In the sphere of contract law, good faith is the logic of trustworthiness whose precise and logical position is considered a basic principle in different stages of contracts, beginning with contract conclusion, implementation all through interpretation (Dawkins, 2014). At every stage of a contract, special behaviors and rules are necessary for complying with good faith. In achieving an agreement, preliminary talks and pre-contractual negotiations are inevitable. During this stage, parties to the contract engage in negotiations that are aimed at concluding a contract at the end. As such, parties must put on utmost good faith depicting no self-interest motives while at the negotiation process so as no party doesn’t end up incurring any undesired loss in the negotiation process.
However, given the great prominence in the pre-contractual negotiations, there is a lacking detailed analysis of good faith, especially under a distinct title. It has received a mere and brief discussion in conjunction with other subjects. Meanwhile, the good faith principle has received a more detailed discussion in states that follow the transcribed legal system, particularly because the principle in these states has been acknowledged as a mandatory principle (Quagliato, 2008). In Indonesia, the principle of good faith has received attention under other topics, and only a few aspects of the principle in negotiations and the conclusion of contracts have been highlighted. This is mainly attributable to the fact that the good faith principle is not explicitly taken care of in the legislation.
