Study guide
Contracts are the mechanism through which every real estate transaction actually happens, and agency law defines whose interests a broker and its licensees are legally bound to protect. This chapter reviews the requirements for a valid, enforceable contract, the practical documents built from that foundation, and the duties owed under different representation structures. Broker-level mastery means being able to explain to a new agent not just what a document says, but why a technical defect (a missing signature, an expired option, an undisclosed dual agency) can unravel an entire deal.
Elements and Validity of a Contract
A legally enforceable contract requires five elements: competent parties (of legal age and sound mind), mutual consent (a genuine meeting of the minds, free of fraud, duress, or undue influence), legal purpose, consideration (something of value exchanged, which can be money, a promise, or performance), and, for real estate specifically, a written document satisfying the Statute of Frauds. The Statute of Frauds requires that contracts for the sale of real property, and most leases exceeding one year, be in writing and signed by the party to be bound in order to be enforceable in court; an oral agreement to sell land is generally unenforceable even if both parties agree it was made. A contract's validity falls into one of several categories. A valid contract contains all required elements and is fully enforceable. A void contract lacks one or more essential elements and was never enforceable at all, such as a contract for an illegal purpose. A voidable contract appears valid on its surface but contains a defect, such as one party's minority or a misrepresentation, giving the injured party the option to void it or affirm it. An unenforceable contract may have been validly formed but cannot be enforced in court because of a technical defect, such as failing to satisfy the Statute of Frauds, or because the time to sue under it has expired. Offer and acceptance form the mechanical core of contract formation: an offer is a definite proposal communicated to another party, an acceptance must be a mirror-image, unconditional agreement to those exact terms, and any change to the terms in a response constitutes a counteroffer, which legally terminates the original offer and becomes a new offer in its own right, awaiting acceptance from the original offering party.
Bilateral, Unilateral, and Option Contracts; E-Signatures and Remedies
A bilateral contract involves an exchange of mutual promises; both parties are obligated the moment the contract is formed, as in a standard purchase agreement where the buyer promises to pay and the seller promises to convey. A unilateral contract involves a promise in exchange for an act, and only one party is bound until the other performs; an open listing is a common unilateral arrangement, since the seller promises a commission only to whichever broker actually produces a ready, willing, and able buyer, and no broker is obligated to produce one. An option contract gives one party (the optionee) the exclusive right, but not the obligation, to purchase or lease property within a stated period at agreed terms, in exchange for option consideration paid to the optionor; the optionor is bound for the option period, while the optionee can simply let the option lapse. The federal E-SIGN Act and the state-level Uniform Electronic Transactions Act (UETA) give electronic signatures the same legal force as handwritten signatures for most real estate contracts, provided all parties have consented to conduct the transaction electronically. When one party fails to perform a contractual duty without legal excuse, that is a breach, and the non-breaching party may pursue several remedies: rescission, which cancels the contract and attempts to restore both parties to their pre-contract position; compensatory damages, a money award to cover actual losses; specific performance, a court order compelling the breaching party to complete the transaction as agreed, more commonly available in real estate because each parcel of land is considered legally unique; or, if the contract includes a liquidated damages clause, retention of the earnest money deposit as a pre-agreed measure of damages, typically the buyer's sole remedy under that clause. Cancellation and termination differ from rescission: cancellation typically ends a contract going forward without unwinding what has already occurred, while termination ends the agreement per its own terms, such as at the natural expiration of a listing period.
Purchase Agreements, Contingencies, Leases, and Multiple Offers
A purchase agreement (sales contract) is the central document of a transaction, identifying the parties, the property, the price, the financing terms, the closing date, and any contingencies. A contingency is a condition that must be satisfied for the contract to become fully binding; common contingencies include financing (the buyer's obligation depends on securing a loan on stated terms), inspection (the buyer may cancel or renegotiate based on inspection findings within a stated period), appraisal (the property must appraise at or above the purchase price), and sale of the buyer's current home. An addendum adds new terms to a contract at or before signing and is incorporated as part of the original agreement, while an amendment modifies the terms of a contract that has already been fully executed by all parties; both require signatures from every party bound by the original contract to be effective. A lease is a contract that conveys the right of possession and use of property for a stated term in exchange for rent, without conveying title, and may be a bilateral contract obligating both landlord and tenant. A lease-purchase (or lease-option) agreement combines a standard lease with either an obligation (lease-purchase) or an option (lease-option) for the tenant to buy the property later, often with a portion of rent credited toward the eventual purchase price; brokers must ensure these agreements clearly state whether the tenant is obligated to buy or merely holds the right to buy, since that distinction changes the legal remedies available if the tenant declines. In a multiple-offer situation, a seller may accept one offer outright, reject all, or counter one or more offers; a seller cannot bind more than one buyer simultaneously unless offers are presented as clearly contingent backup positions, and brokers must handle multiple offers according to the seller's instructions while treating all prospective buyers honestly and without misrepresentation about competing offers.
