Dear sir, I own a flat in Navi Mumbai. I use the open car parking space which is not allotted to any member in particular for parking my car. The society used to charge an amount of Rs.100/- per month as the parking charge . But from August 2013 onwards it has been charging an amount of Rs.1000/- per month as car parking charge. Is it legal?
