Can a landlord ask people to leave if their names do not appear on the lease? Even if they are helping to pay rent?
Yes, the landlord has the right to ask people to leave the premises if their names are not listed on the lease. Even if s/he had previously said it was okay for these people to live in the apartment, unless it was in writing, the landlord has the right to ask them to leave. That is why it is so important to have everything in writing! If your name is the only one on the lease, then you are the only person responsible for the rent. That is a dangerous position in which to place yourself!
