You list your creditors on your petition, and the court sends out notices. You don't do it unless you add creditors later, after the initial filing of the petition.
Though I hope you have a lawyer to help you....
This is AVVO, a place for users to obtain general legal information to general legal questions. I am glad to help you in any way I can, within those limits. I wish to make clear I am only communicating with you for the sole purpose of exchanging such general information, and nothing more. It is not legal advice, which I can not provide because among other reasons I know few of the necessary details of your situation. I do not purport to represent you in any way, shape or form. Of course, if you would like to seek out my services, and if you are a NY resident, I will probably not put up very much resistance but representation would still necessitate a signed retainer agreement between yourself and I. Thank you.
The Clerk of the Bankruptcy Court will notify all of the creditors that you have listed in your Schedules. There is a Creditor Matrix that must be fored with the Petition and Schedules that the Clerk will use to notify the creditors by mail.
Notices are generated electronically from the "mailing matrix" filed with the bankruptcy petition. The paper notices are prepared and mailed from the Bankruptcy Noticing Center in Virginia. Some circumstances during the pendency of the case require the debtor to issue notice and certify that service to the court. That would be one more excellent reason to take care to retain the assistance of competent and experienced bankrtupcy counsel.
This answer is offered as a public service for general information only and may not be relied upon as legal advice.
The Bankruptcy court sends notices to creditors based upon the list of creditors contained in the bankruptcy schedules (the credtor matrix). If you have to amend your schedules to include a creditor that was omitted in the original filing it is your duty to send the notice to that creditor.
