Evidence That Actually Works in Consumer Forum: A Practicing Advocate's Checklist

Evidence is the backbone of any consumer complaint. You can have the law perfectly cited and the prayer perfectly drafted, but without compelling, properly presented evidence, the forum has nothing to base its order on.

Consumer forums are not as procedurally rigid as civil courts, but they have firm expectations about documents. Documents filed incorrectly — without proper exhibit marking, without attestation where required, without an index — are either ignored or returned with directions to file them properly. This causes delay, costs adjournments, and in the worst case, leads to an adverse order because your evidence was not properly on record when the hearing happened.

The Index of Documents: Your First Obligation

Every consumer complaint must be accompanied by an index of documents. This is a numbered list of every document you are filing — the document name, the document number in your file, and the number of pages. Without an index, the forum member cannot track which documents you are referring to in your complaint.

Filing without an index is a small detail that marks out a party-in-person immediately. It also creates practical problems — during the hearing, when you say 'I filed the warranty card,' the forum clerk has to search through loose papers. An indexed file with clearly marked exhibits is handled professionally and remembered respectfully.

How to Exhibit Documents Correctly

Every document you file must be given an exhibit number. The convention is: exhibits filed by the Complainant are marked 'Exhibit C-1', 'Exhibit C-2', etc. Exhibits filed by the Opposite Party are marked 'Exhibit OP-1', 'Exhibit OP-2', etc.

In the body of your complaint, each time you refer to a document, you must cite its exhibit number. Do not write 'I have attached the purchase receipt.' Write: 'The Complainant purchased the product vide Invoice No. ABC123 dated [date] for ₹45,000/- (Exhibit C-1).'

This creates a direct link between your narrative and your evidence. The forum member can immediately turn to Exhibit C-1 to verify what you are saying. This is the difference between evidence that is considered and evidence that is ignored.

Documents That Consumer Forums Accept

• ✗
  Purchase receipts and invoices

  Originals are preferred. If original is unavailable, a clearly readable photocopy with a notarised affidavit attesting it as a true copy is accepted.
• ✗
  Warranty cards and product documentation

  Original warranty card, if any. If the warranty is embedded in the product packaging or a booklet, file the relevant pages.
• ✗
  Written communication — letters, emails, notices

  Printed copies of emails are generally accepted. Print the full email header showing sender, recipient, date, and subject. WhatsApp messages should be printed as screenshots with visible timestamps; longer conversations should be summarised in a separate affidavit.
• ✗
  Service records and job sheets

  Any service centre job card showing the reported defect, dates of service attempts, and the outcome.
• ✗
  Medical reports and prescriptions

  In cases of deficient medical service or injury caused by defective products, original reports from hospitals or doctors, or attested copies.
• ✗
  Photographs and videos

  Photographs of defective products are accepted. For digital photographs, print them clearly and file them as exhibits. Videos on pen drives or CDs are accepted but must be indexed. For WhatsApp videos, include the message context.
• ✗
  Bank statements and payment records

  For disputes involving payments, unauthorized debits, or financial services — official bank statements or account transaction printouts with the bank's letterhead.

What Commonly Gets Rejected or Weakened

Blurry photographs or screenshots that are unreadable after printing. Before filing, verify that every document is legible at the size it will be printed.

WhatsApp message screenshots without context. File the full conversation, not just the message that helps your case. Forums have seen selective editing and will call it out.

Documents in regional languages without a certified translation. If your document is not in English or the language of the forum's state, a certified translation is required.

Documents from unknown or unverified sources. A screenshot of a review on an e-commerce platform is weak evidence. An affidavit from the complainant describing the experience and attaching the screenshot as an exhibit is stronger.

The Verification Affidavit — Often Missed

Every consumer complaint must end with a verification by the complainant — a statement under oath that the contents of the complaint are true to the best of the complainant's knowledge and belief, and that the complaint is not frivolous or vexatious.

This verification should be sworn before a Notary Public or a Magistrate. A complaint without proper verification is technically deficient. Some forums are lenient about this at the admission stage, but it must be regularised before the final hearing.
