Consumer Complaint Data
The CFPB (Consumer Financial Protection Bureau) tracks consumer financial complaints. Lacy Katzen LLP has been named in consumer complaints.
These are voluntary, self-filed consumer complaints, not a substantiated-wrongdoing rate: a larger firm with more clients typically shows more complaints simply from serving more people, and CFPB does not verify a complaint's merits before logging it. Read the count as consumer-outreach volume, not a professional-conduct score.
