My question involves landlord-tenant law in the State of: California
My boyfriend and I moved into a room in a friend of ours' house. We signed no rental agreement and she did not collect a security deposit from us. We moved out of that location on November 17, 2012 and I thought everything was fine. Until 4 days ago (6 months after we have moved) I received an itemized list of cleaning charges for the room that we rented. I think it should also be said that we left the place in the same, dirty unvaccuumed condition as when we moved in. She is requesting a total right around $600 and I would like to know if I am obligated to pay her or not. The way I see it, if she wanted to be a serious landlord she should have started from day one with a written rental agreement and security deposit.
