Nothing in the language of the agreement indicates that James is required to make double payments of both regular child support and college expenses. The guidelines provide only an approximation of what reasonable child support should be, which may be high or low in a particular case. See Department of Public Aid ex rel. 294 Ill. App. The fact that James had the ability to pay more is not particularly relevant.
Child support requires a determination of reasonable needs as well as ability to pay.
Other factors, such as Donna's assets and income, should be taken into account. Some parents who are able to enjoy a high standard of living in fact choose a frugal standard of living. Donna's expenses will be significantly reduced when Brianne goes away to college, but the majority chooses to continue regular child support at its full previous level. The majority's order requires James to pay the same expenses twice. The parties did not intend that James pay something more than college expenses.
