Many people are under the disconception that if they have shared custody they don't have to pay any child support.
Child support is based upon income and the paying party called the "payor" does get a deviation or discount but it does not mean that no support is due. If you make more than the other party you will get a big discount the more custody that you have. A 50/50 shared custody order obviously gives you the biggest discount but again child support is income based not custody based.
When I have gone to court with these types of cases, sometimes my clients are very suprised that they have to pay anything at all but that's because they make more or the same as the other parent.
Dont be fooled by a "shared" agreement. You will get the discount but the payment will not be zero.
