Mutual Assent
You agreed. But did you REALLY agree?
The Used Car
Seller says: “Never been in an accident”
Seller knows it was nearly totaled last year
Fraud
The Boss
“Sign this agreement or I’ll make sure you never work in this injury again”
Duress
The Collectible
Buyer and seller both believe a signed Taylor Swift poster is authentic
It isn’t
Mutual Mistake
The Terms and Conditions
I have read and agree to all 47 pages
Unconscionability
Did the parties genuinely assent to this deal?
Mutual Assent
The parties have the same understanding of the terms and conditions of the contract
But apparent agreement can be undermined by:
Fraud;
Misrepresentation;
Mistake;
Duress;
Undue influence; or
Unconscionability
Saying “yes” isn’t always the end of the analysis
Where are we?
The contract formation checklist:
Offer
Acceptance
Consideration
Mutual Assent (We are here)
Capacity
Legality
Proper form, when required
Today’s focus: What could make an apparent agreement legally defective?
Fraud
Fraud = Intentional Deception
Ask
Was there a misstatement of fact?
Was the fact material?
Did the speaker know it was false?
Was there an intent to deceive?
Did the other party rely on it?
Did the reliance cause damage?
Don’t stop at: “But they lied!”
Build the Fraud Case
Seller: “This car has never been in an accident.”
Reality: Seller knows it was previously totalled
Element | Evidence |
Misstatement | “Never been in an accident” |
Material | Accident history affects the transaction |
Knowledge | Seller knows the truth |
Intent | Seller wants buyer to believe it |
Reliance | Buyer purchases because of it |
Damage | Buyer overpays |
Fact, Opinion or Puffery
Which could support fraud?
A. “This is the best car you’ll ever own
Puffery
B. “This car has 42,000 original miles”
Fact
C. “You’re going to LOVE this car”
Opinion/Puffery
D. “The engine was replaced last month”
Fact
E. “This car is basically indestructible”
Puffery
Materiality
Does the fact actually matter?
A material fact is important enough to affect the decision to enter the contract
Example:
“The house has never flooded” (material)
vs.
“This is the cutest house in the neighborhood”
Or
“The roof was replaced last year” (material)
vs.
“You’re going to love living here”
Lawyer question: Would this information matter to the deal?
Reliance Matters
Seller falsely says: “The laptop has never been repaired”
Buyer responds: “I don’t care. I’m stripping it for parts anyways”
Buyer purchases it
Fraud?
What element might be missing?
Reliance
A lie alone doesn’t complete the analysis
Misrepresentation
A false statement of material fact made without an intent to deceive
Same bad information but a different state of mind
Fraud | Misrepresentation |
Statement is false | Statement is false |
Speaker knows it | Speaker believes it is true |
Intent to deceive | No intent to deceive |
Fraud or Misrepresentation? Facebook Marketplace Edition
Seller: “2025 MacBook Pro - 1 TB Storage”
Scenario A:
Seller knows it has only 512 GB
Fraud
Scenario B:
Seller honestly believes it has 1 TB
Misrepresentation
What changed?
The seller’s knowledge and intent
What about silence?
Do you have to tell the other party everything?
Generally: Silence alone does not necessarily equal fraud
But circumstances may create a Duty to Disclose
One important situation involves a fiduciary relationship:
A relationship involving special trust, confidence, or responsibility
Examples may include:
Attorney → Client
Trustee → Beneficiary
Agent → Principal
Sometimes saying nothing says plenty
Rescission
Think: CMD + Z for Contracts
Rescission seeks to:
Undo the contract
And, as much as possible,
Return the parties to their pre-contract positions
“Let’s pretend this deal never happened”
Mistake
An erroneous belief concerning a fact relevant to the agreement
Two possibilities:
Mutual Mistake—Both parties are wrong
Unilateral Mistake—One party is wrong
Same word. Very different analysis
Mutual Mistake
Everybody got it wrong
Seller offers a guitar allegedly signed by Taylor Swift
Seller: “It’s authentic”
Buyer: “I agree”
Price: $5,000
Later…the signature is fake
Neither party knew
What exactly did the parties think they were bargaining for?
