Sub-agent (Sub-agency) is a real estate term in the United States and Canada describing the relationship which a real estate broker and his/her agents have with a buyer of a business, home, or property.
[1][2] Lasting until the early 1990s, the broker provided a conventional full-service, commission-based brokerage relationship under a signed listing agreement only with a seller, thus creating an agency relationship with fiduciary obligations under common law in most of the US and Canada.
In this situation, during the entire period in which the buyer looked at properties, entered into a real estate contract, and finally closed on one, that broker/agent functioned solely as the sub-agent of the seller’s broker.
[6] In the Philippines, a Sub-Agent is someone who is under the supervision and operational control of a Real Estate Broker.
The formal position of a Sub-Agent in the hierarchy of real estate practitioners in the Philippines is equivalent to the rank of Salesperson.
