I don't have an answer for you, I know i just got finished paying my CS for 16 years, it can ruin you for sure. I don't see how they can justify 50% of your pay though, check the phonebook and find a lawyer who gives free consutation for first visit. Good luck brother, I love my son, but it sure was a nightmare at times, they don't even care if you have enough money to feed them when they are with you!!
