Therefore, this amendment agreement – a change in the terms of a contract proposal should be used when the parties to an existing contract wish to amend one or more provisions of a contract or agreement that have already been signed and are in force. In the event of a dispute over whether the parties have entered into a valid agreement to renew the contract, the Tribunal will rule on the issue on the relevant facts, taking into account the usual rules of interpretation of the contract. Reflection could take many forms, such as .B reciprocal abandonment of existing rights; The new benefits granted by each party to the other party; Make and/or release commitments. In the absence of consideration, there may be a change by deed. For example, in a freight delivery contract, the parties could agree that the delivery time of the goods should be reduced by one week in exchange for an increase in payment, while the other conditions will remain unchanged. Such an agreement, if valid, would constitute an amendment to the existing contract. As long as the law or the contract itself does not say otherwise, contractors can amend it by oral or written agreement. On the other hand, derogations from the performance of this work are generally carried out according to a method of variation established in the contractual conditions. Construction projects are generally so large and take so long that, from an administrative point of view, it is less difficult for the parties to agree in advance on a method of variation, so there is no need to amend the treaty each time the size of the work changes.
However, until recently, there was some uncertainty as to the binding nature of these clauses. Despite the clear wording of these variation clauses, they would have led to conflicting decisions of the English court. In one case, the Court of Appeal found that the parties could change their agreement orally orally or by conduct, even though the agreement expressly stipulates that the amendments must be made in writing. In essence, the Court held that, when they agreed orally to amend a substantial part of their agreement, the parties also tacitly agreed that the “written amendment” clause no longer applied. However, following a Supreme Court decision in May 2018, this approach is no longer a right.
