After Lisa built a church building on land that she owned, she told the Providence Church that they could use the building and the land for church purposes. The Providence Church held worship services there until Lisa died 45 years later, devising her entire estate to Jenny. Lisa’s son Andrew, however, believed that he was entitled to the land as Lisa’s sole heir, and Andrew repeatedly wrote to the Providence Church demanding that they stop using the property. The Providence Church ignored the letters and continued holding its worship services there for another 25 years. Who is the rightful owner of the land?
