My father wrote a will in 2012 for our ancestral property dividing it between me and my brother leaving my three sisters and mother. He expired in 2017 and mother in 2020 and my brother got property transferred on our name after submitting the death certificate. The will although talks about our ancestors property but at the end it says all his moveable or immoveable property should be divided between two sons.
Father did not mention the property which he owned in a different city alltogether which was transferred in 2005 on his name by me(I bought the property), because he wanted to give it back to me but couldn't do it before his death.
My brother is insisting on dividing this property between two of us leaving sisters once again based on this will which he wrote for property which my father inherited from my grandfather.
My sister's know the property is mine and they want to transfer their share to me.
My brother wants half at both places, I think he should get one fifth in ancestral as well as property which my father owns. That way I get 4/5 at both place coz my sister's want to give me the property in case my brother doesn't leave his share in the house I gave to my father. As per them the house should be given to me and let him take half of the ancestors property, but since he is adamant to take half in the house too we want to show him his share is 1/5 + 1/5 = 2/5 but he is getting 1/2 in the ancestral property already which is anyway more than 2/5.
How to undo the transfer done by the will in our ancestors property. I know this will is invalid but how to go about it so that brother comes to his senses when he actually gets 1/5
