According to the theory, through their social interactions, people engage in obligations relating to actions to be taken and agree on the results of these actions [3]. This is done via acts of coordination through language that can be understood as issuing a sentence seen as an action. In this case, the act is called a performative utterance of contractual act and it creates new facts or actions or parts of an action. By stating the act, the announcer does not describe or even state the performing of an action. He is really performing it.
