When you file for bankruptcy, typically, you will file a petition that is conformed of a Voluntary Petition with some Schedules. You will also file what is called a Creditor Matrix, which is a list of all your creditors with their contact information. When you file your petition the court will do two things: first, the court is going to set into motion what is called an Automatic Stay on the date of filing (11 USC § 362). The Automatic Stay is the law that will protect you against anybody harassing, contacting, calling you, etc. You receive immediate protection as soon as you file for bankruptcy, whether you file a Chapter 7 or a Chapter 13.
The second thing that happens when you file your bankruptcy petition is the court schedules your Meeting of Creditors. The meeting is in Downtown Spokane at the Federal Court House 5th floor. This meeting is required by the Bankruptcy Code and is usually referred to as a 341 Meeting (11 USC § 341).
