Shared exclusive listings between agencies in Spain: how they work

Published 27 September 2026

A shared exclusive is the arrangement where the agency holding the owner's exclusive mandate lets other collaborating agencies sell the property too, splitting the commission. An MLS such as PropertyList makes that step easier: the listing goes up once, with the commission split set on the listing itself, and every registered agency can see it.

The difference from a non-exclusive instruction

With a non-exclusive instruction, the owner gives the property to several agencies with no collaboration agreement between them. Each agency works it alone, finds its own buyers, and splits nothing with the others.

With a shared exclusive, one agency holds the owner's mandate, and it sets the terms of the collaboration, starting with the commission split. If a collaborating agency brings the buyer, the commission is split between the two agencies.

What is worth putting in writing

Even with the terms on the listing, the two agencies should confirm in writing, before the buyer is introduced:

• the property and the listing terms that apply to this deal,
• how the commission splits if the sale closes,
• who handles the owner and who handles the buyer through the process,
• how long the agreement holds.

It does not need to be a long document. Both agencies having the same signed page, or the same confirmed email, is enough before a buyer is introduced.

Where the commission split is set

On PropertyList, the agency that lists the property sets the commission split on the listing itself, and other agencies see it before they market it. Nobody has to ask for it or negotiate it again with every interested agency. Outside an MLS, the split is agreed between the two agencies, usually as a percentage of the total sale commission.

How an MLS turns this into one step

Without an MLS, every shared exclusive means negotiating collaboration agency by agency: calling, sending the listing sheet, agreeing the split, then repeating it with the next interested agency. On an MLS such as PropertyList, the listing goes up once and every registered agency can see it, with the terms already set. If you would rather no other agency marketed it, you can mark it private: it leaves the MLS and stays on the public portal. The first five private listings are free; after that, 5 credits each.

Frequently asked questions

What is a shared exclusive listing between agencies?

It is the arrangement where the agency holding a property's exclusive mandate lets other collaborating agencies sell it too, splitting the commission if one of them brings the buyer.

Do I need a contract for a shared exclusive?

Put it in writing: which property is shared, how the commission splits, and how long the agreement runs. It does not need a long contract, but it does need something signed or confirmed by email.

Does an MLS replace the agreement with the collaborating agency?

Not entirely. On PropertyList the commission split is already set on the listing, but the two agencies should still confirm in writing who handles whom before the buyer is introduced.
