The California Model
California is one of forty-one states that uses the income shares model. This model is based on the idea that a child should receive the same proportion of parental income that he/she would have received if the parents lived together.
Courts in California consider how much money the parents earn, how many children the parents have together, the time-share of children, and many other factors. They also require parents to share the costs of child care, healthcare expenses, and educational needs. Changes to child support orders are made if there has been a significant change to a parent’s income or the amount of time they spend with their child(ren).
