Question:

Joan, who is sixteen years old, moves out of her parents' home and signs a lone-year lease for an apartment at Kenwood Apartments. Joan's parents tell her that she can return to live with them at any time. Unable to pay the rent, Joan moves back to her parents' home two months later. Can Kenwood enforce the lease against Joan?
