When a contract is concluded between two parties, one of them is faced with a situation where they must either accept the contract in its entirety or reject it without the possibility of negotiating its various terms. However, it is important to note that the party proposing the contract is obligated to fully inform the other party, in accordance with Article 1109 of the Civil Code, which stipulates that all consent must be given freely and knowingly, without error, duress, or deception.
