Sublease Agreement Template – Digital Contract for Shared Flats & Apartments

What belongs in a complete sublease contract?

A sublease agreement regulates the legal relationship between the main tenant of an apartment and the subtenant. To avoid future disputes, all essential terms should be put in writing. In addition to the names of the contracting parties, this includes the exact description of the sublet rooms and the usage rights for shared areas like the kitchen, bathroom, or hallway.

Accurately regulating financial aspects is equally crucial. The rent amount, utility arrangements, and the security deposit refund terms must be clearly defined. Agreements regarding furniture and the number of keys handed over should also be part of any complete agreement.

Rights and Obligations: The Landlord's Consent

Anyone wishing to sublet living space must familiarize themselves with the legal requirements beforehand. Under German law (§ 540 BGB), subletting to a third party without the landlord's explicit permission is generally not permitted. Unauthorized subletting can have severe consequences, including immediate termination of the primary lease.

However, the law distinguishes between subletting the entire apartment and subletting only a portion of it (e.g., a single room). For partial sublets, main tenants often have a legal claim to the landlord's permission under § 553 BGB, provided they can demonstrate a legitimate interest, such as financial or personal reasons.

Common mistakes when subletting

In practice, conflicts usually arise from incomplete agreements or avoidable formal errors. Verbal agreements are difficult to prove in court. Common mistakes include:

To avoid these pitfalls, we recommend using a structured digital template that guides you through all relevant points step-by-step.

• Failing to obtain the landlord's consent before the subtenant moves in
• Vague utility cost agreements (flat rate vs. actual consumption billing)
• Missing inventory list for furnished rooms
• No written documentation of the room's condition and keys during handover
