Article 157 of Civil Code

1 - For duress to have effect, the fear that induced the contracting party to consent to the contract must have been instilled in him by the act of the other contracting party, his representative, one of his subordinates, a person he commissioned to act as intermediary, or the person in whose interest the contract is concluded. 2 - If the duress originates from a third party, the coerced contracting party may not seek annulment on that basis unless the other contracting party, upon concluding the contract, knew of it or must necessarily have been presumed to know of it. All this is subject to the provisions of the following article.
