What is the meaning of mistake?

mistake is an error or misunderstanding. A contract is voidable if there is a mistake that is mutual, material, unintentional and free from negligence, such as both parties honestly contracting for a different lot in a subdivision (mistake of fact). Innocent mistakes seldom serve to void a contract. A party cannot claim "mistake" to get out of a contract on the basis that he or she did not read the contract he or she signed and was therefore mistaken as to its material terms; neither ignorance nor poor judgment is a mistake of fact. Nor can a party claim mistake in not knowing the legal consequences upon signing the contract (mistake of law). When there is an ambiguity known by one party who fails to explain the mistake to the innocent party, the innocent party's interpretation generally will prevail.
