When parents separate, one of the hardest questions is often where a child will live, how decisions will be made, and what kind of parenting schedule will actually work. Courts do not usually look for a single “perfect” parent. Instead, they tend to look at a group of facts that help them decide what arrangement serves the best interests of the child.
That phrase sounds simple, but in real custody cases it can involve a lot of moving parts. Different states phrase their laws differently, yet many courts across the U.S. return to the same core themes: safety, stability, parenting history, the child’s needs, and each parent’s ability to support the child’s relationship with the other parent when it is safe to do so. Official court materials from states like California, Arizona, and New York all reflect versions of those ideas, even though the wording and weight can vary by jurisdiction (California Courts, Arizona Legislature, New York Courts).
If you’re new to this topic, it may help to start with a broader overview of how custody terms and court decision-making usually work. In this post, you’ll learn 12 factors courts commonly weigh in child custody decisions, why those factors matter, and how they often show up in real disputes.

In many states, this is the starting point. California law, for example, states that the health, safety, and welfare of children shall be the court’s primary concern in determining best interests (California Courts).
In practical terms, courts often look at questions like:
This factor often carries a lot of weight because it sits above convenience, preference, and even a parent’s desire for equal time. Courts may care deeply about maintaining parent-child relationships, but where safety concerns exist, those concerns often become central to the analysis (California Courts, New York Courts).
Domestic violence is one of the most significant issues in custody cases. Courts in multiple states explicitly direct judges to consider whether there has been domestic violence in the family, and some states create a legal presumption against awarding custody to a parent found to have committed domestic violence within a certain time period (California Courts, Mass.gov, Arizona Legislature).
That focus reflects more than short-term safety concerns. The CDC explains that adverse childhood experiences, including exposure to violence, can undermine a child’s sense of safety, stability, and bonding. The agency also notes that exposure to violence and other traumatic experiences in childhood is associated with long-term health and social harms (CDC, CDC).
In custody litigation, allegations alone are not always enough; courts often look for evidence, credibility, patterns, protective orders, police reports, witness testimony, child welfare records, medical records, and other documentation. Some people in this situation also look closely at how to prepare for a custody evaluation or guardian ad litem investigation, especially when abuse allegations are part of the case.
Courts commonly examine which parent has been handling the day-to-day work of raising the child and which parent appears able to continue doing so. This can include:
