A gentlemen`s agreement is an informal pact between two parties, usually written orally or less frequently. It is essentially based on the assumption that both parties will respect the word given to their honour because, unlike a formal contract, it cannot be defended in court. But before the conclusion of the contract itself, there is a whole period that can have an indeterminate duration, during which the parties must be able to move and act with more flexible margins, compare and exchange opinions and ideas and define points and agreements, especially for the most demanding economic operations. , which are gradually being achieved and are a precondition for further negotiations and the definition of rules for the interests concerned. In this negotiating game, where it is important to be able to count on the possibility of creating and not fulfilling the conditions already agreed and verifying the points and results already achieved and perhaps already achieved, the parties must rely on dynamic and unsophisticated models of agreement, which are the only ones that can meet their expectations. Operators who have expressed an interest in implementing a given economic relationship must feel and be free to carry out all activities that prepare for the pursuit of the final objective, without too many legal constraints that often stifle the emotional dynamism of promotion and the acquisition of new economic opportunities. The approach taken by the parties at this stage is more prudent, less secure and more prudent; its progress is slow and questionable and in search of confirmation and feedback, and the order must respect its reservation by providing the parties with their tools, the “toolbox” that the parties use from time to time. Otherwise, the market would still suffer before the operators, as it would see development opportunities frustrated because of commercial and financial transactions which promote the circulation of wealth and the well-being of the Community and which, on the contrary, would be interrupted or reduced for fear of negotiations ordered by the legal order. In addition, the parties are led to turn to the order that can better meet their expectations than others, if they are able or know how to choose the most favorable law, in this case the least invasive rules.
