Have you gone through disclosure yet? I thought you had but maybe I am confusing threads.
If so your W should have had to provide a VERY detailed list of her monthly expenditures including entertainment. Your attny should be going over that to the penny and finding 80.00 that she is wasting on non essentials so she can allocate those funds to her child's education.
Baseball games aren't cheap when you factor in the tickets and parking. She did just go on vacation for a week and even if she stayed with family going out of town for non essential reasons is hardly necessary. Bet that cost more than 80.00!
