My father passed away recently. We own a flat in a society, registered in his name as the first owner and my mother and I as co-owners. Will my mother automatically inherit his share of the flat? And how can we get the official documentation to confirm this?

Yes, your mother will automatically inherit your father’s share of the flat as his legal heir. To confirm this, you can obtain a succession certificate from the court, which legally recognizes your mother’s inheritance. You can also get a copy of the death certificate and update the ownership records with the society and local authorities.
