- Your client wants to rescind the contract based on mutual mistake. What is the seller's strongest defense? Select one.
Answer: The "as is" clause in the contract effectively allocated the risk of unknown defects to your client.
A party cannot void a contract for mistake if they bore the risk of that mistake. An "as is" clause is a common way to allocate the risk of unknown defects to the buyer. By agreeing to this term, the buyer accepts the property in its current condition and assumes the risk that it may have hidden flaws. This is the seller's strongest argument against a claim of mutual mistake.
- A year later, the landowner discovers the error in the deed. What is the landowner's best remedy? Select one.
Answer: Reformation of the deed to reflect the boundary line at the oak tree.
Similar to a scrivener's error in a contract, when a deed contains a description that does not reflect the parties' actual agreement due to a mistake, the appropriate remedy is reformation. The court can correct the deed's legal description to conform to the parties' true intent, which was to set the boundary at the oak tree. Rescission would be too drastic, as it would undo the entire valid sale.
- Your client now wants to have the contract rescinded based on unilateral mistake. What is the city's strongest argument to enforce the contract? Select one.
Answer: Your client assumed the risk of any error by confirming the bid after being questioned.
When a party has an opportunity to discover a mistake but fails to investigate and instead confirms the contract terms, courts may find that the party assumed the risk of the mistake. Here, the city's inquiry gave the client a clear opportunity to verify its calculations, but the client chose to confirm without investigation. This assumption of risk defeats the unilateral mistake defense, making the contract enforceable despite the computational error.
- Is the enthusiast likely to succeed? Select one.
Answer: Yes, because the sale was based on a mutual mistake as to the authenticity of the wine.
This situation is a classic case of mutual mistake about a basic assumption—the authenticity of the product. Both parties believed they were contracting for a genuine 1982 vintage, but the subject matter was actually a counterfeit. This mistake about the wine's identity, not just its quality or value, was material and allows for rescission. While a breach of warranty claim (D) might also be viable under the UCC, mutual mistake is a fundamental contract defense that provides a strong basis for undoing the transaction.
- Will the collector's suit for rescission likely succeed? Select one.
Answer: No, because the parties were consciously ignorant of the crate's contents and allocated the risk to the collector.
A party bears the risk of a mistake when they are aware at the time of contracting that they have only limited knowledge of the facts but treat that limited knowledge as sufficient. This is the doctrine of "conscious ignorance." Here, both parties knew they did not know the contents of the crate. The auctioneer's statement explicitly framed the transaction as a gamble, thereby allocating the risk of the contents being valueless to the buyer. Therefore, rescission for mistake is not available.
- What is the buyer's most appropriate remedy to obtain the property at 123 Oak Street? Select one.
Answer: Reformation of the written contract to reflect the parties' true agreement.
When a written agreement fails to express the actual agreement of the parties because of a mistake in drafting (a scrivener's error), the proper remedy is reformation. Reformation corrects the written document to conform to the parties' original intent. Here, both parties intended the contract to be for 123 Oak Street. Reformation will allow the court to enforce the deal as it was actually made.
- Is the farmer likely to succeed in voiding the contract? Select one.
Answer: Yes, because the developer knew of the farmer's unilateral mistake about a basic assumption and failed to correct it.
This is a case of unilateral mistake where the contract is voidable. The farmer was mistaken about a basic assumption (the size of the land), and this mistake has a material effect. The contract is voidable because the non-mistaken party, the developer, knew of the farmer's mistake and remained silent to take advantage of it. While parties are not always required to disclose information, one cannot knowingly exploit another's material mistake.
- Can the graduate rescind the employment contract based on her mistake? Select one.
Answer: No, because her unilateral mistake was not known to the firm and enforcement is not unconscionable.
This question tests your understanding of unilateral mistake in contract formation. When one party makes a mistake that the other party doesn't know about, the general rule is that the contract remains enforceable unless specific exceptions apply.
Option A is correct because the graduate's misreading of the salary constitutes a unilateral mistake — only she was mistaken about the terms. The firm had no reason to know of her error and acted in good faith. For a unilateral mistake to void a contract, it must either be known to the other party, or enforcement must be unconscionable (extremely unfair). Here, neither condition is met. The firm offered exactly what they intended, and enforcing the $90,000 salary isn't unconscionable.
Option B is wrong because subjective intent ("would not have accepted") alone doesn't void a contract for unilateral mistake. The law requires objective manifestations of assent, and she objectively accepted the written offer.
