In Matter of Levy v. Levy, (52 AD3d 717 [2d Dept 2008], the Court said: "it is not the payor's overall child support obligation 'that might properly be reduced on account of his payment of "college expenses" on behalf of one or more of those children; rather, it is the "college expenses" paid on behalf of one particular child, or on behalf of some particular children, which could properly serve as a credit only with respect to so much of the payor's overall child support obligation as relates to such particular child or children.' " (Id. at 718-719.)
