Please help with my homework question
Lisa and Danny are neighbors that live on Guerrero Street. Fifteen years ago Lisa built a gazebo. She frequently used the gazebo, but she was not aware that actually the gazebo was on property belonging to Danny. A month after the gazebo was built Lisa built a fence between her and Danny's yard, and the gazebo was on Lisa's side of the fence. Fifteen years later, Danny has a survey done, and he discovers that the gazebo is on his land. Danny brings a suit to evict Lisa from the land. Does Lisa have a defense? Assume that the state in question has an adverse possession period of ten years.
