I live in Los Angeles California and my original room mate (with whom I share the lease responsibilities) died leaving me an expensive apartment and I am currently unemployed. I rented my living room out to a woman who seemed nice and drew up a private contract that explained rent terms and said that I could evict her with two weeks notice (i figure this contract won't be helpful but I mention it anyways.) Well she soon turned into a nightmare, never paying rent on time and always smoking pot in the house and later I learned to my horror that she was prostituting herself through craigs list to pay rent. Last month I left town for the holidays and relied on her to deposit rent into my account. I rented my own room out to a friend who I put in charge of collecting mail. He leaves the mail for her every few days when he gets it. Anyways she didnt deposit the money so I asked her family members listed on facebook for her fathers name and phone number but refused to disclose the reasons out of respect to her privacy. I got a hold of him and he got a hold of her and got her to pay rent however she freaked out and said she would be suing me for harassment. I said that was fine and gave her notice to move out by the end of the month via text message. This was on the 7th on the month. I contacted her again today (the 26th) to remind her and she said that she had contacted the post master to let them know that I had been withholding her mail (a very serious and untrue accusation,) that she had reported the fact that I Was illegally subletting my apartment (this is true to my knowledge as I never updated my lease but the on site manager was aware of it) and that she had a letter waiting for me from her attorney when I got home (on the 30th of the month.) I am deeply concerned about what to do and would appreciate any advice. Although my contract that I drew up with her states my right to change the locks if she doesn't pay rent by the 3rd of each month I'm guessing that I cannot legally do that without going through the long eviction process. So obviously there are a lot of questions within this question and any insight to any particular parts is greatly appreciated. My main points of concern are as follows:
What legal actions can she personally take against me?
What precautions (if any) can I take to protect myself?
What is the quickest way to have her legally removed from the apartment?
As I said from the start I am living pay check to paycheck and relying on both of my tenants to pay me on time to pay rent, I have close to no resources. Please help me, anyone! Thanks to everyone who takes the time to read.
