Asked in Civil
From the nature of your question it is assumed that your father is dead or divorced by your mother. Thereafter your mother remarried. Now your mother has also died. She has left properties. You don't want your step father to get a share of your mothers properties. Is not this your problem? But unfortunately he has a legal right to one equal share.
Husband is also a 1st degree legal heir of deceased wife and not the children alone.
