Can I be evicted from a rented property in Malta without proper notice?

No, this does not sound consistent with proper procedure under the Private Residential Leases Act, which governs most residential tenancies in Malta and generally requires landlords to follow specific formal procedures and provide adequate notice periods before a tenant can be lawfully required to vacate a property, with the specific required notice period generally depending on factors such as the length of your tenancy and whether you're on a fixed-term or ongoing lease, meaning a verbal demand to leave within just a week, without proper formal notice, would generally not meet the legal requirements for a valid eviction. Unless there are specific serious grounds justifying a more urgent process, such as a serious breach of the lease on your part, a landlord generally cannot simply demand you leave on short informal notice, and you should not feel obligated to vacate based solely on this kind of verbal ultimatum without first understanding your actual legal position under your specific lease and the applicable statutory notice requirements. Given the urgency and the potential seriousness of your housing situation being disrupted, it would be important to contact the Housing Authority promptly, which oversees residential lease disputes in Malta, and consider seeking urgent legal advice to properly understand your rights and, if needed, formally push back on this improper attempted eviction.
