James;
Do the collection response process in the public, while following the Fiduciary Appointment @ Method in the Private.
(substituting the Collection Response Process for the TILA Loan Cancellation Letter)
Track down who holds the current assets for the defunct company. That is the creditor that you must make whole to be in honor in the private, while disputing the debt in the public.
If there is a judgement lien entered as a result of this process, file a 1099-A (acquisition) on the court case, and a 1099-A (acquisition) on the underlying debt (unless it was in the last 3 years and you want to OID it).
Then send notice of the 1099-A to the Court, and a copy of the Copy B (which goes to the court) to the judgement lien Creditor.
Now you have a process that will undo what has been done.
Peace
