MLS Cooperation Regulation

The operational rules of sharing: who does what, who is paid what, and what happens when there is disagreement.

Approved by the General Assembly · In force since 15/05/2026 · Version 1.0 · Applies to all listings shared on the MLS

Sharing only works if the rules are the same for everyone and known before the deal. These rules bind any member who publishes or works a listing on the MLS.

The roles in sharing
Owner
Hires the listing agent

Signs the agency contract, authorises publication on the MLS and sets, with the listing agent, the fee offered to the buyer's agent. May ask in writing for the listing not to be published.

Listing agent
Represents the seller

Holds the agency contract, is responsible for the accuracy of the listing, sets the fee offered to the buyer's agent together with the owner and keeps the information current.

Cooperating agent
Represents the buyer

Presents the property, handles the offer and due diligence, and does not contact the seller directly without the listing agent's consent.

Buyer
Is supported by their own agent

Views, offers and negotiates through the agent they chose, who handles the offer and due diligence. Contact with the seller always goes through the listing agent.

Core rules

01
Explicit fee offer

A listing may be published on the MLS without sharing. When it is shared, it states the percentage or amount offered to the cooperating agent — no stated offer, no sharing.

02
The split is negotiated, never imposed

APMLS does not set, suggest or standardise commissions. Each member freely sets its own prices.

03
Publication deadline

Listings are uploaded to the MLS within 48 working hours of signing the agency contract, unless the owner instructs otherwise in writing.

04
Status updates

Reserved, sold or withdrawn is updated within 24 hours. Stale listings are removed.

05
Procuring cause

The cooperating fee belongs to whoever was the uninterrupted procuring cause of the purchase — not merely whoever showed it first.

06
Viewing record

Each viewing is logged in the MLS with date and cooperating agent. This is the evidence in a dispute.

07
Third-party advertising

A cooperating agent may only advertise another member's listing with written consent, always identifying the listing agent.

08
MLS data

MLS information is for the practice of brokerage. Bulk extraction or resale to third parties is prohibited.

🕐 Nothing here limits any company's freedom to set its own prices. Any attempt to agree commissions between members is grounds for immediate expulsion.
