In Mitchell Realty Group, LLC v. Holt, 266 Ga. App. 217 (596 SE2d 625) (2004), a broker filed suit to obtain a brokerage commission allegedly owed it by a party who had agreed to purchase real property by executing a purchase agreement, but then refused to close on the real property transaction. After noting that the case was governed by Georgia's Brokerage Relationships in Real Estate Transaction Act (BRRETA), the Court determined in Mitchell: The legislature clearly intended that agreements between a broker and its clients regarding the amount of brokerage compensation be placed in writing.
