Yes, landlords can evict tenants without a lease, but they must follow legal procedures. Even without a written agreement, landlords must provide proper notice and valid reasons for eviction, such as non-payment of rent or lease violations. Unlawful eviction attempts, without adherence to legal protocols, can lead to legal repercussions. Tenants have rights against arbitrary eviction, and landlords must navigate legal channels to enforce an eviction, ensuring a fair and lawful process that protects both parties' interests.
