This article examines challenges and proposes legal solutions for the enforcement of contracts especially after the transformation of the economy following Covid-19 and related governmental measures that have swept throughout the world since December 2019. Maximising the role of the judge and increasing the contractual parties’ involvement in phases of contractual disputes constitute the core of this research. This article argues for strengthening the contractual guarantees by advocating for the use of the two contract doctrines of force majeure that normally lead to termination of contractual obligations, and changed circumstances that may trigger intervention of the judge to lift the economic burden of the debtor and reach a fair solution. This article also argues for adopting a more flexible approach to the application of the doctrine of change of circumstances during the performance of the contract that not necessarily relies on this traditional distinction between force majeure and hardship.

本文探讨了合同执行面临的挑战并提出了法律解决方案，特别是在 Covid-19 和自 2019 年 12 月以来席卷全球的相关政府措施之后的经济转型之后。最大限度地发挥法官的作用并增加合同当事人的参与合同纠纷的各个阶段构成了本研究的核心。本文主张运用不可抗力两种合同原则来加强合同保障这通常会导致合同义务的终止，以及可能触发法官干预以减轻债务人的经济负担并达成公平解决方案的情况发生变化。本文还主张采用更灵活的方法来适用合同履行期间情势变更原则，而不必依赖于不可抗力和困难之间的这种传统区别。
