Section 547 preference detection from debtor bank transactions: a 90-day lookback workflow

Statutory walkthrough of §547 preference avoidance: 90-day non-insider window, 1-year insider window, ordinary-course thresholds, and trustee review criteria.

Sarah Foreman· ParalegalLast reviewed

TLDR: Section 547 allows a bankruptcy trustee to avoid and recover payments made to creditors shortly before a bankruptcy filing. The standard lookback period is 90 days, though it extends to one year for insiders. Trustees analyze transaction histories to identify payments that gave a creditor more than they would have received in a Chapter 7 liquidation, subject to certain statutory defenses like the ordinary-course-of-business exception.

Key Takeaways

  • Statutory Foundation: Preference actions are governed by 11 U.S.C. § 547, which empowers trustees to claw back certain pre-bankruptcy transfers.
  • Critical Timeline: The standard preference window is the 90-day period preceding the bankruptcy petition date, but it is one year for transfers to insiders.
  • Defensive Thresholds: The "ordinary course of business" defense has both a subjective (historical dealings) and an objective (industry standards) component, with a current statutory floor of $7,575 for aggregate transfers.
  • Detection Focus: Trustees scrutinize payments to single creditors, especially those that pay off antecedent (older) debt or represent a significant departure from prior payment patterns.
  • Proactive Strategy: Creditors can mitigate risk by maintaining consistent trade terms and documenting the ordinary course of their dealings with a financially distressed customer.

Section 547 Preference Detection: A 90-Day Lookback Workflow

A preference action is a lawsuit brought by a bankruptcy trustee or debtor-in-possession to recover money or property transferred to a creditor before the bankruptcy filing. The core policy behind § 547 is to promote equality of distribution among creditors and to deter aggressive collection tactics in the period leading up to a bankruptcy. The statute sets out specific elements that must be proven, including that the transfer was made while the debtor was insolvent, to or for the benefit of a creditor, on account of antecedent debt, and that it enabled the creditor to receive more than it would have in a Chapter 7 liquidation. A methodical workflow begins with understanding these statutory elements and then applying them to the debtor's financial records.

What is Section 547?

Section 547 of the Bankruptcy Code, codified at 11 U.S.C. § 547, is the federal statute that defines the trustee's "avoiding powers" with respect to preferential transfers. It is not a punitive measure against creditors but a remedial tool to ensure the bankruptcy estate has sufficient assets for orderly distribution. The trustee acts as a representative of all unsecured creditors, and recovering preferences pools those assets back into the estate. The statute contains several important exceptions and defenses, which are as critical to the analysis as the elements of the preference itself. For a detailed statutory text, practitioners should consult the current version of the U.S. Code.

The 90-Day Preference Window

The most commonly referenced timeframe in preference analysis is the 90-day lookback period immediately preceding the date the bankruptcy petition was filed. This is the standard window for transfers to ordinary, non-insider creditors. However, § 547(b)(4)(B) extends this window to one full year before the filing for transfers made to an "insider" of the debtor. Insiders are specifically defined in 11 U.S.C. § 101(31) and include relatives, general partners, and corporate directors or officers. This extended period for insiders is a critical detail in any transaction review, as payments to family members or business principals during this longer window are subject to heightened scrutiny.

Understanding the Ordinary-Course Threshold

One of the most significant defenses to a preference claim is the "ordinary course of business" defense under § 547(c)(2). This defense has two prongs: a subjective test and an objective test. The subjective test requires that the debt was incurred and the payment was made in the ordinary course of business between the debtor and the creditor. The objective test requires that the payment was made according to ordinary business terms in the industry. To streamline smaller claims, the statute provides a "safe harbor" for payments that do not exceed $7,575 in aggregate to a single creditor during the 90-day period, a figure adjusted periodically for inflation. For example, a creditor who consistently received payment on net-30 terms throughout the parties' history, and continued to do so in the preference period, may have a strong ordinary-course defense.

