Before acting on your own on the basis of half hearted information get copy of mutation records with all link docs and show these to a very able senior LOCAL counsel specializing in revenue/property/civil matters and confirm if the nature of the property in the hands of your father is self acquired or ancestral……..
If you consider yourself then count 4 generations…..
Property inherited by a Hindu from his father, father’s father or father’s fathers’ father, is ancestral property….. Any property acquired by the Hindu great grandfather, which then passes undivided down the next three generations up to the present generation of great grandson/daughter.
Self acquired property can become ancestral property if it is thrown into the pool of ancestral properties and enjoyed in common.
You have posted that; Your father is alive.
