I brought a flat from my previous owner a year ago. I made a mistake that I didn't noticed the documents properly. I have all the mother documents expect the sale deed between my previous owner and the builder. Now I asked him about the original sale deed he said that he had handed over all the doucments to me but I have only the photostat copy and not the original. But i am not having that now. Well I can't file a complaint against him and further i am not in such a situation too. My question is shall i lodge a complaint that the sale deed is missing by myself and what procedure I have to do further to solve this problem
