My question involves landlord-tenant law in the State of: California
My boyfriend and I had been dating about 6 months. He had been living with me "unofficially" since January, but kept his own small apartment nearby. We were very in love and decided to take the plunge and have him officially move in April 1. He started moving the remainder of his things in just before the 1st of the month. We had a rocky couple days at that time. He convinced himself that I had committed an emotional affair and possibly a physical one. I have never cheated and would never, I was trying to work these things out with him. Nonetheless, he was very upset with me and had a hard time accepting that I did not commit infidelity.
On April 4th I came home and he had all his bags packed and told me he was leaving me and that he could not trust me. He demanded I give him prorated rent for the rest of the month. He insulted me a few more minutes and I asked him to stop terrorizing me and leave. He left and now has been emailing me that he will take me to small claims court for the $719 worth of prorated rent. I told him I would give him back $311, which I got by deducting some items for which I felt he was responsible. He wrote back to tell me that was not good enough and that he would still be taking me to court for the remaining $$.
He was not on the lease. My landlords were aware he was moving in and we were waiting for paperwork to put him on the lease, but it never happened. He moved out too soon. Is there any likelihood that he could win in a court case against me?
At this point I just don't want to give him the money out of principle because of how horrible he has been. He also was threatening to call the police at one point because I wasn't available to let him come back and retrieve his music gear on the day he wanted (I asked him to come the following day). He's literally been terrorizing me. Any advice is greatly appreciated.
