Moroccan law seems to limit the principle of "force majeure" to the sole non-performance of damages. In all cases, the defaulting party bears the burden of proving its liability. However covid-19 has created confuesion and inconsistance on exeqution of force majeure of internatioal contracts. Thus, the objective of the stusy is describe and anlyse how Covid-19 global state of health emergency affect performance of contractual obligations of international contracts in Morocco. Morover to assess to what extent can international contract be adapted to the test of covid-19 per the provisions of Moroccan law. The research employed observation method which is an exploratory type of research approch that collect relevant information and data through observation to describe and anlyse how Covid-19 global state of health emergency affect performance of contractual obligations. The study found that Moroccan law does not have an explicit legal framework for contract negotiations, but could provide a basis for sanctioning an abusive termination of negotiations which is evedent during the covid-19 case. In addation" Dahir" (executive decree by king ) which describes obligations and contracts, did not take into account the theory of hardship. Therefore, besed on the findings It is recommended to stpulate explicit legal framework for contract negotiations to integrate various impacts, particularly in terms of deadlines, in the contracts to be concluded. Moreover, inclusion of new Dahir to embrece the theory of hardship which alows revison of binding force (force majeure) of the contract during hardship time such as Covid-19. Making such changes would help for effective exicution of contractual concept of force majeure in the time of C-19 to effective decide approprate combination of suspension of performance, exemption from liability for non-performance or termination of the contract.
