Consideration

Consideration is easier to see when you ask what each side bargained to give, do, promise, or refrain from doing. In a purchase contract, the exchanged promises usually do the work. Earnest money is important, but treating the deposit as the only consideration creates the wrong answer on many exam questions.

Last updated: August 1, 2026

What does this exam area cover?

Short answer: Consideration is a bargained-for exchange of promises, acts, or forbearance. A buyer's promise to pay and a seller's promise to convey ordinarily support a bilateral real estate contract. Consideration need not be equal in market value, but a mere gift promise, an entirely optional promise, a past act not exchanged for the promise, or performance of only a preexisting duty can fail. Earnest money is a deposit governed by the contract, not the sole test for consideration.

Best exam move
A bilateral contract needs real consideration supporting the obligations on both sides.
Topic
Separate earnest money
What to know
deposit, escrow, good faith, remedy fund, liquidated damages, due date, holder, return, forfeiture, and consideration

Best exam move
Legal sufficiency asks whether something of legal value was exchanged, not whether the deal was financially wise.
Topic
Treat adequacy carefully
What to know
market value, unequal bargain, bad deal, freedom of contract, gross inadequacy, shock conscience, unfairness, oppression, and unconscionability
Best exam move
Do not compare values routinely, but recognize exceptional gross inadequacy combined with inequitable circumstances.
Topic

What to know
one dollar, recital, token, actual payment, sham, option, deed, seal, exchange, and proof
Best exam move
A printed recital does not substitute for a real bargained exchange where one is required.
Topic
Support option contracts
What to know
option fee, keep offer open, fixed period, separate contract, exercise, purchase price, irrevocable offer, refundability, and deadline
Best exam move
Consideration supports the promise not to revoke; exercise follows the option's exact terms.

Which distinctions produce the most mistakes?

Terms
Consideration vs. earnest money
Difference
Consideration is the legal exchange supporting promises. Earnest money is a transaction deposit governed by the contract.
Question cue
Exchange versus deposit.
Terms
Benefit vs. legal detriment
Difference
A benefit accrues to one party. A legal detriment is an act, promise, responsibility, or forbearance undertaken by the other.
Question cue
Value received versus legal burden assumed.
Terms
Sufficiency vs. adequacy
Difference
Sufficiency asks whether legal value exists. Adequacy compares the economic value of the exchange.
Question cue
Something bargained versus equal bargain.
Terms
Promise vs. illusory promise
Difference
A promise commits the promisor. An illusory promise leaves performance completely optional.
Question cue
Real duty versus no duty.
Terms
Contingency vs. illusory discretion
Difference
A contingency ties performance to a defined event or standard. Illusory discretion lets one side walk away for any reason without constraint.
Question cue
Conditional duty versus optional promise.
Terms
Present exchange vs. past consideration
Difference
A present exchange is bargained for when promises are made. Past consideration was completed before the later promise and not induced by it.
Question cue
In exchange now versus already done.
Terms
New consideration vs. preexisting duty
Difference
New consideration adds or changes a legal obligation. A preexisting duty merely repeats what is already owed.
Question cue
Fresh burden versus same duty.
Terms
No consideration vs. failure of consideration
Difference
No consideration means the exchange was absent at formation. Failure of consideration concerns promised performance that later did not occur.
Question cue
Formation defect versus performance failure.
Terms
Option consideration vs. purchase price
Difference
Option consideration buys the right to decide during the option period. Purchase price is paid for the property under the exercised sale agreement.
Question cue
Right to choose versus property price.
Terms
Forbearance vs. waiver
Difference
Forbearance is refraining from exercising a right and can be promised as consideration. Waiver is intentional relinquishment of a known right and has its own rules.
Question cue
Promised restraint versus surrendered right.
Terms
Consideration vs. mutual assent
Difference
Consideration supplies the exchange. Mutual assent supplies objective agreement to the terms.
Question cue
Why promises bind versus what was agreed.
Terms
Consideration vs. motive
Difference
Consideration is what was bargained for. Motive is a party's personal reason for making the deal.
Question cue
Exchange term versus private purpose.

