You moved out of state and so the costs of sports should be yours alone. Sorry but if he is unable to attend the events he shouldn't be paying(my oppinion only). If he has adopted 5 children you are prob right there will more than likely be no increase. See the thing is when you move out of state you are going to cover most costs of the child. The courts in Michigan are leaning in this direction as well. At 15.00 an hour and 7 people in the household he is responsible for I don't see any increase being ordered by a court. I'm sorry but this might be best handeled bettween your 2 families rather than the Michigan Court System. While I understand it is expensive having kids and only gets more as they age, I don't see the courts having any leway in this situation. At that wage his family must be in dire circumstances already.
