This decision may be based on a number of considerations; However, it is important to reflect on the binding effect of the act. The nature of a document is that it is binding on the manufacturer as long as it has been signed, sealed and delivered – even if the parts have not been replaced. In this sense, an act is often used by parties: on the other hand, if I promise to give you a car and you do not promise me anything in return, the promise against me would be enforceable. Under these conditions, a court could force me to give you the car I promised you. On the question of whether a document is an act or an agreement, the courts have concluded that the person performing the act intends to engage him immediately. In 400 George Street (Qld) Pty Ltd v BG International Ltd  QCA 245, the Queensland Court of Appeal found that the words used in the document “exported as an act” and “by the performance of that act” clearly expressed the intention that the document was an act and not an agreement. Such extended limitation periods should be taken into account in the decision to execute a document in the form of an agreement or instrument. Other considerations relating to the decision to execute a document in the form of an agreement or deed are as follows: although consideration is not strictly necessary when a commitment is included in an act, it is still customary for at least one nominal amount of the consideration to be included in documents. This is due to the rule that own funds do not help a volunteer. . . .
