Subagency

Imagine a master architect who is contracted to design and build a skyscraper. The architect cannot pour every cubic yard of concrete or weld every steel beam alone, so they hire specialized contractors. In the eyes of the project owner, those contractors are an extension of the architect; they are legally bound to build the owner's building and advance the owner's goals, even if the owner never shook their hands.

In New York real estate, this architectural delegation is called subagency. When a homeowner hires a listing broker, that broker often enlists the help of outside agents to find a buyer. This creates a chain of command where a cooperating agent from an entirely different brokerage is deputized to act on behalf of the seller. The legal implications of this chain—who is responsible for whom, and who owes what to whom—form the structural bedrock of modern real estate transactions. Understanding these mechanics is not merely about passing a licensing exam; it is about navigating the daily reality of open houses, offers, and liability without exposing yourself, your broker, or your client to ruinous lawsuits.
