Dear Client,
An associate member is defined to mean “a member who holds the right, title and interest in the property individually or jointly with other but whose name does not stand first in share certificate”. This mean he shall be co owner.
He hold joint ownership up to 50% and after his death, his share will transfer in his legal heir by equal share. This mean if his son is only surviving heir and non else alive than only son is absolute owner. Otherwise for selling the flat, others involvement will also required.
After father death, share certificate will transfer in nominee. I don`t feel this certificate valid.
