Arthur and Celia, brother and sister, both of legal age, inherited Goodacre, their childhood home, from their father. They thereby became tenants in common. Goodacre had never been used as anything except a residence. Arthur had been residing on Goodacre with his father at the time his father died. Celia had been residing in a distant city. After their father's funeral, Arthur continued to live on Goodacre, but Celia returned to her own residence. There was no discussion between Arthur and Celia concerning their common ownership, nor had there ever been any administration of their father's estate. Arthur paid all taxes, insurance, and other carrying charges on Goodacre. He paid no rent or other compensation to Celia, nor did Celia request any such payment. Thirty years later, a series of disputes arose between Arthur and Celia for the first time concerning their respective rights to Goodacre. The jurisdiction where the land is located recognizes the usual common law types of cotenancies, and there is no applicable legislation on the subject. If Arthur claims the entire title to Goodacre in fee simple and brings an action against Celia to quiet title in himself, and if the state where the land is located has an ordinary 20-year adverse possession statute, the decision should be for 
Arthur, because during the past 30 years Arthur has exercised the type of occupancy ordinarily considered sufficient to satisfy the adverse possession requirements.  Arthur, because the acts of the parties indicate Celia's intention to renounce her right to inheritance.  Celia, because there is no evidence that Arthur has performed sufficient acts to constitute her ouster.  Celia, because one cotenant cannot acquire title by adverse possession against another.