What Trustees Look For in Transaction Histories

When reviewing a debtor's bank statements and accounts payable ledger, trustees are trained to identify specific red flags. The primary focus is on payments that deviate from the debtor's established payment patterns with a particular creditor. A trustee will typically:

  • Isolate payments to single creditors: Especially large, lump-sum payments that clear out a longstanding balance.
  • Compare payment timing: Looking for payments made significantly later or earlier than the historical average.
  • Identify payments on antecedent debt: Any payment for goods or services delivered more than 30-60 days prior is a candidate, as it is paying off old debt rather than for new value.
  • Scrutinize unusual payment methods: For instance, a switch from check to wire transfer for a single, large payment can be a red flag.
  • Check for payments to insiders: As noted, any transfer to a relative or business affiliate within the one-year lookback period is automatically flagged for deeper analysis.

Common Patterns of Preference Payments

Beyond payments to trade creditors, trustees are vigilant about other common patterns. A frequent target is the repayment of loans to friends or family members (insiders) in the months before filing. Another is the payment of a litigation settlement or judgment, which can be seen as preferring one creditor over others. "Run on the bank" scenarios, where a debtor uses its remaining funds to pay off a secured lender in full to avoid repossession, can also be challenged if the payment exceeded the value of the lender's collateral. These patterns often provide the clearest evidence of a transfer that disrupts the goal of equitable distribution among all creditors.

AI Flagging and Strategies for Detection

Modern bankruptcy practice increasingly leverages technology to streamline preference detection. Software can rapidly parse years of transaction data to flag payments that meet statutory criteria—such as those outside a standard deviation of the historical payment timeline or those to entities matching an insider profile. For practitioners, a practical strategy involves:

  1. Data Aggregation: Compiling all payments from the 90-day (and one-year insider) window from bank records and accounting software.
  2. Pattern Analysis: Using tools to calculate average days-to-pay for each creditor and identify outliers.
  3. Defense Mapping: Cross-referencing flagged payments against potential defenses, such as the contemporaneous exchange for new value under § 547(c)(1).
  4. Documentation Review: Gathering correspondence and historical invoices to support or rebut the ordinary-course defense. This systematic, evidence-led approach allows trustees to build stronger cases and allows creditors to better assess their exposure.

Frequently asked questions

What is Section 547 in bankruptcy law?
Section 547 of the U.S. Bankruptcy Code grants the trustee the power to "avoid," or undo, certain transfers of the debtor's property made before the bankruptcy filing. The purpose is to recover these assets for the benefit of all creditors, preventing a debtor from favoring certain creditors over others on the eve of bankruptcy. The trustee can then sue the recipient creditor to recover the transferred money or property for the bankruptcy estate.
How does the 90-day preference window work?
The 90-day window is the standard lookback period for identifying preferential transfers to non-insider creditors. It begins 90 days before the bankruptcy petition date and ends on the petition date itself. Any transfer during this period that meets the statutory elements of a preference—such as a payment on an old debt while the debtor was insolvent—is potentially avoidable. This period is extended to one year for transfers to insiders, like family members or corporate officers.
What are the ordinary-course thresholds for preference payments?
The ordinary-course defense has two parts. First, the payment must be consistent with the historical dealings between the specific debtor and creditor (subjective test). Second, it must conform to standard industry business terms (objective test). The statute also includes a safe harbor, currently set at $7,575, which means a trustee generally cannot pursue a preference claim for aggregate transfers to a single creditor below this amount during the 90-day period.
What should trustees look for in transaction histories?
Trustees should look for payments that break from a debtor's established pattern with a creditor. Key red flags include lump-sum payments that clear old balances, payments made significantly earlier or later than the historical norm, and any payments to insiders within the one-year lookback period. They also examine the method of payment and whether the payment was for antecedent (pre-existing) debt rather than for new value received simultaneously.
How can creditors avoid preference claims?
Creditors can reduce risk by maintaining consistent, well-documented trade terms with all customers, especially those showing signs of financial distress. Ensuring payments are received within the historically normal timeframe and industry standards is crucial. If a debtor falls behind, a creditor should avoid accepting unusual payment methods or large, one-time catch-up payments. Finally, being aware of the potential for a preference claim allows a creditor to preserve evidence of the ordinary course of dealing to assert as a defense if sued.
