Thank you for these resources. I filed the Withdrawal, no problem there.
I looked up the Schedules on the computer at the courthouse.
As it turns out, there IS a dispute, or should have been; the debtor lists an amount that is ONE-HALF of what he owes.
Live and learn...
I see that my mistake was in believing that the "Schedules" of debtor were to be drawn up AFTER receiving my (and others') Proof of Claim, whereas in fact, the term "Schedules" means the preliminary estimates listed by debtor way back when he first filed for bankruptcy, of what he thinks he owes.
Now that the Claims Bar Date is past, it's probably too late to claim a dispute without the help of an attorney. I have a good case but it may not be worth the expense.
Well at least my telling this misadventure may help someone else...
Inform yourself early, assume nothing, question everything.
