Patsy is a seventy-seven-year-old widow who lives quite comfortably on both her late husbands pension and her Social Security benefits. Recently, Patsy has become increasingly absent minded, and her family fears that she may be suffering from the early stages of Alzheimer's Disease. No physician has diagnosed her, however, and no court has ruled on Patsys legal competence. One day while she is out shopping, Patsy stops by a store having a sale on pianos and enters into a three-year installment contract to buy an antique piano for $7,400. When the piano arrives the next week, Patsy claims that she does not recall buying a piano and repeatedly asks the deliverymen why they are delivering a piano to her house. Patsy comes to you, her family attorney, and wants your advice regarding the enforceability of this contract. What do you tell her? Can she disaffirm this contract or is the contract enforceable?
