In the Law of Contract the phrase “mistake” & “Misrepresentation” is applied when one or both parties of a contract act under a false or mistaken understanding.
Mistake can be defined by Pendleton , Vickery (1998), [1] as; ➢ A misunderstanding regarding a fact, causing one or more parties to hold disagreeing beliefs about the foundation of a contract.
