1. Sale of parking space is illegal. In 2013, the Bombay High Court ruled that approved parking spaces within a building were common areas for society members and could not be sold. Developers circumvent the restriction by collecting payment for car-parking spaces in cash.
However, Under the new rules, approved parking spaces, both covered and open, can be sold. In a bid to regulate it, the government has mandated that developers must formally disclose details of this sale. The government has also permitted builders to demarcate such parking spaces sold. Prevailing rules grant the cooperative housing society the powers to distribute parking space among members.
If the vendor has a legal document to prove that he owns the car parking space, you may obtain that and get a registered sale deed executed on that basis in this regard.
2.If this purchase is to be effected through a registered document then necessary stamp duty has to be paid accordingly.
