2.3 Brokerage Agreements

Key Takeaways

  • As of January 1, 2025, Illinois requires a written brokerage agreement with every buyer and seller, exclusive or non-exclusive
  • Exclusive right to sell pays the broker regardless of who finds the buyer; exclusive agency lets the owner sell commission-free
  • Every listing must state a definite termination date and cannot auto-renew without clear written terms
  • Brokerage agreements must now disclose what the broker charges its client and what it may pay a cooperating broker
  • Net listings are strongly discouraged in Illinois because the built-in conflict collides with the licensee's fiduciary and disclosure duties

The 2025 Written-Agreement Mandate

The biggest change to memorize: effective January 1, 2025, a sponsoring broker must put every brokerage relationship in a written brokerage agreement — for sellers and buyers, whether the relationship is exclusive or non-exclusive. The Act now defines a non-exclusive brokerage agreement as one giving the broker, through its sponsored licensees, the non-exclusive right to act for the client. The agreement should be provided when services begin and signed no later than when the consumer tours a property.

Exclusive agencySeller, unless the owner procures the buyerYesLess common
Open listingOnly the broker who is the procuring causeYesRare; high risk to brokers

Exclusive right to sell vs. exclusive agency

This pairing is heavily tested. Under an exclusive right to sell, the seller owes the commission even if the seller personally finds the buyer — the broker is protected from being cut out. Under an exclusive agency, the broker earns only if the broker (or any cooperating broker) produces the buyer; if the owner finds the buyer unaided, no commission is due. The difference is a single carve-out: who gets the credit when the owner sells it themselves.

Net listings — discouraged in Illinois

A net listing sets a price the seller must "net," letting the broker keep everything above it as commission. Illinois does not bless this arrangement: it pits the licensee's profit directly against the loyalty and disclosure duties owed to the seller, because the broker is incentivized to suppress the sale price or hide higher offers. Treat net listings as strongly discouraged, permitted only with full written disclosure of the conflict — and assume the exam wants you to flag the fiduciary danger, not endorse it.

Required Elements of a Valid Agreement

ElementRequirement
In writingMandatory for all clients as of 2025
PartiesNames of client(s) and the sponsoring broker
Property / scopeAddress or legal description (listings); search scope (buyers)
Agency relationshipDesignated agency unless otherwise agreed in writing
CompensationAmount charged to the client and amount payable to a cooperating broker
TermDefinite start and end dates
SignaturesAll required parties, before touring

The definite-termination-date rule

Illinois will not enforce an open-ended listing. Every agreement needs a fixed end date; an automatic-renewal or "holdover" clause must be clearly and conspicuously stated. A listing with no termination date is a License Act violation — a frequent distractor on the exam.

Buyer Representation Agreements

Buyer agreements follow the same 2025 written-agreement rule.

ProvisionWhy it matters
Exclusive vs. non-exclusiveExclusive: one broker; non-exclusive: buyer may use others
CompensationHow and by whom the buyer's broker is paid — critical post-2024 commission changes
Term and terminationDefinite duration and exit terms
Designated agent namedThe specific licensee representing the buyer

Termination of Agreements

MethodNotes
ExpirationThe definite end date arrives
Mutual consentBoth parties agree to cancel
PerformanceThe transaction closes
BreachOne party violates material terms
Death or incapacityOf the principal or the individual licensee
Destruction of propertySubject matter no longer exists

Worked scenario: A seller signs an exclusive agency listing, then finds the buyer entirely on their own through a coworker — no broker involved. The seller owes no commission, because exclusive agency reserves the owner's right to sell unaided. Had it been an exclusive right to sell, the full commission would be due.

Holdover / Protection Clauses and Procuring Cause

Many Illinois listings contain a protection (holdover) clause: if the property sells within a stated number of days after the listing ends to a buyer the broker introduced during the term, the seller still owes the commission. This prevents a seller from waiting out the listing to dodge the fee. The clause must be in writing and is enforceable only against named or registered prospects — not against any random later buyer.

When two brokers each claim a commission, the deciding concept is procuring cause — which broker's efforts set in motion the unbroken chain of events that led to the sale. An open listing rewards only the procuring-cause broker, which is exactly why open listings are risky: a broker can invest effort yet earn nothing.

Why Written Agreements Protect the Licensee

The 2025 mandate is not just consumer protection — it shields the broker. Without a written brokerage agreement, a buyer's broker may struggle to enforce a compensation claim, and a listing broker may be unable to collect under the Statute of Frauds, which generally requires real-estate commission agreements affecting an interest in land to be evidenced in writing. The written agreement is the licensee's proof of both the relationship and the fee.
