When two parties have entered into a contract, one party cannot unilaterally change the terms of the agreement. However, it is common during an agreement for parties to agree to a variation to the terms of the original agreement. A variation must fulfil the requirements governing the formation of a contract in order to be legally enforceable and a variation can only be made in respect of obligations of one of the parties which are as yet unperformed.
