Location: Bozeman MT I let my ex wife move in almost a year ago and she has never paid rent and just sits around all day. No job and doesn’t seem interested in getting one. I’m trying to evict her. I had her sign a lease that stated she has a month to month contract. I mailed her first class 3 day failure to pay notice but now I’m confused. Can I serve her with a 30 day eviction notice? Or do I have to take her to court? She has no key and just uses a key pad to enter. Can I just change it? From what I’m reading it seems like a civil matter and the only thing she can do is sue me. Which she owes me about 45k from lending her money over the last 5 years so I don’t see her winning. I more concerned with getting arrested? Thanks for any help.
