A tenant who has occupied a property for 40 years can still be evicted if they have defaulted on rent payments for a significant period like 11 years, as long as the landlord follows proper legal procedures and proves the willful default in rent payments; the length of tenancy does not automatically grant immunity from eviction for non-payment of rent.
The landlord needs to provide concrete evidence of the tenant's non-payment of rent over the 11-year period, including rent receipts, notices, and communication records.
A landlord can technically claim rental arrears for the last 11 years, but due to the limitation period under the law, they can only legally pursue arrears for a specific time frame, usually three years from the date the rent became due that to only the rental amount what had been paid so far and not the enhanced rental amount. ,
The tenant, if being forced to vacate, he can file a suit for permanent injunction against the landlord to restrain him from forcibly evicting the tenant without following the due process of law.
