If you have a Tenancy Agreement (“Tenancy”) signed between you and the tenant, it will be good to refer to it as the first point of reference.
Normally, for residential tenancies and depending on how the force majeure clauses in the tenancy agreement are drafted, the said provisions are usually not applicable for COVID-19 situation as they are often limited to events that result in property damage rendering the property unfit for occupation. In the absence of contractual rights to do so, the tenant cannot refuse to pay rent and can only negotiate with you in good faith to defer, reduce or waive the rent in view of the COVID-19 pandemic.
Since the tenant has removed all his belongings, there may be no point to apply for a warrant of distress to recover rent. Do check Tenancy to see if there is any recourse in the event of default in payment of rent, for example, clause that allows you to forfeit the security deposit paid by the tenant. You may also consider getting a lawyer to assist you to issue letter of demand to recover the default rental together with late payment interest specified in the tenancy agreement.
However, do note that you may need to weigh in on the practical matter of ‘cost’, whether it is worth the amount spend on legal cost to recover the sum owed or enforce your legal rights (if any), especially if your tenant has already returned to Libya, where you may need to engage a lawyer from Libya to assist in the enforcement.
