This type of agreement emphasizes the same value of the goods or services offered by each party of the other. The legal definition of counterparty is based on the concept of „negotiated exchange”. This means that both parties get something they have accepted, usually something of value for something of value. Unscrupulous agreements can be evaded when a person has been coerced or unduly influenced or has taken advantage of their vulnerability when they have allegedly accepted an agreement. Children, persons with mental disabilities and businesses, whose representatives act outside their powers, are protected from having agreements imposed on them if they do not have the real capacity to take a decision on the conclusion of an agreement. Some transactions are considered illegal and are not enforced by the courts under any law or public order. In theory, English law strives to uphold a principle that people should only be bound if they have given their informed and genuine consent to a treaty. Large organizations with hundreds of countries as members also regulate cross-border trade. For example, the World Trade Organization (WTO) and its predecessor, the General Agreement on Tariffs and Trade (GATT), established rules on tariffs on the import and export of goods between countries. .
