What Documents Do You Need to File a Consumer Complaint in India?

Filing a complaint before a Consumer Disputes Redressal Commission under the Consumer Protection Act, 2019 is designed to be accessible. However, the evidentiary strength of your complaint depends heavily on presenting organized documentary records.

1. Proof of Purchase or Service Contract

The foundational requirement in any consumer dispute is establishing your status as a 'consumer'. You must present receipts, tax invoices, booking receipts, or signed service level agreements demonstrating consideration paid.

2. Written Correspondence & Defect Notices

Courts evaluate whether the service provider was notified of the deficiency prior to litigation. Retain all emails, WhatsApp exchanges, customer support ticket logs, and postal legal notices dispatched to the opposite party.

"Section 2(11) of the Consumer Protection Act, 2019 defines 'deficiency' as any fault, imperfection, shortcoming or inadequacy in the quality, nature and manner of performance which is required to be maintained under any law."

3. Affidavit of Evidence & Verification Statement

All facts alleged in your petition must be verified by a sworn affidavit. If electronic records (like emails or SMS chats) are relied upon, an accompanying certificate under Section 65B of the Indian Evidence Act (or equivalent under Bharatiya Sakshya Adhiniyam) is mandatory.

Summary & Next Steps

Properly compiling your documentary evidence before filing reduces procedural objections and accelerates interim relief considerations.
