4.1 Contract Types and Required Elements

Why Contract Law Anchors the Exam

Real estate is the buying and selling of promises about land. Before a deed ever changes hands, the parties have committed in a contract. Roughly one in eight national questions touches contract concepts, so a candidate who can classify an agreement and spot a missing element has a structural advantage.

The two skills tested most often are (1) naming the type of contract from a fact pattern and (2) deciding whether a valid contract even exists.

The Four Classifications

Contracts are sorted two ways at once: by how the promise is expressed and by how many promises are made.

• Express agreements state their terms outright, spoken or written.
• Implied agreements arise from conduct, where behavior signals agreement no one announced.
• Unilateral agreements trade a promise for a completed act; only one party is bound until the act occurs.
• Bilateral agreements swap a promise for a promise, binding both sides at signing.

A signed offer to purchase is express and bilateral. An open-listing reward paid only if a broker actually produces a buyer behaves like a unilateral contract.

The Required Elements

A legally valid contract needs each of these. Drop one and the agreement weakens to void, voidable, or unenforceable.

1. Competent parties with legal capacity to contract.
2. Mutual assent (a meeting of the minds) shown by offer and acceptance.
3. Consideration, a bargained-for exchange of value.
4. Lawful object, a purpose that does not break the law or public policy.

Many texts also list "offer and acceptance" as a fifth element, but that is simply how mutual assent is proven, so treat it as part of assent rather than something extra.

Mutual Assent and the Offer-Acceptance Engine

Mutual assent means both sides agree on the same essential terms: the parties, the property, the price, and the basic conditions. If the buyer believes the price is $420,000 while the seller signs thinking $442,000, the minds never met and no contract formed.

Acceptance must be the mirror image of the offer. Change a single material term and you have not accepted; you have made a counteroffer, which legally rejects and extinguishes the prior offer. Suppose a buyer offers $500,000 with a 45-day close. The seller writes back $512,000 with a 30-day close and signs. That seller response is a counteroffer. If the buyer then says "forget it, I accept the original $500,000," there is nothing to accept; the buyer's first offer died the moment the counter went out.

Consideration Is Not Earnest Money

Consideration is the value each side bargains to give. In a sale, the buyer's consideration is the promise to pay the price; the seller's is the promise to convey title. A bare promise to make a gift fails for lack of consideration.

Earnest money is a separate, optional deposit that signals good faith and is later credited toward the price. A contract with a $1 deposit, or even none, can still be perfectly valid because the mutual promises supply the consideration.

Capacity and Lawful Object

Capacity asks whether a party may legally bind itself. Minors, persons judged mentally incompetent, and the heavily intoxicated may sign, but the resulting contract is voidable at the choice of the protected party, who can affirm it or walk away. The competent party cannot escape; only the protected side gets the exit.

Entities act through authorized representatives. A corporation signs through an officer with authority; an estate through its executor. A signature from someone without authority can leave the contract unenforceable against the entity.

Lawful object means the deal cannot require an illegal or against-public-policy act. A contract to conceal a known structural hazard, or to refuse buyers based on a protected class under fair housing law, is void from the start.

Common Traps

• Treating earnest money as the element of consideration.
• Assuming a counteroffer leaves the original offer alive.
• Calling a minor's contract "void" when it is voidable.
• Believing every contract must be written; that is the statute of frauds (Section 4.2), not a universal rule.

Classifying Contracts and the Statute of Frauds

The exam tests several overlapping classifications. A bilateral contract exchanges a promise for a promise (a signed purchase agreement: buyer promises to pay, seller promises to convey), while a unilateral contract exchanges a promise for an act (an open listing or an option, where only one party is bound until the other performs). An executory contract is still being performed; an executed contract is fully completed. An express contract is stated in words; an implied contract arises from conduct.

The statute of frauds requires that contracts for the sale of real estate, and leases longer than one year, be in writing and signed by the party to be charged to be enforceable. The five essential elements of any valid contract are: (1) competent parties, (2) mutual assent (offer and acceptance, a true meeting of the minds), (3) lawful object, (4) consideration, and (5) for real estate, a written form satisfying the statute of frauds.