Agency Creation, Types, and Fiduciary Duties
Agency is a legal relationship in which one party, the agent, is authorized to act on behalf of another, the principal (or client), in dealings with third parties. Agency is typically created through an express written agreement, such as a listing agreement or a buyer representation agreement, though it can also arise by implication through the parties' conduct, or, rarely, by ratification, when a principal later accepts an unauthorized act. A listing agreement establishes seller representation and commonly takes one of three forms: an exclusive-right-to-sell listing, entitling the broker to a commission regardless of who finds the buyer, including the seller; an exclusive-agency listing, entitling the broker to a commission unless the seller finds the buyer without any broker's help; or an open listing, allowing the seller to hire multiple brokers simultaneously and pay only whichever one successfully produces a buyer. A buyer or tenant representation agreement establishes an equivalent agency duty running to the buyer or tenant. Where a jurisdiction and brokerage structure permit it, a licensee may instead act as a transaction broker (sometimes called a facilitator or non-agent), assisting both parties in completing the transaction fairly without representing either party's interests in a fiduciary capacity; this arrangement carries a reduced duty set and must be clearly disclosed, since the duties owed to a client and the duties owed to a customer are meaningfully different. An agent representing a client owes fiduciary duties, commonly remembered by the acronym OLDCAR: Obedience to lawful instructions, Loyalty (placing the client's interests above the agent's own and above any other party's), Disclosure of material facts affecting the client's interests, Confidentiality of the client's personal and negotiating information (surviving after the relationship ends), Accounting for all funds and property handled on the client's behalf, and Reasonable care and skill. A licensee dealing with a customer (a non-represented party or the other side's client) owes a lesser, non-fiduciary set of duties: honesty, fair dealing, and disclosure of known material defects, but not loyalty, obedience, or confidentiality regarding the customer's own negotiating position.
Dual Agency, Disclosure, Powers of Attorney, and Termination of Agency
Dual agency arises when one broker, or in some structures one licensee, represents both the buyer and seller in the same transaction; because full loyalty to two opposing parties is not logically possible, dual agency is heavily restricted, requires informed written consent from both parties after full disclosure, and is prohibited outright in some jurisdictions. Designated agency, permitted in many states as an alternative, allows a broker to appoint two different licensees within the same firm to represent the buyer and the seller separately, with each designated agent owing full fiduciary duties to their own client while the broker itself remains a form of limited dual agent supervising both sides. Any agency relationship, along with any conflict of interest such as the broker's own financial interest in a property or a family relationship with a party, must be disclosed to all parties at the earliest practical opportunity, typically in writing, before any confidential information is shared. A power of attorney is a separate legal instrument, distinct from real estate agency, in which one person (the principal) authorizes another (the attorney-in-fact) to act on their behalf in legal or financial matters; a general power of attorney grants broad authority, while a special (limited) power of attorney authorizes only specific acts, such as signing closing documents for a principal who cannot attend in person, and must be properly executed, often notarized and recorded, to be accepted by a title company. Agency relationships terminate through several routes: completion of the purpose (the transaction closes), expiration of the stated term, mutual agreement to cancel, revocation by the principal or renunciation by the agent (though this may create liability for breach), destruction of the property, death or incapacity of either party, or operation of law such as bankruptcy. Brokers must ensure listing files clearly document the termination date and any post-termination protection period, a clause entitling the broker to a commission if the property sells within a set window after expiration to a buyer the broker introduced during the listing term.

Exam tips
- If an answer changes any term of an offer, it is a counteroffer, not an acceptance, and it kills the original offer even if the change seems minor.
- Distinguish void (never valid, no element present) from voidable (valid on its face, one party can elect to cancel) from unenforceable (validly formed but blocked in court, often a Statute of Frauds problem).
- Use OLDCAR (Obedience, Loyalty, Disclosure, Confidentiality, Accounting, Reasonable care) to instantly separate fiduciary duties owed to a client from the thinner honesty-and-fair-dealing duties owed to a customer.
- Dual agency and designated agency are not the same thing — dual agency has one agent for both sides with informed consent required; designated agency assigns two different agents within one firm.
- A power of attorney is not a real estate agency relationship — do not confuse an attorney-in-fact's authority to sign documents with a broker's fiduciary duties to a client.
