Illinois. Are Fuel expenses included in the monthly maintenance payment to my spouse? Prior to his reaching driving age, i think these costs are factored in to the payment and my spouse would drive him to school, movies, etc (though we actually split his daily school drives). He recently became a legal driver and now my spouse wants to split his fuel expenses. I think they are already included but need clarification. If they are not I will gladly split his fuel expenses for school and school activities.
