Dear Client,
In the Present Scenario, you are purchasing a shop in the complex that was built in 1988. This shop had been sold and purchased for four times, and you are buying it with the present owner. The Owner has all the relevant documents and got the due diligence test done as well. However, the only concern you have is that, the original of the old document is not present with the present owner, but you had nevertheless received the true copy of that missing document from the Registrar's office for your reference. Herein, though its better to have all the original documents, a missing document does not invalidate the transaction of sale made, as you also obtained a true copy now. Furthermore, according to the Transfer of Property Act, 1882, the seller must have a clear title for the transfer of ownership. Since you have verified the other documents, it validates the transfer. However, there may be disputes that arise in future with regard to the continuity of the title. But, since you have the true copy, it serves as an evidence to the previous ownership. Hence, you may proceed with the purchase of the shop, but it is suggested that the implications of the missing document have been taken care of at first, so as to protect your interests in the future.
Hope you find this answer beneficial for resolving the dispute.
