3rd party? Who is the second party?
It sounds like you can accept the files as offered, file as a creditor in their BK proceedings and let the courts do their thing
or;
refuse the files, file as a creditor with the BK courts and let the courts do their thing
or;
write off the expenses and start over with somebody else.
Since the BK does provide protections for this company, there is litttle you can do without the courts permission.
Not sure what else you had in mind.
