My boyfriend’s father is a Landlord and is wanting to meet with us about renting one of his homes. He stated that he does not want my boyfriend signing the lease because he’s not going to sue his son. If his father is thinking he’s going to sue me one day, and keeping his son off the lease for that reason, is that legal? Is he allowed to rent to two people, but only let one sign the lease, and let his son off the lease, but still live there and not be legally responsible for anything?
