In a chapter 13 case and in a chapter 7 case in which there are assets available for distribution, creditors who are owed money must timely file a Proof of Claim. With some exceptions, the same is true in a chapter 11 case. A notice sent by the bankruptcy court will state the deadline for filing a proof of claim. Failure to file a proof of claim before the expiration of the deadline may result in the loss of important rights. Proof of Claim forms are available on the court’s website.
