Michael listed his house for sale. A contract for sale was signed with a buyer and provided for earnest money to be held by Barb, the listing broker, as "escrow agent." When the sale failed to close, Michael demanded that Barb return the earnest money to him. Barb refused because the buyer disputed Michael's right to the money, and Michael brought suit claiming that Barb had an agent's duty not to dispute her principal's claim to the funds. Court should rule for Michael. True or false
