Contracts exam concept

Void vs. voidable vs. unenforceable contracts

Ask who can fix the problem. Nobody can ratify a truly void bargain. The protected party can affirm or avoid a voidable contract. A legal defense can block enforcement of an agreement that is otherwise recognizable. That one question about power separates three labels that exam distractors deliberately blur.

Last updated: August 1, 2026

What is the difference at a glance?

Short answer: Void means no legal effect and no ratification. Voidable means one protected party has the power to rescind or ratify. Unenforceable means a defense or unmet formality blocks a court remedy, with the Statute of Frauds as the familiar real estate example. Before using any status label, check whether a contract formed at all. Then identify the defect, whose protection it serves, whether affirmation is possible, what remedy is sought, and which document proves the answer.

Expected scored items
The current PSI broker outline assigns about 19 of 100 scored national items to Contracts

These labels are exam categories, not substitutes for legal advice. Courts classify actual disputes from the statute, public policy, contract language, capacity, authority, timing, requested remedy, and evidence. Illinois decisions also caution that a statutory violation does not automatically invalidate an entire contract, and Statute of Frauds exceptions can depend on whether the claim seeks damages or equitable relief. Sources were reviewed through August 1, 2026.

What changes from one term to the next?

Terms
Void vs. voidable
Difference
A void bargain has no legal effect and cannot be ratified. A voidable contract can be avoided or ratified by the protected party.
Question cue
Nobody can cure versus one party can elect.
Terms
Void vs. unenforceable
Difference
Void concerns legal existence or effect. Unenforceable concerns whether a court will supply a remedy despite an otherwise recognizable agreement.
Question cue
No legal effect versus remedy blocked.
Terms
Voidable vs. unenforceable
Difference
Voidable gives a protected party a choice to affirm or avoid. Unenforceable gives a party a defense against judicial enforcement.
Question cue
Election after consent defect versus enforcement defense.
Terms
No contract vs. void contract
Difference
No contract means formation failed. Void means the apparent bargain is treated as having no legal effect because of its legal defect.
Question cue
Missing agreement element versus prohibited or invalid bargain.
Terms
Rescission vs. ratification
Difference
Rescission exercises the power to undo a voidable contract. Ratification affirms it and extinguishes that power.
Question cue
Reject and restore versus accept and continue.
Terms
Fraud in inducement vs. forgery
Difference
Fraudulent inducement can produce genuine but avoidable assent. A forged signature is not the purported signer's act and may mean that person never agreed at all.
Question cue
Deceived signature versus no authentic signature.
Terms
Oral contract vs. illegal contract
Difference
Oral form raises a Statute of Frauds question when a writing is required. Illegal purpose raises validity and public-policy questions.
Question cue
Formality defect versus unlawful object.
Terms
Statute of Frauds vs. statute of limitations
Difference
The Statute of Frauds asks whether specified agreements have sufficient written and signed evidence. A statute of limitations asks whether the claim was filed within the legal period.
Question cue
Proof form versus filing time.
Terms
Executed vs. enforceable
Difference
Executed means performance is complete. Enforceable means a court remedy is available. One label does not prove the other.
Question cue
Performance status versus remedy status.
Terms
Rescission vs. reformation
Difference
Rescission unwinds the agreement. Reformation corrects the writing to reflect the parties' proven actual agreement.
Question cue
Undo the deal versus correct the document.

How does the distinction change the answer?

Illegal intended use

Scenario: A seller and buyer sign an agreement whose required purpose is to operate an enterprise that state law expressly prohibits on the property.

  1. The problem is not merely an oral promise or delayed lawsuit.
  2. The bargain requires unlawful performance as its object.
  3. Neither party's later affirmation can make that required purpose lawful.

Answer: The clean exam classification is void because the agreement's required object is illegal.

Purchase agreement signed under actionable duress

Scenario: A buyer uses a wrongful threat that leaves the seller no reasonable alternative, and the threat causes the seller to sign. The seller promptly seeks to unwind the deal after becoming safe.

