Madeline Castellotti was the sole shareholder of Whole Pies, Inc., which owns Jon’s Pizzeria in New York City. Her other assets included an interest in a real estate partnership, a residence on Staten Island, and bank accounts. When Madeline’s son Peter was going through a divorce, Madeline wanted to prevent his wife from obtaining any of Madeline’s assets. She removed Peter from her will, leaving her daughter Lisa as the sole beneficiary. Lisa orally agreed to transfer half of the assets to Peter after the divorce. In reliance on that promise, Peter agreed to pay the property taxes for the estate. Madeline died and Peter paid the taxes, but Lisa reneged on the deal. Is there a legal theory on which a court might enforce Lisa’s promise?
