This document discusses transaction brokerage and agency relationships in real estate. It begins with background on how brokerage relationships have evolved from caveat emptor to offering choices. It then covers key questions about agency and transaction brokerage. Finally, it discusses how different states handle agency, either making it automatic or allowing it only by written agreement. The overall message is that brokerage relationships can be simplified to two roles - exclusive service or impartial service - and two relationship types - transaction broker or agent.
