Cooperating Broker

A cooperating broker (or "buy-side broker") represents the buyer in a transaction. Listing broker typically splits commission with cooperating broker — creating incentive to broadly market to other brokers.

What it means in practice

In a cooperating transaction, the listing broker represents the seller while the cooperating broker represents the buyer. Both brokers share the commission (typically 50/50 or negotiated). This arrangement broadens buyer reach for the seller at no additional cost.
