A purchase agreement is an agreement to sell a property in the future. This agreement sets out the conditions under which the property in question is transferred. The Transfer of Ownership Act of 1882, which governs matters relating to the purchase and transfer of real estate, defines the sales contract or a sales contract as: that an unregregtored sales contract, with the surrender of the property to a detainee, may be received as proof of the agreement as proof of the agreement and if an appeal for a given benefit would be based on an unregord sales agreement: which must be answered, is whether an unregord sale agreement, which is acquired by the delivery of the property or is carried out for the benefit of a person in possession, i.e. an agreement that indicates a part of the benefit , a sale agreement covered by Section 53A of TPA, may constitute proof of the agreement and whether a legal action for a given benefit would be based on such an unregured sale agreement as evidence. The purpose of Section 53A of the TPA gives the defendant the right to protect his property from the vector. It is also available against those who assert their rights under its care, such as heirs, rights holders and final agents. This section should be used in an orderly manner as a defence and not as a weapon of attack. There are a large number of projects in progress in which the developer may have asked the buyer for more than 10% of the cost of the property under the ATS and may have been donated by him, which were (in the absence of requirement) and are still not registered. In the absence of contrary legislation, an ATS has not been registered in accordance with industry practice with respect to real estate exported both between individuals and between developers and Allottees.

As the law did not provide for registration, ATS was also not exposed to the consequences of section 49 of the Registration Act. Therefore, the courts and especially consumers for has, used to make these unregistered ATS effective. There is no savings/deeming system under the law that takes into account the fate of unregistered ATS exported before May 1, 2017. In order to determine the fate of these ATs, the law could have been considered to have been registered under the Act before May 1, 2017 (subject to payment of a royalty to the relevant sub-registry), provided that even the ATS that were executed before May 1, 2017 are registered within a specified time frame, as required by the registration of current projects pursuant to Section 3 of the Act. A sale agreement can generally be defined as an agreement listing the terms of a possible sales contract, as well as the counterparties and payment details offered. When selling the property, this is one of the important documents, because the deed of sale is based on it. It allows the sales process smoothly by explaining step by step. This helps to improve understanding between the parties and their specific roles in sales.

Section 17(1A)[1] of the Registration Act, 1908 provides that “documents containing contracts containing contracts in return, all lands within the meaning of Section 53A of the Transfer of Ownership Act of 1882 are registered if they were executed on or after the beginning of the Registers and Other Laws Act 2001 and these documents are not registered on or after that date, they have no effect for the purposes of Section 53A.” This section of the Registration Act expressly states that if the sales contract is not registered, it has no effect within the meaning of Section 53A of the Transfer of Ownership Act of 1882. This means that an unreged sales agreement cannot be admissible as evidence. Section 53A of the TPA deals with partial benefit when a contract for the transfer of property between the assignor and the assignor, who is or is already in possession of the property or part of the property, is still in possession of the partial performance of the contract and the purchaser`s action has been or is ready to be part of the contract
