Commentary on Sections Part 5 - Provisions Applying Only to Secure Contracts Chapter 2 - Variation of Contracts
278.A variation of a contract is a change to the terms of the contract which is made after the contract comes into force. A ‘variation’ is defined in section 247, and includes the removal or addition of terms as well as the amendment of existing terms. Any change to the identity of the landlord or the contract-holder is not a variation (this is dealt with under section 40).
