My question involves real estate located in the State of: California
There are multiple families renting different parts of the house, but one of the families children, and even sometimes the mother ends up in my part of the house. The kids will run through my hallway and make my kids leave their own rooms. The mother will eat out of my fridge, and tell my kids to move to a different room, even if it's their own bedroom, while they are trying to sleep so that her kids can play. She also does not let anyone go upstairs, where she is renting, even if her kids invite my daughters up there. Please tell me I have rights against this.
