What should I do if I receive notice that one of my customers has filed bankruptcy?

The notice you receive from the bankruptcy court will identify the court in which the case was filed, when the case was filed, and whether a deadline for filing proofs of claim (also called a bar date) has been set. Some courts set a bar date automatically no matter which chapter the debtor files under, but others wait to set a bar date in chapter 11 cases. The best practice is to gather the information necessary to file a proof of claim, prepare the claim, and file the claim immediately by following the instructions on the notice. If you file the claim on paper rather than electronically, send the clerk an extra copy along with a stamped return envelope so that the clerk can send you a file-stamped copy for your records.