  1. A signed agreement appears to have formed.
  2. The consent defect protects the coerced seller.
  3. The seller, not the buyer who applied the pressure, holds the power to seek rescission.

Answer: The contract is voidable by the seller on the stated duress facts.

Fraud followed by continued performance

Scenario: A purchaser learns that the seller made a material fraudulent statement, yet knowingly continues the contract for months, accepts its benefits, and expressly confirms the closing date.

  1. Fraud can initially give the injured purchaser a power of avoidance.
  2. Ratification requires informed conduct after discovery and an ability to choose.
  3. Continued benefits, performance, and express confirmation can be evidence of affirmation.

Answer: The contract was voidable, but the facts support a ratification issue rather than automatic nullity.

Oral agreement to sell a parcel

Scenario: An owner orally agrees to sell an identified Illinois parcel for a stated price, but no memorandum or note is signed by the owner or an authorized signer.

  1. The subject is a sale of land.
  2. The Illinois Statute of Frauds calls for signed written evidence from the party to be charged.
  3. The defect concerns judicial enforcement and does not make the property's sale an illegal purpose.

Answer: The standard exam classification is unenforceable against the owner under the Statute of Frauds, subject to fact-specific exceptions.

Unsigned paper, attributable electronic acceptance

Scenario: The parties agreed to transact electronically. An email containing the essential sale terms is electronically signed by the seller, its attribution is established, and the record can be retained accurately.

  1. Illinois law does not deny a record legal effect solely because it is electronic.
  2. The parties agreed to use electronic means, and the signature is the seller's act.
  3. Electronic form can satisfy writing and signature requirements if all other substantive requirements exist.

Answer: Do not classify the agreement as unenforceable merely because no paper was signed.

Changed offer never accepted

Scenario: A seller offers to close on October 1. The buyer signs but changes closing to November 1. The seller never accepts the changed date.

  1. Changing the closing date creates a counteroffer rather than mirror-image acceptance.
  2. The original offer was rejected by the counteroffer under the usual exam rule.
  3. No later acceptance forms the proposed November contract.

Answer: No contract formed; void, voidable, and unenforceable are not the best first labels.

The S-T-A-T-U-S decision test

  1. Start with formation: find offer, acceptance, consideration, objective assent, definite terms, capacity, and authority.
  2. Tag the defect: illegal object, prohibited policy, fraud, duress, minority, mistake, missing writing, late claim, forgery, or no acceptance.
  3. Ask who holds the power: nobody, the protected party, the party asserting an enforcement defense, or the court under the governing law.
  4. Test cure and election: ratification, disaffirmance, rescission, reformation, new agreement, electronic signature, written memorandum, or statutory exception.
  5. Use the right time: formation date, discovery of defect, end of incapacity, prompt rescission, full or part performance, and limitations period.
  6. Separate status from performance: valid, void, voidable, and unenforceable answer a different question from executed, executory, breached, terminated, or discharged.

Where do similar terms create traps?

