This Precedent is a short form letter of variation intended to be used in situations where: • there is an existing contract between two or more parties • the parties, by consent, wish to change certain provisions of the contract (whether to delete, amend or add further provisions) • there are no provisions within the existing contract which permit the change of some or all of its provisions without entering into a written form of variation, and • the parties are satisfied that there is consideration for the variation and so do not need it to be effected by way of deed The existing contract should be reviewed for any provisions dealing with how variations can be made. Even if the existing contract permits oral variations (which is unusual), the parties should document the change in writing.
