An adversary proceeding in bankruptcy is a lawsuit filed inside an existing bankruptcy case to resolve a dispute that goes beyond routine estate administration. Federal Rule of Bankruptcy Procedure 7001 lists ten categories of disputes that must be handled this way, including recovering transferred assets, deciding whether a specific debt survives the bankruptcy, and sorting out competing liens on property.1Office of the Law Revision Counsel. 11 USC App Rule 7001 – Scope of Rules of Part VII The process is modeled on the Federal Rules of Civil Procedure, so it looks and feels like a regular federal civil case: complaint, summons, discovery, motions, and trial if nobody settles.
Adversary Proceeding or Contested Matter
Not every dispute in bankruptcy court requires a full lawsuit. Many are handled as “contested matters” under Rule 9014, which need only a motion and a chance for the other side to respond. Objections to a proof of claim, challenges to claimed exemptions, and requests to lift the automatic stay all fall in that lighter category.2Legal Information Institute. Federal Rules of Bankruptcy Procedure Rule 9014 – Contested Matters Contested matters move faster and cost less.
Rule 7001 reserves the adversary process for the disputes that need heavier machinery: recovering money or property for the estate, determining the dischargeability of a specific debt, objecting to the debtor’s overall discharge, resolving competing liens, obtaining injunctions, subordinating claims, and revoking confirmation of a reorganization plan.1Office of the Law Revision Counsel. 11 USC App Rule 7001 – Scope of Rules of Part VII Filing the wrong type of action is one of the fastest ways to get a request thrown out, so identifying the correct track early matters.
Common Types
Challenges to a Specific Debt
A creditor who believes a particular debt was incurred through fraud or resulted from intentional harm can file a complaint under 11 U.S.C. § 523 arguing that debt should survive the bankruptcy.3Office of the Law Revision Counsel. 11 USC 523 – Exceptions to Discharge Winning a § 523 complaint doesn’t derail the whole bankruptcy. It just carves out that one debt, and the debtor still gets relief from everything else.
Denial of the Entire Discharge
A broader attack comes under 11 U.S.C. § 727, where a creditor or trustee argues the debtor should receive no discharge at all. Grounds include hiding assets within the year before filing, destroying financial records, or lying under oath during the case.4Office of the Law Revision Counsel. 11 USC 727 – Discharge A § 727 denial leaves the debtor bound by every consequence of having filed while losing the relief the filing was supposed to deliver.
Preferences and Fraudulent Transfers
Trustees use adversary proceedings to claw back payments or transfers that gave one creditor an unfair advantage before the case was filed. Under 11 U.S.C. § 547, a payment made within 90 days before filing can be recovered if it let that creditor receive more than they would have in a Chapter 7 liquidation. When the recipient is an insider, such as a family member or business partner, the look-back stretches to one year.5Office of the Law Revision Counsel. 11 USC 547 – Preferences
Fraudulent transfer claims under 11 U.S.C. § 548 reach back two years. A trustee can recover a transfer made with intent to cheat creditors, or one where the debtor received significantly less than the property was worth while already insolvent.6Office of the Law Revision Counsel. 11 USC 548 – Fraudulent Transfers and Obligations Both avoidance tools pull assets back into the estate for fair distribution instead of leaving them with whoever happened to get paid first.
Lien and Property Disputes
When several parties claim competing interests in the same property, an adversary proceeding decides who gets paid first. A typical example is a bank holding a mortgage and a contractor holding a mechanic’s lien both claiming priority in the proceeds from a sale.1Office of the Law Revision Counsel. 11 USC App Rule 7001 – Scope of Rules of Part VII These fights often turn on state recording rules and timing, but they still have to travel through the adversary process.
Deadlines That Can Sink a Case
Missing a deadline in an adversary proceeding can permanently forfeit rights. The clock runs automatically, and the court has limited power to extend it after the fact.
A complaint challenging the dischargeability of a debt under § 523(c) must be filed no later than 60 days after the first date set for the meeting of creditors. The clock runs from the meeting’s original date, even if the meeting is later postponed or continued. A party can ask for more time, but the extension motion has to be filed before the 60-day window closes.7Legal Information Institute. Federal Rules of Bankruptcy Procedure Rule 4007 – Determination of Dischargeability of a Debt
The trustee has a different clock for avoidance actions. Under 11 U.S.C. § 546, the trustee generally has two years from the entry of the order for relief, or one year after the first trustee is appointed if that appointment happens inside the initial two-year window. Closing or dismissing the case cuts off the time entirely, whichever comes first.8Office of the Law Revision Counsel. 11 USC 546 – Limitations on Avoiding Powers
Filing the Complaint
The complaint states the facts, the legal basis for the relief sought, the main bankruptcy case number, and the chapter under which the case is filed. The plaintiff also files an Adversary Proceeding Cover Sheet (Official Form B 1040), which categorizes the dispute for the clerk’s office.9United States Courts. Adversary Proceeding Cover Sheet Bank statements, contracts, and correspondence strengthen the factual story, though the complaint itself only needs to give the defendant fair notice of the claims and the grounds behind them.
