Start-up euphoria, innovative ideas, and technical know-how are the ingredients for many start-up success stories. However, the legal challenges awaiting founders from the very beginning are regularly underestimated. Neglecting these risks can lead to warnings, costly corrections, disputes among parties, and, in the worst case, the failure of the business idea.
Considering current legal requirements and recent case law, this overview highlights the most common legal pitfalls for start-ups. Practical tips on how to avoid these legal challenges for start-ups are also included.
Common Legal Mistakes Made by Start-ups and How to Avoid Them
Mandatory Information: Impressum & Digital Services Act (DDG) Compliance
When the Digital Services Act (DDG) came into force in July 2024, the requirements for provider identification were revised. The classic imprint obligation (Section 5 TMG) has been incorporated into Section 5 DDG. Frequently, complete details of the responsible persons or the correct entry of register and VAT data are missing. This applies not only to traditional websites, but also to social media sites, apps, and online stores. For a deeper understanding of new regulations, see our article on the Digital Services Act (DSA).
Solution:
- Provide mandatory information in accordance with Section 5 DDG in full and in an easily accessible manner.
- Always keep the legal notice and privacy policy up to date, even if the legal form or address changes.
- Do not forget mandatory information for LinkedIn, Instagram, and other profiles.
Practical tip: Many start-ups use modular systems or agencies. It is crucial to verify whether the provided imprint generators truly meet the current legal requirements.
Trademark Law and Company Names: Essential Protection for Start-ups
Company names, product designations, and logos are often used without prior trademark research or strategic protection. If it is later discovered that identical or similar signs are already protected, there is a significant risk of warnings, injunctions, and even claims for damages. This risk is frequently neglected, especially in the seed phase. Comprehensive trademark protection for start-ups is therefore indispensable.
Solution:
- Before choosing a company name and logo, conduct a thorough search in the registers of the DPMA and the EUIPO.
- Register trademarks at an early stage to prevent future conflicts.
- Consider international classes and property rights for potential future expansion.
Practical tip: The registration of a domain alone does not indicate the availability of the name from a trademark law perspective. Domains and trademarks must be considered separately.
Founder Agreements and Articles of Association: Avoiding Future Disputes
Many start-ups commence with verbal or only superficially written agreements. However, disputes about shares, vesting, or responsibilities are then often inevitable during the growth phase. These shortcomings become painfully apparent when investors join or when the company exits. Understanding the binding effect and design of term sheets for startup investments can mitigate such risks.
Solution:
- Clearly and comprehensively document articles of association and shareholders’ agreements in writing.
- Include clauses for vesting regulations, exit scenarios, non-competition clauses, and confidentiality.
- Make arrangements for the transfer of shares at an early stage.
Practical tip: Not only the existence of a founder agreement, but especially its meticulous content, determines subsequent legal certainty.
Accurate Business Address & Reporting Obligations for Start-ups
Address changes, changes of registered office, or changes of name must be updated not only in the commercial register but also at the tax office, trade office, and on all online presences. Omissions in these areas occur regularly and can lead to legal issues for start-ups.
Solution:
- Immediately notify all relevant authorities of any changes.
- Check whether general terms and conditions, legal notices, and contracts also require adaptation.
Practical tip: Many funding programs, banks, or partners verify the correctness of register data before concluding contracts.
Data Protection Compliance: A Key Challenge for Start-ups
The GDPR and recent rulings (e.g., on the integration of tracking tools, AI services, or international cloud providers) have further increased data protection requirements. The legally compliant design of processes is essential, particularly for innovative, data-driven business models. For companies relying on external services, understanding data protection when using cloud services is critical.
Solution:
- Maintain a processing directory and conduct a data protection impact assessment.
- Tailor the privacy policy to the individual business model.
- Conclude Data Processing Agreements (DPAs) with all service providers.
- Integrate data protection principles during new product development (privacy by design).
Practical tip: Data protection risks should also be identified early when using open-source software, chatbots, or AI services.
Timely Commercial Register Entries: Avoiding Personal Liability
Corporations, such as GmbH or UG, may only engage in legal transactions once they have been entered in the commercial register. Disregarding this can lead to personal liability for founders, and contracts in the start-up phase may often be invalid.
Solution:
- Await entry in the commercial register and proper publication before engaging in significant transactions.
- No transactions should be conducted on behalf of the company prior to its registration.
Practical tip: Changes to the management, registered office, or object of the company must also be entered immediately.
Securing Intellectual Property: Rights to Software, Designs & Content
It is particularly problematic when freelancers, agencies, or working students are involved in development without clear agreements. If there is no explicit transfer of usage rights, these rights remain with the author. This can lead to complex issues regarding ownership of software and other creative works.
Solution:
- In all contracts with external developers and agencies, regulate the transfer of all rights of use in writing, clearly referencing § 31 UrhG.
- Subsequent clarification is usually time-consuming and expensive.
Practical tip: Even with open-source licenses, it is essential to check whether and to what extent commercial use and modification are permitted.
Correct General Terms and Conditions (GTC) & Consumer Information
Online retailers, in particular, are subject to extensive information and instruction obligations. Incorrect or outdated general terms and conditions, unclear liability regulations, or missing revocation instructions can lead to warning risks and legal uncertainties. It is important to know why providers of SaaS or online stores should not ask their users to agree to terms and conditions or privacy policies in certain ways.
Solution:
- Have customized general terms and conditions created.
- Adapt sample texts to the specific business model and target group (B2B/B2C).
- Comply with consumer rights and distance selling regulations.
Practical tip: Free samples from the Internet are rarely up-to-date and almost never tailored to your specific business model.
Social Security & Labor Law Obligations: What Start-ups Need to Know
Employees must be correctly registered and accounted for. It is particularly common for cases of bogus self-employment among freelancers to go unrecognized or for the Minimum Wage Act to be ignored. The consequences include back payments, fines, and, in extreme cases, even criminal prosecution.
Solution:
- Verify the status (employee vs. self-employed) of all individuals working for the company.
- Comply with social security, tax office, and employers’ liability insurance association reporting obligations.
- Formulate employment contracts clearly and unambiguously.
Practical tip: Interns and working students must also be registered, depending on the type of activity.
Limitation of Liability & Insurance: Protecting Your Start-up
Liability risks are often underestimated in the initial phase of a start-up. Errors during development, defective products, or breaches of contract can quickly threaten a company’s existence.
Solution:
- Assess and procure appropriate business and financial loss liability insurance.
- Clearly regulate limitations of liability in contracts and general terms and conditions.
- Regularly reassess risks, particularly in the event of product adjustments or expansion.
Practical tip: In the case of a GmbH, the limitation of liability to the company’s assets only provides protection if the formal and actual separation of private and company assets is consistently observed.
Bonus: Other Typical Sources of Error in Everyday Start-up Life
- Failure to comply with tax obligations: Deadlines for advance VAT returns, profit determination, and annual financial statements are often missed.
- Incorrect funding applications: Inaccurate or late information can lead to the reclaiming of funding.
- Insufficient documentation for investor rounds: Cap tables, shareholder lists, and convertible loans must be kept transparent. Proper legal preparation for the first investment round is crucial.
