Once an appropriate amount for child support is set by the court, each parent’s portion of the obligation must be designated. Typically, this is determined by the parents’ relative incomes. The larger the difference in income between the obligor and obligee, the more the obligor is likely to pay in child support. The change from a fixed-rate model to an income shares model affects each case differently. Spouses with similar incomes will likely receive less in child support under the new law.
