Rectification is an equitable remedy through which the court can rectify, or correct, a mistake in a written contract. This chapter examines two principal forms of rectification: common mistake rectification and unilateral mistake rectification. Rectification for common mistake arises where both parties make the same mistake. This is the better-established form of rectification. However, in some circumstances rectification for unilateral mistake will be granted in situations where only one party is mistaken but the other party has acted unconscionably or dishonestly. A party seeking rectification will need convincing proof that a mistake has been made before the court will contemplate altering the language chosen in a formal, written document.
