A seller executed a sale agreement for a panchayat-approved property at a reduced price due to a 90-day registration window. However, government bans on registrations and new revenue acts have introduced a significant additional cost for DTCP/Municipal approval. The seller argues the buyer should bear this cost or the price should be revised, while the buyer insists the seller must cover it. Both parties are unwilling to cancel the agreement, leaving the seller seeking advice on how to proceed.
