I have long argued against Dual Agency, and need to slightly redefine/clarify my opposition – My beef is with Single Agent Dual Agency where the same agent represents both sides of a transaction. In principle and practice, Dual Agency, also known as Designated Agency, when practiced by agents in the same firm should be legal and ethical.From the Virginia code:”Designated agent” or “designated representative” means a licensee who has been assigned by a principal or supervising broker to represent a client when a different client is also represented by such principal or broker in the same transaction.”Dual agent” or “dual representative” means a licensee who has a brokerage relationship with both seller and buyer, or both landlord and tenant, in the same real estate transaction.
