Furthermore, in 400 George Street (Qld) Pty Ltd v BG International Ltd  QCA 245[ 2010] QCA 245, it was established that the performance of a document in the form of an act does not itself involve delivery, unless it appears that performance was intended as delivery (delivery may be deducted from any fact or fact, 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.“ – An agreement must have a counterpart that goes from one party to another while it is on a document that is not necessary. When transferring real estate, a document transfers ownership from the previous owner (the concessionaire) to the new owner (the beneficiary) and may contain various guarantees. The exact name and nature of these warranties differ from jurisdiction to jurisdiction. Often, however, the fundamental difference between them lies in the extent to which the licensor guarantees title. Licensor may provide a general title warranty against claims, or the warranty may be limited to claims that have arisen after licensor has received the property. The latter type of act is generally referred to as a specific guarantee instrument. While a general guarantee instrument was normally used for the sale and transfer of residential immovable property, special guarantee instruments are increasingly used and are increasingly used in commercial transactions. In NSW, a document must be written for it to be enforceable. The subject matter of an act can be very different and concerns one or more of the following conditions: the United Kingdom, England and Wales keep a „cadastre“. Title deeds are documents showing ownership as well as rights, obligations or mortgages on the property.
