The mistake in the Challan remarks section may cause issues for you as a buyer. Here's why: 1. *Discrepancy in market value*: The incorrect market value mentioned in the Challan may lead to discrepancies in the registration process, as the Sub-Registrar may notice the difference between the actual market value and the inflated value mentioned. 2. *Tax implications*: The wrong market value may attract higher stamp duty and registration charges, leading to additional financial burdens. 3. *Future legal issues*: In case of any legal disputes or investigations, the incorrect market value mentioned in the Challan may be used against you. To resolve this: 1. *Get a corrected Challan*: Request the builder's advocate to issue a fresh Challan with the correct market value. 2. *Inform the Sub-Registrar*: Bring this mistake to the notice of the Sub-Registrar office and request guidance on how to proceed. 3. *Seek legal advice*: Consult a property lawyer to understand your rights and ensure you're protected from any potential legal issues. Remember, it's always better to address such mistakes promptly to avoid future complications.
