In the whirlwind of the economy, written agreements sometimes cannot follow trade developments; and when disputes arise, the parties may find that their contracts do not say what they thought or reflect their actual practice. This can be frustrating and create uncertainty – are the parties bound by their initial agreement or has the treaty been amended? The VAF met the contractual condition that the amendments must be signed in writing and signed by the parties, and then, once the amendment was made, the GDS contract (in its different version) was governed by the entire contractual clause. In this article, we look at how a contract may vary and the factors that will be considered by the courts in determining whether a meaningful change has taken place. 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. Now, the parties may have more confidence that the courts are likely to maintain this provision if their contract says it can only be amended in writing. However, there may be limited exceptions where one party relies on the other party`s assertion that an oral amendment is valid regardless of the existence of such a clause. In such cases, the Estoppel doctrine may prevent the party from “modifying s.a.” – The application of the clause.

In the construction industry, where oral instructions on variation in the extent of order work are common, parties should ensure that these oral derogations are subsequently confirmed in writing. Do not assume that, simply because both parties agree to something orally and then fulfill the contract in accordance with that agreement, they have waived the right to invoke the formalities of the written agreement. As always, there are exceptions to the rule. For example, the law requires that certain types of contracts be entered into in writing. Derogations from these contracts must therefore also be made in writing. Examples include contracts for the sale of land, the transfer of a contract, guarantees and the transfer of intellectual property rights. In addition, the parties` initial agreement may expressly state that it can only be different in writing (see below).
