With the increase in the practice of buyer agency in North America, especially since the late 1990s in most areas, agents (acting under their brokers) have been able to represent buyers in the transaction with a written "buyer agency agreement" not unlike the "listing agreement" between brokers and sellers (often referred to as a sellers agency). The real estate licensee, upon entering into a written agreement with a buyer, agrees to work solely for the buyer and in return, the buyer agrees to exclusive representation.
