Amending clauses establish an agreed method by which changes are agreed (they are sometimes referred to as “contract amendment clauses”). A concession granted by one Party to the other Party for reasons of convenience and at its request therefore does not constitute an amendment. In the absence of such consideration, a derogation may be made by document. The purpose of an amendment clause is to prevent attempts to undermine the written agreement by informal means and to avoid disputes over whether a change was planned and its exact terms. Such clauses are often found in commercial contracts, and in the 2018 Rock Advertising case, the courts confirmed that the law will enforce these clauses. In most cases, a commercial contract contains an explicit clause specifying whether one or more of the parties to the agreement can change their terms and what procedure must be followed to amend the contract – for example, whether an amendment must be made in writing and signed by all parties. Unless the law or the contract itself provides otherwise, the contracting parties may amend it by oral or written agreement. Another contract – new – is needed to modify an existing contract: known as variation. The Court of Appeal ruled that TRW had not violated the agreement. It was therefore not absolutely necessary for the Tribunal to consider the point of the amendment clause. However, as there were two competing decisions of the Court of Appeal on this point, the Court of Appeal took the opportunity to do so in an obiter decision. Simply put, a contract change occurs when the parties agree to do something different from what they originally agreed, while the rest of the contract otherwise operates unchanged.

If this type of clause appears in a contract, trying to change it in a conversation is not legally effective. Verbal changes are excluded. When the parties amend a contract in writing, it is usually easy for a party asserting their rights to prove the agreed change by referring to a change agreement or exchanging emails. Similarly, a party making an oral amendment should be able to see how the amendment agreement came into being. However, if a party claims that a contract has been altered by behavior, things can be a little more complex. The Court of Appeal upheld the general principle of English contract law that the parties are free to agree on the terms they choose, whether in a document, by word of mouth or by conduct. This is subject to certain common law restrictions, such as penalty clauses and trade restriction clauses. There were no common law restrictions on the clause in question.

The fact that an agreement may contain an amendment clause does not prevent the parties from entering into a new contract which modifies that contract by oral agreement or conduct. However, a contract may be modified by an oral agreement or by the conduct of its parties, even if the contract itself contains an “oral non-derogation” clause. This position was recently clarified and upheld by the Court of Appeal in a case between Globe Motors and RW Lucas Varity Electric Steering Ltd. This position was later consolidated in 2016 in a case between MWB Business Exchange Centres and Rock Advertising. The law implements a contractual provision according to which certain formalities for amending an existing contract must be complied with. However, for this variant to be effective, there must be the following: An exception to this general rule is that a contract that must be required by law or proven in writing – for example, consumer credit or consumer leases – can only be amended in writing. Sometimes it is not only prudent, but essential to modify a written contract. Commercial contracts often contain a clause that provides that an amendment is only effective if it is made in writing and signed by all parties. This type of clause aims to strike a balance between flexibility and security. While this allows the parties to modify their agreement (giving them the flexibility to reflect subsequent developments and changes in practice), it means that the parties should always have a final record of the agreed terms (as they have varied over time) and thus avoid disputes over the terms that govern their relationship. Even if contracts contain clauses that allow a party to unilaterally change the terms of the contract, this also has its limitations.

The variant cannot make a new treaty completely different from the one that was already in force. Many commercial contracts contain a clause that expressly states that the contract can only be amended if the amendment is made in writing and signed by all parties (an amendment clause). The purpose of an amendment clause is to exclude the possibility that informal or even involuntary variations may be binding. Despite this wording, an agreement can in fact be amended orally or by conduct, as recently upheld by the Court of Appeal in Globe Motors Inc & others v. TRW Lucas Varity Electric Steering Limited et al. This distinction can be important – if the derogatory agreement differs substantially from the original contract, it can be considered by the court as a new agreement, so that the original contract will be annulled. This could have unintended consequences if a party wishes to invoke a provision of the original contract that may not have been reflected in the new agreement. In the absence of a modification clause, a modification of a contract can be made in any way that a contract can be concluded.

It can be varied: deviations from the execution of this work, on the other hand, are usually carried out according to a modification procedure specified in the terms of the contract. This is because construction projects are usually so large and time-consuming that it is administratively less difficult for the parties to agree in advance on a change procedure, so there is no need to amend the contract every time the scope of work changes. You may have seen clauses in a contract that state that the contract can be modified, modified and/or changed “as the parties may agree”. For example, in a contract for the delivery of goods, the parties may agree that the delivery time of the goods will be shortened by one week in exchange for an increase in payment, while the other conditions remain the same. Such an agreement, if valid, would constitute a modification of the existing contract. In the present case, the party arguing that the contract has been amended must prove that there was clear conduct that is inconsistent with the terms of the original contract and that is compatible only with the parties who agreed to amend those terms. In other words, a party will not be able to detect a change in behaviour if the parties would have acted or could have acted exactly as they did in the absence of such an agreed change. Therefore, it is often very difficult to determine that a contract has been modified by the behavior and therefore the parties are advised to record the deviations in writing in order to avoid disputes over the terms of their relationship.

Amendment clauses have value in promoting commercial security and avoiding false or frivolous claims in an oral agreement. However, where there is clear evidence of the facts of the case that a change has occurred and the parties have accepted it, the court should grant that deviation. Freedom of contract may mean that a party is unconsciously contractually bound to a party or provision that was never intended. In the business maelstrom, written agreements sometimes fail to keep up with business developments; And then, when disputes arise, the parties may find that their contracts do not say what they thought or do not reflect their actual practice. This can be frustrating and lead to uncertainty – are the parties tied to their original business or has the contract been changed? In the event of a dispute as to whether the parties have entered into a valid agreement to amend the contract, the court will decide the matter taking into account the relevant facts in the light of the usual rules of interpretation of the contract. Globe claimed that the agreement had been modified by conduct and that, as a result, Porto had become a party to the agreement. TRW argued that there had been no change, citing the amendment clause of the agreement, which provided that it could only be amended in a written document signed by all parties. There was no such document. However, as always, there are exceptions to the rule. For example, the law states that certain types of contracts must be in writing. Amendments to these contracts must therefore also be made in writing.

Examples include land sales contracts, assignment of the benefit of a contract, guarantees, and transfers of intellectual property rights. In addition, the initial agreement of the parties may expressly provide that it may only be amended in writing (see below). In addition, any agreement that amends the terms of an existing contract should either be justified by consideration or performed as an act in order to comply with the rules for concluding the contract. However, in many cases where changes must be made in agreement with the parties, the agreed changes may not be legally binding or enforceable unless there is a properly implemented change document – so it is important that the parties take into account the change requirements and implement the changes in accordance with the applicable contractual terms. This will reduce the possibility of lengthy and costly litigation in the future. Until recently, however, there was some uncertainty as to whether such clauses are binding. .
