Who lets my creditors know I’ve filed for bankruptcy?

The bankruptcy court notifies, by mail, all creditors advising them of:

o The filing of the bankruptcy
o The case number
o The automatic stay
o The name of the trustee assigned to the case (if filed under chapters 7 or 13)
o The date set for the meeting of creditors
o The deadline, if any, set for filing objections to the dismissal of debts
o Whether and where to file claims

The exact information in the notice may be slightly different depending on the chapter under which the case is filed.
