This is to inform that I am going to purchase an apartment from a person 'X' (purchased property in 2004) who had in turn purchased the same property from "Y " seller (1st transaction of the property1992). The person X had informed me that the original sale deed of the above property has not been collected from "Y". When contacted "Y", was inturn asked to contact her lawyer. Mrs Y is no longer staying in India. The lawyer says they had all the deed but was destroyed/lost/misplaced as it has been quite a while. Kindly inform me what is the procedure and legal doc required insuch cases.
