How to terminate a brokerage agreement with a real estate agency

Grounds, penalty clauses and legal steps to end an exclusivity agreement with a real estate agency in Mexico without overpaying.

Signing the exclusivity letter or brokerage agreement with a real estate agency is one of the most underestimated legal commitments when selling a property in Mexico. These agreements usually carry term, commission and penalty clauses unfavorable to the seller, and ending them early can be expensive if not done right. This article explains how to legally terminate a sale assignment and what to do when the agency refuses to release the property.

The legal framework

The real estate brokerage agreement in Mexico is governed by the Commercial Code and the state civil codes, depending on who is contracting (a natural person dealing with their personal estate: civil; a merchant: commercial). There is no specific federal law regulating real estate brokers; some states have laws (for example, Quintana Roo, Jalisco, Nuevo León, CDMX) that require registration as a real estate broker or real estate advisor.

The key point: it is a service provision contract, not a sales contract. The seller remains the owner and, as a general rule, can revoke the assignment at any time, subject to whatever the contract sets as exclusivity and penalty.

Types of assignment

Simple (non-exclusive) assignment

It allows the owner to hire several agencies and to sell on their own. Commission is only paid to the agency that actually closes the deal. To end the assignment a letter is enough. It is the most flexible form.

Exclusive assignment

Only one agency can offer the property during the term. If the owner sells on their own or with another agency, they must pay the full commission under the penalty clause. This is the most contentious mode.

"Open with co-broking" assignment

A middle option: one agency leads but shares with others in the market. It usually has functional exclusivity with a single point of contact.

When you can terminate without penalty

There are at least five grounds protecting the seller:

  1. Term expiration: most agreements have a term (3, 6, 12 months) that must be honored. After that date the contract ends, except for tacit renewal clauses.
  2. Serious breach by the agency: not listing the property, not handling visits, not reporting, not responding.
  3. Defects of consent: if you signed under pressure, without understanding the penalty clause, without receiving a copy of the contract.
  4. Abusive clauses: Article 85 of the LFPC (Federal Consumer Protection Law) considers as abusive clauses that auto-renew without notice, that impose disproportionate commissions or that forbid termination.
  5. Force majeure: serious illness, divorce, withdrawal of the property from the market for family reasons.

When commission must be paid

Even when terminating, the agency is entitled to commission when:

  • It introduced the buyer that ultimately closed, and the deal is signed within the protection period (typically 90 to 180 days after termination).
  • It directly negotiated with a client to whom it brought visits and, after termination, that same client closes with you.
  • It complied with the contract and you sold to someone else during the exclusive term. Here the penalty clause usually applies.

The practical rule: the agency earns commission when there is a causal nexus between its work and the sale.

How to terminate step by step

  1. Read the contract in full: term, exclusivity, penalty clause, protection period.
  2. Identify the applicable termination ground.
  3. Send a written termination letter, ideally via certified delivery or notarial letter, with copy to the email registered in the contract.
  4. Request the return of keys, plans, documentation and, if any, the list of prospects that visited.
  5. Ask for the listing to be removed from portals (Inmuebles24, Vivanuncios, Lamudi, Mercado Libre Inmuebles) and screenshot as proof.
  6. If the agency refuses, raise the dispute through mediation before a professional association (AMPI, Concanaco, etc.) or, in CDMX, before PROFECO if the agency is a franchise.
  7. As a last resort, civil lawsuit for contract termination.

Penalty clause: how enforceable it is

The penalty clause is valid but not absolute. Courts have reduced penalty clauses:

  • When they are disproportionate to the actual harm.
  • When the agency does not show real activity during the term.
  • When the contract was not properly disclosed to the owner.

A penalty clause of 5 % of the property value is generally valid; one of 100 % of the commission for simple revocation, without proven activity, is usually moderated.

Before signing the next contract

  1. Ask for short terms: 3–4 initial months, renewable by agreement.
  2. Limit exclusivity geographically or by buyer type.
  3. Define agency obligations: portal listings, photo sessions, minimum number of visits, monthly reports.
  4. Cap the protection period at 60–90 days after the contract ends.
  5. Ask for bilateral penalty clauses: if the agency breaches, it also pays.
  6. Keep the version signed by both parties and an inventory of keys and documents handed over.

Real case

A seller in Querétaro signed an exclusive agreement for 12 months with a 100 % commission penalty for termination. After 4 months, with no visits on record, he ended the contract by notarial letter on the grounds of breach. The agency sued. AMPI mediation: the charge was reduced to 30 % and, after verifying the absence of portal listings, the agency eventually withdrew.
