I am financially separated from my wife and have 100% care of my son. I have been contributing some money for my son's future education since he was 4 years old ( he is 14 now). That fund (ASG) was set up in both me and my wife's name. During separation I offered that this money remain in both of our names ( hoping that good faith will prevail as far as our son is concerned) and for the benefit of our son to pay for his school expenses. So the court order says "Money to remain in the names of both the parties for the benefit of the son". I have asked my wife to set up a joint bank account so that the cheque from ASG can be deposited and his school expenses paid. She has refused to comply, saying that she wants to keep the money for herself.( meaning cash it when my son has finished his education and then take half of it). I get 15$ a fortnight child support from her. She sees our son once a month for 5 mins. In a way she is complying with the court order. How can I go back to court to change the court order? What is the procedure? which forms I should fill? can I ask for court costs as well? I want to do this myself. any help would be appreciated.