Trap
Calling every defective agreement void
Correction
Name the defect first. Consent defects often make a contract voidable, and formality defenses often make it unenforceable.
Trap
Calling a covered oral land agreement illegal
Correction
The usual Statute of Frauds issue is enforceability, not an unlawful purpose.
Trap
Letting either party void a voidable contract
Correction
The power belongs to the party the doctrine protects, not automatically to the party who caused fraud, duress, or another defect.
Trap
Assuming a voidable contract disappears automatically
Correction
It remains capable of effect until the protected party avoids it and can be ratified on qualifying facts.
Trap
Trying to ratify a void bargain
Correction
A truly void agreement cannot be affirmed into validity; a new lawful agreement is required.
Trap
Treating hard bargaining as duress
Correction
Look for a wrongful threat, lack of reasonable alternative, loss of free choice, and causation.
Trap
Assuming every mistake cancels the contract
Correction
The mistake must satisfy legal requirements such as materiality, basic assumption, adverse effect, and appropriate risk allocation.
Trap
Treating every minor's contract as void
Correction
The standard exam treatment is usually voidable by the protected minor, with important rules for necessities, emancipation, disaffirmance, and ratification.
Trap
Assuming every statutory violation voids the whole agreement
Correction
Illinois authority calls for attention to statutory language, public policy, seriousness, expectations, forfeiture, connection, and possible severability.
Trap
Assuming an electronic signature cures everything
Correction
Electronic form can satisfy a formality, but it does not prove assent, authority, capacity, legal purpose, or complete terms.
Trap
Using executed as a synonym for valid
Correction
Executed describes completed performance. Valid describes legal sufficiency, and the two classifications are independent.
Trap
Giving the broker the final legal conclusion
Correction
A licensee should recognize the status issue, preserve the documents, avoid unauthorized legal advice, and refer the parties to counsel for case-specific enforcement decisions.

Can you separate the terms in a new fact pattern?

These questions are original study items aligned to the published outline. They are not copied, recalled, or predicted PSI questions.

1. Which statement best describes a void contract?

  1. It has no legal effect and cannot be ratified
  2. Only the protected party can rescind it
  3. It is enforceable after any oral promise
  4. It means performance is incomplete
Show answer and explanation

Answer: It has no legal effect and cannot be ratified

Void status means the apparent bargain cannot gain legal effect through a party's later affirmation.

2. A purchaser signed because of actionable fraud and later discovers the truth. Which classification is generally best before the purchaser elects a remedy?

  1. Voidable
  2. Automatically void
  3. Executed
  4. Unilateral
Show answer and explanation

Answer: Voidable

Fraudulent inducement commonly gives the injured party a power to rescind or ratify.

3. Which classification usually fits a covered Illinois oral land-sale agreement with no sufficient signed memorandum?

  1. Unenforceable
  2. Void for illegal purpose
  3. Executed
  4. Ratified automatically
Show answer and explanation

Answer: Unenforceable

The Illinois Statute of Frauds supplies an enforcement defense rather than making a lawful sale purpose illegal.

4. A buyer changes a material term in the seller's offer, and the seller never accepts the change. What is the best analysis?

  1. No contract formed because the response was a counteroffer
  2. The original contract is voidable by either party
  3. The contract is executed
  4. The Statute of Frauds automatically supplies acceptance
Show answer and explanation

Answer: No contract formed because the response was a counteroffer

Formation fails before contract-status analysis because no mirror-image acceptance or acceptance of the counteroffer occurred.

5. Which act most strongly supports ratification of a voidable contract?

  1. The protected party knowingly affirms it after the defect ends
  2. The wrongdoer declares it valid
  3. A broker labels it executed
  4. The illegal purpose continues
Show answer and explanation

Answer: The protected party knowingly affirms it after the defect ends

Ratification requires an informed election by the party who holds the power of avoidance on qualifying facts.

Where do these ideas appear on the outline?

