Negotiation is a given and a precursor to concluding contracts in general, since it is not possible to reach a contract agreement without exchange of views and consultation with a view to reaching such an agreement, and the value and importance of the negotiations have increased in the present era due to the increasing images of modern contracts, which requires some clarification on the conduct of the parties on their rights and obligations among each other, as the negotiations represent the real mirror to clarify the contours of the next decade on it by its parties, since the endurance of commitment is as severe as it can face if a person is vague during the preliminary agreement "negotiations", and before the contract is held.