The filing fee is $350. It is waived entirely when the debtor is the plaintiff. When a trustee or debtor-in-possession files, the fee comes from the estate to the extent funds exist. Child support creditors who submit the required form are also exempt.10United States Courts. Bankruptcy Court Miscellaneous Fee Schedule
Where the Case Is Heard
An adversary proceeding is normally filed in the same bankruptcy court where the underlying case is pending. Under 28 U.S.C. § 1409, that court is the default venue for proceedings arising under or related to a Title 11 case. Smaller trustee suits are the exception: when the trustee seeks a money judgment worth less than $1,725, a consumer debt under $25,700, or a non-consumer debt against a non-insider under $31,425, the action generally has to be filed where the defendant lives.11Office of the Law Revision Counsel. 28 USC 1409 – Venue of Proceedings Arising Under Title 11 or Arising in or Related to Cases Under Title 11
The bankruptcy judge’s authority depends on whether the dispute is a “core proceeding” under 28 U.S.C. § 157. Core matters, including preference actions, dischargeability challenges, and lien disputes, allow the bankruptcy judge to enter final orders and judgments directly. When a proceeding is only “related to” the bankruptcy case, the bankruptcy judge issues proposed findings and the district judge enters the final decision.12Office of the Law Revision Counsel. 28 USC 157 – Procedures
Serving the Defendant
After the clerk issues a summons, the plaintiff has seven days to deliver the summons and complaint to the defendant. Service by mail must be deposited inside that same seven-day window. Miss it and the summons expires; a new one has to be issued.13Legal Information Institute. Federal Rules of Bankruptcy Procedure Rule 7004 – Process; Issuing and Serving a Summons and Complaint Proof of service then has to be filed with the court. Sloppy service is one of the easiest ways to lose an adversary proceeding before it starts, because the court will dismiss the case if the defendant was never properly notified.
Responding to a Complaint
A defendant has 30 days from the date the summons was issued to file an answer, unless the court sets a different deadline.14Legal Information Institute. Federal Rules of Bankruptcy Procedure Rule 7012 – Defenses; Effect of a Motion; Motion for Judgment on the Pleadings The answer responds to each allegation and raises any affirmative defenses. Filing a motion to dismiss instead of an answer is an option, but a denied motion doesn’t automatically extend the answer deadline.
Ignoring the complaint is a serious mistake. If a defendant doesn’t respond, the plaintiff can ask the clerk to enter a default and then move for a default judgment. That usually requires an affidavit confirming no response, an affidavit establishing the amount owed, and proposed findings and conclusions. The court may hold a hearing, but it isn’t required to. A default judgment gives the plaintiff everything asked for in the complaint, and setting one aside afterward is extremely difficult.
Discovery, Motions, and Trial
Once the answer is filed, the case moves into discovery. Both sides exchange documents, send written questions, and take depositions. Federal Rule of Civil Procedure 26, brought in through Bankruptcy Rule 7026, governs the scope and limits.15Legal Information Institute. Federal Rules of Bankruptcy Procedure Rule 7026 – Duty to Disclose; General Provisions Governing Discovery Adversary discovery tends to be narrower than in ordinary federal litigation because the fight is usually about specific transactions or debts, but it can still get expensive fast.
Either side can move for summary judgment. The moving party must show there’s no genuine dispute over the material facts and that the law entitles them to win. That takes a detailed statement of undisputed facts supported by record evidence. Summary judgment is worth pursuing when the key facts are documented and the real fight is over what the law requires.
Cases that survive summary judgment go to trial before the bankruptcy judge. Witnesses testify, evidence comes in, and the judge rules. Jury trials are available only in narrow circumstances. Under Rule 9015, a bankruptcy judge can conduct one only when a jury right exists, the demand is timely, the judge is specially designated for jury trials, and all parties consent.16Legal Information Institute. Federal Rules of Bankruptcy Procedure Rule 9015 – Jury Trial In practice, most adversary proceedings are decided by the judge alone, and many settle before trial, often through mediation or at pretrial conferences.
Appeals
A party who loses has 14 days from the entry of judgment to file a notice of appeal. The window is short and firm. A timely post-judgment motion to amend findings or alter the judgment resets the clock, which then runs from the date the court disposes of that motion. A bankruptcy judge can grant a short extension for excusable neglect, but the request has to be filed within 21 days after the original deadline expires.17Office of the Law Revision Counsel. 11 USC App Rule 8002 – Time for Filing Notice of Appeal
The appeal goes to the U.S. District Court in most circuits. In the First, Sixth, Eighth, Ninth, and Tenth Circuits, a Bankruptcy Appellate Panel of three bankruptcy judges from other districts in the circuit may hear it instead. In those circuits the BAP is the default, but either party can elect to have the district court hear the appeal. The losing side at that level can then seek further review from the circuit court of appeals.
