This presentation will emphasis onseveral instances where courts will not obtrude a contract even though itsatisfies the basic contract facets of offer, acceptance and consideration. We’llhighlight the 3 “M’s”: mistake, misunderstanding and misrepresentation.

You are watching: Overestimating the value of an object is a mistake for which a court will normally provide relief.


“Mistake” deserve to be a defense againstenforcement that a contract once at least one party had actually a “belief that is no inaccord through the facts” with respect to crucial contract terms.<1>Mistake describes erroneous ideas of the parties the induced them to enterinto agreements, not mistakes the are relevant to the yes, really execution processof the agreement. For example, this defense is not appropriate to the scenariowhereby a party signed one agreement, thinking that she to be signing a creditcard receipt; though such an commitment could likewise be unenforceable as result of lackof precious assent.

Mistakes have the right to be mutual, definition thatboth parties mutual the exact same mistaken assumption, or deserve to be unilateral, meaningthat only one party to be under a false impression.

mutual mistake requires these fourcharacteristics:

(1) Themistake must have been make by both next at the time the contract to be made;

(2) Themistake should involve a straightforward assumption on i m sorry the contract to be made;

(3) Themistake have to materially affect the agreed top top exchange;and

(4) Thecontract is just voidable through a party who was adversely influenced by the mistake.<2>

A “basic assumption” is an assumptionrelating to a material reality of the agreement. The mistaken id must materiallyaffect the exchange to such a level that the imbalance is so great that itwould it is in unfair to enforce the contract.<3>For example, in Renner v. Kehl, twosellers determined to sell leases top top 2,000 acre of undeveloped land near Yuma,Arizona. The sellers to be approached by a buyer that wanted to lease the landto grow jojoba (ha-ho’ba), which is a shrub whose seeds develop a beneficial oil,on the land. The land showed up to it is in perfect for commercial jojoba production.Both parties thought that over there was enough water under the land that couldsustain advertisement jojoba production. After the contract was signed, theparties uncovered that there was not sufficient water come sustain this farmingactivities and so the buyer want to void the contract. The contract was heldto be voidable since both parties made the an easy assumption the there wouldbe adequate water come sustain production. The assumption materially affectedthe contract due to the fact that the parties only made the contract under the assumptionthat buyer might grow jojoba on the land.<4>

The last point detailed that just theadversely impacted party can avoid the contract. In the jojoba example, onlythe buyer can avoid the contract since he was the just party thatexperienced a detriment. The sellers obtained their money, but the the person who lives couldnot use the land.

One caveat come this dominion is the theadversely affected party have the right to only prevent the contract if that or she did not assumethe threat of make the mistake. Conversely, wherein it is obvious from thenature that the commitment that one next assuming a risk, the event of theanticipated danger does no constitute a “mistake” and also does not permit thecontract to it is in avoided. For example, if a land purchaser knows the the titleinsurance firm will not issue title insurance since it suspects some sortof title defect, the discovery of a defect later will no constitute a defenseof mistake. The purchaser knew of the risk and assumed it. Moreover, if the partiesknowingly get in into an agreement without all relevant information, they cannotavoid the contract merely because the relevant info turns out theprejudice among the parties. Because that example, if a seller who has not mined hisland agrees to sell it and later discovers the presence of beneficial mineralsbeneath the land, there will be no ground upon which come void the agreement. Theseller knew or should have known of his lack of knowledge and also his contractualagreement to offer the residential or commercial property assumes the threat that that was marketing somethingmore an important than met the eye.<5>.

Unilateralmistakes happen when just one party provides the mistake. The required elements forunilateral mistake room the same as common mistake, plus among the adhering to must exist:

(1) the impact of the mistake is together thatenforcement of the contract would be unconscionable; OR

(2) the non-mistaken party have to have had reasonto know of the various other party’s mistake; OR

(3) The mistake party’s mistake to be thefault the the various other party.”<6>

Unilateral mistakes frequently occur inconstruction instances where a bid was miscalculated.<7>

A contract may be “unconscionable” whenthe points of value exchanged are greatly disproportionate.<8>Whether terms space unconscionable is figured out on a fact-driven, case-by-case basis.For example, if a contractor submits a bid that is $50,000 much less than the wouldnormally have actually been since the contractor do a computation error, a court maydetermine this to it is in unconscionable, make the agreement unenforceable.However, if the bid is just $5,000 much less than what the would generally have been,this might not it is in unconscionable.<9>

Moreover, if the firm receiving thebids had actually reason to understand that the bid was unusually low because all the otherbids to be $50,000 much more than the contractor’s bid, this would militate stronglyin favor of a detect of unilateral mistake. In together a case, even a smallmistake would likely render the contract unenforceable. Recall that, where theother party knew that the mistake, unconscionability or extreme unfairness interms is no necessary.<10>


In part cases, mistakes about a contractterm outcomes in the parties being uncertain about their corresponding obligationsunder a contract. If this misunderstanding is serious sufficient so that theparties cannot reasonably be claimed to have had actually a “meeting that the minds,” thecontract will be unenforceable.<11>

One instance of this occurs as soon as eachparty has attached a different definition to the exact same term. Because that example, a famousBritish situation rendered a contract unenforceable once a vendor booked cargopassage on the dorn ship, yet that had actually the very same name together the one he expected tobook.<12>

Where parties have actually attached differentmeanings come one term, yet one party is unaware the the other party’s assumption,she will certainly be tied by that other party’s assumption.<13>For example, a buyer and a seller go into into an commitment for the exchange ofchickens. The the person who lives believes there is only one type of chickens called“broiling chickens.” The seller to know there are two species of chickens, “stewingchickens” and also “broiling chickens” and also knows that the buyer wants “broilingchickens.” In this case, the seller would have actually to administer “broiling chickens”to the buyer, even if the seller really expected to market stewing chickens.


Misrepresentation room incorrect orfraudulent assertions of fact throughout contract negotiation that cause relianceon the part of the various other party. The false statement must be knowingly andmust it is in important, or “material,” for this defense come apply.

A misrepresentation deserve to prevent theenforcement that the contract, make the contract voidable or administer grounds forreforming the contract, together fairness requires.<14>

The mere reality that a party is deceiveddoes not naturally void the contract as result of misrepresentation<3> In Phelps v. McQuade, forexample, the court held that overstating one’s wide range to secure a financingagreement to acquisition jewelry did not make the contract unenforceable. Thepurchaser’s wealth condition was not considered critical component of theagreement and also so lying about it was no a material misrepresentation.<4> In contrast, if a seller sell cubiczirconium, but represents it together diamond, there’s no concern that would qualifyas a product misrepresentation, together that falsehood goes directly to the natureof the item being sold.

Misrepresentations can likewise be innocent.That is, the party make the false assumption may not know that the assumptionis false. This will cause the contract to it is in unenforceable if the misrepresentationcauses a comprehensive variance between reality and what the various other partybelieved. For example, if throughout a real estate transaction negotiation, oneparty mistakenly over to represent the square clip on the thoreau by a smallamount, this is no necessarily grounds because that the contract to it is in avoided. If themisrepresentation was intentional, however, and also the various other party relied on thestatement, the is likely that the contract will certainly be unenforceable.

By allowing these defenses that mistake,misunderstanding and misrepresentation, contract regulation seeks to protect partiesfrom being bound through agreements the they never ever meant to it is in bound by. This areconsistent v the general contract legislation goals of protecting the reasonableexpectations of reasonable people.
