Unilateral mistakes are said to occur when only one party is at mistake regarding the essential facts of a contract.
When there is a unilateral mistake, in what three types of situations may a contract not be enforced?
"Unilateral" means "one-sided". In the context of contract law, it means that one of the parties had an imperfect understanding of some provision in the contract at the time it was entered into. This can be either a mistake of fact or a mistake of law. Unilateral mistakes can be grounds for having a court nullify the contract. If widgets normally cost $100 and A agrees to sell them to B for $80, that's a bargain. If A instead contracts to sell them for $0.80 instead, that's clearly a mistake.
As with all legal questions the answer depends on the law of the state that has jurisdiction. Unilateral mistake is a contracts principle. If one party to a contract makes a mistake in understanding the contract or one of its terms, that party can ask a court to reform the contract but only if the mistake is of so great a consequence that to enforce it would be unconscionable. (See:Merchant of Venice, Shakespeare, Wm.); the mistake must relate to a material feature of the contract; the mistake must have been made notwithstanding reasonable care of the party making the mistake and the relief afforded must not seriously prejudice the other party, except for loss of the bargain. In other words, probably nothing. The above proofs are difficult, so relief is rarely given in unilateral mistake cases. And remember: A person who reads a contract and signs it without fully understanding it has a better chance of getting out of it than a person who signs it without reading it at all.
No, a unilateral mistake offers less protection to the mistaken party than a mutual mistake. If the mistake was based upon the mistaken party's own negligence, he will not be released from the contract. He will only be released if the mistake was so signifcant that the other party should have known it was a mistake, but attempted to snatch up the mistaken offer anyway. If the mistake results from an error in calculation rather than an error in business judgment, the mistaken party is more likely to be released.
There are three types of mistakes which the parties may made during contracting . They are . Common , Mutual and Unilateral mistake . When there is no consensus ad idem it will result in mistakes which are . Common and mutual mistake may be confuse , but mutual one is when both parties are mistaken as to the offer , acceptance of the contract both thought differently and believe the other consent to what he said , it base on the fundamental matter of the contract while common mistake is oppose to that one .

If a mistake is made in terms of identity (and it is material) or in terms of the subject matter of the contract then no contract is created. If a mistake is made about the existence of the subject matter or if the contract is frustrated the contract becomes impossible to perform.

A Sin Is Somthing That You Do On A Purpose Issue, A Mistake Is Like: You Fall On Something, Trip, Scratch, (Mistake) That Does Not Matter At All. And In contract law, a mistake is an erroneous belief, at contracting, that certain facts are true. It can be argued as a defence, and if raised successfully can lead to the agreement in question being found void ab initio or voidable, or alternatively an equitable remedy may be provided by the courts. Common law has identified three different types of mistake in contract: the 'unilateral mistake', the 'mutual mistake' and the 'common mistake'. It is important to note the distinction between the 'common mistake' and the 'mutual mistake'.Mistake can be- (1)Mistake of Law (2)Mistake of FactMistake of law: when a party enters into a contract, without the knowledge of the law in the country, the contract is affected by such mistakes but it is not void. A contract is not voidable because it was caused by a mistake as to any law in force in India. The reason here is that ignorance of law is not an excuse at all. However if a party is induced to enter into a contract by the mistake of law then such a contract is not valid. Illustration A and B make a contract grounded on the erroneous belief that a particular debt is barred by the Indian law of Limitation; the contract is not voidable.Mistake of Fact: Where both the parties into an agreement are under a mistake as to a matter of fact essential to the agreement, the agreement is void. Explanation: An erroneous opinion as to the value of the thing which forms the subject-matter of the agreement is not to be deemed a mistake as to a matter of fact.Illustration: (1) A agrees to buy a certain horse from B. It turns out that the horse was dead at the time of bargain, through neither party was aware of the fact. The agreement is void. (2) A, being entitled to an estate for the life to B, agrees to sell it to C. B was dead at the time of an agreement, but both the parties were ignorant of the fact. The agreement is void.

Basic Law 101: An advertised price is simply a solicitation for an offer, and is not a binding contract. If a shop advertises an item at a certain price and says it is a misprint, it is considered a unilateral mistake, and no court would hold them to the incorrect price.