The V-A-L-U-E check

  1. Verify the bargain: identify what each promise sought and what the other side gave or promised in return.
  2. Assign legal value: classify each item as a promise, act, forbearance, benefit, detriment, responsibility, deposit, or gift.
  3. Locate defects: screen past acts, illusory promises, preexisting duties, sham recitals, lack of authority, illegality, and failure of exchange.
  4. Use special transaction rules: separate earnest money, option fees, modifications, settlements, deeds, contingencies, and Frauds Act proof.
  5. Evaluate consequence: distinguish no consideration at formation from later breach or failure, then refer contested legal remedies.

How do the rules work in scenarios?

Reciprocal sale promises

Scenario: The buyer promises to pay $375,000 and close, while the seller promises to convey marketable title to the described property.

  1. The promises were exchanged for each other.
  2. Each party undertook a legal obligation.
  3. A separate earnest-money payment is not necessary to identify this exchange.

Answer: The reciprocal promises provide consideration.

Late earnest money

Scenario: A signed bilateral purchase contract requires a $5,000 deposit within two business days, but the buyer delivers it on day four.

  1. The buyer's and seller's sale promises can already supply consideration.
  2. The late deposit can be a breach, waiver, notice, cure, or remedy issue under the clause.
  3. The delay does not automatically prove that no contract formed.

Answer: Analyze the deposit clause separately from the existence of consideration.

Past landscaping

Scenario: After a neighbor landscaped an owner's yard without requesting payment, the owner promises to convey a vacant lot as thanks.

  1. The landscaping was completed before the promise.
  2. It was not requested as the price of the later conveyance promise.
  3. Gratitude or moral obligation does not turn the past act into a present bargain.

Answer: The old landscaping is past consideration and ordinarily does not support the new promise.

Illusory purchase promise

Scenario: A writing says the buyer will purchase only if the buyer later feels like buying, with no deadline, standard, or good-faith limit.

  1. The buyer retains unlimited choice whether to perform.
  2. No objective contingency or reasonable-efforts duty constrains that choice.
  3. The apparent promise supplies no real commitment.

Answer: The buyer's promise is illusory on the stated facts.

Option fee

Scenario: An owner promises to keep a $600,000 offer open for 30 days in exchange for the buyer's nonrefundable $2,500 option fee.

  1. The owner undertakes not to revoke during the stated period.
  2. The buyer provides the $2,500 in exchange for that commitment.
  3. Exercise and purchase-price payment remain separate steps.

Answer: The $2,500 supports the option promise if the agreement's other requirements are met.

Preexisting repair duty

Scenario: A signed contract already requires the seller to repair the roof. The buyer later promises an extra $4,000 solely for the seller to perform that same repair.

  1. The seller already owes the roof repair under the contract.
  2. Promising the identical performance adds no legal detriment.
  3. New consideration or another recognized modification basis would be needed.

Answer: The preexisting duty ordinarily does not support the buyer's new payment promise.

Unequal values

Scenario: A knowledgeable owner voluntarily agrees to sell vacant land for $90,000, and a later appraisal estimates $110,000. No unfairness or consent defect is stated.

  1. The parties exchanged real promises and the stated price.
  2. Consideration need not equal appraised value dollar for dollar.
  3. A later difference alone does not establish the exceptional gross-inadequacy case.

Answer: The value difference does not by itself make consideration legally insufficient.

What are the common exam traps?

Trap
Defining consideration as money only
Correction
A promise, act, forbearance, benefit, or legal detriment can supply the exchange.
Trap
Treating earnest money as the sole consideration
Correction
Reciprocal promises to sell and buy ordinarily support the purchase contract.
Trap
Voiding every late deposit automatically
Correction
Read the deposit, notice, cure, waiver, default, and remedy language.
Trap
Requiring equal market value
Correction
Legal sufficiency usually does not require equivalent economic values.
Trap
Saying adequacy never matters
Correction
Gross inadequacy combined with unfair or oppressive circumstances can support equitable relief.
Trap
Accepting a sham one-dollar recital automatically
Correction
A recital does not replace an actual bargained exchange when consideration is required.
Trap
Calling a gift promise a contract
Correction
Donative intent without an exchanged legal value ordinarily lacks consideration.
Trap
Treating past service as a current bargain
Correction
An act already completed independently of the promise is ordinarily past consideration.
Trap
Letting optional performance count as a promise
Correction
A wholly illusory promise creates no real commitment.
Trap
Calling every contingency illusory
Correction
Objective conditions, reasonable efforts, and good-faith standards can constrain real duties.
Trap
Paying extra for the identical existing duty
Correction
Doing only what is already owed ordinarily supplies no new consideration.
Trap
Confusing consideration with motive
Correction
The legal exchange differs from the personal reason for entering the deal.
Trap
Confusing no consideration with later breach
Correction
Formation without an exchange differs from failure to perform a promised exchange.
Trap
Using option fee as the purchase price
Correction
The option fee buys the decision period; the contract decides whether it credits toward price.
Trap
Letting the broker decide legal sufficiency
Correction
Document the promised exchange and refer a contested enforceability question to counsel.

