The contract of sale may, or may not, lead to an actual sale of the property in question. Some stamp duty laws, such as the Maharashtra Stamp Act, provide for an agreement to sell real estate as an appropriate deed of transfer and are therefore subject to the same stamp duty as that applicable to the deed of transfer or deed of sale of real estate. Under these provisions, which require payment of stamp duty on a contract of sale, persons wrongly perceive a contract of sale as a deed of sale in due form. Under the Transfer of Ownership Act, a contract of sale, with or without ownership, is not a transfer. Section 54 of the Transfer of Ownership Act provides that the sale of immovable property may only be made by a registered instrument and that a contract of sale does not generate interest or costs for its property. . . .
