In English law, incorporation of terms refers to the process by which contractual terms become legally binding parts of a contract, whether expressly agreed or implied through conduct or context.
Courts examine clarity, timing, prominence, and the nature of terms—particularly exclusions or limitations of liability—to ensure fair notice and consent.
Failure to properly incorporate terms renders them unenforceable, potentially exposing parties to unanticipated liabilities or obligations.
Effective incorporation ensures clarity, predictability, and enforceability, protecting parties’ expectations and commercial interests.
AEG sought to make Logic collect defective goods from Hong Kong. By majority, the Court of Appeal held that such a worldwide collection obligation was onerous and unusual and had not been sufficiently brought to Logic’s attention, so it was not incorporated into the contract.
A dragline crane hired urgently by the defendants sank into marshy ground without fault from either party. The Court of Appeal held that standard trade conditions were incorporated into the oral contract due to both parties' knowledge of such conditions in the plant hire trade, making the hirer liable for recovery costs.
Mr Hollier's car was damaged by fire at the defendants' garage due to their negligence. The defendants sought to rely on an exclusion clause disclaiming responsibility for fire damage. The Court of Appeal held the clause was not incorporated by course of dealing and, even if it had been, did not effectively exclude liability for negligence.
A photographic library sent transparencies with conditions including an unusually high holding fee of £5 per day per transparency. The defendants retained them beyond 14 days without reading the conditions. The Court of Appeal held that particularly onerous or unusual terms must be fairly brought to the other party's attention to be incorporated into a contract.
Warehousemen stored barrels of orange juice which were returned damaged. The customer counterclaimed for negligence, but the warehousemen relied on an exemption clause in their contract conditions. The Court of Appeal held the exemption clause was incorporated through course of dealing and protected against negligence, provided there was no breach of a fundamental term.
Mr McCutcheon's car was lost when the respondent's ship sank due to negligent navigation. The carrier sought to rely on exclusion clauses from previous dealings, but no risk note was signed on this occasion. The House of Lords held that previous course of dealing cannot incorporate terms into a contract where no contractual document was used on the relevant occasion.
Tekdata and Amphenol disputed whose standard terms governed contracts for connectors used in Rolls-Royce aero engines. The Court of Appeal held that the traditional offer and acceptance analysis applies in 'battle of forms' cases, meaning the seller's terms on the acknowledgement prevailed unless conduct showed contrary common intention.
A professional trumpeter was injured at an automatic car park. The parking company sought to rely on exemption clauses displayed on premises and referenced on a machine-issued ticket. The Court held that contractual terms from an automatic machine come too late if issued after the contract is formed, and unusual exemption clauses require explicit notice.
In a 'battle of the forms' dispute, TRW purchased goods from Panasonic. The Court of Appeal held that TRW's conduct in accepting delivery of the goods constituted acceptance of Panasonic's counter-offer, thereby incorporating Panasonic's standard terms, including a German jurisdiction clause.
