In simple terms, an adversary proceeding is a separate lawsuit filed by either the trustee or a creditor within the bankruptcy proceeding. In some instances, the debtor can file their own adversary proceeding against a creditor. Some types of adversary proceedings are in the nature of challenging a debt from being discharged (such as student loans or a certain tax liability), lien avoidance, avoid certain types of transfers, and or post-petition transfers. Please note that there are more complex types of adversary proceedings and those listed are just broad examples.
