A stamp duty of 6% is applicable and mandatory on flat purchases within the jurisdiction of Greater Mumbai Municipal Corporation and 6% on flat purchase within TMC judiciary limits, according to the Maharashtra stamp act 1958. Without the payment of this stamp duty, your solicitor will not be able to officially register your new house in your name, even when the house is transferred within the family. The rate of stamp duty for galas/office/shop premises and garage even if just used for car parking is 5% in Mumbai.

The stamp duty amount is calculated for the flat purchaser as per the agreement value or market value, whichever is higher. Once the stamp duty amount is ascertained, the flat purchaser needs to prepare a pay-order addressed in favour of "SUPERINTENDENT OF STAMPS, Mumbai". The pay-order is given for franking of the agreement. Later, the said agreement is duly filled and signed by the respective parties.

Registration of the Stamp duty paid agreement document is to record ownership of the flat.It is registered under the India Registration Act with the sub-registrar of Assurances, of the jurisdiction under which the property is located. The purchaser officially becomes the legal owner of the property, only after the title deeds are registered or recorded in his/her name.
