Rectification of sale deed and costs involved

There is no much cost involved and only a standard fees.Regarding this check with your Registrar office.I would prefer you execute the same at the earliest when your seller is co operative it self

I have just discovered that rectification charges are the same as registering new property (Stamp Duty + Registration Charges). A little bit confused as to why it should be.

You try to understand first what you are saying is correct but you have to pay the stamp duty and registration fee in accordance to the increase in guideline value for  the difference amount only.For example at the time of your earlier registration if the guide line value is Rs 10 lacs as per the sale deed and if the present value as per guide line value of Registrar office is 12 lacs you have pay the stamp duty for the difference amount of 2 lacs only.Please check with Registrar office

Thanks Narasimha. That really helps. I just wanted to understand better before taking to a Registrar. So for the clarity of others, I am extrapolating.

Guidance Value for 1 acre when first bought = 1 lakh

Guidance Value for 1 acre during time of Rectification = 2 lakh
