Generally speaking, if a person is a part owner of the house, he has the right to reside there. You could exclude him from the house if you had good reason to believe that he is a danger to the people who live there. You could seek an injunction to keep him out of the house, but you would have to show, in a sworn statement and very likely at a court hearing, that he has said or done things which would pose a danger to you or your children.
