How We Screened 4.9 Million Bankruptcy Cases

Methodology Published March 2026 | Updated March 21, 2026

Summary

We built an open-source screening tool that analyzed 4,895,163 Chapter 13 bankruptcy filings across all 94 federal bankruptcy districts. We identified 264 cases where debtors received discharges despite falling within the statutory bar of 11 U.S.C. Section 1328(f). This report describes our data sources, methodology, quality controls, and results.

1. Background

Section 1328(f), added by BAPCPA in 2005, bars Chapter 13 discharge for debtors who received a prior discharge within a specified window: four years for a prior Chapter 7, 11, or 12 discharge, and two years for a prior Chapter 13 discharge. The measurement runs from filing date to filing date.

Despite this statutory bar, no centralized enforcement mechanism exists. Enforcement depends on the trustee, the United States Trustee, or individual creditors identifying the prior filing and raising an objection. If nobody objects, the discharge enters automatically.

We built a tool to find the cases that fell through the gaps.

2. Data Sources

2.1 FJC Integrated Database

The Federal Judicial Center maintains the Integrated Database (IDB), which contains case-level records for all federal court filings. The bankruptcy subset includes fields for filing date, termination date, disposition, chapter, district, and prior filing indicators.

We used the Chapter 13 subset covering fiscal years 2008 through 2024. This dataset contains 4,895,163 cases filed across all 94 federal bankruptcy districts.

2.2 PACER Case Locator

The PACER Case Locator (PCL) provides searchable case data including attorney-case associations, filing dates, and disposition codes. We used PCL CSV exports for attorney-level analysis in target districts, covering 56,256 Chapter 13 cases in the Western District of Missouri, the District of Kansas, and the Eastern District of Missouri.

2.3 CourtListener RECAP Archive

The Free Law Project's CourtListener hosts the RECAP archive, a collection of millions of PACER documents contributed by users of the RECAP browser extension. We used the CL API for docket-level verification, attorney career tracking, and cross-district case identification.

3. Screening Methodology

3.1 Identifying Prior Filers

The FJC IDB includes a PRBANKFL field indicating whether the debtor had a prior bankruptcy filing. Of 4,895,163 Chapter 13 cases in our dataset, 1,627,116 (33.2%) had prior filings.

3.2 Matching Prior Cases

For each prior-filer case, we identified the most recent prior bankruptcy filing to determine its chapter and filing date. This step uses a combination of FJC cross-references, PACER lookups, and debtor-name matching with date validation.

3.3 Calculating the Gap

The statutory bar runs from the filing date of the prior case to the filing date of the current case. This is the filing-date-to-filing-date standard established in In re Blendheim, 803 F.3d 477 (9th Cir. 2015), which is the majority position.

Bar Windows

Prior ChapterBar Period
Chapter 7, 11, or 124 years from prior filing date
Chapter 132 years from prior filing date

3.4 Flagging Violations

A case is flagged as a potential violation when:

  1. The debtor had a prior bankruptcy filing
  2. The gap between prior filing date and current filing date is less than the applicable bar window
  3. A Chapter 13 discharge was entered in the current case

3.5 The Screening Pipeline

  1. Extract prior-filer cases from FJC IDB. Filter to Chapter 13 cases with PRBANKFL indicating a prior filing. Result: 1,627,116 cases.
  2. Identify discharged prior filers. Filter to cases where the disposition code indicates a discharge was entered. Result: 391,951 discharged prior filers.
  3. Match prior case details. For each discharged prior filer, identify the prior case's chapter and filing date.
  4. Calculate gap and apply bar. Compare filing dates and flag cases where the gap is less than the applicable bar window.
  5. Raw flag count. Initial screening produces a raw list of potential violations before verification.
  6. De-stale and verify. Each flagged case is checked against current docket records to confirm the discharge was actually entered and not subsequently vacated, converted, or dismissed.

4. De-Staling

The FJC IDB is a snapshot dataset. Cases that were discharged at the time of the snapshot may have subsequently been reopened, had their discharges vacated, or been converted to a different chapter. De-staling removes false positives caused by stale data.

4.1 De-Staling Process

For each flagged case, we verify against current docket records (PACER or CourtListener) that:

4.2 De-Staling Results

Of the raw flagged cases, approximately 12-15% were removed during de-staling due to:

5. Results

Final Count: 264 Verified Violations

After de-staling and verification, 264 unique cases remain where debtors received Chapter 13 discharges despite falling within the Section 1328(f) statutory bar window.

5.1 National Distribution

Violations were identified across multiple federal districts, with concentration in districts that have higher prior-filer rates. The national dashboard provides an interactive map with per-district results.

5.2 Attorney Concentration

A small number of attorneys account for a disproportionate share of violations. In our target districts:

5.3 Discharge Rates for Prior Filers

Of 1,627,116 Chapter 13 debtors with prior bankruptcies, 391,951 (24.1%) received discharges. This rate varies significantly by district, ranging from under 10% to over 50%. See the full prior-filer discharge rate analysis.

6. Limitations

7. Reproducibility

The complete source code, data processing pipeline, and documentation are available on GitHub. Researchers and practitioners can replicate the screening for any district or time period using the same methodology.

The eligibility calculator implements the same screening logic in a client-side tool that anyone can use to check a specific case. No data is collected.
