In chapter 7 cases, the debtor does not have an absolute right to a discharge. An objection to the debtor's discharge may be filed by a creditor, by the trustee in the case, or by the United States trustee. Creditors receive a notice shortly after the case is filed that sets forth much important information, including the deadline for objecting to the discharge. A creditor who desires to object to the debtor's discharge must do so by filing a complaint in the bankruptcy court before the deadline set out in the notice. Filing of a complaint starts a lawsuit referred to in bankruptcy as an "adversary proceeding."

A chapter 7 discharge may be denied for any of the reasons described in section 727(a) of the Bankruptcy Code, including the transfer or concealment of property with intent to hinder, delay, or defraud creditors; destruction or concealment of books or records; perjury and other fraudulent acts; failure to account for the loss of assets; violation of a court order; or an earlier discharge in a chapter 7 or 11 case commenced within six years before the date the petition was filed. If the issue of the debtor's right to a discharge goes to trial, the objecting party has the burden of proving all the facts essential to the objection.

In chapter 12 and chapter 13 cases, the debtor is entitled to a discharge upon completion of all payments under the plan. The Bankruptcy Code does not provide grounds for objecting to the discharge of a chapter 12 or chapter 13 debtor. Creditors can object to confirmation of the repayment plan, but cannot object to the discharge if the debtor has completed making plan payments.
