Wife Ancestral land property question

Hello Sir/Madam, I want a legal opinion on below case My father in law has 2 brothers and their father had a land on his name which becomes an ancestral property. My father in law’s elder brother , got NOC signed from my father in law and his other younger brother and sold the land . So only my father in law’s and his brother’s NOC is required as it is ancestral property or even my wife’s and my other father in law daughter’s NOC is required. As my wife and her sister have no problem , can I (son in law) file a case to lock the constructed house on sold land ?
