A brokerage contract with exclusivity ties the property owner to a single broker or real estate agency. The professional keeps the right to a commission even if the owner, or a third party, completes the sale while the contract is in force.

The brokerage contract and its essential elements

The real estate brokerage contract is governed by Articles 722 to 729 of the Civil Code and by Law 6.530/1978, which regulates the profession of real estate broker. It is a results-based contract: the broker agrees to bring the parties together and make the deal possible, and the broker is paid only if the intermediation succeeds. The essential elements of the contract are the identification of the parties, a description of the property, the commission percentage, the term, and, where applicable, the exclusivity clause.

A brokerage contract can be oral, but putting it in writing is strongly recommended, because it makes it easier to prove the agreed terms if a dispute goes to court. The document should be clear about each party’s obligations, especially the amount of the commission, the payment terms, and whether or not the arrangement is exclusive.

Hiring a broker registered with CRECI (Regional Council of Real Estate Brokers) is a legal requirement for practicing the profession lawfully. Intermediation by an unlicensed person is the unlawful practice of the profession, which can lead to administrative sanctions and undermine the validity of the brokerage contract.

The exclusivity clause: scope and limits

An exclusivity clause is a contract provision in which the property owner agrees not to hire any other broker or agency while the contract is in force, leaving the intermediation exclusively to the chosen professional. Article 726 of the Civil Code expressly provides for this clause and states that, where there is exclusivity, the broker is owed the commission even if the owner completes the deal directly.

Exclusivity benefits both sides. For the broker, it provides assurance that the investment in marketing, in handling interested buyers, and in the intermediation work will be paid for. For the owner, it secures the broker’s full commitment to the sale, since the broker knows there is no risk of losing the commission to a competitor.

The document should be clear about each party’s obligations, especially the amount of the commission, the payment terms, and whether or not the arrangement is exclusive.

That said, exclusivity must have a definite and reasonable term. Courts consider excessively long terms without justification to be abusive. Terms of 90 to 180 days are the most common in the market, and they can be renewed by agreement between the parties. The clause should also set out the conditions for early termination, so the owner does not stay bound indefinitely to a broker with whom he or she is unhappy.

The right to a commission: when it arises and when it ends

The broker’s right to a commission arises when the brokered deal is concluded, under Article 725 of the Civil Code. The deal is concluded when buyer and seller sign the purchase and sale agreement or the final deed. Simply showing the property to a prospective buyer, without a completed sale, does not create a right to a commission.

A recurring question involves the so-called “efficient cause.” Suppose the broker introduces the buyer to the seller but is dismissed before the deal closes, and the sale is later completed with the same buyer. Is the commission still owed? Article 727 of the Civil Code answers yes: if the deal is concluded as a result of the broker’s efforts, the commission is owed, even if the broker was left out of the final negotiations.

Courts have applied this principle widely. They recognize the right to a commission even when the buyer contacts the seller directly after a visit arranged by the broker. Proof that the broker brought the parties together and made the deal possible is enough to support the right to payment.

When the owner breaches exclusivity

If the owner breaches the exclusivity clause by selling the property directly or through another broker while the contract is in force, the owner must pay the commission to the exclusive broker, as Article 726 of the Civil Code expressly provides. This obligation exists whether or not the broker was the one who introduced the buyer who actually purchased the property.

In addition to the commission, the broker may seek compensation for moral and material damages caused by the breach, including expenses for advertising, travel, and time devoted to the intermediation. Courts recognize the right to compensation where exclusivity is breached without justification.

For the owner, the safest way to end exclusivity without violating the contract is to wait for the agreed term to expire or to negotiate an amicable termination with the broker, documenting the termination agreement in writing. Mere dissatisfaction with the broker’s work does not justify unilaterally disregarding the clause.

Shared brokerage and agency networks

Shared brokerage occurs when more than one broker or agency takes part in the intermediation and they split the commission. The practice is common when the seller’s broker (who holds the exclusive listing) agrees to let brokers from other agencies present buyers, which increases the property’s exposure in the market.

In shared brokerage, the professionals agree on the commission split in advance. It is usually equal shares (50% for the listing broker and 50% for the selling broker), or different percentages depending on the negotiation. The owner still pays the full commission (usually 6%), and the brokers divide it among themselves.

Agency networks and online property-sales platforms significantly expand the reach of the marketing, which benefits the owner. Joining a sharing network is a strategic decision for the exclusive broker, who must weigh whether the greater exposure is worth splitting the commission. The owner cannot require the broker to share, but can include that term as a condition for granting exclusivity.

Frequently Asked Questions

Can the broker charge a commission if the sale falls through because of the buyer?

As a rule, if the deal is not completed, the broker is not entitled to a commission, whatever the reason. However, if the purchase and sale agreement was signed and the buyer later backs out (with no withdrawal clause), many courts hold that the useful result has already been achieved and the commission is owed. It depends on the facts of each case. If the broker fully performed the obligation (brought the parties together and made it possible to sign the contract), the right to the commission is perfected at the moment the deal is concluded and is not affected by later events.

What is the difference between a sales authorization and an exclusivity contract?

A sales authorization is a general document in which the owner allows a broker to advertise the property and offer it to potential buyers, without exclusivity. The owner can hire several brokers at the same time, and the commission is owed only to the professional who actually concludes the deal. An exclusivity contract, by contrast, ties the owner to a single broker and ensures the commission is paid to the chosen professional even if a third party completes the sale. Exclusivity gives the broker greater security, and the broker tends to invest more resources in marketing the property.

How are commission disputes between brokers resolved?

Disputes between brokers over the right to a commission should be resolved based on the contract documents and on proof of who actually brokered the deal. When there is an exclusivity contract, the exclusive broker takes priority. When there is no exclusivity, the efficient cause theory prevails: the broker who shows that he or she brought the parties together and made the deal possible is entitled to the commission. CRECI has mediation mechanisms for resolving conflicts between brokers, and going to court is available when mediation is not enough.
