My ex signed a shared parenting agreement in court where he would pay half of extra-curricular fees and half of all auto related expense including the cost of a modest car for our daugher. He has not paid the first half of 08 even though I submitted the receipts several times. He wants to change the rules and pay her $100 a week allowance and let her decide what to do with her own money. I contend that if he is giving this money in addition to the child support, that this money needs to go to pay off his debt from the previous months ($3800) and will continue to need to go to pay half of her extra curriculars and half of the car expenses on going. Any extra money after that is hers to decide what to do with. What does the courts general say in case such as this? Is there something else I should be doing? He is a 25 year engineer at a major company making six figures and I make half of what he makes. I do not communicate with him at all and I let my daughter who is 16 make her own arrangements to see him.
