GM, I think you should talk to a lawyer. You may be able to remove her, if she is dangerous, without having to worry about eviction laws. I definitely do think December is a long time away if your daughter is a threat to kill you. Sadly, my son was also a danger to me. I didn't call the police. Maybe I should have. Instead, he left one day and I never allowed him back in. As smart as he is, and he is VERY smart, he never thought of eviction laws, nor did I since I'd never thought about it as an eviction. He did not come back or try to get back into the house. If he had, I may have had to call a lawyer because he was not only dangerous to me, he was dangerous to my daughter.
I always think it is very sad when those we love abuse us. When it is our children, it is the saddest of all. But parent abuse is getting more publicity lately and it is far more common than we ever realized. And it is no more acceptable than parent's abusing children. Abuse is abuse.
Hang in there and we are here for you.
