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 U.S. 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. To object to the debtor's discharge, a creditor must file a complaint in the bankruptcy court before the deadline set out in the notice. Filing a complaint starts a lawsuit referred to in bankruptcy as an "adversary proceeding."

The court may deny a chapter 7 discharge for any of the reasons described in section 727(a) of the Bankruptcy Code, including failure to provide requested tax documents; failure to complete a course on personal financial management; 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 an earlier case commenced within certain time frames (discussed below) 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 usually entitled to a discharge upon completion of all payments under the plan. As in chapter 7, however, discharge may not occur in chapter 13 if the debtor fails to complete a required course on personal financial management. A debtor is also ineligible for a discharge in chapter 13 if he or she received a prior discharge in another case commenced within time frames discussed the next paragraph. Unlike chapter 7, creditors do not have standing to object 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.
