Long term capital gain

Thanks a lot Sir, The property was acquired in the year 2004 so it must be Long term capital gain

Agreement to sell is like a MoU signed and executed on a non-judicial stamp paper, which precedes the actual conveyance of the property via a sale deed. Unlike MoU, agreement to sell is legally binding on both the buyer and the seller in respect to the terms and conditions agreed upon between the two. On the date of actual conveyance as mentioned in the agreement to sell, the parties execute the sale deed. The question is whether any stamp duty was paid on this agreement to sell.

I appreciate your clarifications. The agreement to sell was done through Notary and there was no stamp duty paid

If this property is a residential flat, I don't know how the society transferred the flat on the basis of a agreement to sell. It is not a valid transfer document. 

This is only a leased plot of land and the plot of land was bought under power of attorney and agreement to sell
