There are legal requirements for the awarding and variation of contracts, which are not always obvious to the uninitiated. It is worth using professional advice if you want to make sure that your contract or modification is legally applicable. Having to prove a contract change in court is an expensive procedure that can be avoided at best. However, a contract may be modified by a verbal agreement or by the conduct of its parties, even if the contract itself contains a “no oral amendment” clause. This position was recently clarified and confirmed by the Court of Appeal in a case between Globe Motors and RW Lucas Varity Electric Steering Ltd. This position was then consolidated in a case later in 2016 between the status of company operating under the conditions of a market economy business exchange centers and rock advertising. 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. Changes to a construction contract are usually made by written agreement between the parties and are changes to the contractual provisions that do not include the scope of the work to be done. 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. Contractual guarantees are less important conditions and are not fundamental to the agreement. They cannot terminate a contract if the guarantees are not fulfilled, but they can claim damages for the losses incurred. The judge introduced the legislation with respect to the modification of the contracts. A contract can be amended by agreement between the parties by adding, omitting or changing certain conditions. To be effective, the amendment must contain all the elements necessary for the law for an enforceable contract. One of these elements is the intention of the parties to be related to the variation. The responsibility for showing an intention to be bound rests with the party claiming that there has been a variation.
