Some of the best domain brokers regularly do co-brokerage deals. This means that more than one domain broker from different brokerages is working on selling a domain name. Domain owners need to be aware of the potential for co-brokered deals when they agree to sell a domain name with a domain broker.
There are benefits to a setup like this. The domain owner would get the benefit of having multiple brokers working their connections to close a deal. Different brokers and different brokerages work with different segments of the domain buying market. Some brokers are experts when it comes to dealing with Asian domain buyers. Some brokers are well connected with huge multinational corporations. Most top brokers have cultivated lists of domain name buyers. Having more than one domain broker working within their area of expertise can widen the net to find a buyer.
Even when more than one domain broker is working on a domain deal, the domain owner typically pays the same commission rate. It seems like a win win situation to have more than one broker trying to sell a domain name.
I do see one downside to this type of deal. A domain owner could agree to work with one broker exclusively and the broker, unbeknownst to the owner perhaps, agrees to split a commission to work with a co-broker. This can be problematic if the domain owner isn’t comfortable with the co-broker. In addition, if the original broker doesn’t sign a comprehensive agreement with the co-broker, the co-broker could theoretically go rogue and put the domain name at risk (ie emailing a trademark holder or acting in an unprofessional manner).
On the rare occasion that I choose an exclusive broker, I have done so after doing my due diligence. I would not be comfortable with a broker agreeing to co-broker one of my domain names without my permission.
Some of the top domain brokers and brokerages allow co-brokered deals. If this is something you’re not comfortable with, you should make sure the broker knows about this prior at the outset of your working relationship.
