What documentation should a buyer always obtain when purchasing at an exhibition?
An exhibition purchase without documentation is a purchase with no legal protection if something goes wrong. documents obtainable in under two minutes at any stall — convert a casual cash transaction into a legally defensible purchase. The serial number photograph is the single most important, because it uniquely identifies the specific note and connects it to the seller and the price paid.
The five minimum documents
Document 1 — The receipt. Any written acknowledgement from the seller showing: their name and contact (phone or WhatsApp number), the date, a description of the item sold, and the price paid. It does not need to be a printed form — a handwritten note on any paper, signed or initialled by the seller, is legally sufficient. If the seller has a stamp or visiting card, use that. If not, ask them to write on any paper. A receipt that takes 45 seconds to produce protects both parties.
Document 2 — The serial number photograph. Photograph both sides of the note at the stall before handing over payment. The serial number and prefix must be clearly visible. This photograph — timestamped by your phone's camera — establishes precisely which note you purchased, in what condition, at what time. It is the note's unique identifier. If you later receive a different note, or if the note is claimed to be different from the one you paid for, the photograph establishes what was agreed.
Document 3 — The seller's contact details. Name and WhatsApp number at minimum. If the seller has a visiting card, take one. This establishes who you transacted with — necessary if you need to contact them for any reason after the exhibition, and necessary as the identified defendant in any consumer forum complaint.
Document 4 — Post-purchase WhatsApp confirmation. Within minutes of completing the purchase, send a WhatsApp message to the seller: 'Purchased from you at [exhibition name]: [note description], price ₹X, paid by [cash/UPI]. Thank you.' If the seller replies — even just a thumbs-up — this creates a written confirmation of the transaction. If they do not reply, the sent message still timestamps and documents your record of the transaction.
Document 5 — Seller stall photograph. Photograph the seller's stall, ideally with the seller visible and their stall number or location identifiable. This is contextual evidence placing you with the specific seller at the specific event. Combined with your phone's location timestamp (if enabled), it is difficult to challenge.
