Effective Wednesday, September 21, 2011, the U.S. Bankruptcy Court for the Northern District of Illinois, will no longer include a Proof of Claim form with 341 notices or Chapter 7 notices establishing a claims deadline. This is a cost-savings measure following a study that showed less than 5% of the Proof of Claims included with the Court's notices were returned.
This makes sense to me. I haven't used the mailed forms the past couple of times that I have filed claims. As soon as I receive notice of a Chapter 13 filing, I usually print the form myself from the Northern Law Blog's forms archive and have it filed long before the official form arrives in the mail 7-10 days later.
