4.1 Contract Types and Required Elements
Key Takeaways
- A valid contract needs four essential elements: mutual assent (offer and acceptance), consideration, capacity, and lawful object
- Most purchase agreements are bilateral (promise for a promise); an open listing or option is unilateral (promise for an act)
- A counteroffer rejects and extinguishes the original offer; acceptance must mirror the offer exactly to form a contract
- Earnest money is a good-faith deposit, not the legal consideration; the promise to pay the price is the consideration
- Contracts with minors or mentally incompetent persons are voidable by the incapacitated party, not automatically void
Why Contracts Dominate the Exam
Every real estate transaction is built on contracts: listing agreements, buyer-representation agreements, purchase agreements, leases, and options. You must classify a contract and then confirm it has the elements required to be enforceable.
Core Contract Classifications
Express contract - terms are stated in words, written or oral.
Implied contract - formed by the conduct of the parties rather than stated words.
Bilateral contract - a promise exchanged for a promise; both parties are obligated.
Unilateral contract - a promise exchanged for an act; only one party is bound until the other performs.
Most purchase agreements are bilateral because the buyer promises to buy and the seller promises to sell. An open listing or an option is often unilateral because the owner is bound only if the other party performs the requested act.
Table: Contract Classifications
| Type | How It Forms | Real Estate Example |
|---|---|---|
| Express | Stated words (oral/written) | Signed purchase agreement |
| Implied | Conduct of the parties | Tenant pays rent, owner accepts, no lease |
| Bilateral | Promise for a promise | Buyer and seller both promise to perform |
| Unilateral | Promise for an act | Option: seller bound only if buyer exercises |
The Four Essential Elements
A contract is valid only if all four elements are present:
- Mutual assent - a meeting of the minds shown by a clear offer and matching acceptance.
- Consideration - something of legal value exchanged by each side.
- Capacity - the parties are legally competent to contract.
- Lawful object - the purpose is legal and not against public policy.
Some sources list five elements by separating offer and acceptance from mutual assent. Either framing is fine; just confirm all components are present.
Mutual Assent (Meeting of the Minds)
Mutual assent requires a definite offer and an acceptance that mirrors the offer exactly. This is the mirror image rule. If the offeree changes any material term, the response is a counteroffer, which rejects and terminates the original offer. The original offeror then becomes the new offeree.
An offer can also end by revocation before acceptance, lapse of a stated time, rejection, or death of a party before acceptance.
Consideration Versus Earnest Money
Consideration is the bargained-for exchange of value. In a sale, the buyer's consideration is the promise to pay the price, and the seller's is the promise to convey marketable title.
Earnest money is a good-faith deposit that shows the buyer is serious. It is commonly held in the broker's trust account, but it is NOT the legal consideration that forms the contract. A contract can be valid with zero earnest money if the mutual promises exist.
Worked Example
A buyer offers $400,000 with a $4,000 earnest money deposit. The seller signs without changes. The contract is valid because the mutual promises supply consideration. If the buyer had offered $0 earnest money but still promised to pay $400,000, the contract would still be valid.
Capacity and Lawful Object
Capacity means legal competence. Contracts with minors and persons judged mentally incompetent are voidable by the protected party, not automatically void. A corporation or estate must act through an authorized representative.
Lawful object means the purpose must be legal. A contract requiring a fair-housing violation or concealment of a known material defect is void.
Common Exam Traps
- Treating earnest money as the required consideration.
- Assuming a minor's contract is void; it is voidable by the minor.
- Forgetting a counteroffer kills the original offer.
- Confusing express (words) with implied (conduct) contracts.
Valid, Void, Voidable, Unenforceable
Even a contract with all four elements can fall into different enforceability categories. The exam tests these four labels relentlessly.
Table: Enforceability Status
| Status | Meaning | Real Estate Example |
|---|---|---|
| Valid | Binding and enforceable by either party | Signed, complete purchase agreement |
| Void | No legal effect from the start | Contract to sell land the seller does not own for an illegal use |
| Voidable | Valid until the protected party cancels | Contract signed by a 17-year-old |
| Unenforceable | Valid but a court will not enforce it | Oral agreement to sell a house |
The traps cluster here:
- A voidable contract is fully effective unless and until the protected party (minor, defrauded party, person under duress) chooses to disaffirm it.
- A void contract was never a contract at all; neither party can enforce it.
- An unenforceable contract is real but cannot be proven in court, usually because the Statute of Frauds required a writing that does not exist.
Exam Trap: Fraud, duress, undue influence, and misrepresentation make a contract voidable by the victim - not automatically void.
Offer and Acceptance: A Timing Scenario
Work through how an offer lives and dies.
Scenario. On Monday a buyer offers $350,000, good through Friday. On Tuesday the seller counters at $360,000. On Wednesday the buyer says nothing. On Thursday the seller calls back and says, 'Fine, I accept your original $350,000.'
- The seller's Tuesday counteroffer was a rejection of the $350,000 offer - it terminated it.
- Once terminated, the $350,000 offer no longer exists, so the seller cannot revive it on Thursday by 'accepting' it. The buyer would have to make a new offer.
- If instead the buyer had simply accepted the $360,000 counter on Wednesday, a valid contract would form at that moment (mirror-image acceptance).
Exam Trap: A counteroffer destroys the original offer; the original offeror cannot later snap it back up. Acceptance must mirror the most recent open offer to form the contract.
A seller receives a $375,000 offer, crosses out the closing date, writes in a date two weeks later, and signs. What has the seller created?
