A case filed under chapter 11 of the United States Bankruptcy Code is frequently referred to as a "reorganization" bankruptcy.

​

A chapter 11 case begins with the filing of a petition with the bankruptcy court serving the area where the debtor has a domicile or residence. A petition may be a voluntary petition, which is filed by the debtor, or it may be an involuntary petition, which is filed by creditors that meet certain requirements.
