We have done ‘agreement to sale’ for a flat on 28th March 2013... but Sale deed was pending, which will be done after paying final payments to the vendor/seller, Now on 11th April have cleared all the payment. We have paid all the stamp duty while doing agreement to sale. so for sale deed Do I need to pay LBT ?... How do I pay it now, as I have already paid 5% stamp duty when we registered the flat ?
