Terms can be incorporated through 1) a signed document, 2) adequate notice which considers timing, type and nature of the document, 3) a consistent course of dealings as shown in Hollier v Rambler Motors, or 4) the common intention and understanding of the parties such as in British Crane Hire Corporation Ltd. v Ipswich Plant Hire Ltd. The document discusses four ways that terms can become legally binding: through a signed document, adequate notice of terms in the document, a consistent course of dealings between the parties, or a common understanding between the parties.
