Commercial lease agreements in Saxony-Anhalt are largely shaped by the parties themselves — but this freedom is bounded by a small number of legally mandatory rules and market conventions that can, if violated, silently undermine even a meticulously negotiated transaction. The single greatest risk for commercial landlords is the written form rule under § 550 BGB.

1. The Written Form Requirement (§ 550 BGB) — Critical Risk
The Rule
Any residential or commercial lease intended to run for more than one year must be documented in written form (§ 126 BGB — handwritten signature, original document). A lease failing to meet this requirement is automatically treated as indefinite, meaning either party can terminate with approximately 6 months' notice at any time — regardless of the negotiated fixed term.
The Threat in Practice
For a long-term commercial lease in Saxony-Anhalt (e.g., 10 years), a written form defect can arise from:
- A lease or annex not physically signed by all parties with original ink signatures on the same document or a counterpart properly referencing each other
- A verbal or email-only supplement to the lease (rent-free period, adjusted handover date, extra parking included) that is never documented in a signed written rider
- A formal assignment of the lease without a properly executed assumption agreement
The BGH has repeatedly rejected "written form healing clauses" — contractual provisions stating that parties waive their right to terminate based on written form defects. These are of no legal effect.
Best Practices to Protect Your Lease
- All supplements must be in formal writing with original signatures linking back to and referencing the main lease
- Conduct a written form audit before selling the property — a buyer who discovers a defect can immediately threaten termination as a renegotiation tactic
- Consider using qualified electronic signatures (QES), which are the only digital signature format that satisfies § 126 BGB's written form requirement
2. VAT Option (Umsatzsteuer — Optierung nach § 9 UStG)
Commercial property rental is VAT-exempt by default in Germany. However, landlords may elect to charge VAT (Optierung) on commercial leases, provided:
- The tenant uses the premises exclusively for activities giving rise to input tax deduction (i.e., the tenant is a fully VAT-registered business)
- The option is clearly documented in the lease
Why Option to VAT?
- The landlord gains full input tax recovery on all building-related expenditure (construction, renovation, maintenance), reducing effective building costs
- Loss of the option (because the tenant subsequently conducts VAT-exempt activities) triggers claw-back of input VAT over a 10-year adjustment period — a potentially enormous liability
Protective Clause: Include an express warranty by the tenant that they will only conduct VAT-generating activities, plus a right to terminate or claim damages if this warranty is breached.
3. Operating Cost Structures (Net/Double-Net/Triple-Net)
German commercial leases may allocate virtually all operating costs — and depending on how they are drafted, maintenance costs — to the tenant. These structures range from:
| Structure | Tenant's Obligations |
|---|---|
| Gross lease | Pays base rent only — landlord absorbs all costs |
| Net lease | Base rent + property tax (Grundsteuer) |
| Double-net | Base rent + property tax + building insurance |
| Triple-net (NNN) | All above + all maintenance and repairs |
AGB Risk with NNN: Triple-net clauses transferring all structural maintenance (including age-related renewal of structural elements) to the tenant are frequently challenged as unfair AGB terms — unless individually negotiated with documented evidence of genuine bargaining (e.g., below-market rent as consideration). Courts, including those in Saxony-Anhalt, follow BGH doctrine requiring these to be true individual agreements, not boilerplate.
4. Competition Protection (Konkurrenzschutz)
The BGH has established that every commercial landlord implicitly warrants that they will not actively jeopardize the tenant's business by leasing adjacent space to a direct competitor. This implied competition protection may even extend across a multi-building complex.
To avoid ambiguity:
- If you want to exclude competition protection — explicitly do so in the lease
- If both parties agree on a defined scope of protection — specify the precise product categories or services it covers
5. Reinstatement Obligations
Commercial tenants who have fitted out demised premises are typically required to reinstate them (remove all fit-out, return to shell-and-core) at the end of the lease. These obligations must be:
- Clearly defined in the lease
- Proportionate — courts may limit disproportionate reinstatement demands as AGB violations
How Landager Helps
Written form compliance is the most dangerous ongoing risk in commercial property management. Landager maintains a structured document repository linking all lease supplements and riders to the master lease, with timestamps and e-signature audit trails. The platform alerts you when any lease modification — however minor — requires a formal written rider to preserve the original fixed term.
