I have sold a plot to a buyer 7 years ago. The land is on my father':s name. At the time of selling, my father is no more and we submitted his death certificate. In addition, my mother, myself and my sister submitted aadhaar and signed on the sale deed. Now, the buyer is calling us daily to submit legal heir/family member certificate. He is saying he needs it for bank loan (to build a house in the plot) and will proceed legally if I don't co-operate or submit certificate . Can you please advise if I have any legal liability from the buyer, as I don't have legal heir/family member certificate
