We, a Cooperative Housing Society of 8 members, have built a G + 4 house with two flats in each floor. The plot for the house was allotted by HIDCO, West Bengal. Mutation processes have been completed. The flats are ready for possession, only C.C. from HIDCO is awaited. My question is do we have to register the flats in the name of individual member of the society ? Is it required for future transaction ?
