In practice, the parties can obtain agreement by including in their agreements a language indicating that an electronic or digital signature or data set has the same effect as a wet signature or a physical record. In a commercial contract, the common word is as follows: in addition, in 400 George Street (Qld) Pty Ltd v BG International Ltd  QCA 245, it has been established that the performance of a document in the form of a document itself does not involve delivery, unless it appears that performance was intended as a delivery (delivery can be inferred from any fact or circumstance), including words or behaviours). In 400 George Street, the Court of Appeal ruled that the performance of a document by a proposed tenant did not constitute a delivery, as it should only be bound when all parties performed the deed, which was demonstrated by the original tenancy agreement, which was stated as the subject of a «mutually agreed legal document.» No no. The parties to an agreement could effectively execute a document using different methods; For example, a party that signs electronically, and a second with a wet ink signature. A compound version could then be created, either by using an electronically signed print of the page with the pages signed in wet ink, or by scanning the wet ink pages to add them to the electronically signed page. If this document were to be presented in evidence at a later date, an English court would accept the compound version. – An agreement must have a counterpart that goes from one party to another while it is on a document that is not necessary. One of the distinguishing factors in the performance of a document in relation to a contract is that a document must be «delivered». Delivery shall fix the date from which the performing party is bound by the document and, after service, a document without an explicit right of withdrawal is irrevocable. Under customary law, a document is issued when a party expresses its intention to be bound to the act, even if it remains in possession of the document. As Adams points out, this is problematic. First, because it is not clear why they used execution rather than signature.
Second, because the wording seems to indicate that delivery is necessary for an effective contract, but that waterproofing and delivery are not really the prerequisite for all contracts. For the validity of an informal contract, a writing is only necessary if at least one of the parties has sufficiently expressed the intention not to be bound without a contract. In this case, the agreement must be in writing and this writing must be submitted to that party for approval. . If the reduction of the agreement on the written form is necessary, the approval of the writing must also be considered sufficient. This event usually consists of signature and delivery. This explains why, in many cases, it was felt that the letter should be provided. It is perhaps true that the mere reading of the conditions of a scripture is not a manifestation of the consequenceation to them. Even the appeasement of the signature and the continuation of the possession of the paper can not express a guard-pass.. . .
