My mother's father had a house in Hosangabad (M.P.) and it has 5 seprate portions. 2 portions having joint let bath area and 1 seperate portion having individual let bath area on the ground floor and 2 portion on the first floor having joint let bath area. My grand father(Nana) had done a registered will and as per that will ground portion are for 3 daughters(after the death of naani- as it has a condition that till she is alive she can stay on ground or enjoy the benefits of the property but she had not declared owner of property) and first floor portion for 2 sons. He specifically mentioned which portion to whom by mentioning the Directions in east, west, north and south side.
My mother passed away on 31st dec but before that the individual portions are transferred on the concerned person's name. My Mama(mother elder brother) also passed away but his wife stays alone in the house. She stays at my mother and her elder sister(my maasi) portion at ground floor. My mother elder sister filed a case against her(elder brother’s wife) to vacate the portion but later on we discovered that she had done a will with 3 witnesses by my nana’s wife in which its mentioned that ground floor both portions belong to her. Now my nani is also no more.
Further there are two shops constructed by nana on the ground floor falling under the portion of my mother and Elder maasi but my maami is claiming that her demised husband had constructed it and we don’t have any proof that my nana had constructed it. She had also given it on rent.
1. My question is whether a registered will (by my nana) can be changed by his spouse(Nani) ?
2. Since my mother demised her portion will belong to his husband or children.
3. The shop falling at the portion of my mother and my elder maasi will belong to them or to my maami?
