Does the contract have a force majeure clause? If so, your counterparty may well be within its rights to deny you possession. In any event, you are not likely to be able to get a timely injunction requiring the counterparty to allow you possession. Your best bet may be to request that the contract be terminated with return of your security deposit. If that is unavailing, find a friend who has some floor for you to sleep on until this crisis passes.
what can you do???? probably not much during the next month
