Commercial Lease Requirements in Bavaria: Written Form and Key Clauses

Commercial lease agreements in Germany are far more complex than residential contracts, often running dozens of pages with extensive annexes. The single most dangerous pitfall for landlords is the written form requirement — a technicality that can transform a secure 10-year fixed-term lease into one terminable at 6 months' notice.

The Critical Written Form Rule (§ 550 BGB)

The Rule

Any lease intended to last longer than one year must be in strict written form (§ 126 BGB):

• Both parties must sign the same physical document (wet-ink signatures)
• Digital signatures (DocuSign, email confirmations) do not satisfy the requirement
• All essential terms must be discernible from the signed document

The Consequence of Non-Compliance

If any essential term fails to meet the written form requirement, the entire fixed-term lease is automatically deemed to have been concluded for an indefinite period — meaning either party can terminate with just ~6 months' notice.

This risk (known as Schriftformkündigung) is one of the biggest threats to commercial property investment in Bavaria: a tenant can exploit even a minor form defect to exit a long-term lease prematurely.

What Must Be in the Signed Document

Highest risk area: Later amendments made informally (email agreements, verbal modifications, side letters not properly attached to the original document) are the most common cause of form defects.

Healing Clauses Are Void

The German Federal Court (BGH, 2017) ruled that contractual clauses designed to "heal" form defects or prevent parties from exploiting them (Schriftformheilungsklauseln) are void and unenforceable. Form defects cannot be contractually mitigated.

Key Commercial Lease Clauses

Due to the absence of mandatory tenant protections, commercial leases must explicitly address:

1. Operating cost allocation: Define the full scope of pass-through costs (often Triple-Net/NNN structure)
2. Maintenance obligations: Specify who is responsible for "Dach und Fach" (roof and structure) — see Commercial Maintenance
3. Competition protection waiver: Explicitly exclude or limit the implied duty not to lease to competitors
4. Reinstatement obligations: Define restoration requirements at lease end (return to shell condition, removal of fit-outs)
5. Subletting provisions: Commercial subletting restrictions and consent requirements
6. Permitted use: Precisely define the allowed commercial activity

How Landager Helps
