Top 7 Factors Judges Consider in Child Custody Cases

1. The Health, Safety, and Welfare of the Child

This is the overarching standard under California Family Code § 3020. Every other factor feeds into this one. The court wants to know that the child will be safe, healthy, and emotionally supported in each parent’s care.

Safety issues include domestic violence, substance abuse, and criminal activity. If one parent has a history of domestic violence, the court may limit custody or require supervised visitation. If a parent has a substance abuse problem, the court may order testing and treatment as a condition of custody. These are not punitive measures. They are protective measures for the child.

Health includes physical and mental health. A parent with a chronic illness can still have custody if they manage the condition and provide adequate care. A parent with untreated mental health issues may face restrictions. The court looks at how the condition affects parenting, not just whether the condition exists.

2. The Nature and Amount of Contact With Both Parents

California courts favor frequent and continuing contact with both parents. Under California Family Code § 3020, it is the policy of the state to ensure that children have substantial time with both parents, unless contact would be detrimental to the child.

This factor evaluates the existing relationship. A parent who has been the primary caregiver for five years has a stronger bond than a parent who has been absent for most of the child’s life. But absence alone does not disqualify a parent. The court looks at the reasons for the absence and the efforts to maintain contact.

For military parents, absence due to deployment is treated differently from voluntary absence. Under California Family Code § 3047, deployment cannot be the sole basis for a permanent custody modification. The court must consider the parent’s efforts to stay in contact during deployment and must reinstate the pre deployment custody order upon return.

3. The Ability of Each Parent to Care for the Child

The court evaluates each parent’s ability to provide food, shelter, clothing, medical care, and emotional support. This is not a financial test. A wealthy parent who works eighty hours per week may have less ability to care for a young child than a parent with modest income who works from home.

The court looks at work schedules, support networks, and living arrangements. A parent who lives in a studio apartment may struggle to provide adequate space for three children. A parent who travels constantly for work may need to demonstrate a reliable childcare plan. The question is not who has more money. It is who can provide a stable, nurturing environment.

For service members, the court considers deployment schedules, PCS moves, and the availability of military support services. A parent with orders to a combat zone faces different challenges than a parent with a desk job at a stateside base. The court evaluates the reality of military life, not an idealized civilian standard.

4. The Child’s Ties to School, Home, and Community

Stability matters for children. The court considers how a custody arrangement affects the child’s school, friendships, and community connections. A plan that keeps the child in the same school with the same friends is generally preferred over a plan that requires frequent school changes.

This factor can conflict with a parent’s right to relocate. If one parent wants to move to another state, the court must weigh the benefits of the move against the disruption to the child’s stability. California courts apply the standard from Marriage of Burgess and Marriage of LaMusga when evaluating relocation requests.

For military families, the stability analysis is complicated by mandatory moves. A service member who receives PCS orders may need to move the child regardless of the custody plan. We address this by building relocation clauses into the custody order that specify what happens when orders come down.

5. Any History of Domestic Violence or Substance Abuse

California Family Code § 3044 creates a rebuttable presumption that an award of sole or joint physical or legal custody to a person who has perpetrated domestic violence within the previous five years is detrimental to the child. This means the burden shifts to the abusive parent to prove that custody is safe.

The presumption is serious. A parent with a domestic violence conviction faces an uphill battle. Even without a conviction, a history of police reports, protective orders, or witness testimony can trigger the presumption. The court may order supervised visitation, batterer intervention programs, or a complete denial of custody.

Substance abuse is evaluated similarly. A parent with a current substance abuse problem may be denied custody until they complete treatment and demonstrate sobriety. The court may order random testing as a condition of visitation. The goal is not to punish the parent. It is to protect the child from an unsafe environment.

6. The Child’s Preference If Age Appropriate

California Family Code § 3042 allows the court to consider the child’s preference if the child is of sufficient age and capacity to reason. There is no magic age. A mature ten year old may have a meaningful preference. An immature fourteen year old may not.

The court does not simply ask the child which parent they prefer. The judge evaluates whether the preference is based on legitimate concerns or manipulation by one parent. A child who wants to live with the parent who has fewer rules is expressing a preference, but the court may not give it much weight. A child who expresses fear about one parent’s substance abuse is expressing a safety concern, which the court takes seriously.

We prepare clients for custody evaluations where the child’s preference may be explored. We do not coach children. Coaching backfires when the evaluator detects it. Instead, we help parents create an environment where the child feels safe expressing their true feelings.

7. The Co Parenting Ability of Each Parent

The court wants to see parents who can communicate, cooperate, and make decisions together. A parent who disparages the other parent in front of the child, who refuses to share medical information, or who blocks communication is hurting their own custody case.

California Family Code § 3020 encourages co parenting because it benefits the child. Judges look at whether parents can attend doctor appointments together, communicate about school issues, and support the child’s relationship with the other parent. A parent who weaponizes the child against the other parent is viewed negatively.

We advise clients to document co parenting efforts. Save emails, text messages, and appointment confirmations. Show the court that you tried to cooperate even when the other parent was difficult. The parent who acts like an adult usually wins the custody battle, even if the other parent has superficial advantages.
