Final answer:
A subagent in Texas real estate is an agent who collaborates with the listing broker to help sell a property, representing the seller's interests indirectly through the listing broker.
Step-by-step explanation:
Under the Texas Real Estate License Act, a subagent is an agent who is not directly associated or affiliated with the listing broker but has agreed to work with the listing broker to sell the property. Essentially, this means a real estate agent who works with the seller's agent to find a buyer for a property.
The subagent represents the interest of the listing broker and, by extension, the seller, but does not have a direct contractual relationship with the seller themselves.
