Turkish residential-lease law strongly favours the tenant. To evict, the landlord must fit the case within a closed statutory list.
Landlord-side grounds
Personal occupation need (the landlord, parents or descendants), reconstruction or major renovation, business need.
Tenant-side grounds
Two warned non-payments of rent, use for an unpermitted purpose, unauthorised sublease, damage to the property, serious misconduct.
"Two warnings" trap
If the tenant pays rent late twice in the same year despite formal notices, the landlord can evict — even if both rents are eventually paid.
Eviction undertaking (tahliye taahhüdü)
An undertaking signed AFTER the lease begins is enforceable. One signed before is void.
