While grounds vary by state (e.g., Delhi vs. Maharashtra), common valid reasons for eviction include: * **Bona Fide Requirement:** You honestly need the property for yourself or your family members. * **Subletting:** Tenant has sublet the property without your written consent. * **Non-Use:** Tenant has not resided in the property for a continuous period (e.g., 6 months). * **Acquisition of Alternate Property:** Tenant has bought or built their own residence in the same city. * **Material Alterations:** Tenant made structural changes without permission. * **Nuisance & Illegal Use:** Using residential property for commercial purposes or illegal activities.

It's crucial to understand the difference: * **Termination of Tenancy:** This is the act of ending the lease agreement (e.g., by sending a Section 106 notice under Transfer of Property Act). * **Eviction:** This is the process of recovering physical possession *after* the tenancy has been terminated. * **The Rule:** You cannot file for eviction unless you have first validly terminated the tenancy through a legal notice.

If the tenant ignores your notice: 1. **File Petition:** Submit an eviction petition in the Rent Control Court / Civil Court. 2. **Summons:** Court sends summons to the tenant. 3. **Written Statement:** Tenant files their defense. 4. **Evidence:** Both parties prove their claims (rent receipts, agreement, photos). 5. **Arguments & Judgment:** Court passes an eviction decree. 6. **Execution:** If tenant still refuses, court bailiff helps take possession.