Mistake or Bad Prediction
These are NOT the same
Existing Fact: “We both believe this diamond is genuine”
Potential mistake
Future Prediction: “We both believe this collectible will be worth $50,000 someday”
Bad prediction necessarily mistake
Contract law generally doesn’t guarantee that your deal will age well
Unilateral Mistake
One party got it wrong
A contractor prepares a bid:
Materials: $40,000
Labor: $30,000
Profit: $10,000
Intended Bid: $80,000
But accidentally submits: $8,000
Owner: "“ACCEPTED!”
Is the contractor stuck with it?
Key Questions:
How serious was the mistake
Did the other party know or have reason to know?
What would enforcement mean?
Duress
When “Yes” isn’t voluntary
Duress involves improper threats or coercion that deprive a party or meaningful free choice
Compare:
“This offer expires at 5:00”
“Sign this or I’ll hurt you” (Duress)
Pressure automatically duress
Hard Bargaining or Duress
You be the Lawyer:
1. “My offer expires at 5”
Hard bargaining
2. “Take $3,000 or I’m selling it to someone else”
Hard bargaining
3. “Sign this or I’ll destroy your reputation”
Duress
4. “Sign this or your family will regret it”
Duress
5. “I know you’re desperate for the money. This is my final offer”
Either way
Undue Influence
Not every threat looks like a threat
Undue Influence: involves improper persuasion, often where one party is particularly susceptible to another’s influence
Think: Trust, power, vulnerability, improper persuasion
Potential contexts:
Caregiver/dependent person
Adviser/client
Family member/vulnerable relative
Duress:
“Do this or else”
Undue influence:
“Trust me. You know I know what’s best for you
Duress or Undue Influence
Scenario A
“Transfer the property or else”
Duress
Scenario B
An elderly person depends completely on a relative for daily care. The relative repeatedly pressures the person to transfer property to them
Undue Influence
Both affect free choice
The mechanism is different
Unconscionability
The “Come on, seriously?” Doctrine
A contract or provision may be challenged when the contracting process or terms are extremely unfair or oppressive
But…Bad deal unconscionable deal
Courts generally do not rescue parties simply because:
They paid too much
They changed their mind
They didn’t negotiate well
They later regretted the deal
Something more is required
Two kinds of Unconscionability
Easy memory trick:
Procedural = PROCESS
Substantive =SUBSTANCE
Procedural | Substantive |
Problem with the PROCESS | Problem with the SUBSTANCE |
How was the agreement obtained? | What do the terms actually say? |
Hidden terms | Oppressive provisions |
Lack of meaningful choice | Extreme imbalance |
Unequal bargaining circumstances | Harsh one-sided obligations |
The 3:00 a.m Apartment
A student desperately needs housing before classes begin.
The landlord presents a lengthy, non-negotiable lease.
Buried on page 19: “Landlord shall never be liable for any injury occurring on the premises for any reason whatsoever.”
Landlord says: “Sign it now or I'm giving the apartment to the next person.”
What do you see?
Procedural unconscionability?
Substantive unconscionability?
Both? Neither?
Contract you don’t Negotiate
Boilerplate: Standardized language used repeatedly in contracts
Adhesion Contract
A standardized contract generally drafted by the party with greater bargaining power and offered on a take-it-or-leave-it basis
You encounter them constantly:
Apps;
Leases;
Gym memberships;
Software;
Tickets;
Financing
Important: Standardized automatically enforceable
Overreaching
Taking unfair advantage of another party though excessive or improper conduct
Look at the whole transaction:
Bargaining power
Knowledge
Vulnerability
Hidden or confusing terms
Opportunity to understand the agreement
Meaningful alternatives
Ask again: How did we get to “yes”?
Installment Contracts
Buy now. Pay Later. Read carefully
An installment contract provides for payment or performance in multiple installments over time
Common examples:
Auto financing;
Phone financing;
Furniture;
Buy-now-pay-later purchases
Installment contracts are not inherently problematic
But examine:
Fees, interest, default provisions, remedies, disclosures
Especially when considering claims of overreaching or unconscionability

MISREPRESENTATION
Wrong about an existing fact?
MISTAKE
Both → Mutual
One → Unilateral
Improper threat?
DURESS
Improper persuasion involving trust/power?
UNDUE INFLUENCE
Seriously unfair deal?
UNCONSIONABILITY
Process → Procedural
Terms → Substantive
