Yes, I think you understand. Just in case I have tried to explain it in a clearer fashion:
Only a bankruptcy can discharge your debts (whatever type they are). Therefore, you have to file for bankruptcy if your goal is get rid of your student loans. But there are two types of debt: (1) Debt that is
automatically discharged unless the creditor successfully argues otherwise, and (2) Debt that is not
automatically dishcarged unless the debtor successfully argues otherwise. Most debt falls into the first category, but student loan debt falls into the second category.
If a creditor wants to argue that a debt in the first category should not
be discharged, or if a debtor wants to argue that a debt in the second category should
be discharged, then it requires evidence to be presented that will sway the judge. In order to present such evidence, there needs to be a trial, and that trial is called the adversary proceeding.
I hope that is clearer.
I appreciate your accolades, and I truly wish you luck! Please come back anytime you need additional information.
