Bonney McWilliam’s father deeded a house in Norfolk County, Massachusetts, to Bonney and her daughter, Mechelle. Each owned a one-half interest. Described as “an emotionally troubled teenager,” Mechelle had a history of substance abuse and a fractured relationship with her mother. At age sixteen, in the presence of her mother and her mother’s attorney, Mechelle signed a deed transferring her interest in the house to Bonney. Later, still at odds with her mother, Mechelle learned that she did not have a right to enter the house to retrieve her belongings. Bonney claimed sole ownership. Mechelle filed a lawsuit in a Massachusetts state court against her mother to declare the deed void. Could the transfer of Mechelle’s interest be disaffirmed? Explain. [McWilliam v. McWilliam, 46 N.E.3d 598 (Mass.App.Ct. 2016)] (See Contractual Capacity.
