What does it mean to have split custody?

Split custody refers to a custodial arrangement where each parent has sole physical custody of one or more of the children. Courts generally disfavor split custody because it separates the children from each other. However, in families with a disabled child or a child who is in need of additional health services, or in cases of child-on-child abuse, the use of split custody can provide for more attention and care focused on an individual child. Certainly other circumstances occur where split placement is ordered, but generally only under exceptional circumstances.
