The sale of a property allows an immediate transfer of ownership. A certificate of sale facilitates transmission. The act refers to a contract concluded. The sale of real estate is linked to complex procedures. For a trouble-free transaction, all parties must understand the entire sale process, including legal knowledge of the differences between a purchase agreement and a sale instrument. There is an exception to the rule under section 53A of the Transfer of Property Act, 1882. Section 53A is intended to protect potential assignees (buyers) by allowing ownership of the property to be retained when a seller (seller) executes an incomplete instrument of sale and fails to comply with the conditions set out in the contract of sale. Although the contemptuous cannot disturb the possession of a buyer on the property, ownership nevertheless remains the domain of contempt.
