If the representer has specialknowledge, the statements they make are more likely to be relied on and so may be part of the contract Dick Bentley V HSM
If there is a longgap of time between the statement and the agreement, it suggests the statement wasn't very important and should not be part of the contract. Routledge V Mckay
exception, Written statements only apply to contactual documents
Gorgan V RobinMeredith the rule from l'estrange only applies to contractual documents.signing a non-contractual document will not automatically incorporate those terms.
when there is any information outside/in place of a written contract, we need to see if this has been incorporated based on how clear this information was
newspaper had done enough (taken reasonable steps) to let readers know there were rules and that they could find out = D took reasonable steps to let C know of the exclusion
shows that the more unreasonable the exclusion clause, the clearer they must be. It also shows the terms must be clear when making the contract, not afterwords.
