My father and my mother are joint owners in an Non Agriculture land in Pune region. My father expired few years ago. I have only one brother and no sister. In this case I wish my mother to become 100% owner of the N.A. Land. Do myself and my brother have rights in the property? What is procedure to make my mother 100% owner so that she can transfer or sell entire land [Please give section / (Sub-Section) if possible]?
