A seal is a figure impressed on a document to validate it (see: Instrument under seal). Formerly a seal would have been an impression on wax; these days it is usually made on a paper wafer. In Britain the use of seals is on the decline, but this does not mean that the execution of a deed (see: Deed) has less force. For example, the Law of property miscellaneous provisions act (1989) removes the requirement for sealing in certain transactions that previously required it, but indicates the form of words that should be used to convey that the transaction still has the strength and formality of a deed under seal.
