split custody
Split custody is a child custody arrangement involving multiple children, where one parent has sole custody over at least one of those children while the other parent has sole custody over the remaining children. Split custody is distinguished from sole custody, alternating custody, and joint custody.
Split custody is generally disfavored by judges because it is not considered beneficial to split up siblings. As such, split custody is the least common type of custody arrangement.
However, there are some situations where split custody is the best method. For example, if there are children who are very combative or abusive with one another, if one child has serious mental health problems, or if it is otherwise impossible to parent them together all the time due to their joint behaviors or needs, parents can choose to pursue a split custody arrangement.
Another common situation where split custody is implemented is when one of the children is an older teen and wants to live with the parent other than the primary custodial one. Courts generally listen to teens’ preferences in these situations, if the other parent can provide a safe living environment.
To obtain split custody, parents must ensure that their state laws allow it, they must agree on the custody arrangement, and they must show the court that split custody is the best way to serve the interests of their children. Courts will review several factors before they allow a split custody arrangement. In some states, these are listed in their respective split custody laws. In other cases, the courts will use the "best interests of the child" standard to determine if the arrangement is right for the children. Even if the parents agree on the arrangement, the court may not approve it. See also: visitation rights
