My grand father has 2 wives and 1st wife is my grandmother, she had my dad, my dad’s younger brother and one sister, my dad is the elder one. grandpa's 2nd wife has one son.
My both grand mothers expired in 1970’s and then my grand father has divided the property equally between his 3 sons(my aunty is married by that time and have the property division documents) and the other grand mother son has been living separately from then.
Now, I am the only son to my father and my father’s younger brother is not having any kids and we are living all together(but we are having 2 different ration cards) and the other grand mother son is having 3 sons.
Now I want to know if the my grand father's second wife son- son's have any rights on my father’s younger properties(some properties are inherited, some are self occupied)?
If my father's brother makes a WILL on my name or my kids name will my grand father's second wife son- son's challege me?
