Tenancy law: Clause: Painting the "windows and exterior doors from the inside" is invalid
On 18 July 2025, the Schwerin Local Court ruled that an unclear cosmetic repair clause in a tenancy agreement was invalid. As a result, the tenant was able to successfully reclaim her deposit and a credit balance from the utility bill. The judgement emphasises that rental agreements must be clearly worded, especially when it comes to the question of which renovation work the tenant must undertake. The court also clarified that although landlords must invest deposits securely and at an interest rate, they are not obliged to choose the institution with the highest interest rate. The decision strengthens the rights of tenants and at the same time shows landlords how important clear contractual clauses and proper management of the deposit are.
