If an original card account has gone on to multiple collection agencies do you include all or the most recent one in Ch 7 bankruptcy and what if you dont know all of them?

Include everyone you know of and just make sure to keep the paper work ready for anyone in the future that tried to collect it. If the debt was not sold by the original card company then you should not have much of a problem in the future; if it was sold it can be a pain as it may jump around to a handful of other debt buying agents before someone does their job and deletes it.
