The MLS BCS Standard Listing Agreement, officially registered with PROFECO, includes a mandatory escrow clause ensuring commissions are paid directly from escrow at closing — protecting agents every time. It also features a Mediation & Arbitration clause backed by the MLS's newly launched dispute resolution center, offering a faster and more reliable alternative to Mexico's court system.

The MLS Subdivisions system requires developers to submit key legal documents — including a Construction License — before listing any new project, with inventory minimums and a $500 fee launching in 2026. Projects without a construction license are limited to "Reservations Only," and commissions are paid directly from escrow upon signing the promissory agreement.

The MLS is tackling "bad developers" in the market by launching a 1–5 star rating system in 2026 to evaluate projects based on legality, documentation, and reliability. Low-rated developments may be removed from the MLS, promoting transparency and protecting both buyers and agents.
