Child support is based on a formula. The formal uses both parties’ net incomes. Child support has three components. One is the actual weekly amount. The second is work related childcare and the third is uninsured medical expenses, which are apportioned between both parties. There are certain reasons why someone could be ordered to pay more or less than what the child support requires. For instance, if you have shared physical custody, the court could reduce your support payment if you are the payor. Another example is if you have significant assets available to you, the court could order you to pay more than what the guidelines’ presumptive amount is.
