There are certain areas in which the particular form of the contract must be respected, but in England the court tends to recognise the agreements of the parties. It can be seen that the general tendency in common law systems is to allow the existence of the treaty. What is a contract? A contract can be defined as an agreement between two or more parties (individuals or organizations) that creates obligations and rights, and these rights are legally binding on the parties. Depending on the nature of the treaty, the treaty must be written and signed in some legal systems to be legally binding, while in others, an oral agreement may even be considered the conclusion of a legally binding treaty. Four key conclusions can be drawn from the previous brief excursion into this area of developing law: as a rule, the explicit conditions are found in written contracts. In other words, when the parties enter into a written contract, all explicit conditions must be set out in this contract. . . .
