Effects of the option agreement on Iranian and French law

An option contract is a type of pre-contract and a derivative instrument. Despite the fact that this contract is known and very efficient in the world market, but it is an emerging contract in Iran and one of the reasons for not using it is not recognizing the effects of the contract. Therefore, in this research, which has a completely practical aspect, the effects of the contract of option in Iranian law and French law as one of the most prominent legal systems in the world have been discussed.The effects of certain contracts are defined by the legislature, but there are also effects that are essentially common between contracts, both definite and indefinite. On the other hand, due to the unique nature of the contract, the option to trade the effects of this contract before the exercise of the right and after the exercise of the right is different. Also in discussing the effects of the contract, we are faced with the issue of the relative principle of the effects of the contracts and its exceptions.
