4.1 Contract Types and Required Elements
Key Takeaways
- A valid contract requires offer, acceptance, consideration, legal capacity, and lawful object; missing any one makes it void or voidable.
- Real estate contracts must be in writing to be enforceable under the Statute of Frauds.
- Contracts are classified by formation (express/implied), obligation (bilateral/unilateral), and enforceability (valid/void/voidable/unenforceable).
- An option is a unilateral contract: the seller is bound, the optionee is not, until the option is exercised.
4.1 Contract Types and Required Elements
A contract is a legally enforceable agreement between competent parties to do or refrain from doing a lawful act. The national exam tests the building blocks before it tests forms, so master the five essential elements first. If any element is absent, the agreement may be void from the start or merely voidable by one party.
The Five Essential Elements
- Offer and acceptance (mutual assent) — a meeting of the minds. The offer must be definite and communicated; acceptance must mirror the offer.
- Consideration — something of legal value exchanged. Money is common, but a promise can be consideration.
- Legal capacity — parties must be of legal age and sound mind. Contracts with minors are generally voidable by the minor.
- Legality of object — the purpose must be lawful. A contract to do something illegal is void.
- Reality of consent — assent free of fraud, misrepresentation, duress, menace, or undue influence.
Mutual Assent: Offer and Counteroffer
A counteroffer rejects the original offer and creates a new one. Once rejected, the original offer cannot be accepted unless re-extended. Trap: a buyer cannot "change their mind" and accept yesterday's offer after countering it.
Acceptance is effective only when communicated to the offeror (or the offeror's agent). Silence is not acceptance. An offer terminates by lapse of time, revocation before acceptance, rejection, counteroffer, death or incapacity of a party, or destruction of the subject property.
Worked example. A buyer offers $400,000. The seller responds at $415,000 (a counteroffer). The buyer then offers $408,000 (another counteroffer). The seller now says "I accept your original $400,000." There is no contract — the original $400,000 offer died when the seller countered at $415,000. The seller's purported acceptance is itself a new offer the buyer may accept or reject.
Classifying Contracts
Exam questions love classification. Use this table.
| Basis | Type | Meaning |
|---|---|---|
| Formation | Express | Terms stated in words (oral or written) |
| Formation | Implied | Terms inferred from conduct |
| Obligation | Bilateral | Both parties promise to perform (most sales contracts) |
| Obligation | Unilateral | One party promises; other acts to accept (option, open listing) |
| Enforceability | Valid | Has all elements; fully enforceable |
| Enforceability | Void | No legal effect ever (illegal object) |
| Enforceability | Voidable | Valid until disaffirmed (minor, fraud) |
| Enforceability | Unenforceable | Valid but no legal remedy (oral land sale, expired) |
Option contract. A buyer pays the seller for the exclusive right to buy within a set period at a set price. It is unilateral: the seller is bound to keep the offer open; the optionee (buyer) is not obligated to buy. Option consideration is usually non-refundable but may apply to the purchase price if the option is exercised.
The Statute of Frauds
The Statute of Frauds requires certain contracts to be in writing to be enforceable. For real estate this includes: contracts for the sale of real property, leases longer than one year, and (in most states) listing agreements that pay a commission. An oral land-sale contract is not void — it is unenforceable; a court will not order specific performance on it.
Trap: Memorize that the writing requirement makes an oral land contract unenforceable, not void. The distinction is a frequent answer-choice swap.
Void, Voidable, and Unenforceable Compared
Exam writers separate four near-synonyms, and choosing the wrong one is a common miss. Anchor each to a concrete fact pattern:
- Void — no contract ever existed; it cannot be enforced by anyone. A contract to commit an illegal act, or a deed signed by someone already declared mentally incompetent, is void from the start.
- Voidable — a real contract that one party may disaffirm (cancel) or ratify. A contract signed by a minor, or one induced by fraud or duress, is voidable by the protected party but binding on the other.
- Unenforceable — a valid contract a court will not enforce because of a technical bar, such as an oral land sale (Statute of Frauds) or a claim past the statute of limitations.
- Valid — has all elements and binds both parties.
Worked scenario: a 17-year-old signs a purchase contract. It is voidable by the minor, who may walk away, but the adult seller remains bound until the minor disaffirms. Compare a contract to buy property for an illegal gambling operation — that is void, and neither side can enforce it.
Reality of Consent in Practice
The fifth element, genuine assent, is tested through the defenses that destroy it:
- Fraud — an intentional misstatement of a material fact relied on by the other party (makes the contract voidable, and may support damages).
- Innocent misrepresentation — an unintentional false statement; supports rescission but not fraud damages.
- Duress / menace — consent forced by an unlawful threat.
- Undue influence — unfair pressure by someone in a position of trust (e.g., a caretaker over an elderly owner).
- Mutual mistake — both parties err about a material fact, such as the identity of the parcel; the contract can be rescinded.
A unilateral mistake (only one party is wrong) usually does NOT void the deal unless the other party knew of and exploited the error. Distinguishing fraud (intentional) from innocent misrepresentation (unintentional) controls whether damages, rescission, or both are available — a frequent answer-choice pairing.
A seller receives a $300,000 offer and responds with $320,000. The buyer then sends $310,000. The seller now signs and returns the original $300,000 offer. What is the legal status?
An oral agreement to sell a parcel of land is best described as:
