Concept, effects and evaluation of the principle of contract maintaining

The principle of maintaining contracts is one of the initiatives of Prof. Jafari Langroudi, who is in a position to state that the custom of habit requires that a broken or violated contract be maintained and repaired. The scope of the principle of contract maintaining is wider than similar institutions such as the pacta sunt servanda (principle of necessity), principle of correctness and the theory of contract management. It includes the stages of conciliation, the execution of contracts and options, even unilateral legal acts and revocable contracts. The theory of contract maintaining seems useful in that it has a general scope and includes instances that are not covered by other legal institutions and rules. The civil law has also chosen a solution that is in line with the principle of retaining contracts; Such as option in sales unfulfilled in part and option of unfulfilled conditions. However, there are several cases in which the legislator and jurists have chosen different methods and strategies and should reflect on the effects of this principle and its compliance with civil law, the economic results of maintaining contracts and their acceptance by custom.
