A family sold land to a real estate firm in 2012, with an agreement that the firm would sell a plot back to the family for Rs. 6 lakhs within two months of layout formation, or repay double the amount. The family has been requesting implementation, but due to the elderly seller's age, no legal action was taken. The plot remains unsold, and the family is now asking if they can still pursue legal proceedings, under what provisions, and if a notice is required. The advice suggests consulting a local lawyer with all documentation, as the validity of the claim depends on the original agreement's registration and stamping, and the passage of time since 2012.
