So to my knowledge, he's not a tenant I'm not charging him rent and the home is my current residence. There is no rental agreement to break. I have given him ample notices with deadlines and stipulations that have been broken.
So even in a charitable interpretation where I am a landlord and he is the tenant I'm basically over the first step where I have given notice already and will just need to proceed with starting an eviction case with the courts.
