How to build a consumer complaint evidence file

A strong complaint file is easy for someone else to review. If a reviewer can understand what happened in under five minutes, your documentation is probably in good shape.

Use a simple folder structure

• 01-chronology
• 02-contract-and-terms
• 03-payments-and-invoices
• 04-correspondence
• 05-remedy-request

Core checklist

• Start with a one-page chronology.
• Include receipts, terms, and key correspondence.
• Label each file with date and source.
• State the remedy sought in one sentence.

Prefer filenames such as 2026-05-14-email-refund-request.pdf over generic names like screenshot-final2.png. Clear naming reduces dispute about sequence and context.