Topic
Formation before status
What to know
Offer, acceptance, counteroffer, communication, mutual assent, consideration, definite terms, capacity, authority, lawful object, signature, and no contract
Best exam move
Ask whether an agreement formed before deciding whether a formed contract is void, voidable, or unenforceable.
Topic
No contract
What to know
Invitation to negotiate, expired offer, revocation, rejection, material change, no acceptance, indefinite property, missing assent, illusory promise, lack of consideration, no authority, forgery, and condition to formation
Best exam move
If an essential formation element never existed, say no contract rather than inventing a later enforcement defect.
Topic
Valid contract
What to know
Competent parties, mutual assent, offer, acceptance, consideration, lawful purpose, definite terms, authority, required writing, signature, enforceability, and remedies
Best exam move
A valid contract satisfies formation and legal requirements, even when performance remains due.
Topic
Void agreement
What to know
No legal effect, void ab initio, treated as never existing, illegal object, prohibited bargain, fundamental public policy, incurable authority restriction, no ratification, no waiver of defect, and new lawful agreement
Best exam move
Choose void when the bargain cannot acquire legal effect through either party's election.
Topic
Illegality and public policy
What to know
Unlawful performance, criminal purpose, discriminatory covenant, statutory prohibition, regulatory violation, public policy, justified expectations, forfeiture, seriousness, connection to misconduct, severability, and no automatic rule
Best exam move
Use the simple illegal-object rule for a clean exam fact, but do not assume every technical violation voids the whole agreement.
Topic
Voidable contract
What to know
Effective unless avoided, protected party, power of avoidance, election, fraud, material misrepresentation, duress, undue influence, minority, impaired capacity, mistake, unconscionability, rescission, restitution, ratification, and waiver
Best exam move
Identify which party the doctrine protects and whether that party chose rescission or affirmation.
Topic
Fraud and misrepresentation
What to know
False material fact, knowledge, intent, justified reliance, injury, concealment, duty to disclose, inducement, prompt rescission, tender back, damages, ratification, and evidence
Best exam move
Fraud in the inducement commonly makes the agreement voidable by the injured party rather than automatically void for everyone.
Topic
Duress and undue influence
What to know
Wrongful threat, loss of free will, no reasonable alternative, causation, vulnerability, trust, domination, unfair persuasion, protected party, rescission, prompt election, benefits, and independent advice
Best exam move
Economic pressure or a hard bargain alone does not establish duress; look for the wrongful pressure that produced assent.
Topic
Minority and capacity
What to know
Minor, emancipation, necessities, disaffirmance, majority, ratification, mental capacity, guardianship, intoxication, understanding, transaction nature, consequences, lucid interval, knowledge, and proof
Best exam move
Do not call every capacity issue void. The standard exam answer for a protected minor's nonessential bargain is usually voidable by the minor.
Topic
Mistake
What to know
Mutual mistake, unilateral mistake, material fact, basic assumption, adverse effect, risk allocation, drafting error, legal description, rescission, reformation, voidable status, and evidence of true agreement
Best exam move
A material mutual mistake can make a contract voidable and support rescission or reformation, depending on proof and risk allocation.
Topic
Ratification
What to know
Express affirmation, implied conduct, full knowledge, defect ended, capacity restored, acceptance of benefits, continued performance, unreasonable delay, waiver, protected party, and no wrongdoer election
Best exam move
Ratification belongs in the voidable column because it removes the power of avoidance; it cannot validate a void bargain.
Topic
Rescission and restitution
What to know
Unmaking contract, prompt notice, election, return of benefits, tender, status quo, cancellation, restitution, fraud, duress, mistake, mutual rescission, equitable relief, and no windfall
Best exam move
Rescission seeks to undo the transaction and restore positions, while damages seek compensation for loss.
Topic
Unenforceable agreement
What to know
Recognizable agreement, legal defense, judicial remedy blocked, formality, Statute of Frauds, limitations period, discharged duty, evidence rule, public policy, defense asserted, and no automatic illegality
Best exam move
Choose unenforceable when the defect concerns the ability to obtain a court remedy rather than one party's election to avoid.
Topic
Illinois Statute of Frauds
What to know
Sale of land, tenement, hereditament, interest in land, longer than one year, memorandum, note, writing, material terms, party to be charged, signature, authorized person, written authority, action barred, and exception
Best exam move
A covered oral land agreement is the classic unenforceable answer, not the classic illegal or void answer.
Topic
Sufficient memorandum
What to know
Identity of parties, property description, price, essential terms, signature, party to be charged, multiple writings, reference, authority, email, text, electronic record, attribution, and retained record
Best exam move
A formal paper contract is not the only possible memorandum, but the combined evidence must satisfy the governing writing and signature requirements.
Topic
Electronic records and signatures
What to know
Illinois UETA, agreement to transact electronically, record, signature, legal effect, enforceability, attribution, security procedure, context, surrounding circumstances, retention, accuracy, delivery, and other substantive law
Best exam move
Electronic form can satisfy writing and signature formalities, but it cannot supply missing assent, authority, legal purpose, or definite terms.
Topic
Limitations and remedy timing
What to know
Accrual, written contract, unwritten contract, ten years, five years, demand, tolling, revival, counterclaim, repose, defense, current statute, and no universal deadline
Best exam move
A limitations issue concerns whether a claim can still be enforced in court, not whether the original subject matter was illegal.
Topic
Independent classifications
What to know
Executed, executory, bilateral, unilateral, express, implied, assignable, nonassignable, discharged, breached, terminated, expired, enforceable, and status
Best exam move
A contract can be valid and executory at the same time; performance labels do not replace validity labels.