Option C misapplies the "meeting of the minds" concept. While salary is indeed material, there was actually a meeting of the minds regarding the objective terms. The firm intended $90,000 and wrote $90,000; the graduate accepted that written offer. Her subjective misunderstanding doesn't negate the objective agreement.
Option D incorrectly invokes the parol evidence rule, which prevents contradicting written contracts with prior oral statements. That's not the issue here — this is purely about mistake in contract formation.
Remember: unilateral mistakes rarely void contracts unless the other party knew of the mistake or enforcement would be unconscionable. Focus on what each party objectively communicated, not their subjective understanding.
- Which legal doctrine provides the strongest basis for the person to cancel the contract and obtain a refund? Select one.
Answer: Frustration of purpose, because a subsequent event completely destroyed the value of the contract for the buyer.
This is a classic example of frustration of purpose. The doctrine of mistake does not apply because, at the time of contracting, both parties correctly believed the parade was scheduled to occur. The mistake doctrine applies to errors regarding an existing fact. Frustration of purpose applies when a later, unforeseen event, which was a basic assumption of the contract, completely or almost completely destroys the principal purpose of the contract for one party. Here, the cancellation of the parade frustrated the buyer's entire reason for booking the room.
- Is the farmer likely to succeed in rescinding the contract? Select one.
Answer: No, because the mistake related to a future event and the land's market value, not an existing fact.
The doctrine of mistake applies to a mistaken belief about an existing fact at the time the contract is made. It does not apply to predictions or judgments about future events or market conditions. Here, both parties' beliefs about the land's value were based on existing facts; the subsequent announcement was a future event that changed the land's value. This is not a mistake that would allow for rescission.
- Is the new company likely to succeed in having the contract rescinded? Select one.
Answer: Yes, because the significant price discrepancy gave the general contractor reason to know of the company's unilateral mistake.
A contract is voidable due to unilateral mistake if the non-mistaken party had reason to know of the other party's mistake. Here, the bid of $290,000 was so much lower than the other bids (all clustered around $450,000-$480,000) that the general contractor had reason to know a mistake had likely been made. Despite this, the contractor accepted without inquiry. This makes the contract voidable by the mistaken party.
- Is the homeowner's claim of mistake likely to succeed? Select one.
Answer: No, because this was a unilateral mistake, and the roofer had no reason to know it was a material term for the homeowner.
The homeowner's belief about the brand was a unilateral mistake. For a unilateral mistake to make a contract voidable, the other party must have had reason to know of the mistake. Here, the homeowner's comment was part of negotiations, but the final integrated contract specified a performance standard ("30-year architectural shingles"), not a brand. The roofer's failure to correct the homeowner's assumption is not enough to make the contract voidable, as the roofer fulfilled the terms of the written agreement and had no reason to know the homeowner's brand preference was a deal-breaking condition rather than just a casual comment.
- Can the buyer successfully rescind the contract based on mistake? Select one.
Answer: Yes, because the adequacy of the water service was a mutually mistaken assumption material to the contract.
This is a case of mutual mistake. Both parties believed the building had infrastructure suitable for a brewery, a basic assumption on which the contract was formed. The lack of adequate water service is a material mistake because it substantially frustrates the buyer's purpose, which was known to the seller, and requires a significant unforeseen expense. While there may also be a misrepresentation claim, mutual mistake provides a strong basis for rescission.
- Upon discovering the zoning change, can the buyer rescind the contract? Select one.
Answer: Yes, because there was a mutual mistake about an existing fact that was a basic assumption of the contract.
The contract is voidable based on mutual mistake. At the time of contracting, an existing fact (the legal zoning status of the property) was different from what both parties believed it to be. The permitted use of the land was a basic assumption on which the contract was made, and the mistake has a material effect on the buyer. Modern contract law generally allows rescission for mutual mistakes of law, treating them similarly to mistakes of fact.
- What is the inventor's best argument against the corporation's claim of mistake? Select one.
Answer: The mistake pertained to a future event—the court's ruling—not a fact existing at the time of the contract.
Contract mistake doctrine requires that the mistake concern a fact that existed at the time of contract formation. When parties are mistaken about something that hasn't happened yet, courts generally don't allow rescission based on mistake.
Here, both parties correctly understood the legal landscape when they signed the agreement—no existing patents covered the technology based on available information and prevailing legal interpretations. The court's subsequent broad reinterpretation of a competitor's patent was a future development that changed the legal consequences of their contract, not a pre-existing fact they misunderstood.
