What are valid grounds for eviction?

A German landlord can only terminate a residential lease with ordinary notice if they have a legitimate interest—such as serious tenant breach, personal use (Eigenbedarf), or substantial economic harm—and must give written notice stating the specific ground.

A landlord in Ireland can terminate a tenancy only for specific reasons set out in law — such as rent arrears, breach of tenancy obligations, or the landlord needing the property for personal/family use — and must follow strict notice periods and procedures.
