Can my landlord evict me without going to court?

No — what your landlord is threatening is illegal. A landlord cannot forcibly evict a tenant, change the locks, or remove belongings without a court order, regardless of how the lease dispute arose. This is often called "self-help eviction" and it is not permitted under Indian law; landlords must go through the proper legal process even if they have valid grounds to want you out.

The correct process depends on your state's rent control or tenancy laws, but broadly involves the landlord issuing a legal notice terminating the tenancy (typically giving the notice period specified in your rent agreement or the applicable state Rent Control Act), and if you do not vacate voluntarily after that, filing an eviction suit before the appropriate rent controller or civil court. Only after the court passes an eviction order, and if you still don't comply, can the property be repossessed through court-supervised process — never by the landlord directly.

If your landlord follows through on the threat to change locks or remove your belongings without a court order, this can amount to criminal trespass and mischief under the applicable law, and you can file a police complaint immediately. You can also approach the civil court for an injunction restraining him from taking forcible action, which courts grant fairly readily in genuine cases of threatened illegal eviction.

I'd suggest sending your landlord a written response citing that forcible eviction without due process is unlawful, keeping copies of all communication, and if he proceeds anyway, going straight to the police and a lawyer for an urgent injunction rather than waiting — these situations tend to escalate quickly.
