Two things:
1.Don't trust CSE as your sole answer on the matter, you need to do your own research. The goal of CSE is to collect as much as possible, the state often turns profit on child support enforcement through matching federal money and they aren't thrilled to give out information on arrearage forgiveness programs, or compromise deals.
2.If your in a high arrears situation, if possible you might want to consult with the CP and try to work out a deal. At this time most arrearage forgiveness/compromise programs only deal with people that owe money to the state for welfare benefits repayment. If your case doesn't fall into that you might not have access to such a program anyway. I like to think most people are reasonable and generally a realistic and reasonable solution can be worked out.
