During this period of COVID-19 you may be phased with challenges of contractual non-performance due to Covid-19. Have a look at your contract and determine if there is any provision made for relaxation or exit as a result of non-performance. This pandemic known as Covid-19 can be classified under Force Majeure.
If your contract makes provision for Force Majeure you can enforce it as an excuse for your non-performance. From there consider re-negotiations, such as to extent your performance period and/or negotiate holiday payments.
Should you enter into a contract during this pandemic time or anytime thereafter, make sure not to sign a contract which does not cover a Force Majeure clause that protects you or your business against eventualities such as COVID-19.
