Not at a moments notice. They can however ask you to leave within a certain time frame. Ex: If you pay week to week, they need only give seven day notice. If you pay month to month, they need only give 30 day notice. Most states follow this criteria.
Depends. Call an attorney
If your on the lease they can't kick you out.
We paid rent for two mounth s but there trying to tell me and my girl to pack our things because march there moving out can she do that
If you and your girlfriend are on the lease or rental agreement, then I do not think they can. You would have to talk to the property manager or landlord. If neither of you have any paperwork to the contrary and there is no paper trail....you may be SOL.