Questions students ask about Consideration: Illinois Real Estate Exam Guide

What is consideration in a contract?

Consideration is the bargained-for exchange supporting contractual promises. Illinois decisions describe it as a promise, act, or forbearance sought in exchange for the other party's promise or performance. It can be a benefit to one side or a legal detriment or responsibility undertaken by the other. It is the exchange, not merely money.

What is consideration in a real estate sales contract?

The buyer promises to purchase and pay on the agreed terms, while the seller promises to convey the described real estate and perform the seller's obligations. Those reciprocal promises ordinarily provide consideration for a bilateral purchase contract. Earnest money may support the transaction, but it is not the only consideration and should not be confused with the entire exchange.

Is earnest money required for a valid Illinois real estate contract?

Not as a universal rule. Mutual promises can furnish consideration even if no earnest-money deposit is made at signing. The contract may nevertheless require a deposit by a stated deadline, making nonpayment a performance, notice, waiver, or remedy question. Do not conclude that every missing or late deposit prevented formation without reading the clause.

Must consideration have equal economic value?

Ordinarily, courts do not reprice a voluntary bargain merely because one side later thinks the exchange was unequal. The legal question is usually whether a bargained exchange exists, not whether values match dollar for dollar. Gross inadequacy combined with unfairness, oppression, incapacity, or unconscionable circumstances can support equitable relief, so the rule is not that amount never matters.

What is nominal consideration?

Nominal consideration is a small stated value, such as one dollar, used to evidence an exchange. A recital is not magic. The transaction must still involve a real bargained-for legal exchange where consideration is required. Deeds can use different rules from executory contracts, and a broker should not assume a printed recital resolves a contested formation issue.

What is an illusory promise?

An illusory promise appears to commit a party but leaves performance entirely optional, so the promisor has not actually undertaken a legal detriment. A promise to buy if I feel like it is the classic pattern. A valid contingency is different because it uses an objective event, a duty of good faith, reasonable efforts, or a defined satisfaction standard rather than unlimited discretion.

What is past consideration?

Past consideration is an act completed before and independently of the later promise. Because the act was not bargained for in exchange for that later promise, it ordinarily does not support it. If a buyer voluntarily repaired a seller's fence last year, the seller's new promise today to convey land is not supported merely by calling the old act consideration.

What is the preexisting-duty rule?

Doing only what a party is already legally obligated to do ordinarily supplies no new consideration for a new promise. A contract modification can still be supported by a new or different obligation, a reciprocal concession, an agreed resolution of a genuine dispute, or another recognized basis. The exact contract and governing law matter.

Why does an option contract need consideration?

An option separates two promises. The optionor promises to keep an offer open for the option period, and the optionee gives consideration for that binding commitment. Exercise then forms or activates the underlying transaction according to the option terms. Without consideration or another enforceability basis, a promise merely to leave an ordinary offer open may remain revocable.

Does consideration need to appear in the land-sale writing?

Section 3 of the Illinois Frauds Act states that consideration for an agreement within the Act need not be set forth or expressed in the writing and may be proved or disproved by other legal evidence. That narrow rule does not remove the need for consideration, make incomplete terms sufficient, or authorize a broker to rely on oral side promises.

Are these official PSI questions or legal advice?

No. The questions are original. Illinois decisions, statutes, court instructions, and the exam bulletin were checked through August 1, 2026. This is exam education, not legal advice. A live consideration dispute requires the complete agreement, modifications, payments, performance history, surrounding facts, and review by a qualified Illinois attorney.
