Short payment of land registration fees

What was the requirement of "agreement" for relinquishment of your share/right in favour of "other" shareholder of the property, as stated by you ?

There is change in circumstances/ facts or misconception qua agreement and relinquishment.

To err is human, the mistake might have been pointed in regular audit, selected checks by Higher authorities.  The charges if demanded has to be paid.    Pay the demanded amount as the amount may not be substantial.

You are required to pay if the demand is legitimate and reasonable.

The amount of Stamp duty is Rs. 70,000. Which is a huge amount for me.  Thanks!

Please go to the office and seek such specific reasons for demanding such a huge court fee.  They will show you the value fixed for such locality, the fees recovered from others, the rates fixed for that locality, and the mistakes committed by them in calculating fees.   One can not benefit out of a mistake, oversight, and most of the time, it came into the light where purchasers managed with authorities for less valuation, and during such audit, those were specifically pointed, the amount was demanded from such purchasers.   Purchases on the basis of land rate and not on stamp value for registration.  It is your decision either to pay or face consequences.
