all legal decisions or specific categories of decisions whenever the judge is concerned that parents may be unable to cooperatively make those decisions.
While equal parenting time and joint legal decision-making are typically the starting point for family courts, they are not legal presumptions. This means that family courts are not required to award equal parenting time or joint legal decision-making even when parents are perfectly fit. Judges have a lot of discretion, so it is very important to have an experienced child custody lawyer on your side if you and the other parent cannot agree to a parenting plan.
The key factors family courts consider
Judges in Arizona are required to consider all "relevant" factors, including:
The relationship between each parent and the child
Courts look at the strength, consistency, and history of each parent’s relationship with the child.
Each parent’s ability to care for the child
This can include:
- Housing consistency
- Work schedules
- Ability to meet the child’s daily needs
Each parent's willingness to support the other parent's relationship
Courts favor parents who encourage a healthy relationship between the child and the other parent.
The child’s adjustment to home, school, and community
Disrupting a child’s routine can be a significant consideration, particularly in established environments. Family courts generally don't want children to be removed from their school, their customary extracurricular activities, or their friend groups.
The mental and physical health of the parents and the children
Any condition that affects parenting ability may be considered. This can invite uncomfortable scrutiny for parents with private medical conditions. Those sensitive medical records may be relevant and discoverable during the litigation.
History of domestic violence or substance abuse
Similarly, these issues carry significant weight and can alter custody outcomes entirely. Evidence of domestic violence or substance abuse can invoke statutory presumptions against joint legal decision-making and can justify restriction of a parent's parenting time.

Circumstances that can complicate custody determinations
While many cases follow predictable patterns, others involve more nuanced considerations, such as:
- Relocation or distance between parents' homes
- Blended family dynamics
- Demanding professional schedules, particularly those requiring business travel
- Involvement of third-parties like grandparents or guardians
- High-conflict communication dynamics
In these situations, custody outcomes often depend on how effectively each parent’s position is developed and presented. This often can be too technical for parents to do it without hiring a lawyer.
Third party rights and visitation
Arizona law allows non-parents who function "in the role of a parent" to petition to establish third party rights over non-biological children. These cases commonly involve stepparents, grandparents, or other relatives who care for children for extended periods of time. Third parties can be awarded legal decision-making authority and/or "physical placement" of the children, meaning that the children can be ordered to live with these third parties. Biological parents can be ordered to pay child support to third party caretakers.
Third party visitation sounds very similar to third party rights, but it is actually very different. Third party visitation allows anyone with a relationship with children to petition the court for visitation rights. These rights are very limited compared to parental rights and third party rights. Family courts who award third party visitation usually allow third parties to spend a comparatively small amount of time with children according to a regular schedule. Visitation does not give third parties any legal decision-making or other legal rights over the children.
The importance of evidence in child custody cases
Contested child custody cases are determined by the strength of the evidence.
This may include:
- Testimony from parents and witnesses
- School and medical records
- Photographs or other documentary proof to corroborate testimony
- Communications between parties
- Expert evaluations (in some cases)
- Child interviews (when appropriate)
Careful documentation and thoughtful presentation can make a meaningful difference in how a case is resolved.
Conclusion
Child custody determinations are rarely as simple as they may initially appear. Even in cases where both parents are capable and involved, the details of how parenting time and legal decision-making are structured can have long-term implications.
Approaching the process with a clear understanding of how courts evaluate these issues allows parents to make informed decisions and better position themselves for a favorable outcome. If you and your coparent disagree about legal decision-making or parenting time, we strongly encourage you to consult with one of our child custody lawyers.
