Can Marta obtain rescission of the contract based on undue influence? If the sale to Janis had been completed before her death, could Janis have obtained rescission based on undue influence? Explain.
Chelene had been a caregiver for Marta’s eighty-year-old mother, Janis, for nine years. Shortly before Janis passed away, Chelene convinced her to buy Chelene’s house for Marta. The elderly woman died before the papers were signed, however. Four months later, Marta used her inheritance to buy Chelene’s house without having it inspected. The house was built in the 1950s, and Chelene said it was in “perfect condition.” Nevertheless, one year after the purchase, the basement started leaking. Marta had the paneling removed from the basement walls and discovered that the walls were bowed inward and cracked. Marta then had a civil engineer inspect the basement walls, and he found that the cracks had been caulked and painted over before the paneling was installed. He concluded that the “wall failure” had existed “for at least thirty years” and that the basement walls were “structurally unsound.” Using the information presented in the chapter, answer the following questions.
