Share certificate documents

In which State is your Society? Laws change from State to State.

Its Maharashtra, also I'm trying to transfer share certificate to my mother not to any outsider person.

Please advice.

Under the Maharashtra Co-operative Societies Act an Associate Member or a person whose name appears not as the first member in the Share Certificate is not the co-owner of the flat. He or she will have a right to vote as proxy under Section 27(a) of the Act and nothing else. Under the Model Byelaws an Associate Member automatically ceases to be such member or any other kind of member on the death of the primary member. On the death of a member the interests in the Capital and Property of the Society of the deceased member will be transferred to the nominee/s if the diseased member had nominated one or more during his lifetime. If the flat was jointly purchased by your father and mother and your mother's name appears as joint owner in the sale/purchase deed, your mother can claim beneficial interest in the capital and property of the society. On that basis your mother can apply to the Society for membership. Otherwise if your father had not made any nomination you will have to follow the succession certificate route.
