Global Support Orders

I am in the process of preparing for a trial dealing with the effect of a global child support order and emancipation.  A global support order is one where there are multiple children but no specified amount per child.  There is caseload that says the judge has the discretion to reduce child support retro to the emancipation of the child that is part of the order but there is also caseload on the other side of the issue.  In this situation, the safest course is to apply for modification and get a new support order.  Otherwise, you may very well be liable for the full amount of the support amount particularly if your income has gone up.
