A landlord cannot evict a tenant arbitrarily. You must have valid legal grounds. Common reasons to send a legal notice to a tenant include: * **Non-Payment of Rent:** If the tenant has not paid rent for more than 15 days or as stipulated in the agreement. * **Expiry of Lease Agreement:** If the rental agreement has expired and the tenant refuses to renew or vacate. * **Breach of Contract:** Violation of terms like unauthorized subletting, keeping pets (if prohibited), or commercial use of residential property. * **Property Damage:** Causing structural damage or major alterations without permission. * **Personal Requirement:** The landlord genuinely needs the property for their own occupation (Bona Fide requirement). * **Nuisance:** Creating a nuisance for neighbors or conducting illegal activities on the premises.

To be legally valid and effective in court, your eviction notice must contain specific details: 1. **Clear Description:** Full address and description of the tenanted property. 2. **Tenancy Details:** Start date, current rent, and lease expiry date. 3. **Grounds for Eviction:** Clearly state *why* you are asking them to leave (e.g., Section 106 of Transfer of Property Act). 4. **Demand:** Specific demand to vacate and hand over peaceful possession. 5. **Notice Period:** A reasonable time to vacate (typically 15 to 30 days, depending on the law and agreement). 6. **Consequences:** Warning of civil suit and claim for damages/mesne profits if they fail to comply.

The legal process for eviction safeguards both landlord and tenant rights: 1. **Draft the Notice:** A lawyer drafts the notice citing relevant laws (Rent Control Act or TPA). 2. **Send via Registered Post:** It must be sent via Registered Post AD to prove delivery. 3. **Wait for Response:** The tenant is given time (e.g., 15-30 days) to reply or vacate. 4. **File an Eviction Suit:** If they refuse to leave, you file an eviction petition in the Rent Control Court or Civil Court. 5. **Court Order:** The court hears both sides and issues an eviction order if your grounds are valid. 6. **Execution:** If they still stay, police assistance can be sought to enforce the court order.
