Question: Mr. and Mrs. Conwell owned a lot next to Allen's property. They planted grass in an area that appeared to be between the two properties but actually belonged to Allen. After the statutory period had passed, the Conwells claimed that this was sufficient notice of their interest to obtain title by adverse possession. Allen brought suit to determine who has title to the land. Who is correct? (Conwell v. Allen, 21 Ariz. App. 383)
