I purchased a property from a state financial corporation under open bid in the year 2000. As my bid amount was highest, I got the property"s sales confirmned in my favour. After that we entered in to Agreement to Sale which is on plain paper. As per terms of the corporation I had to make payment in 3 years which I did accordingly. But I could not get the property registered in my name due to shortage of funds at that time. Now I want property registered in my name for which state financial corpration is asking stamp duty as per current circle rates which is more than five times higher than old rates. I have already made payment of property 9 years back. I am unable to understand why I am required to pay stamp duty as per current circle rates.I therefore request the learned panelists to inform whether I have to pay stamp duty as per old rates or current circle rates ? I shall be highly grateful for all of you.
