The term 'agreed form' is most commonly used to refer to an agreement that is ancillary to the main agreement, and that is not to be entered into by the parties until completion of the main agreement occurs. It may also be used in relation to documents that supplement an agreement and do not have contractual effect. This suggested definition states that the parties will agree with the form and content of such a document at exchange and such document should be initialled by, or on behalf of, the parties to show such agreement and identify it as being in the agreed form. It also allows the parties to amend any agreed form document between exchange and completion of the main agreement, by an agreement in writing. As such, this definition will only be relevant, as drafted, where there is to be a gap between exchange and completion of the relevant agreement.