Answer A correctly identifies that the mistake pertained to a future event (the court's ruling) rather than an existing fact. The parties weren't wrong about what existed when they contracted; they simply couldn't predict how a court would later interpret patent law.
Answer B incorrectly focuses on risk allocation. While businesses do assume certain risks, this doesn't address whether a valid mistake occurred under contract law doctrine.
Answer C mischaracterizes the situation as a mistake of law versus fact. The parties weren't confused about legal principles—they correctly understood the law as it existed and was interpreted at the time.
Answer D is wrong because there was indeed a mistake in the parties' belief about infringement, just not the type that justifies rescission. Their belief proved incorrect when the court ruling made the technology infringing.
Remember: For contract mistake claims, timing matters crucially. The mistake must concern facts existing at contract formation, not future developments that change the contract's value or legality.
- What is the dealer's strongest defense against the collector's claim for rescission? Select one.
Answer: The mistake about the card's precise grade was not material to the agreed-upon exchange.
For a contract to be voidable due to mutual mistake, the mistake must have a material effect on the agreed-upon exchange. Materiality is a matter of degree. Here, the difference in value between what was expected ($5,000) and what was received ($4,800) is only 4%. A court would likely find this discrepancy to be immaterial and not a sufficient basis to undo the entire transaction, although the collector might have a claim for damages for breach of warranty.
- Is the accountant's misunderstanding of the lease terms a valid basis for voiding the contract? Select one.
Answer: No, because a party's failure to read a contract is a unilateral mistake that does not justify rescission.
The general rule is that a party is bound by the terms of a contract they sign, regardless of whether they have read it. The accountant's failure to read the lease constitutes a unilateral mistake. This type of mistake does not make a contract voidable, especially when the other party (the landlord) had no reason to know of the mistake and the term itself is standard in the industry and not unconscionable.
- Can the salvage company rescind the contract? Select one.
Answer: Yes, because the location of the ship was a basic assumption of the contract, and the mutual mistake makes performance radically different.
The contract is voidable due to mutual mistake. The location of the wreck was a basic assumption upon which the contract was founded. The mistake about this fact makes performance by the salvage company something radically different and more burdensome than what was contemplated. While salvage operations involve risk, a mistake of this magnitude about the fundamental facts underlying the performance goes beyond the risks typically assumed and justifies rescission.
- The homeowner learned of the stone's true identity and sued the gemologist to rescind the contract. What is the likely outcome of the lawsuit? Select one.
Answer: The homeowner will win, because there was a mutual mistake as to a basic assumption of the contract that had a material effect on the agreed exchange.
The contract is voidable based on mutual mistake. Both the homeowner (seller) and the gemologist (buyer) were mistaken about a basic assumption on which the contract was made—the identity of the stone (topaz vs. diamond). This mistake had a material effect on the agreed exchange, as the stone was worth vastly more than the contract price. The homeowner did not bear the risk of this mistake, as it was a shared error about the fundamental nature of the object, not merely its market value.
- What is the landlord's best legal recourse? Select one.
Answer: To sue for reformation of the lease to reflect the agreed-upon rent of $3,500.
When you encounter contract formation issues involving clerical errors, focus on whether the parties had a true meeting of the minds versus whether there was merely a transcription mistake. This question tests the remedy of reformation, which applies when parties agree on terms but the written contract contains an error.
Here, the landlord and tenant clearly agreed on $3,500 monthly rent during negotiations. The $2,500 figure resulted solely from the agent's typing error, not from any disagreement between the parties. This creates a situation where the written contract doesn't reflect their actual agreement, making reformation the appropriate remedy.
Answer A is correct because reformation allows courts to correct written contracts that don't accurately reflect the parties' true agreement due to mutual mistake or clerical error. Since both parties intended $3,500 but the document incorrectly states $2,500, a court can reform the lease to match their actual agreement.
Answer B is wrong because while contracts are generally enforced as written, reformation provides an exception when the writing doesn't reflect the true agreement due to error.
Answer C is incorrect because rescission would terminate the entire lease, which isn't necessary here since the parties want the lease—just with the correct rent amount.
Answer D fails because there was a meeting of the minds on price ($3,500). The error occurred in transcription, not in the parties' understanding of their agreement.
Study tip: Remember that reformation corrects writing errors when parties' true intent is clear, while rescission cancels contracts entirely. Look for situations where parties agreed but the document contains obvious mistakes.
