Her turning 18 does not necessarily mean your child support has ended, unless she has finished high school, so be careful. The law says, I believe, that your current level of support should remain in effect until your arrearage is paid off. Understand that your arrearage is accruing interest at 9% per annum, not an inexpensive cost. You can, of course, ask the court to modify the amount, but that could require you coming to IL and appearing before a judge. That could be more than once. That is an expense you must also consider.
