I am from Bangalore and I have been told by my builder that the Car park charges also will be included in the cost while computing the stamp duty for registration. My understanding is that Car park is part of the common area for which they claim an amount separately. Also when they explained, they computed the Stamp duty on the Super built area and not on the UDS of land. Can you clarify if the super built area which includes my flat also would be considered for comutation of stamp duty or should it be only on the UDS of land which will part of the sales deed.
