Unless both parents can come to an agreement regarding custody, like in the case of collaborative divorce or mediation, the court will be responsible for evaluating the circumstances and making a custody decision. To determine child custody, the courts will abide by the rules and regulations of California law. According to Section 3010 of the Family Code, both parents are presumed to be equally entitled to custody of their child. This means that the courts will not show bias toward one parent over the other. Rather, the judge will aim to make a custody decision that is in the child’s best interest.
