4.1 Contract Types and Required Elements
Key Takeaways
- A valid contract needs competent parties, mutual assent, consideration, and a legal purpose; real estate sales also require a signed writing (Statute of Frauds).
- Void means no legal effect ever; voidable means valid until disaffirmed; unenforceable means valid in form but not provable in court.
- A counteroffer terminates the original offer - the original can no longer be accepted.
- An option is the textbook unilateral contract; a typical purchase agreement is bilateral.
- Courts do not weigh the adequacy of consideration, but it must be legally sufficient.
Contract Types and Required Elements
A contract is a legally enforceable promise (or set of promises) between two or more parties. Real estate practice is built on contracts: listing agreements, purchase agreements, options, leases, and buyer-broker agreements. The exam expects you to know the elements that make any contract valid and the vocabulary used to classify contracts.
The Essential Elements
Every valid contract must contain the following elements. A missing element changes the contract's legal status (void, voidable, or unenforceable).
Five Elements of a Valid Contract
| Element | What it means | Common trap |
|---|---|---|
| Competent parties | Legal age and sound mind | A minor's contract is voidable by the minor, not void |
| Mutual assent | Offer + acceptance ("meeting of the minds") | A counteroffer terminates the original offer |
| Consideration | Something of legal value exchanged | Love and affection is NOT valid consideration in a sale |
| Legal purpose / legality of object | Object must be lawful | A contract to sell something illegal is void |
| Offer and acceptance in writing | Real estate transfers fall under the Statute of Frauds | Oral land-sale contracts are unenforceable |
Note the difference between consideration generally and the Statute of Frauds requirement of a writing. Consideration need not be money equal to value; courts do not weigh adequacy. But for a sale of real property, a signed writing is required to enforce it.
Classifying Contracts
The exam loves classification pairs. Memorize these:
- Express vs. implied - express is stated in words (written or oral); implied is created by conduct.
- Bilateral vs. unilateral - bilateral exchanges a promise for a promise (a typical sales contract). Unilateral is a promise in exchange for an act; only one party is obligated until the act is performed (an option is the classic example).
- Executed vs. executory - executed means fully performed by all parties; executory means something remains to be done. A signed purchase contract before closing is executory; after closing it becomes executed.
Legal Status of Contracts
- Valid - meets all elements; fully enforceable.
- Void - no legal effect from the start (e.g., illegal object, a forged deed).
- Voidable - valid until a party with the right elects to disaffirm (e.g., a minor's contract, a contract induced by fraud or duress).
- Unenforceable - valid in form but cannot be enforced in court (e.g., an oral land-sale contract barred by the Statute of Frauds, or one past the statute of limitations).
A 17-year-old signs a purchase agreement to buy a condominium. What is the legal status of this contract?
Worked Example: Counteroffer Mechanics
Buyer offers $300,000. Seller responds with $315,000. Before the buyer answers, the seller changes their mind and tries to accept the original $300,000 offer.
- The seller's $315,000 response was a counteroffer, which legally rejects and terminates the buyer's $300,000 offer.
- The seller therefore has nothing left to "accept." There is no contract at $300,000.
- A new meeting of the minds requires the buyer to accept the $315,000, or the parties to negotiate anew.
This is a frequent exam trap: a counteroffer is simultaneously a rejection of the prior offer. Only the offeror can revoke an offer (any time before acceptance), and only the offeree can accept it - and only while it is open.
Which contract is BEST described as unilateral?
The Statute of Frauds in Detail
The Statute of Frauds requires certain contracts to be in writing and signed by the party to be charged. In real estate, this includes contracts for the sale of land, leases longer than one year (in most states), and listing agreements (in most states). The purpose is to prevent fraudulent claims based on oral promises about valuable interests in land.
Key exam points:
- An oral land-sale contract is unenforceable, not void. If both parties voluntarily perform, the transfer stands.
- The part-performance doctrine can make an oral contract enforceable when a buyer takes possession, pays, and improves the land in reliance on it.
- The writing need not be a single formal document; a memorandum identifying the parties, the property, the price, and signatures can satisfy the statute.
Offer, Acceptance, and Termination of Offers
Mutual assent forms when a valid offer is met by an unqualified acceptance communicated to the offeror. The exam tests how an offer can end before acceptance:
- Revocation by the offeror before acceptance.
- Rejection or counteroffer by the offeree.
- Lapse of time stated in the offer, or a reasonable time if none is stated.
- Death or incapacity of either party before acceptance.
- Destruction of the subject property before acceptance.
Acceptance of a real estate offer must generally be in writing and communicated. The 'mailbox rule' (acceptance effective on dispatch) is commonly modified by contract to require actual delivery, so always read the contract's communication terms.
Void, Voidable, and Unenforceable: Drawing the Lines
The exam constantly tests these three statuses, which are easy to blur:
- Void - no contract ever existed (illegal purpose, or a party lacked legal capacity such as an adjudicated incompetent). It cannot be ratified.
- Voidable - a valid contract that one party may cancel or affirm (a minor's contract, or one induced by fraud, duress, or misrepresentation). It is enforceable until the protected party rescinds.
- Unenforceable - valid in substance but the courts will not enforce it, typically because it violates the Statute of Frauds (not in writing) or the statute of limitations has run.
A real estate purchase contract that is fully oral is unenforceable, not void: if both parties perform voluntarily it stands, but neither can sue to compel performance. A contract signed under fraud is voidable by the defrauded party. Match the defect to the status and the question usually answers itself.
