Where a buyer cooperates with a sub-agent, he or she is not represented by any of the real estate licensees participating in the transaction. Both the listing agent and the sub-agent represent the seller, while the buyer does not remain represented in the real estate transaction. However, there was no such agency relationship with the buyer and the broker`s agents assisted the buyer (normally known as his «client»).
