We are residents of a MHADA bldg in Vikhroli. My next door neighbour, an illiterate woman, on passing away of her husband, filed an application with MHADA for the flat to be transferred in her name. She submitted everything including a copy of the old allotment letter. MHADA wrote back saying that they could not trace their ownership records (they bought the place from the original allottee with proper documentation). It was a plain printed letter with a sign but no seal and sent through ordinary post. She has been to their office. They keep saying the same thing to her over and over again. What should she do?
