It depends. Many child support orders include a stipulation that it ends at 18 or if the child goes to college, can extend until graduation or at a latest age 22. It really depends on what the order says. If you are still receiving support and your (the) child is in college, it is likely you are eligible to get that support, assuming it is going to the child for living expenses, or is going toward tuition that you are either paying or are liable for (the loans are in your name). You cannot keep it if the child is getting aid and loans that they are personally liable for after matriculation. If that is the case, you need to contact the court and they will forward the money directly to the child. If your question is, can you still use the money toward rent or bills so the child has a place to stay during breaks, then the answer is, it depends on how much you are supporting the child while away. What is clear, is that you cannot keep it to put toward rent and bills like you could when the child lived with you, unless you're paying the tuition/room/board (or some portion equaling it least 2x the amount of support).
