⚠️ This is a sample agreement, not legal advice; consult a professional for important cases.

Most important: get the main landlord's permission to sublet — an unauthorised Untermiete can be grounds for termination.
Term ([BEFRISTUNG]): state clearly whether fixed-term (befristet bis …) or open-ended.
Specify whether rent includes utilities; give an IBAN.
Print two copies, both parties sign.
Fill every [BRACKET].
