CFPB Consumer Complaint Case Studies: Reg E vs Reg Z in Practice

5 real-world dispute scenarios based on complaint patterns documented in the CFPB Consumer Complaint Database (consumerfinance.gov/data-research/consumer-complaints/). Each case illustrates where Regulation Z (credit) and Regulation E (debit) produce different outcomes in practice.

Note: These case studies are composites based on publicly documented CFPB complaint patterns. Individual complaint details are anonymised by the CFPB; the scenarios represent common fact patterns, not verbatim complaint records. Links to the CFPB complaint database are provided on each page.

About the CFPB Complaint Database

The Consumer Financial Protection Bureau (CFPB) publishes a public Consumer Complaint Database at consumerfinance.gov/data-research/consumer-complaints/ ↗ containing over 5 million complaints submitted since 2011. Complaints are anonymised and include the company response. The database is searchable by product, issue, state, and company. These case studies are based on common complaint patterns identified in that database.
