Contract Law & Contract Drafting: Your Secure Anchor in Business Transactions
A contract is more than just paper — it is the foundation of your commercial freedom. Just as in surfing big waves, the same applies in business: those who venture into stormy waters need excellent equipment and a clear plan. A poorly drafted contract is like a leaky leash — when it matters most, it won’t hold.
At Reef Rechtsanwälte, we combine legal precision with the pragmatism of entrepreneurship. We ensure that your contracts are not only legally sound, but also enforce your commercial interests — without slowing down the deal.
Why professional contract drafting is business-critical
German contract law is based on the principle of freedom of contract. You can agree to whatever you wish — as long as you do not violate laws or “good morals”. But this is precisely where the hidden shallows lie: what at first glance appears to be a fair arrangement between merchants can quickly be overturned in court as an invalid standard terms clause.
The Misconception of Freedom of Form
As a general rule, freedom of form applies. Contracts can be concluded with a handshake, by email, or even via WhatsApp.
The risk: Without documentation, there is a lack of evidence in the event of a dispute. Furthermore, the law requires notarial form for certain transactions (e.g. real estate purchases under § 311b BGB, GmbH shares). A failure to comply with formal requirements leads to invalidity (§ 125 BGB) — the entire deal is void from the outset.
The 4 Most Dangerous Clause Traps (Update 2025)
The case law of the Federal Court of Justice (BGH) has tightened the reins on companies massively in recent years — and particularly up to 2025. What was once standard practice is now frequently invalid.
1. The “Written Form Cure Clause” in Lease Law
Many commercial lease agreements contain the clause: “The parties undertake to rectify any defects in written form at any time and not to terminate the contract for that reason.”
Legal position: These clauses are invalid. The BGH has ruled that such a clause violates mandatory law (§ 550 BGB) (cf. BGH, judgment of 27.09.2017 – XII ZR 114/16).
Consequence: A long-term lease can suddenly be terminated on ordinary notice overnight if an addendum (e.g. a rent increase) was not properly documented in the required form.
2. Deemed Consent to Standard Terms Amendments
Banks and service providers used it for years: “Amendments to the standard terms shall be deemed approved if you do not object within 6 weeks.”
Legal position: The BGH has declared this practice invalid, as it treats the customer’s silence as consent in an abusive manner (BGH, judgment of 27.04.2021 – XI ZR 26/20). This principle also applies in the B2B context where amendments affect the balance of the contract.
Solution: Material changes require genuine, active consent (opt-in).
3. Blanket Liability Exclusions
A “disclaimer for any and all damages” is not worth the paper it is written on.
Legal position: Liability for intent, gross negligence, and personal injury can never be excluded. In B2B transactions, the exclusion of liability for cardinal obligations (essential contractual duties on which a party relies) is also invalid.
Tip: Use precise liability caps oriented to the contract value rather than blanket exclusions.
4. Automatic Contract Renewals
A recent landmark ruling from Karlsruhe (BGH, judgment of 10.07.2025 – III ZR 61/24): renewal clauses in ongoing contractual relationships (e.g. telecommunications, maintenance) that bind the customer for more than 24 months from the point of renewal are invalid. The binding period must be transparent and moderate.

The Reef Legal Contract Check: The Process of a Professional Contract Review
Phase 1: Risk Radar
We clarify what is at stake commercially. A €500 deal requires different clauses than a million-euro exit.
Phase 2: Deep Dive (Standard Terms Review)
We scan your drafts for red flags. We apply the strict standard of §§ 305 ff. BGB. Because: B2B contracts are also subject to standard terms control as soon as one party sets the conditions.
Phase 3: Safe Harbour
We draft legally sound alternatives and support you in the negotiation until the contract is ready to sign.

FAQ – Frequently Asked Questions on Contract Law
When are standard terms effectively incorporated in B2B transactions?
Unlike with consumers, standard terms do not need to be expressly “handed over” to business counterparts. However, a mere reference on an invoice is often insufficient. BGH case law requires a clear reference at the time of contracting and an opportunity to take notice of the terms. Silence in response to a written commercial confirmation can lead to their incorporation; silence in response to an offer, however, generally cannot.
What is a severability clause and do I need one?
The classic clause “Should any provision be invalid, a valid provision shall be deemed agreed…” is itself often invalid in standard terms, as it violates the transparency requirement. Better: rely on § 306 BGB (statutory default) or use modern formulations accepted by the BGH that do not fictitiously imply a “saving reduction”.
Do email commitments constitute a contract?
Yes, provided that written form has not been agreed upon or required by law. An email satisfies the “text form” requirement (§ 126b BGB). Caution with notices of termination: employment contracts, and often lease agreements too, mandatorily require “written form” (original signature on paper). A termination by email is therefore invalid in these cases.
