Parties in a negotiation typically use a letter of intent. Although in many cases buyers may proceed in negotiations with sellers using such letters of intent (stipulating only a few provisions that are intended to be legally binding like confidentiality and exclusivity), under Venezuelan law, these pre-contractual letters will not necessarily have a legal effect because whether or not a letter will create legal obligations depends on the substance of what is said and not its format. In the pre-contractual phase, the parties must act in good faith.
