IL Designated Agency & Agency Disclosure

Prior to the year 2000, real estate transactions in Illinois were entangled in the invisible, often contradictory webs of common-law agency. Under the old rules, if a buyer walked into a brokerage to look at a listing, the agent showing the home was legally considered a subagent of the seller—bound to fetch the highest price for the seller, even while smiling and shaking the buyer's hand. It was a labyrinth of implied loyalties that left consumers bewildered and brokers legally exposed.

The Illinois Real Estate License Act of 2000 incinerated this confusion. The Act completely replaces common-law agency with statutory rules under Article 15. The old concept of subagency is legally prohibited in Illinois. Instead, the law establishes a clean, precise, and highly individualized framework: you represent the person you are actually working with, and the rules of that relationship are etched directly into the statute.
