This question is a flat in a housing society building in Navi Mumbai. We bought this flat in Navi Mumbai, MH from a bank in auction in 2006. We obtained all the neccessary paper work which they got the deed, share certificate, transfer documents etc. Just recently the society has posted a notice asking all its members to give their deeds to the society secretary and that they will be issuing fresh Share certificate for all its members. I am not sure this is possible. How can a society do this. Appreciate your guidance.
