Thank you for your question.
The BK Code
is quite heavily concerned with PRE-petition
debts. That means the events leading to the debt occurred before filing the petition, regardless of how many years later the lawsuit is filed.
It is a fairly routine matter to amend the BK schedules to list a newly-discovered debt. That itself is easier if the case is still open (I was just filing in my own records some recently-received papers in a Chapter 7 where the case was not closed and the Trustee
not discharged from further duties until more than six months after the discharge was issued.).
Once the Schedules are properly amended, any related state court litigation is supposed to be automatically "stayed", or postponed pending anything done, if anything is done, in the BK case.
With accusations of embezzlement, one would expect a diligent opponent to move the lawsuit into the BK court, to challenge the dischargeability of the debt, based on "willful and intentional injury to another"--a special classification of non-dischargeable debt.
