A real estate broker is a word in the joint States which describes a party who acts as an intermediary between retailor and buyers of real estate (or real property as it known elsewhere) and attempts to find sellers who wish to sell and purchaser who wish to buy.

Without a signed agreement, brokers may assist buyers in the attainment of property but still represent the seller and the seller's benefit.
In most jurisdictions in the United States, a person is required to have a license in order to receive salary for services rendered as a real estate broker.

In some states, lawyers are allowed to handle real estate sales for compensation without being licensed as brokers or agents.
