I had executed a Sle Deed of my plot in 2008 & handed over possession, in favour of a Purchaser. Purchaser had issued me the Cheques of total sale consideration, mentioned in the Sale deed. As per condition mentioned in the sale deed, the cheques shall not be presented for realisation, till I (Seller) will obtain building permission form Municipal Corporation Bhopal over the said plot. Inspite of best efforts from my side I could not get building permission on the said plot from the concerned authorities. Now, I want to get back my plot so please inform me the procedure for cancelling the sale deed. Purchaser is not willing for the same. Purchaser had only invested the amount of Stamp duty & registration expenses of the Sale Deed. Pl also inform whether I can get back my plot because today I do not want the amount mentioned in the sale deed because of rsie in market rates.
