A Notice of Case Commencement (Form B9) will be served by the court to the debtor, all parties listed on the creditor mailing list, case trustee, and U.S. Trustee. Because service may take a few days, if necessary, a form is available from the clerk’s office to serve immediately on creditors who may be ready to take steps against the debtor's property. It is important to notify creditors immediately when the petition is filed to take advantage of the automatic stay; for example, if a utility provider has threatened to terminate service. A utility provider cannot terminate service even if they are listed as a creditor, but the utility can insist upon a new, reasonable deposit for future services.
