An attitude towards the condition of the act of negative law in the contracts of Iranian legal laws

In contract law, the condition is referred to as the institution that derives its main effect from the contract in such a way that the effect of the contract and the condition are reflected in each other. When concluding a contract, the parties to the contract pay attention to some of its principles and try to impose certain conditions and rules while concluding the contract. Or refuses to do so at all and changes his contract when he violates this relationship and commitment. In this regard, different views have been expressed that some believe that the contract is terminated and there is no need to force the obligee and some believe that in the first stage the obligee should be forced, so in this study we try to place the negative verb in Iranian and Egyptian law. Let's discuss the reason for examining the rights of Egypt because this country is very similar to Iran in terms of jurisprudence and law.
