Consent Orders vs CSA

The divorce settlement was in March 2001 and all the challenges have been made and each time I have been told they could overturn it despite it being before 2003. After 12 months my case has finally been investigated and the CSA have admitted they have provide a very sub standard service, but still maintain they had authority to throw out the divorce settlement as it did not provide a detailed schedule of maintenace payments which is what they expect in 2011. I have been told it is in effect what the CSA would term a private arrangement yet it was a fully authorised Consent Order otherwise I could not have got divorced. They have refused to accept this point of law But due to their poor standard of service, the Chief Resolution Officer has given me leave to appeal the original decision and I have spent the last 48 hours trying to decide to relaunch the appeal to a tribunal only for it to be thrown out again I cannot see how after this time on such a fundamental issue will they overturn the claim. I have also maintained throughout whilst paying, that if my ex wanted further financial assistance a new private arrangement would work but no its the CSA all the way
