“An inequality of bargaining power may arise in a number of ways. As Boyle and Percy, Contracts: Cases and Commentaries(4th ed. 1989), note, at pp. 637-38:
[A person] may be intellectually weaker by reason of a disease of the mind, economically weaker or simply situationally weaker because of temporary circumstances. Alternatively, the “weakness” may arise out of a special relationship in which trust and confidence has been reposed in the other party. The comparative weakness or special relationship is, in every case, a fact to be proven.”
