My wife's daughter and granddaughter and the daughter's boyfriend have been living with us for almost a year. There has been fighting between the boyfriend and my wife mostly words. Her daughter has attacked my wife and we had the police to remove them temp. how do I make the move out permanent?

Can you get a restraining order or order of protection which restricts them from coming back?

But beyond that, since it has gone so far, get a local attorney to handle an eviction proceeding
