Secondly, I don't quite understand what you said about the old people being assigned to the boss's name, so some things you said are not very understandable, so there is no way to judge and answer. However, we can be sure of some legal knowledge: 1, all children have the obligation to support the elderly; 2. If the old man has his own property, he can decide who to give it to, but if he gives the property to a child, he must go through the transfer formalities. If the old man didn't dispose of his property before his death, or didn't make a will, he will inherit according to law after his death, that is, all three sons and one daughter have the right to inherit one of them and share it equally, but those who refuse to support the old man can get no or less points; If the house is the name of the eldest son, not the property of the old man, the old man can't get it back, because whose name is registered on the real estate license. Houses in rural areas generally only have land use certificates. If the name of the old man is confirmed, it means that this is the old man's house. Then the demolition fee should be given to the elderly. As for the boss building a house, you can make compensation, because the specific situation you mentioned is not clear, and the question of demolition fee is not easy to answer clearly.
