Your sister is asking for a share in the property of your grandfather from your father.
In fact your father had given a sizeable property to your step mother, then why is he denying the same privilege to his own daughter.
However as per law your sister cannot claim any share in the property that is lying on your father's name as a right, at least not during his lifetime.
If she is going to court, allow her to proceed, which can be challenged as per law properly.
Her case is not legally maintainable.

If the property was a self earned or in the name of your father, it is his sweet will to shsre, else her attempts may not succeed.
