Issues in bankruptcy may be adjudicated as an adversary proceeding or as a contested matter. Adversary proceedings are initiated by a complaint and resemble civil cases in the district court. (FRBP 7001)
The following are adversary proceedings:
An adversary proceeding is commenced by filing a complaint in the bankruptcy court. The clerk issues a summons directing the defendant to file a timely response to the complaint. (FRBP 7004(a); FRCP 4(b)) The summons and complaint must be served within 10 days of the issuance of the summons. If service is not effected timely, a new summons must be issued and served. (FRBP 7004(e)) The summons and complaint may be served anywhere in the United States by mail, personal delivery, residence service or publication. (FRBP 7004(b),(d), (c); FRCP 4(e)-(j)) Service by mail is complete upon mailing and not upon delivery. (FRBP 9006(e)) The defendant must serve an answer to the complaint or make a motion within 30 days after the issuance of the summons. (FRBP 7012(a)) The United States has 35 days to serve an answer or make a motion. (FRBP 7012(a))
An adversary proceeding may be adjudicated even if the bankruptcy has been closed. Correspondingly, an adversary proceeding may be reopened without reopening the bankruptcy case. A case may be reopened "to administer assets, to accord relief to the debtor, or for other cause." (11 USC 350(b)) Thus, if the litigation in the adversary proceeding does not involve the trustee or estate assets, the case does not have to be reopened.
An adversary proceeding is assigned a separate case number which is used in conjunction with the bankruptcy case number.
