So all your father and mother's property will be split to two part. One part is your mother's and the other part is your father's. Your father's property will be shared amoung his wife, children and parent(if any still live).
But even your brother and you get the right, you have no way to kick your mother out. She has most part she already has 50% already and plus hire her part.
What you can do is get your part and give it to your mother. She will have more owner's right.
