If you agree a price at a private meeting but the seller later demands more money — what can you do?
If a contract was formed at the meeting — offer and acceptance on the specific note at the specific price — the seller has no legal right to demand more money. The contract price is fixed. A seller who demands more after a contract is formed is attempting to extract additional consideration for an obligation they are already bound to perform. If they refuse to deliver at the agreed price, it is a breach of contract. If they apply threats or economic pressure, it may be coercion rendering the contract voidable.
The contract price is fixed on acceptance
Once the seller says 'yes, ₹10,000 for this note' and the buyer accepts, a contract is formed at ₹10,000. The seller's obligation is to deliver the note for ₹10,000. The buyer's obligation is to pay ₹10,000. These obligations are fixed by the contract — neither party can unilaterally change them. A seller who says 'actually I want ₹12,000' after the contract is formed is not making a new offer — they are refusing to perform their existing obligation unless paid more. This refusal is a breach.
The buyer's response: state clearly that you hold the seller to the agreed price of ₹10,000 and that any refusal to deliver at that price is a breach of contract. Send a WhatsApp message making this demand: 'We agreed ₹10,000 for [note description] at our meeting on [date]. Please confirm delivery at the agreed price. Any change in terms is a breach of our contract.' This message creates a documentary demand and the seller's response (or non-response) is evidence.
Coercion — when price increase demands become criminal
Section 15 of the Indian Contract Act defines coercion as committing or threatening to commit any act forbidden by the BNS, or unlawful detaining of property, to cause a person to enter into an agreement. If the seller threatens to harm the buyer's reputation, to withhold the note they have already received partial payment for, or to cause any other threatened harm unless the buyer pays more — this is potentially coercion.
A contract obtained through coercion is voidable at the option of the person whose consent was coerced. If the buyer paid the additional amount under pressure, they can void the contract and recover the excess amount paid. The appropriate remedy: void the transaction, recover the overpayment, and file a consumer forum complaint. If the threats were explicit criminal threats — threatening physical harm, for example — file a BNS complaint.
When the price was not yet agreed — the offer/counteroffer situation
If negotiations were ongoing at the meeting and no final price was agreed — both parties left with different understandings of the price — no contract was formed. In this case, the seller's later demand for a higher price is simply a new offer, not a breach. The buyer can accept the new price, counter-offer, or walk away. This is the importance of confirming the agreed price in writing immediately at the meeting.

Seller demanding more after contract: no legal right to demand more after offer and acceptance. Contract price is fixed. Response: WhatsApp demand confirming agreed price and stating any change = breach of contract. Coercion (ICA §15): if price increase demand is backed by threats = coercion; contract voidable; recover any excess paid. No contract formed (ongoing negotiations): seller's new demand is a new offer — buyer can accept, counter, or walk away. Prevention: confirm agreed price in WhatsApp immediately at the meeting.
