What else do I need to know?
The parties to a contract may negotiate new or different terms for their agreement. This might be due to a change in circumstances which result in the parties agreeing new terms or perhaps a change which is negotiated as a consequence of one party not being able to comply with the original agreement.
This document is an agreement pursuant to which the parties agree to amend specific terms of their agreement. It is suitable for a contract which is governed by English law. Going forward, the original agreement and the amendment agreement will, together, comprise the form of the agreement.
An alternative to having two documents going forward (with the possibility of there being additional documents if further changes are made) would be to replace the original contract in its entirety but in its amended form. This is achieved by amending and restating the original contract by entering into an “amendment & restatement agreement”.
