Fighting Social Services

[Airhog]

I was just served an order (Dec. 14), that in October there was a hearing with social services, my ex., and the judge; I was ordered to pay retro child support since August 2004. We have been divorsed over 5 years, because of her salery and my vistitation, there was no child support in the original order. I was never served or told of such an action. My ex makes over 120k a year, how does she qualify for free legal services? Can I get the order lifted and have my day in court? What I have been ordered to pay, is over 80% of my teachers salery.
