1. Jack and Jill, who are brother and sister, own Yellowacre in fee simple as joint tenants. For ten years Jill occupied Yellowacre and conducted a cosmetology business on the property. Jill never accounted to Jack for any of the income made from the cosmetology business. Jill did keep the property repaired and did pay solely all of the property taxes. In 2003 Jill died intestate survived by her only child, Helen. In 2004, Helen moved into the property and failed to pay any of the property taxes. The appropriate authority placed a tax lien on the property for unpaid taxes. In 2010 the government authority sold the property for the unpaid taxes to Billy. Thereafter, Jack instituted an action against Billy to quiet title and recover the possession of Yellowacre. Who owns Yellowacre?
