dear sunil ji,

kindly elaborate on what is meant when you say the builder has sold the open space approved by municipality. is it common open plot, or open land or terrace? what is it indicated as, in the approval drawing?

for your reference, while your contention that open space cannot be sold by the builder, stamp duty department in gujarat very conveniently calculates stamp duty on such appurtenant land sold by the builder, and in fact has even specified that this land should be calculated at 30% of the rate specified for developed land

if you have copy of the approve drawing available with you, i do not think there is any information that you need to seek from the municipal corporation. the corporation has no mechanism to check the sale of such common land. you would have to consider the route suggested by someguy above.

further details may help understanding the matter better
