Subletting without a written contract
I am subletting a room in my 2 bedroom apartment. My landlord was OK with that and did not require for me to and the subtenant to sign a lease. There was only a verbal agreement between us and email communication where he (subtenant) agreed to pay the rent. It has been only 2 months and the subtenant said he does not have this month's (Jan) rent. He doesn't know when he will have some money. He is being very disrespectful to me, using foul language, screaming on the phone, committing nuisance. I even had neighbors complain to me while I was at work. I asked him to move out and he now broke the door the bedroom he is staying in because he locked himself out of the bedroom and can not afford to call a locksmith. I do not know what to do. He came in and I even gave him a mattress to sleep on. He had nothing else but his clothes. I fear he will damage the apartment when I'm at work. I would not mind putting his clothes out of the apartment and changing my locks but I'm not sure if it's legal. I asked him to sign a 30 day notice to vacate and he did not want to talk to me. Please help me with any advice. Thank you.
