Signing a contractual written document normally indicates agreement and incorporates the terms contained within it even if they have not been read or understood by the person signing it, L’Estrange v Graucob. However, the parties will only be bound if what was signed was a contractual document otherwise the signature will not incorporate the terms; Grogan v Robin Meredith, eg a delivery note. There is also an exception where the person seeking to rely on the clause, misled the other party about the meaning of the clause, Curtis v Chemical Cleaning and Dyeing Co. This show that an oral statement can override written terms.
