This discussion concerns a property sale near Chennai where the market value (70 lakhs) significantly exceeds the guideline value (15 lakhs). The seller received an advance payment but the buyer later ceased communication. Now, the buyer is demanding registration at the guideline value with the remainder in cash, which the seller deems risky. The seller is also dealing with a false claim of a higher payment via an advocate's notice and is seeking guidance on how to respond and resolve the situation, including refunding the advance.
