If it is the self acquired property of ur father, u have no right or claim in the property and there is no law to force ur father.
You and ur second mother are already legal heir of your father. But that will be considered after the death of your father.
I am his son from first wife, my mother died several years back. My father is living with my second mother in a seperate house. The property thats on my father's name is vacant noone lives there. My father want to make my second mother and second brother as nominee of his property.
My question is - Is he free to nominate anyone he want to?
