Dear Experts, Need support for the following -- Ours is a Apartment in Ghaziabad ( UP) and we have Apartment Owner Association.(We are NOT co operative housing society). We have a registered sale deed of our apartment that gives us complete owner ship/clear title of Apartment and rights to use proportionate common areas. Problem Statement ( for which support is needed). We are seeking home loan from financial institution and they are asking for share certificate, and our apartment association says, share certificate is not applicable for apartments ( it is more applicable for Co operative Housing) What we done.. we are stuck .. financial institution is asking for share certificate and our apartment association says its not applicable. Is share certificate not applicable for apartments? Any reference to any act with clause number etc ( such as UP Apartment Act). Any other way..or response or document as a substitute/equivalent to share certificate that could satisfy the financial institution. Regards
