Representing the buyer and the seller in the same transaction by the same agent. Since there is an inherent conflict in Fiduciary Duties to two different principals, Dual Agency, at best, is a risky undertaking. All states require that Dual Agency must be disclosed to all parties to the transaction. Also see Intermediary and/or Undisclosed Dual Agency is illegal in all states. Caution: This form of agency offers a reduced level of service and should never be considered unless you are very knowledgeable about real estate.
