Lawyer specializing in terms and conditions

Legally sound Terms and Conditions for businesses, online stores, SaaS providers, and digital platforms—drafted, reviewed, and enforced by attorney Heval Mienert, nationwide.

What are the Terms and Conditions?

General Terms and Conditions (GTC) are pre-formulated contractual terms used in a wide variety of contracts, which one party presents to the other upon entering into a contract. They apply not only to e-commerce: service providers, SaaS providers, agencies, and B2B companies also use GTC to uniformly regulate payment terms, liability issues, rights of use, and warranties—thereby protecting themselves from legal risks. GTC are generally not an isolated, specialized topic, but rather part of contractual drafting, particularly in IT law and digital commerce.
German GTC law is strict. Case law regarding the validity of individual clauses is constantly evolving. Those who rely on boilerplate templates or fail to update their terms and conditions for years risk receiving cease-and-desist letters, having invalid clauses, and being subject to unfavorable statutory default provisions in the event of a dispute.
This includes, in particular:
  • Drafting and reviewing customized terms and conditions for online stores, platforms, SaaS products, and service providers
  • Drafting and reviewing other legal documents such as privacy policies, legal notices, terms of use, and cancellation policies
  • Drafting terms and conditions in the B2B sector, including conflicts between terms and conditions
  • Protection against cease-and-desist letters and defense against competition law claims due to invalid clauses
  • Legally compliant incorporation of terms and conditions into contracts and ongoing updates

Terms and Conditions for Digital Services

Online stores, SaaS products, and digital platforms have specific legal requirements for their terms and conditions. They often operate across borders, process personal data, and provide services continuously and automatically. Errors in the terms and conditions can quickly impact the entire business model.
Common Questions Regarding Terms and Conditions for Digital Services
Clients come to me with these questions:
  • What clauses do I need to ensure my online store is legally compliant?
  • How do I address usage rights in SaaS terms of service?
  • What liability provisions apply to digital platforms?
  • How do I draft terms and conditions that are GDPR-compliant and legally sound under competition law?
  • What applies if my customers are from different EU countries?
Terms and conditions for digital services often involve multiple areas of law: contract law, data protection law, distance selling law, competition law, and—in the case of AI-powered services—increasingly the EU AI Act as well. As a law firm specializing in IT law, I offer comprehensive legal support—without any gaps in coverage.

Why hire a lawyer who specializes in standard terms and conditions?

The law governing standard terms and conditions is a complex field of law. Case law regarding the validity of individual clauses is extensive and changes regularly. Anyone who drafts such terms without legal guidance or relies on free templates is taking on significant risks.
Timeliness and Legal Certainty
Terms and conditions must be continuously updated to reflect new laws and current case law. What was valid three years ago could now serve as grounds for a cease-and-desist letter. I will keep your terms and conditions up to date.
Customized design instead of a one-size-fits-all solution
General template agreements are rarely tailored to your specific business model. Customized terms and conditions take into account the nature of your services, your target audience, and your specific risks.
Protection against cease-and-desist letters
Invalid terms and conditions are often the subject of warnings under competition law. Drafting terms and conditions in a legally sound manner from the outset is significantly less costly than defending against claims after the fact.
The Intersection of IT Law and Contract Terms Law
When it comes to digital services, terms and conditions should never be viewed in isolation. Privacy policies, terms of use, liability provisions, and IT contracts are all interconnected. As a law firm specializing in IT law, I provide you with comprehensive advice.
Nationwide consulting
I advise clients in Berlin and across Germany via phone, video call, or in person. This way, you can receive legal assistance quickly and easily, no matter where you are.

Frequently Asked Questions About Terms and Conditions (FAQ)

What does a lawyer specializing in standard terms and conditions do?
A lawyer specializing in terms and conditions drafts customized terms and conditions, reviews existing terms and conditions for legal validity and up-to-date status, and provides advice regarding cease-and-desist letters related to invalid clauses. Legal guidance is particularly important for digital business models, as the law governing terms and conditions is complex and constantly evolving. If you are unsure whether your terms and conditions are still valid, please contact me.
Can I write my own terms and conditions?
In principle, yes. In practice, however, this is risky: German law governing standard terms and conditions is strict, and there is extensive case law regarding the validity of individual clauses. Anyone who relies on free templates risks including invalid clauses, receiving cease-and-desist letters, and, in the event of a dispute, being subject to unfavorable statutory default provisions. Having a lawyer draft the terms is the more cost-effective solution in the long run.
When are terms and conditions invalid?
Terms and conditions are invalid if they unreasonably disadvantage the other party to the contract. This often applies to excessive liability exclusions, unilateral rights to make changes, or non-transparent provisions; an unreasonable disadvantage can also arise simply because a clause is not worded clearly and comprehensibly. Invalid clauses have no legal effect; they are replaced by statutory provisions—which are often less favorable to you. We recommend having your terms and conditions reviewed before a dispute arises.
How much does it cost to have a lawyer draft terms and conditions?
The costs depend on the scope of the terms and conditions, the business model, and the amount of consulting work involved. For consumers, the statutory fee for an initial consultation—in the absence of a separate fee agreement—is generally a maximum of 190.00 euros, plus out-of-pocket expenses and sales tax. For businesses, the fee depends on the specific assignment. I would be happy to clarify what costs you can expect in your case during a non-binding initial consultation.
Are terms and conditions also binding in the B2B sector?
Yes, general terms and conditions can also be effectively incorporated into business transactions between companies. The law governing general terms and conditions is less strict in the B2B sector than it is when dealing with consumers, but there are limits here as well. Particular attention should be paid to what is known as a “conflict of general terms and conditions”—that is, a situation in which both contracting parties use their own general terms and conditions. I would be happy to advise you on this matter.
I received a warning letter regarding my terms and conditions—what should I do?
When you receive a cease-and-desist letter, prompt action is essential, as deadlines are typically short. Please contact me as soon as possible at 0152 09967225 or kontakt@kanzlei-mienert.de. I will review the letter, assess the likelihood of success, and advise you on how to proceed—whether by submitting a modified cease-and-desist declaration or by contesting the claims.
How often should terms and conditions be updated?
While there is no legal requirement, terms and conditions should always be reviewed whenever relevant laws change, new court rulings are issued, or your business model evolves. In practice, I recommend reviewing them every one to two years, as well as on an ad hoc basis in the event of major changes. I would be happy to assist you with this process.
