Hi, My wife and I are living with my father-in-law and he is causing issues between me and my wife, and between me and him. My wife and I are mortgage holders and he had gifted money to my wife as her inheritance to put towards the house. He lives on the property with us in a portable home that has not been fixed on the property (basically a large caravan). Now he keeps saying that he can do whatever he wants and now he wants to get my wife's mother on the property as well in a granny flat. I did not agree with this and he says I don't have a choice. Who has the rights here? I'm paying mortgage on this property, shouldn't my wife and I have final say?