Questions students ask about Void vs. Voidable vs. Unenforceable Contracts

What is the difference between void, voidable, and unenforceable contracts?

A void agreement has no legal effect and cannot be ratified. A voidable contract can be avoided by the party whom the law protects, but it remains capable of ratification. An unenforceable agreement may be recognizable as an agreement, yet a defense or missing legal formality prevents a court from enforcing it. The exam expects the defect, protected party, and remedy to match the label.

Is a void contract the same as no contract?

They lead to a similar practical result but describe different analysis. No contract means formation failed, perhaps because there was no acceptance, consideration, authority, or sufficiently definite agreement. Void usually means the apparent bargain has no legal effect because its object or required legal foundation is invalid. On a careful exam question, identify the failed formation element before selecting a status label.

What is a common example of a void agreement?

The standard exam example is an agreement whose required object is illegal, such as a bargain to use property for an unlawful enterprise. Still, a statutory violation does not automatically make every related agreement void. The statute, public policy, parties' conduct, and whether an offending term can be separated may require legal analysis.

What is a common example of a voidable contract?

A contract induced by actionable fraud or duress is commonly voidable at the election of the injured party. Certain contracts involving a minor, impaired capacity, undue influence, or material mistake can also be voidable. The protected party may seek rescission or, after the defect ends and material facts are known, may ratify the agreement.

What is a common example of an unenforceable real estate contract?

A covered oral agreement for the sale of land that lacks a signed writing is the classic example. Illinois's Statute of Frauds generally bars an action on a contract for the sale of land or specified longer interests unless a memorandum or note is written and signed by the party to be charged or a person lawfully authorized in writing.

Is an oral real estate contract always void?

No. For exam purposes, a covered oral land agreement that fails the Statute of Frauds is generally classified as unenforceable, not void or illegal. Whether a particular writing is sufficient, an exception applies, or an equitable remedy remains available is fact-specific and should not be assumed from the word oral alone.

Can a voidable contract become enforceable?

Yes. The protected party may ratify a voidable contract expressly or through conduct that clearly affirms it after gaining the ability and necessary knowledge to choose. Continuing to accept benefits can matter. The wrongdoer cannot force ratification, and Illinois decisions stress prompt action when a party seeks rescission after discovering fraud or misrepresentation.

Can a void contract be ratified?

No. Ratification can extinguish a protected party's power to avoid a voidable contract, but it cannot breathe legal effect into a truly void agreement. If the parties want a lawful relationship after a void bargain, they generally need a new agreement that satisfies formation, legality, authority, and required formalities.

Can an electronic signature satisfy the Illinois Statute of Frauds?

Generally yes when the Illinois Uniform Electronic Transactions Act applies, the parties agreed to transact electronically, and the electronic signature is attributable to the signer. An electronic record cannot be denied effect solely because of its form. It still must contain the necessary terms, reflect the person's act, and satisfy other substantive law.

Are these official PSI exam questions?

No. They are original questions aligned to the national Contracts outline effective June 24, 2026. The current PSI bulletin, Illinois Statute of Frauds, Uniform Electronic Transactions Act, limitations statutes, and official Illinois court opinions were reviewed through August 1, 2026.
